3 Simple Habits to Improve Your Critical Thinking

• Helen Lee Bouygues

But simple doesn’t mean easy.

Too many business leaders are simply not reasoning through pressing issues, and it’s hurting their organizations.  The good news is that critical thinking is a learned behavior. There are three simple things you can do to train yourself to become a more effective critical thinker: question assumptions, reason through logic, and diversify your thought and perspectives. They may sound obvious, but deliberately cultivating these three key habits of mind go a long way in helping you become better at clear and robust reasoning.

A few years ago, a CEO assured me that his company was the market leader. “Clients will not leave for competitors,” he added. “It costs too much for them to switch.” Within weeks, the manufacturing giant Procter & Gamble elected not to renew its contract with the firm. The CEO was shocked — but he shouldn’t have been.

How to think effectively: Six stages of critical thinking

Credit: Elder / Paul

• Researchers propose six levels of critical thinkers: Unreflective thinkers, Challenged thinkers, Beginning thinkers, Practicing thinkers, Advanced thinkers, and Master thinkers.
• The framework comes from educational psychologists Linda Elder and Richard Paul.
• Teaching critical thinking skills is a crucial challenge in our times.

The coronavirus has not only decimated our populations, its spread has also attacked the very nature of truth and stoked inherent tensions between many different groups of people, both at local and international levels. Spawning widespread conspiracy theories and obfuscation by governments, the virus has also been a vivid demonstration of the need for teaching critical thinking skills necessary to survive in the 21st century. The stage theory of critical thinking development, devised by psychologists Linda Elder and Richard Paul , can help us gauge the sophistication of our current mental approaches and provides a roadmap to the thinking of others.

The researchers identified six predictable levels of critical thinkers, from ones lower in depth and effort to the advanced mind-masters, who are always steps ahead.

As the scientists write , moving up on this pyramid of thinking “is dependent upon a necessary level of commitment on the part of an individual to develop as a critical thinker.” Using your mind more effectively is not automatic and “is unlikely to take place “subconsciously.” In other words – you have to put in the work and keep doing it, or you’ll lose the faculty.

Here’s how the stages of intellectual development break down:

Unreflective thinker

These are people who don’t reflect about thinking and the effect it has on their lives. As such, they form opinions and make decisions based on prejudices and misconceptions while their thinking doesn’t improve.

Unreflective thinkers lack crucial skills that would allow them to parse their thought processes. They also do not apply standards like accuracy, relevance, precision, and logic in a consistent fashion.

How many such people are out there? You probably can guess based on social media comments. As Elder and Paul write , “it is perfectly possible for students to graduate from high school, or even college, and still be largely unreflective thinkers.”

Challenged thinker

This next level up thinker has awareness of the importance of thinking on their existence and knows that deficiencies in thinking can bring about major issues. As the psychologists explain, to solve a problem, you must first admit you have one.

People at this intellectual stage begin to understand that “high quality thinking requires deliberate reflective thinking about thinking”, and can acknowledge that their own mental processes might have many flaws. They might not be able to identify all the flaws, however.

A challenged thinker may have a sense that solid thinking involves navigating assumptions, inferences, and points of view, but only on an initial level. They may also be able to spot some instances of their own self-deception. The true difficulty for thinkers of this category is in not “believing that their thinking is better than it actually is, making it more difficult to recognize the problems inherent in poor thinking,” explain the researchers.

Thinkers at this level can go beyond the nascent intellectual humility and actively look to take control of their thinking across areas of their lives. They know that their own thinking can have blind spots and other problems and take steps to address those, but in a limited capacity.

Beginning thinker

Beginning thinkers place more value in reason, becoming self-aware in their thoughts. They may also be able to start looking at the concepts and biases underlying their ideas. Additionally, such thinkers develop higher internal standards of clarity, accuracy and logic, realizing that their ego plays a key role in their decisions.

Another big aspect that differentiates this stronger thinker – some ability to take criticism of their mental approach, even though they still have work to do and might lack clear enough solutions to the issues they spot.

Practicing thinker

This more experienced kind of thinker not only appreciates their own deficiencies, but has skills to deal with them. A thinker of this level will practice better thinking habits and will analyze their mental processes with regularity.

While they might be able to express their mind’s strengths and weaknesses, as a negative, practicing thinkers might still not have a systematic way of gaining insight into their thoughts and can fall prey to egocentric and self-deceptive reasoning.

How do you get to this stage? An important trait to gain, say the psychologists, is “intellectual perseverance.” This quality can provide “the impetus for developing a realistic plan for systematic practice (with a view to taking greater command of one’s thinking).”

“We must teach in such a way that students come to understand the power in knowing that whenever humans reason, they have no choice but to use certain predictable structures of thought: that thinking is inevitably driven by the questions, that we seek answers to questions for some purpose, that to answer questions, we need information, that to use information we must interpret it (i.e., by making inferences), and that our inferences, in turn, are based on assumptions, and have implications, all of which involves ideas or concepts within some point of view,” explain Elder and Paul.

One doesn’t typically get to this stage until college and beyond, estimate the scientists. This higher-level thinker would have strong habits that would allow them to analyze their thinking with insight about different areas of life. They would be fair-minded and able to spot the prejudicial aspects in the points of view of others and their own understanding.

While they’d have a good handle on the role of their ego in the idea flow, such thinkers might still not be able to grasp all the influences that affect their mentality.

Advanced thinker

The advanced thinker is at ease with self-critique and does so systematically, looking to improve. Among key traits required for this level are “intellectual insight” to develop new thought habits, “ intellectual integrity” to “recognize areas of inconsistency and contradiction in one’s life,” intellectual empathy ” to put oneself in the place of others in order to genuinely understand them, and the “ intellectual courage” to confront ideas and beliefs they don’t necessarily believe in and have negative emotions towards.

Master thinker

This is the super-thinker, the one who is totally in control of how they process information and make decisions. Such people constantly seek to improve their thought skills, and through experience “regularly raise their thinking to the level of conscious realization.”

A master thinker achieves great insights into deep mental levels, strongly committed to being fair and gaining control over their own egocentrism.

Such a high-level thinker also exhibits superior practical knowledge and insight, always re-examining their assumptions for weaknesses, logic, and biases.

And, of course, a master thinker wouldn’t get upset with being intellectually confronted and spends a considerable amount of time analyzing their own responses.

“Why is this so important? Precisely because the human mind, left to its own, pursues that which is immediately easy, that which is comfortable, and that which serves its selfish interests. At the same time, it naturally resists that which is difficult to understand, that which involves complexity, that which requires entering the thinking and predicaments of others,” write the researchers.

So how do you become a master thinker? The psychologists think most students will never get there. But a lifetime of practicing the best intellectual traits can get you to that point when “people of good sense seek out master thinkers, for they recognize and value the ability of master thinkers to think through complex issues with judgment and insight.”

The significance of critical thinking in our daily lives, especially in these confusing times, so rife with quick and often-misleading information, cannot be overstated. The decisions we make today can truly be life and death.

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment.

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o’clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68–69; 1933: 91–92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot’s position, it must appear to project far out in front of the boat. Moreover, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69–70; 1933: 92–93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond lane from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses. As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009, 2021), others on the resulting judgment (Facione 1990a), and still others on responsiveness to reasons (Siegel 1988). Kuhn (2019) takes critical thinking to be more a dialogic practice of advancing and responding to arguments than an individual ability.

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in spacing in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the spacing of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016a) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Facione (1990a: 25) divides “affective dispositions” of critical thinking into approaches to life and living in general and approaches to specific issues, questions or problems. Adapting this distinction, one can usefully divide critical thinking dispositions into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking. In three studies, Haran, Ritov, & Mellers (2013) found that actively open-minded thinking, including “the tendency to weigh new evidence against a favored belief, to spend sufficient time on a problem before giving up, and to consider carefully the opinions of others in forming one’s own”, led study participants to acquire information and thus to make accurate estimations.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), Black (2012), and Blair (2021).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work. It is also helpful to be aware of the prevalence of “noise” (unwanted unsystematic variability of judgments), of how to detect noise (through a noise audit), and of how to reduce noise: make accuracy the goal, think statistically, break a process of arriving at a judgment into independent tasks, resist premature intuitions, in a group get independent judgments first, favour comparative judgments and scales (Kahneman, Sibony, & Sunstein 2021). It is helpful as well to be aware of the concept of “bounded rationality” in decision-making and of the related distinction between “satisficing” and optimizing (Simon 1956; Gigerenzer 2001).

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? In a comprehensive meta-analysis of experimental and quasi-experimental studies of strategies for teaching students to think critically, Abrami et al. (2015) found that dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), Bailin et al. (1999b), and Willingham (2019).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

What is Critical Thinking?

Critical thinking is the ability to think clearly and rationally, understanding the logical connection between ideas.  Critical thinking has been the subject of much debate and thought since the time of early Greek philosophers such as Plato and Socrates and has continued to be a subject of discussion into the modern age, for example the ability to recognise fake news .

Critical thinking might be described as the ability to engage in reflective and independent thinking.

In essence, critical thinking requires you to use your ability to reason. It is about being an active learner rather than a passive recipient of information.

Critical thinkers rigorously question ideas and assumptions rather than accepting them at face value. They will always seek to determine whether the ideas, arguments and findings represent the entire picture and are open to finding that they do not.

Critical thinkers will identify, analyse and solve problems systematically rather than by intuition or instinct.

Someone with critical thinking skills can:

Understand the links between ideas.

Determine the importance and relevance of arguments and ideas.

Recognise, build and appraise arguments.

Identify inconsistencies and errors in reasoning.

Approach problems in a consistent and systematic way.

Reflect on the justification of their own assumptions, beliefs and values.

Critical thinking is thinking about things in certain ways so as to arrive at the best possible solution in the circumstances that the thinker is aware of. In more everyday language, it is a way of thinking about whatever is presently occupying your mind so that you come to the best possible conclusion.

Critical Thinking is:

A way of thinking about particular things at a particular time; it is not the accumulation of facts and knowledge or something that you can learn once and then use in that form forever, such as the nine times table you learn and use in school.

The Skills We Need for Critical Thinking

The skills that we need in order to be able to think critically are varied and include observation, analysis, interpretation, reflection, evaluation, inference, explanation, problem solving, and decision making.

Specifically we need to be able to:

Think about a topic or issue in an objective and critical way.

Identify the different arguments there are in relation to a particular issue.

Evaluate a point of view to determine how strong or valid it is.

Recognise any weaknesses or negative points that there are in the evidence or argument.

Notice what implications there might be behind a statement or argument.

Provide structured reasoning and support for an argument that we wish to make.

The Critical Thinking Process

You should be aware that none of us think critically all the time.

Sometimes we think in almost any way but critically, for example when our self-control is affected by anger, grief or joy or when we are feeling just plain ‘bloody minded’.

On the other hand, the good news is that, since our critical thinking ability varies according to our current mindset, most of the time we can learn to improve our critical thinking ability by developing certain routine activities and applying them to all problems that present themselves.

Once you understand the theory of critical thinking, improving your critical thinking skills takes persistence and practice.

Try this simple exercise to help you to start thinking critically.

Think of something that someone has recently told you. Then ask yourself the following questions:

Who said it?

Someone you know? Someone in a position of authority or power? Does it matter who told you this?

What did they say?

Did they give facts or opinions? Did they provide all the facts? Did they leave anything out?

Where did they say it?

Was it in public or in private? Did other people have a chance to respond an provide an alternative account?

When did they say it?

Was it before, during or after an important event? Is timing important?

Why did they say it?

Did they explain the reasoning behind their opinion? Were they trying to make someone look good or bad?

How did they say it?

Were they happy or sad, angry or indifferent? Did they write it or say it? Could you understand what was said?

What are you Aiming to Achieve?

One of the most important aspects of critical thinking is to decide what you are aiming to achieve and then make a decision based on a range of possibilities.

Once you have clarified that aim for yourself you should use it as the starting point in all future situations requiring thought and, possibly, further decision making. Where needed, make your workmates, family or those around you aware of your intention to pursue this goal. You must then discipline yourself to keep on track until changing circumstances mean you have to revisit the start of the decision making process.

However, there are things that get in the way of simple decision making. We all carry with us a range of likes and dislikes, learnt behaviours and personal preferences developed throughout our lives; they are the hallmarks of being human. A major contribution to ensuring we think critically is to be aware of these personal characteristics, preferences and biases and make allowance for them when considering possible next steps, whether they are at the pre-action consideration stage or as part of a rethink caused by unexpected or unforeseen impediments to continued progress.

The more clearly we are aware of ourselves, our strengths and weaknesses, the more likely our critical thinking will be productive.

The Benefit of Foresight

Perhaps the most important element of thinking critically is foresight.

Almost all decisions we make and implement don’t prove disastrous if we find reasons to abandon them. However, our decision making will be infinitely better and more likely to lead to success if, when we reach a tentative conclusion, we pause and consider the impact on the people and activities around us.

The elements needing consideration are generally numerous and varied. In many cases, consideration of one element from a different perspective will reveal potential dangers in pursuing our decision.

For instance, moving a business activity to a new location may improve potential output considerably but it may also lead to the loss of skilled workers if the distance moved is too great. Which of these is the more important consideration? Is there some way of lessening the conflict?

These are the sort of problems that may arise from incomplete critical thinking, a demonstration perhaps of the critical importance of good critical thinking.

In Summary:

Critical thinking is aimed at achieving the best possible outcomes in any situation. In order to achieve this it must involve gathering and evaluating information from as many different sources possible.

Critical thinking requires a clear, often uncomfortable, assessment of your personal strengths, weaknesses and preferences and their possible impact on decisions you may make.

Critical thinking requires the development and use of foresight as far as this is possible. As Doris Day sang, “the future’s not ours to see”.

Implementing the decisions made arising from critical thinking must take into account an assessment of possible outcomes and ways of avoiding potentially negative outcomes, or at least lessening their impact.

• Critical thinking involves reviewing the results of the application of decisions made and implementing change where possible.

It might be thought that we are overextending our demands on critical thinking in expecting that it can help to construct focused meaning rather than examining the information given and the knowledge we have acquired to see if we can, if necessary, construct a meaning that will be acceptable and useful.

After all, almost no information we have available to us, either externally or internally, carries any guarantee of its life or appropriateness.  Neat step-by-step instructions may provide some sort of trellis on which our basic understanding of critical thinking can blossom but it doesn’t and cannot provide any assurance of certainty, utility or longevity.

Bertrand Russell’s 10 Essential Rules Of Critical Thinking

Bertrand Russell’s essential rules of critical thinking: #1. Do not feel absolutely certain of anything.

By Terry Heick

For a field of study that explores the nature of knowledge, Philosophy has had a surprisingly small impact on education.

Most formal academic ‘platforms’ like public schools and universities tend to parse knowledge into content areas–what is being learned–rather than how and why it is being learned. This, to a degree, reduces the function of pure philosophy. Psychology, Neurology, and even Anthropology all have had a louder voice in ‘education,’ which may explain why critical thinking seems to be so often missing from most school and curriculum design.

There are exceptions, of course. John Dewey is one of the central figures in modern Western education. British philosopher  Bertrand Russell , too, was interested in how people think and learn, and for a 1951 piece in New York Times Magazine created a convenient itemized list we might follow as a kind of set of ‘rules’ for for critical thinking (he called them ‘commandments’–long story).

Perhaps the essence of the Liberal outlook could be summed up in a new decalogue, not intended to replace the old one but only to supplement it. The Ten Commandments that, as a teacher, I should wish to promulgate, might be set forth as follows:

• Do not feel absolutely certain of anything.
• Do not think it worth while to proceed by concealing evidence, for the evidence is sure to come to light.
• Never try to discourage thinking for you are sure to succeed.
• When you meet with opposition, even if it should be from your husband or your children, endeavor to overcome it by argument and not by authority, for a victory dependent upon authority is unreal and illusory.
• Have no respect for the authority of others, for there are always contrary authorities to be found.
• Do not use power to suppress opinions you think pernicious, for if you do the opinions will suppress you.
• Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.
• Find more pleasure in intelligent dissent than in passive agreement, for, if you value intelligence as you should, the former implies a deeper agreement than the latter.
• Be scrupulously truthful, even if the truth is inconvenient, for it is more inconvenient when you try to conceal it.
• Do not feel envious of the happiness of those who live in a fool’s paradise, for only a fool will think that it is happiness.

Critical Thinking and Decision-Making: What is Critical Thinking?

Lesson 1: what is critical thinking, what is critical thinking.

Critical thinking is a term that gets thrown around a lot. You've probably heard it used often throughout the years whether it was in school, at work, or in everyday conversation. But when you stop to think about it, what exactly is critical thinking and how do you do it ?

Watch the video below to learn more about critical thinking.

Simply put, critical thinking is the act of deliberately analyzing information so that you can make better judgements and decisions . It involves using things like logic, reasoning, and creativity, to draw conclusions and generally understand things better.

This may sound like a pretty broad definition, and that's because critical thinking is a broad skill that can be applied to so many different situations. You can use it to prepare for a job interview, manage your time better, make decisions about purchasing things, and so much more.

The process

As humans, we are constantly thinking . It's something we can't turn off. But not all of it is critical thinking. No one thinks critically 100% of the time... that would be pretty exhausting! Instead, it's an intentional process , something that we consciously use when we're presented with difficult problems or important decisions.

Improving your critical thinking

In order to become a better critical thinker, it's important to ask questions when you're presented with a problem or decision, before jumping to any conclusions. You can start with simple ones like What do I currently know? and How do I know this? These can help to give you a better idea of what you're working with and, in some cases, simplify more complex issues.  

Real-world applications

Let's take a look at how we can use critical thinking to evaluate online information . Say a friend of yours posts a news article on social media and you're drawn to its headline. If you were to use your everyday automatic thinking, you might accept it as fact and move on. But if you were thinking critically, you would first analyze the available information and ask some questions :

• What's the source of this article?
• Is the headline potentially misleading?
• What are my friend's general beliefs?
• Do their beliefs inform why they might have shared this?

After analyzing all of this information, you can draw a conclusion about whether or not you think the article is trustworthy.

Critical thinking has a wide range of real-world applications . It can help you to make better decisions, become more hireable, and generally better understand the world around you.

3 critical thinking strategies to enhance your problem-solving skills

Think back to the last time you made a big decision.

Maybe you were choosing between two jobs or whether to move across the country.

How did you make your choice? Most likely, you analyzed the pros and cons of each option and chose the one that made the most sense for you.

This decision-making process relied on an important skill we all need: critical thinking.

Critical thinking is usually associated with analyzing complex problems in a corporate boardroom or sitting through a tedious philosophy lecture. While those are undoubtedly valid applications of critical thinking skills, the truth is that everyone thinks critically every day — often without even realizing it.

Critical thinking strategies allow us to objectively evaluate information and make informed decisions based on logic and reason. The critical thinking process is essential for success in many areas, from business to academia to parenting. No matter your profession or lifestyle, learning how to think critically can improve your life in countless ways.

In this article, you'll learn more about critical thinking skills and how to enhance them by following specific, actionable critical thinking strategies.

What is critical thinking?

There are many ways to interpret the concept of critical thinking. Science, academia, and business all have their own viewpoints. An official definition of critical thinking is difficult to label, and that's logical. After all, the critical thinking process isn't about memorizing generic definitions — it's about asking questions for yourself.

At its simplest, the Foundation for Critical Thinking (FCT) Model defines critical thinking as "...the art of analyzing and evaluating thinking with a view to improving it." The critical thinking process is about being objective — seeing different points of view and keeping an open mind when new information contradicts your beliefs and opinions. Critical thinkers prioritize facts over emotions, remove biases, verify information, and use logical reasoning to solve problems.

When is a critical thinking strategy essential?

Sound reasoning is essential to making good decisions. Since we all make thousands of decisions every day, it can be beneficial to strengthen our reasoning and problem-solving skills.

However, critical thinking skills can be more than just helpful in some situations — they're vital. These instances include:

• Interpreting the news . Social networking has changed the way we receive information. About half of U.S. adults get their news from social media , and more than a third regularly turn to Facebook as their source. Since anyone can share anything on social networks, fake news spreads quickly , so it's essential to think critically to discern fake news from accurate reporting.
• In the workplace . According to the World Economic Forum, critical thinking skills are one of the top two skills needed for the future of work as the Fourth Industrial Revolution develops). Indeed, 93% of executives say "a candidate's demonstrated capacity to think critically, communicate clearly, and solve complex problems is more important than their undergraduate major."
• Formal education and self-learning . Critical thinking skills help learners engage in the learning process. Thinking critically encourages curiosity, leading us to ask tough questions when faced with challenging situations or material and delve deeper into the new subject matter. As a result, we better understand the information and discover practical ways to integrate it.
• Parenting . Parenting involves various critical thinking skills, from managing discipline to making care decisions. A constant stream of opinions and trends on social media makes decision-making even more challenging for a modern parent. Asking open-ended questions, researching claims, becoming aware of critical thinking barriers , and being skeptical of trends are necessary to make informed decisions about children's care.

These are just a few examples of situations where critical thinking can be helpful. There are many other areas of life in which critical thinking strategies are beneficial. To use them properly, you'll need to develop a few key critical thinking skills.

Critical thinking skills

Applying critical thinking strategies requires the use of a few essential skills. Experts identify the core critical thinking skills as:

• Interpretation is the ability to understand and make sense of information. When we interpret something, we use subskills like categorization and significance to help us clarify the meaning.
• Analysis refers to breaking down complex ideas and concepts into smaller chunks that can be better understood. This skill requires effectively examining ideas to identify the critical components or problems.
• Evaluation is the ability to determine whether or not a particular claim or piece of evidence is valid and credible. Subskills like logic and reasoning help us judge the quality or value of something.
• Inference is the process of drawing logical conclusions from the presented information. This skill helps critical thinkers understand new ideas by looking for patterns and connections between different pieces of information.
• Explanation refers to effectively communicating in a way that others can easily understand. This entails simplifying complex information to present the findings of your reasoning in a clear way with well-reasoned arguments that look at the big picture.
• Self-regulation is the ability to monitor your own thinking and behavior to improve performance over time. This skill allows critical thinkers to reflect on their progress and make adjustments to achieve better results.

Developing these skills will lead to better critical thinking. Skill development can occur in a wide variety of situations by practicing specific strategies.

3 critical thinking strategies to try

Developing and refining critical thinking skills takes time and practice. If you want to sharpen your problem-solving skills, here are a few critical thinking strategies you can use as a starting point.

Strategy 1: Comprehensive Analysis

A critical approach to any argument should begin with a detailed and systematic examination. When you break down the claim into elements, you can evaluate each segment separately to determine its legitimacy.

Start by analyzing the language of the argument. Analyze the following factors:

• Make sure that words are used in the correct context by checking their meaning
• The definition of words within the context of the argument should be accurate
• Make sure the language being used has clarity and makes sense
• Verify the accuracy of the language in the statement to ensure it is fair and factual

Evaluating an argument's words and phrases is an essential first step to determining validity.

The next step is to examine the claim's structure. There is a basic structure to all arguments — one or more premises lead to a conclusion. The premise is the statement(s) that provides evidence supporting the conclusion. The conclusion is the claim that is made in the argument, usually highlighted by words like "so" or "therefore." Understanding this basic structure is essential to identify each piece for assessment.

Standardization

Consider standardizing the argument if necessary. A few situations may require restructuring into a standard structure. When a statement isn't logically arranged, extracting premises and conclusions and rearranging them make them easier to comprehend.

When more than one premise exists for a single conclusion, making two separate assertions with the conclusion makes it easier to assess each assumption separately.

Sometimes, an argument is missing its conclusion because the author implied it. It's often easier to understand an implied conclusion when the structure is broken down into a standardized format. In the same way, a missing premise can occur when part of the element is common knowledge or assumed.

Classification

As a final step, classify the argument. All arguments are either deductive or non-deductive. The strategies you will use to evaluate your argument will vary depending on whether your argument is deductive. Deductive arguments contain premises that guarantee their conclusions. The premises of non-deductive arguments cannot guarantee the truth of their findings.

Strategy 2: Utilize Bloom's Taxonomy

Another strategy that can develop the critical thinking process is Bloom's Taxonomy . Educators worldwide have used the framework created by Benjamin Bloom to define and distinguish different levels of human cognition, like reasoning, learning, and comprehension.

In the original model, there were six main categories:

• Comprehension
• Application

In 2001, researchers, educators, and psychologists revised the taxonomy to reflect a more dynamic approach to education, changing the labels to represent the actions taken at each step of the system:

The six levels are arranged in hierarchical form, moving from the simplest level of cognition — thinking — to the highest, most complex level — evaluation.

Bloom's Taxonomy can serve as a useful critical thinking strategy in two ways. Teachers can use the taxonomy to promote critical thinking in their teaching strategies. By assessing the cognition level of their students, teachers can plan and deliver instruction at the appropriate level, ensuring that tasks and assessments align with the objective. Most importantly, they can tailor the types of questions they ask in classroom discussion by using strategic words that challenge students on different levels of cognition.

For classroom students and self-learners, the taxonomy provides a structured framework for decision-making. Students are guided through the process of critical analysis, starting with acquiring knowledge. As learners progress through the steps, they are encouraged to gather more information and examine it analytically before evaluating it to reach a decision.

Strategy 3: Apply the Falsification Theory

The Falsification Theory is an approach that aims to separate science from non-science proposed by 20th-century philosopher Karl Popper. In short, it implies that a scientific theory or hypothesis is falsifiable if it can be logically refuted by an empirical test. For example, observing a white duck can falsify the hypothesis that "all ducks are yellow."

It can be helpful to use falsification as a critical thinking strategy when evaluating new information or scientific claims. This encourages us to test our assumptions and seek disconfirming evidence. When we actively seek out information that contradicts our beliefs, we can more accurately assess the validity of our ideas by avoiding narrow thinking and removing bias.

The theory isn't without criticism, however. Skeptics argue that it's too simplistic. Some cite scientific theories (like Einstein's theory of relativity) that haven't been proven false yet are still considered scientific. Other people argue that some theories (such as Darwin's theory of evolution) have been tested and found true yet are still being tested and critiqued.

Whether or not the Falsification Theory is a perfect way of distinguishing science from non-science may be debated. Still, it remains a valuable tool for thinking critically about the information we encounter in everyday life.

Enhance your higher-order thinking skills

Developing higher-order thinking skills and refining the critical thinking process are essential for those who seek personal and professional development. Enhancing your decision-making abilities requires developing essential critical thinking skills and learning how you can apply them.

The three critical thinking strategies shared here are just a sample of the many strategic ways you can use the critical thinking process. Higher-order thinking takes practice, so don't get discouraged if it feels difficult at first. With time and patience, you can become a master critical thinker.

Master the 3 Basics of Critical Thinking

Critical thinking is a whole lot harder than it looks..

Posted March 15, 2023 | Reviewed by Vanessa Lancaster

• Find a Child Therapist
• The best way to build strong mental muscles is the same as building physical muscles: Exercise regularly.
• Often, you don’t need to make important decisions based on your current judgment.
• Good decision-making is about being able to predict likely outcomes.

Critical thinking skills are incredibly valuable–among the most in-demand skills in nearly every labor market sector. They are so valuable and in demand because they are considered to be in relatively short supply. That’s because critical thinking is a whole lot harder than it looks.

Critical thinkers do not leap to conclusions. Instead, they take the time to consider various possibilities and do not become too attached to one point of view. They do not latch on to one solution. Rather, they know that most solutions are temporary and improve over time with new data. Critical thinkers are in the habit of distinguishing between reliable and unreliable sources. They carefully weigh the strengths of conflicting views and apply logical reasoning. Critical thinkers are, at once, open to the views of others and supremely independent in their judgments.

If you want to set yourself apart at your job or in the hiring process, these are the three elements of critical thinking to master.

1. Proactive Learning

Here’s why you should care about proactive learning: Of course, the more you learn, the more you will know. But there is more to it than that: All the leading research shows that the very act of learning also strengthens your mind. If you are not actively learning, your mind is weakening—just like any muscle. No matter how smart you are, if you are not actively learning, you steadily lose those smarts over time.

The best way to build strong mental muscles is the same as physical ones: exercise them regularly. That means studying information, practicing technique, and contemplating multiple competing perspectives:

• Stored knowledge is the result of studying good information.
• Stored skills are the result of practicing good technique.
• Stored wisdom is the result of contemplating multiple competing good perspectives.

“Good technique,” in the case of non-physical skills, means keeping an open mind. That means suspending judgment, questioning assumptions, and continually seeking the best new information, technique, and perspective.

2. Problem-Solving

In today’s information environment, so many answers to so many questions are available at the tip of their fingers. Many people today are simply not in the habit of truly thinking on their feet. Without a lot of experience puzzling through problems, it should be no surprise that many people are often puzzled when encountering unanticipated problems.

Here’s the thing: Usually, you don’t need to make important decisions based on your current judgment. You are much better off if you can rely on the accumulated experience of the organization in which you are working.

Ready-made solutions are just best practices captured, turned into standard operating procedures, and deployed throughout the organization to employees for use as job aids. The most common is a simple checklist:

• If A happens, do B
• If C happens, do D
• If E happens, do F

What kind of job aids do you have at your disposal to deal with recurring problems? If you already have such job aids at your disposal, how can you better use them as learning tools?

And here’s the good news: By mastering these best practices, you will get better not only at solving the specific problems anticipated but also much better at solving unanticipated problems. By implementing specific step-by-step solutions to recurring problems, you will learn a lot about good problem-solving.

3. Decision-Making

Decision-making is not the same as sheer brain power, mental capacity, or natural intelligence . It’s not a matter of accumulated knowledge or memorized information. It is more than the mastery of techniques and tools.

Good decision-making is about predicting likely outcomes–the ability to see the connections between cause and effect–to project out the consequences of one set of events and actions instead of another. The irony is that learning from the past is the only way to develop that “go forward” ability to predict the future.

But experience alone does not teach good decision-making. The key to learning from experience is paying close attention and aggressively drawing lessons from one’s experiences. If you can begin to see the patterns in causes and their effects, you can start thinking ahead with insight. Ultimately, that’s the key to better decision-making.

What Is Critical Thinking? | Definition & Examples

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Table of contents

Why is critical thinking important, critical thinking examples, how to think critically, other interesting articles, frequently asked questions about critical thinking.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

Defining Critical Thinking

CriticalThinking.NET

thinking in practice

What is critical thinking?

How can we define critical thinking? 

Critical thinking is reasonable reflective thinking focused on deciding what to believe or do. 

A brief conception is below. For a longer definition, please see  long definition . A BRIEF CONCEPTION OF CRITICAL THINKING A critical thinker: 1. Is  open-minded  and mindful of  alternatives 2. Desires to be, and is,  well-informed 3. Judges well the  credibility of sources 4. Identifies  reasons ,  assumptions , and  conclusions 5. Asks appropriate  clarifying questions 6. Judges well the  quality of an argument , including its  reasons ,  assumptions ,  evidence , and their  degree of support for the conclusion 7. Can well  develop and  defend a reasonable position  regarding a belief or an action, doing justice to challenges 8.  Formulates plausible hypotheses 9. Plans and conducts  experiments  well 10.  Defines terms  in a way appropriate for the context 11.  Draws conclusions  when warranted – but with caution 12.  Integrates  all of the above aspects of critical thinking  Last revised 11/26/10 

(Note that this conception of critical thinking is not negative. It is also not mere persuasion, though critical thought will often be persuasive — but perhaps not often enough – the challenge of this century.)

I reviewed this book for a course titled "Creative and Critical Inquiry into Modern Life." It won't meet all my needs for that course, but I haven't yet found a book that would. I wanted to review this one because it states in the preface that it fits better for a general critical thinking course than for a true logic course. I'm not sure that I'd agree. I have been using Browne and Keeley's "Asking the Right Questions: A Guide to Critical Thinking," and I think that book is a better introduction to critical thinking for non-philosophy majors. However, the latter is not open source so I will figure out how to get by without it in the future. Overall, the book seems comprehensive if the subject is logic. The index is on the short-side, but fine. However, one issue for me is that there are no page numbers on the table of contents, which is pretty annoying if you want to locate particular sections.

Content Accuracy rating: 4

I didn't find any errors. In general the book uses great examples. However, they are very much based in the American context, not for an international student audience. Some effort to broaden the chosen examples would make the book more widely applicable.

Relevance/Longevity rating: 4

I think the book will remain relevant because of the nature of the material that it addresses, however there will be a need to modify the examples in future editions and as the social and political context changes.

Clarity rating: 3

The text is lucid, but I think it would be difficult for introductory-level students who are not philosophy majors. For example, in Browne and Keeley's "Asking the Right Questions: A Guide to Critical Thinking," the sub-headings are very accessible, such as "Experts cannot rescue us, despite what they say" or "wishful thinking: perhaps the biggest single speed bump on the road to critical thinking." By contrast, Van Cleave's "Introduction to Logic and Critical Thinking" has more subheadings like this: "Using your own paraphrases of premises and conclusions to reconstruct arguments in standard form" or "Propositional logic and the four basic truth functional connectives." If students are prepared very well for the subject, it would work fine, but for students who are newly being introduced to critical thinking, it is rather technical.

It seems to be very consistent in terms of its terminology and framework.

Modularity rating: 4

The book is divided into 4 chapters, each having many sub-chapters. In that sense, it is readily divisible and modular. However, as noted above, there are no page numbers on the table of contents, which would make assigning certain parts rather frustrating. Also, I'm not sure why the book is only four chapter and has so many subheadings (for instance 17 in Chapter 2) and a length of 242 pages. Wouldn't it make more sense to break up the book into shorter chapters? I think this would make it easier to read and to assign in specific blocks to students.

Organization/Structure/Flow rating: 4

The organization of the book is fine overall, although I think adding page numbers to the table of contents and breaking it up into more separate chapters would help it to be more easily navigable.

Interface rating: 4

The book is very simply presented. In my opinion it is actually too simple. There are few boxes or diagrams that highlight and explain important points.

The text seems fine grammatically. I didn't notice any errors.

The book is written with an American audience in mind, but I did not notice culturally insensitive or offensive parts.

Overall, this book is not for my course, but I think it could work well in a philosophy course.

This textbook is not particularly comprehensive (4 chapters long), but I view that as a benefit. In fact, I recommend it for use outside of traditional logic classes, but rather interdisciplinary classes that evaluate argument

To the best of my ability, I regard this content as accurate, error-free, and unbiased

The book is broadly relevant and up-to-date, with a few stray temporal references (sydney olympics, particular presidencies). I don't view these time-dated examples as problematic as the logical underpinnings are still there and easily assessed

Clarity rating: 4

My only pushback on clarity is I didn't find the distinction between argument and explanation particularly helpful/useful/easy to follow. However, this experience may have been unique to my class.

To the best of my ability, I regard this content as internally consistent

I found this text quite modular, and was easily able to integrate other texts into my lessons and disregard certain chapters or sub-sections

The book had a logical and consistent structure, but to the extent that there are only 4 chapters, there isn't much scope for alternative approaches here

No problems with the book's interface

The text is grammatically sound

Cultural Relevance rating: 4

Perhaps the text could have been more universal in its approach. While I didn't find the book insensitive per-se, logic can be tricky here because the point is to evaluate meaningful (non-trivial) arguments, but any argument with that sense of gravity can also be traumatic to students (abortion, death penalty, etc)

The text covers all the relevant technical aspects of introductory logic and critical thinking, and covers them well. A separate glossary would be quite helpful to students. However, the terms are clearly and thoroughly explained within the text, and the index is very thorough.

The content is excellent. The text is thorough and accurate with no errors that I could discern. The terminology and exercises cover the material nicely and without bias.

The text should easily stand the test of time. The exercises are excellent and would be very helpful for students to internalize correct critical thinking practices. Because of the logical arrangement of the text and the many sub-sections, additional material should be very easy to add.

The text is extremely clearly and simply written. I anticipate that a diligent student could learn all of the material in the text with little additional instruction. The examples are relevant and easy to follow.

The text did not confuse terms or use inconsistent terminology, which is very important in a logic text. The discipline often uses multiple terms for the same concept, but this text avoids that trap nicely.

The text is fairly easily divisible. Since there are only four chapters, those chapters include large blocks of information. However, the chapters themselves are very well delineated and could be easily broken up so that parts could be left out or covered in a different order from the text.

The flow of the text is excellent. All of the information is handled solidly in an order that allows the student to build on the information previously covered.

The PDF Table of Contents does not include links or page numbers which would be very helpful for navigation. Other than that, the text was very easy to navigate. All the images, charts, and graphs were very clear

The text including examples and exercises did not seem to be offensive or insensitive in any specific way. However, the examples included references to black and white people, but few others. Also, the text is very American specific with many examples from and for an American audience. More diversity, especially in the examples, would be appropriate and appreciated.

This is an excellent introductory (first-year) Logic and Critical Thinking textbook. The book covers the important elementary information, clearly discussing such things as the purpose and basic structure of an argument; the difference between an argument and an explanation; validity; soundness; and the distinctions between an inductive and a deductive argument in accessible terms in the first chapter. It also does a good job introducing and discussing informal fallacies (Chapter 4). The incorporation of opportunities to evaluate real-world arguments is also very effective. Chapter 2 also covers a number of formal methods of evaluating arguments, such as Venn Diagrams and Propositional logic and the four basic truth functional connectives, but to my mind, it is much more thorough in its treatment of Informal Logic and Critical Thinking skills, than it is of formal logic. I also appreciated that Van Cleave’s book includes exercises with answers and an index, but there is no glossary; which I personally do not find detracts from the book's comprehensiveness.

Overall, Van Cleave's book is error-free and unbiased. The language used is accessible and engaging. There were no glaring inaccuracies that I was able to detect.

Van Cleave's Textbook uses relevant, contemporary content that will stand the test of time, at least for the next few years. Although some examples use certain subjects like former President Obama, it does so in a useful manner that inspires the use of critical thinking skills. There are an abundance of examples that inspire students to look at issues from many different political viewpoints, challenging students to practice evaluating arguments, and identifying fallacies. Many of these exercises encourage students to critique issues, and recognize their own inherent reader-biases and challenge their own beliefs--hallmarks of critical thinking.

As mentioned previously, the author has an accessible style that makes the content relatively easy to read and engaging. He also does a suitable job explaining jargon/technical language that is introduced in the textbook.

Van Cleave uses terminology consistently and the chapters flow well. The textbook orients the reader by offering effective introductions to new material, step-by-step explanations of the material, as well as offering clear summaries of each lesson.

This textbook's modularity is really quite good. Its language and structure are not overly convoluted or too-lengthy, making it convenient for individual instructors to adapt the materials to suit their methodological preferences.

The topics in the textbook are presented in a logical and clear fashion. The structure of the chapters are such that it is not necessary to have to follow the chapters in their sequential order, and coverage of material can be adapted to individual instructor's preferences.

The textbook is free of any problematic interface issues. Topics, sections and specific content are accessible and easy to navigate. Overall it is user-friendly.

I did not find any significant grammatical issues with the textbook.

The textbook is not culturally insensitive, making use of a diversity of inclusive examples. Materials are especially effective for first-year critical thinking/logic students.

I intend to adopt Van Cleave's textbook for a Critical Thinking class I am teaching at the Community College level. I believe that it will help me facilitate student-learning, and will be a good resource to build additional classroom activities from the materials it provides.

While the book is admirably comprehensive, its extensive details within a few short chapters may feel overwhelming to students. The author tackles an impressive breadth of concepts in Chapter 1, 2, 3, and 4, which leads to 50-plus-page chapters that are dense with statistical analyses and critical vocabulary. These topics are likely better broached in manageable snippets rather than hefty single chapters.

The ideas addressed in Introduction to Logic and Critical Thinking are accurate but at times notably political. While politics are effectively used to exemplify key concepts, some students may be distracted by distinct political leanings.

The terms and definitions included are relevant, but the examples are specific to the current political, cultural, and social climates, which could make the materials seem dated in a few years without intentional and consistent updates.

While the reasoning is accurate, the author tends to complicate rather than simplify -- perhaps in an effort to cover a spectrum of related concepts. Beginning readers are likely to be overwhelmed and under-encouraged by his approach.

Consistency rating: 3

The four chapters are somewhat consistent in their play of definition, explanation, and example, but the structure of each chapter varies according to the concepts covered. In the third chapter, for example, key ideas are divided into sub-topics numbering from 3.1 to 3.10. In the fourth chapter, the sub-divisions are further divided into sub-sections numbered 4.1.1-4.1.5, 4.2.1-4.2.2, and 4.3.1 to 4.3.6. Readers who are working quickly to master new concepts may find themselves mired in similarly numbered subheadings, longing for a grounded concepts on which to hinge other key principles.

Modularity rating: 3

The book's four chapters make it mostly self-referential. The author would do well to beak this text down into additional subsections, easing readers' accessibility.

The content of the book flows logically and well, but the information needs to be better sub-divided within each larger chapter, easing the student experience.

The book's interface is effective, allowing readers to move from one section to the next with a single click. Additional sub-sections would ease this interplay even further.

Grammatical Errors rating: 4

Some minor errors throughout.

For the most part, the book is culturally neutral, avoiding direct cultural references in an effort to remain relevant.

This textbook covers enough topics for a first-year course on logic and critical thinking. Chapter 1 covers the basics as in any standard textbook in this area. Chapter 2 covers propositional logic and categorical logic. In propositional logic, this textbook does not cover suppositional arguments, such as conditional proof and reductio ad absurdum. But other standard argument forms are covered. Chapter 3 covers inductive logic, and here this textbook introduces probability and its relationship with cognitive biases, which are rarely discussed in other textbooks. Chapter 4 introduces common informal fallacies. The answers to all the exercises are given at the end. However, the last set of exercises is in Chapter 3, Section 5. There are no exercises in the rest of the chapter. Chapter 4 has no exercises either. There is index, but no glossary.

The textbook is accurate.

The content of this textbook will not become obsolete soon.

The textbook is written clearly.

The textbook is internally consistent.

The textbook is fairly modular. For example, Chapter 3, together with a few sections from Chapter 1, can be used as a short introduction to inductive logic.

The textbook is well-organized.

There are no interface issues.

This text is a beginner textbook for arguments and propositional logic. It covers the basics of identifying arguments, building arguments, and using basic logic to construct propositions and arguments. It is quite comprehensive for a beginner book, but seems to be a good text for a course that needs a foundation for arguments. There are exercises on creating truth tables and proofs, so it could work as a logic primer in short sessions or with the addition of other course content.

The books is accurate in the information it presents. It does not contain errors and is unbiased. It covers the essential vocabulary clearly and givens ample examples and exercises to ensure the student understands the concepts

The content of the book is up to date and can be easily updated. Some examples are very current for analyzing the argument structure in a speech, but for this sort of text understandable examples are important and the author uses good examples.

The book is clear and easy to read. In particular, this is a good text for community college students who often have difficulty with reading comprehension. The language is straightforward and concepts are well explained.

The book is consistent in terminology, formatting, and examples. It flows well from one topic to the next, but it is also possible to jump around the text without loosing the voice of the text.

The books is broken down into sub units that make it easy to assign short blocks of content at a time. Later in the text, it does refer to a few concepts that appear early in that text, but these are all basic concepts that must be used to create a clear and understandable text. No sections are too long and each section stays on topic and relates the topic to those that have come before when necessary.

The flow of the text is logical and clear. It begins with the basic building blocks of arguments, and practice identifying more and more complex arguments is offered. Each chapter builds up from the previous chapter in introducing propositional logic, truth tables, and logical arguments. A select number of fallacies are presented at the end of the text, but these are related to topics that were presented before, so it makes sense to have these last.

The text is free if interface issues. I used the PDF and it worked fine on various devices without loosing formatting.

1. The book contains no grammatical errors.

The text is culturally sensitive, but examples used are a bit odd and may be objectionable to some students. For instance, President Obama's speech on Syria is used to evaluate an extended argument. This is an excellent example and it is explained well, but some who disagree with Obama's policies may have trouble moving beyond their own politics. However, other examples look at issues from all political viewpoints and ask students to evaluate the argument, fallacy, etc. and work towards looking past their own beliefs. Overall this book does use a variety of examples that most students can understand and evaluate.

My favorite part of this book is that it seems to be written for community college students. My students have trouble understanding readings in the New York Times, so it is nice to see a logic and critical thinking text use real language that students can understand and follow without the constant need of a dictionary.

This textbook is quite thorough--there are conversational explanations of argument structure and logic. I think students will be happy with the conversational style this author employs. Also, there are many examples and exercises using current events, funny scenarios, or other interesting ways to evaluate argument structure and validity. The third section, which deals with logical fallacies, is very clear and comprehensive. My only critique of the material included in the book is that the middle section may be a bit dense and math-oriented for learners who appreciate the more informal, informative style of the first and third section. Also, the book ends rather abruptly--it moves from a description of a logical fallacy to the answers for the exercises earlier in the text.

The content is very reader-friendly, and the author writes with authority and clarity throughout the text. There are a few surface-level typos (Starbuck's instead of Starbucks, etc.). None of these small errors detract from the quality of the content, though.

One thing I really liked about this text was the author's wide variety of examples. To demonstrate different facets of logic, he used examples from current media, movies, literature, and many other concepts that students would recognize from their daily lives. The exercises in this text also included these types of pop-culture references, and I think students will enjoy the familiarity--as well as being able to see the logical structures behind these types of references. I don't think the text will need to be updated to reflect new instances and occurrences; the author did a fine job at picking examples that are relatively timeless. As far as the subject matter itself, I don't think it will become obsolete any time soon.

The author writes in a very conversational, easy-to-read manner. The examples used are quite helpful. The third section on logical fallacies is quite easy to read, follow, and understand. A student in an argument writing class could benefit from this section of the book. The middle section is less clear, though. A student learning about the basics of logic might have a hard time digesting all of the information contained in chapter two. This material might be better in two separate chapters. I think the author loses the balance of a conversational, helpful tone and focuses too heavily on equations.

Consistency rating: 4

Terminology in this book is quite consistent--the key words are highlighted in bold. Chapters 1 and 3 follow a similar organizational pattern, but chapter 2 is where the material becomes more dense and equation-heavy. I also would have liked a closing passage--something to indicate to the reader that we've reached the end of the chapter as well as the book.

I liked the overall structure of this book. If I'm teaching an argumentative writing class, I could easily point the students to the chapters where they can identify and practice identifying fallacies, for instance. The opening chapter is clear in defining the necessary terms, and it gives the students an understanding of the toolbox available to them in assessing and evaluating arguments. Even though I found the middle section to be dense, smaller portions could be assigned.

The author does a fine job connecting each defined term to the next. He provides examples of how each defined term works in a sentence or in an argument, and then he provides practice activities for students to try. The answers for each question are listed in the final pages of the book. The middle section feels like the heaviest part of the whole book--it would take the longest time for a student to digest if assigned the whole chapter. Even though this middle section is a bit heavy, it does fit the overall structure and flow of the book. New material builds on previous chapters and sub-chapters. It ends abruptly--I didn't realize that it had ended, and all of a sudden I found myself in the answer section for those earlier exercises.

The simple layout is quite helpful! There is nothing distracting, image-wise, in this text. The table of contents is clearly arranged, and each topic is easy to find.

Tiny edits could be made (Starbuck's/Starbucks, for one). Otherwise, it is free of distracting grammatical errors.

This text is quite culturally relevant. For instance, there is one example that mentions the rumors of Barack Obama's birthplace as somewhere other than the United States. This example is used to explain how to analyze an argument for validity. The more "sensational" examples (like the Obama one above) are helpful in showing argument structure, and they can also help students see how rumors like this might gain traction--as well as help to show students how to debunk them with their newfound understanding of argument and logic.

The writing style is excellent for the subject matter, especially in the third section explaining logical fallacies. Thank you for the opportunity to read and review this text!

This is a review of Introduction to Logic and Critical Thinking, an open source book version 1.4 by Matthew Van Cleave. The comparison book used was Patrick J. Hurley’s A Concise Introduction to Logic 12th Edition published by Cengage as well as the 13th edition with the same title. Lori Watson is the second author on the 13th edition.

Competing with Hurley is difficult with respect to comprehensiveness. For example, Van Cleave’s book is comprehensive to the extent that it probably covers at least two-thirds or more of what is dealt with in most introductory, one-semester logic courses. Van Cleave’s chapter 1 provides an overview of argumentation including discerning non-arguments from arguments, premises versus conclusions, deductive from inductive arguments, validity, soundness and more. Much of Van Cleave’s chapter 1 parallel’s Hurley’s chapter 1. Hurley’s chapter 3 regarding informal fallacies is comprehensive while Van Cleave’s chapter 4 on this topic is less extensive. Categorical propositions are a topic in Van Cleave’s chapter 2; Hurley’s chapters 4 and 5 provide more instruction on this, however. Propositional logic is another topic in Van Cleave’s chapter 2; Hurley’s chapters 6 and 7 provide more information on this, though. Van Cleave did discuss messy issues of language meaning briefly in his chapter 1; that is the topic of Hurley’s chapter 2.

Van Cleave’s book includes exercises with answers and an index. A glossary was not included.

Reviews of open source textbooks typically include criteria besides comprehensiveness. These include comments on accuracy of the information, whether the book will become obsolete soon, jargon-free clarity to the extent that is possible, organization, navigation ease, freedom from grammar errors and cultural relevance; Van Cleave’s book is fine in all of these areas. Further criteria for open source books includes modularity and consistency of terminology. Modularity is defined as including blocks of learning material that are easy to assign to students. Hurley’s book has a greater degree of modularity than Van Cleave’s textbook. The prose Van Cleave used is consistent.

About the book.

This is an introductory textbook in logic and critical thinking. The goal of the textbook is to provide the reader with a set of tools and skills that will enable them to identify and evaluate arguments. The book is intended for an introductory course that covers both formal and informal logic. As such, it is not a formal logic textbook, but is closer to what one would find marketed as a “critical thinking textbook.”

13 Easy Steps To Improve Your Critical Thinking Skills

• Share to Facebook
• Share to Twitter
• Share to Linkedin

With the sheer volume of information that we’re bombarded with on a daily basis – and with the pervasiveness of fake news and social media bubbles – the ability to look at evidence, evaluate the trustworthiness of a source, and think critically is becoming more important than ever. This is why, for me, critical thinking is one of the most vital skills to cultivate for future success.

Critical thinking isn’t about being constantly negative or critical of everything. It’s about objectivity and having an open, inquisitive mind. To think critically is to analyze issues based on hard evidence (as opposed to personal opinions, biases, etc.) in order to build a thorough understanding of what’s really going on. And from this place of thorough understanding, you can make better decisions and solve problems more effectively.

To put it another way, critical thinking means arriving at your own carefully considered conclusions instead of taking information at face value. Here are 13 ways you can cultivate this precious skill:

1. Always vet new information with a cautious eye. Whether it’s an article someone has shared online or data that’s related to your job, always vet the information you're presented with. Good questions to ask here include, "Is this information complete and up to date?” “What evidence is being presented to support the argument?” and “Whose voice is missing here?”

2. Look at where the information has come from. Is the source trustworthy? What is their motivation for presenting this information? For example, are they trying to sell you something or get you to take a certain action (like vote for them)?

3. Consider more than one point of view. Everyone has their own opinions and motivations – even highly intelligent people making reasonable-sounding arguments have personal opinions and biases that shape their thinking. So, when someone presents you with information, consider whether there are other sides to the story.

4. Practice active listening. Listen carefully to what others are telling you, and try to build a clear picture of their perspective. Empathy is a really useful skill here since putting yourself in another person's shoes can help you understand where they're coming from and what they might want. Try to listen without judgment – remember, critical thinking is about keeping an open mind.

5. Gather additional information where needed. Whenever you identify gaps in the information or data, do your own research to fill those gaps. The next few steps will help you do this objectively…

6. Ask lots of open-ended questions. Curiosity is a key trait of critical thinkers, so channel your inner child and ask lots of "who," "what," and "why" questions.

7. Find your own reputable sources of information, such as established news sites, nonprofit organizations, and education institutes. Try to avoid anonymous sources or sources with an ax to grind or a product to sell. Also, be sure to check when the information was published. An older source may be unintentionally offering up wrong information just because events have moved on since it was published; corroborate the info with a more recent source.

8. Try not to get your news from social media. And if you do see something on social media that grabs your interest, check the accuracy of the story (via reputable sources of information, as above) before you share it.

9. Learn to spot fake news. It's not always easy to spot false or misleading content, but a good rule of thumb is to look at the language, emotion, and tone of the piece. Is it using emotionally charged language, for instance, and trying to get you to feel a certain way? Also, look at the sources of facts, figures, images, and quotes. A legit news story will clearly state its sources.

10. Learn to spot biased information. Like fake news, biased information may seek to appeal more to your emotions than logic and/or present a limited view of the topic. So ask yourself, “Is there more to this topic than what’s being presented here?” Do your own reading around the topic to establish the full picture.

11. Question your own biases, too. Everyone has biases, and there’s no point pretending otherwise. The trick is to think objectively about your likes and dislikes, preferences, and beliefs, and consider how these might affect your thinking.

12. Form your own opinions. Remember, critical thinking is about thinking independently. So once you’ve assessed all the information, form your own conclusions about it.

13. Continue to work on your critical thinking skills. I recommend looking at online learning platforms such as Udemy and Coursera for courses on general critical thinking skills, as well as courses on specific subjects like cognitive biases.

Read more about critical thinking and other essential skills in my new book, Future Skills: The 20 Skills & Competencies Everyone Needs To Succeed In A Digital World . Written for anyone who wants to surf the wave of digital transformation – rather than be drowned by it – the book explores why these vital future skills matter and how to develop them.

How can I tell if what I am hearing is true? – Adam, age 10, Maui, Hawaii

Have you ever heard a story so exciting you wanted to share it right away? Something like a shark swimming up a flooded highway?

An image that seems to show just that was shared by many people after Hurricane Ian struck Florida in 2022. It was also widely shared after Hurricane Harvey hit Houston, Texas, in 2017. It’s a fake – a flooded highway image combined with one of a great white shark. The fact-checking website Snopes found it circulating as far back as 2011 after Hurricane Irene slammed Puerto Rico.

Truth can be tricky to determine. Every message you read, see or hear comes from somewhere and was created by someone and for someone.

I teach media literacy , which is a way to think about information you get in the messages you receive via media . You might think media means the news, but it also includes TikTok posts, television, books, advertisements and more.

When deciding whether to trust a piece of information, it’s good to start with three main questions – who said it, what evidence did they give and how much do you want to believe it? The last one might seem a little strange, but you’ll see why it’s important by the end.

Who said it?

Let’s say you’re really excited about a game that’s coming out later this year. You want to be the first to learn about the new creatures, characters and game modes. So when a YouTube video pops up saying, “GAME COMING TWO WEEKS EARLY,” you can’t wait to watch. But when you click, it’s just a guy making predictions. Do you trust him?

A source is where information comes from. You get information from sources every day – from teachers, parents and friends to people you’ve never met on news sites, fan channels and social media. You probably have sources you trust and ones you don’t. But why?

Would you trust your history teacher to tell you something about history? Probably, because they have a college degree that says they know their stuff. But what if your history teacher told you a fact about science your science teacher said was untrue? You’d probably be better off going with the science teacher for your science facts. Just because a source is trustworthy in one subject doesn’t mean they’re trustworthy in every subject.

Let’s go back to the YouTuber. If you’ve watched him for a while and he’s reliably correct, that’s a good start. At the same time, make sure you don’t confuse his having an opinion with actually having knowledge . Just because you like a source doesn’t make it trustworthy.

This is true for websites, too. When a site grabs your attention, take a second to check the source at the top. Some fake sites use names that sound trustworthy – like “Boston Tribune” instead of “Boston Globe” or “www.cbs.com.co” instead of “www.cbs.com.” You can click the “About” page to see where they’re really coming from, use lists of known fake sites and other fact-checking resources to avoid getting played.

What’s the evidence?

Evidence is what you show when someone says “prove it!” It’s the details that support what a source is saying.

Primary sources – people or groups who are directly involved with the information – are best. If you want to learn about the release of a new game, the company’s official accounts or channels would be primary sources.

Secondary sources are one step removed – for example, news stories based on primary sources. They aren’t as strong as primary sources but are still useful. For example, most news on gaming site IGN is based on information from game company sources, so it’s a good secondary source.

Can a blogger or YouTuber be a secondary source? If their claims start by referencing primary sources like “Electronic Arts says,” that’s good. But if they start with “I think” or “There’s a lot of buzz,” be careful.

Do you want to believe it?

Emotions can get in the way of knowing what’s true. Messages that make you feel strong emotions – especially ones that are funny or make you angry – are the most important ones to check, but they’re also the hardest to ignore .

Advertisers know this. Many ads try to be funny or make the things they’re selling look cool because they want you to focus on how you feel rather than what you think. And being older doesn’t mean you’re automatically better at spotting false information: 41% of 18-to-34-year-olds and 44% of adults 65 and older admitted to having fallen for a fake news story in a 2018 study. Other research showed adults over 65 were seven times as likely to share articles from fake sites as younger people were.

So if you’ve been eagerly waiting for that new game, and somebody posts a video that says it’s coming out early, your wanting it to be true can make you ignore your common sense – leaving you open to being fooled.

The best question you can ask yourself when you’re thinking about a message is, “Do I want to believe this?” If the answer is yes, it’s a good sign you should slow down and check the source and evidence more closely.

Do You Qualify for Spousal Social Security Benefits? 3 Things to Know Before Applying

• Spouses and ex-spouses generally must meet a length-of-marriage requirement before they become eligible for Social Security.
• Your maximum spousal benefit is half your partner's benefit at their full retirement age (FRA).
• The Social Security Administration automatically gives you the larger of your own retirement benefit or your spousal benefit.
• Motley Fool Issues Rare “All In” Buy Alert

Spousal Social Security benefits could be a critical source of retirement income for you, but they're a little more complicated than you might expect.

Spousal Social Security benefits sound pretty straightforward: You marry a qualifying worker, sign up for benefits, and receive monthly checks. This is all true, but it leaves out a few important details that retired couples and those nearing retirement need to know.

Here are three key rules to keep in mind when planning your retirement budget and applying for spousal Social Security benefits.

1. There's a length of marriage requirement

You must be married to your spouse for at least one year before you're eligible for spousal Social Security benefits on their work record. There's an exception to this rule if you qualified for Social Security benefits in the month before the month you got married, or if you're the parent of your spouse's child. Current spouses cannot apply for spousal benefits until their partner is claiming Social Security retirement checks.

Ex-spouses can also qualify for spousal benefits, but they have slightly different requirements. Their marriage to the qualifying worker must have lasted for at least 10 years, unless they are caring for the worker's child who is under 16 or disabled. If there's no qualifying child and the worker isn't claiming Social Security themselves yet, the ex-spouse must wait until they've been divorced for at least two years before applying. Remarriage will render you ineligible to claim on your ex's work record.

2. The most you'll get is half your partner's benefit at their full retirement age (FRA)

The Social Security Administration bases your spousal benefit on the benefit your partner is eligible for at their full retirement age (FRA) . This is 66 to 67, depending on their birth year. They may choose to apply earlier than this, but their decision won't affect the size of your benefit.

When you apply does affect your checks, though. If you wait until your FRA, you'll qualify for your maximum spousal benefit -- one-half of your partner's benefit at their FRA. So if your partner qualifies for $2,000 per month at their FRA, the most you'll get is $1,000 per month.

But you may get less if you apply early. The government reduces your benefit by 25/36 of 1% per month for up to 36 months of early claiming. Those who sign up more than three years early have another 5/12 of 1% withheld from their checks. That means those who apply immediately at 62 could lose as much as 35% from their monthly checks. In our previous example, that would drop your spousal benefit from $1,000 to $650 per month.

3. You might get your own retirement benefit, even if you qualify for a spousal benefit

You only get a spousal Social Security benefit if this amount is less than what you qualify for in your own right. If you didn't work enough to earn a Social Security retirement benefit in the first place, then you'll obviously get a spousal benefit. But it's more complicated for those who are dually eligible for benefits.

You can estimate what your retirement benefit and your spousal benefit could be worth by creating a my Social Security account and using the calculator tools here. For your retirement benefit, you shouldn't have to do anything to figure this out unless you want to change its estimates of your future earnings. To calculate your spousal benefit, you'll need to know how much your spouse qualifies for at their FRA. Once you input this, you'll be able to see your estimated spousal benefit at every age.

If your retirement benefit is higher, you'll get this amount in retirement. If your spousal benefit is higher, you'll get your retirement benefit plus a portion of your spousal benefit. For example, if your retirement benefit was $750 per month and your spousal benefit was $1,000 per month, you'd get your $750 retirement benefit, plus $250 of your spousal benefit for a total monthly check of $1,000.

One last thing to keep in mind if you expect to claim a spousal benefit: Unlike retirement benefits, spousal benefits don't offer you delayed retirement credits for waiting beyond your FRA to apply. So make sure you apply for these benefits no later than your FRA to avoid costing yourself.

If you have any questions about your personal situation, it's best to contact the Social Security Administration directly. They can assist you in figuring out which type of benefit you'll receive and what documents you need to apply.

What Kamala Harris has said so far on key issues in her campaign

As she ramps up her nascent presidential campaign, Vice President Kamala Harris is revealing how she will address the key issues facing the nation.

In speeches and rallies, she has voiced support for continuing many of President Joe Biden’s measures, such as lowering drug costs , forgiving student loan debt and eliminating so-called junk fees. But Harris has made it clear that she has her own views on some key matters, particularly Israel’s treatment of Gazans in its war with Hamas.

In a departure from her presidential run in 2020, the Harris campaign has confirmed that she’s moved away from many of her more progressive stances, such as her interest in a single-payer health insurance system and a ban on fracking.

Harris is also expected to put her own stamp and style on matters ranging from abortion to the economy to immigration, as she aims to walk a fine line of taking credit for the administration’s accomplishments while not being jointly blamed by voters for its shortcomings.

Her early presidential campaign speeches have offered insights into her priorities, though she’s mainly voiced general talking points and has yet to release more nuanced plans. Like Biden, she intends to contrast her vision for America with that of former President Donald Trump. ( See Trump’s campaign promises here .)

“In this moment, I believe we face a choice between two different visions for our nation: one focused on the future, the other focused on the past,” she told members of the historically Black sorority Zeta Phi Beta at an event in Indianapolis in late July. “And with your support, I am fighting for our nation’s future.”

Here’s what we know about Harris’ views:

Harris took on the lead role of championing abortion rights for the administration after Roe v. Wade was overturned in June 2022. This past January, she started a “ reproductive freedoms tour ” to multiple states, including a stop in Minnesota thought to be the first by a sitting US president or vice president at an abortion clinic .

On abortion access, Harris embraced more progressive policies than Biden in the 2020 campaign, as a candidate criticizing his previous support for the Hyde Amendment , a measure that blocks federal funds from being used for most abortions.

Policy experts suggested that although Harris’ current policies on abortion and reproductive rights may not differ significantly from Biden’s, as a result of her national tour and her own focus on maternal health , she may be a stronger messenger.

High prices are a top concern for many Americans who are struggling to afford the cost of living after a spell of steep inflation. Many voters give Biden poor marks for his handling of the economy, and Harris may also face their wrath.

In her early campaign speeches, Harris has echoed many of the same themes as Biden, saying she wants to give Americans more opportunities to get ahead. She’s particularly concerned about making care – health care, child care, elder care and family leave – more affordable and available.

Harris promised at a late July rally to continue the Biden administration’s drive to eliminate so-called “junk fees” and to fully disclose all charges, such as for events, lodging and car rentals. In early August, the administration proposed a rule that would ban airlines from charging parents extra fees to have their kids sit next to them.

On day one, I will take on price gouging and bring down costs. We will ban more of those hidden fees and surprise late charges that banks and other companies use to pad their profits.”

Since becoming vice president, Harris has taken more moderate positions, but a look at her 2020 campaign promises reveals a more progressive bent than Biden.

As a senator and 2020 presidential candidate, Harris proposed providing middle-class and working families with a refundable tax credit of up to $6,000 a year (per couple) to help keep up with living expenses. Titled the LIFT the Middle Class Act, or Livable Incomes for Families Today, the measure would have cost at the time an estimated $3 trillion over 10 years.

Unlike a typical tax credit, the bill would allow taxpayers to receive the benefit – up to $500 – on a monthly basis so families don’t have to turn to payday loans with very high interest rates.

As a presidential candidate, Harris also advocated for raising the corporate income tax rate to 35%, where it was before the 2017 Tax Cuts and Jobs Act that Trump and congressional Republicans pushed through Congress reduced the rate to 21%. That’s higher than the 28% Biden has proposed.

Affordable housing was also on Harris’ radar. As a senator, she introduced the Rent Relief Act, which would establish a refundable tax credit for renters who annually spend more than 30% of their gross income on rent and utilities. The amount of the credit would range from 25% to 100% of the excess rent, depending on the renter’s income.

Harris called housing a human right and said in a 2019 news release on the bill that every American deserves to have basic security and dignity in their own home.

Consumer debt

Hefty debt loads, which weigh on people’s finances and hurt their ability to buy homes, get car loans or start small businesses, are also an area of interest to Harris.

As vice president, she has promoted the Biden administration’s initiatives on student debt, which have so far forgiven more than $168 billion for nearly 4.8 million borrowers . In mid-July, Harris said in a post on X that “nearly 950,000 public servants have benefitted” from student debt forgiveness, compared with only 7,000 when Biden was inaugurated.

A potential Harris administration could keep that momentum going – though some of Biden’s efforts have gotten tangled up in litigation, such as a program aimed at cutting monthly student loan payments for roughly 3 million borrowers enrolled in a repayment plan the administration implemented last year.

The vice president has also been a leader in the White House efforts to ban medical debt from credit reports, noting that those with medical debt are no less likely to repay a loan than those who don’t have unpaid medical bills.

In a late July statement praising North Carolina’s move to relieve the medical debt of about 2 million residents, Harris said that she is “committed to continuing to relieve the burden of medical debt and creating a future where every person has the opportunity to build wealth and thrive.”

Health care

Harris, who has had shifting stances on health care in the past, confirmed in late July through her campaign that she no longer supports a single-payer health care system .

During her 2020 campaign, Harris advocated for shifting the US to a government-backed health insurance system but stopped short of wanting to completely eliminate private insurance.

The measure called for transitioning to a Medicare-for-All-type system over 10 years but continuing to allow private insurance companies to offer Medicare plans.

The proposal would not have raised taxes on the middle class to pay for the coverage expansion. Instead, it would raise the needed funds by taxing Wall Street trades and transactions and changing the taxation of offshore corporate income.

When it comes to reducing drug costs, Harris previously proposed allowing the federal government to set “a fair price” for any drug sold at a cheaper price in any economically comparable country, including Canada, the United Kingdom, France, Japan or Australia. If manufacturers were found to be price gouging, the government could import their drugs from abroad or, in egregious cases, use its existing but never-used “march-in” authority to license a drug company’s patent to a rival that would produce the medication at a lower cost.

Harris has been a champion on climate and environmental justice for decades. As California’s attorney general, Harris sued big oil companies like BP and ConocoPhillips, and investigated Exxon Mobil for its role in climate change disinformation. While in the Senate, she sponsored the Green New Deal resolution.

During her 2020 campaign, she enthusiastically supported a ban on fracking — but a Harris campaign official said in late July that she no longer supports such a ban.

Fracking is the process of using liquid to free natural gas from rock formations – and the primary mode for extracting gas for energy in battleground Pennsylvania. During a September 2019 climate crisis town hall hosted by CNN, she said she would start “with what we can do on Day 1 around public lands.” She walked that back later when she became Biden’s running mate.

Biden has been the most pro-climate president in history, and climate advocates find Harris to be an exciting candidate in her own right. Democrats and climate activists are planning to campaign on the stark contrasts between Harris and Trump , who vowed to push America decisively back to fossil fuels, promising to unwind Biden’s climate and clean energy legacy and pull America out of its global climate commitments.

If elected, one of the biggest climate goals Harris would have to craft early in her administration is how much the US would reduce its climate pollution by 2035 – a requirement of the Paris climate agreement .

Immigration

Harris has quickly started trying to counter Trump’s attacks on her immigration record.

Her campaign released a video in late July citing Harris’ support for increasing the number of Border Patrol agents and Trump’s successful push to scuttle a bipartisan immigration deal that included some of the toughest border security measures in recent memory.

The vice president has changed her position on border control since her 2020 campaign, when she suggested that Democrats needed to “critically examine” the role of Immigration and Customs Enforcement, or ICE, after being asked whether she sided with those in the party arguing to abolish the department.

In June of this year, the White House announced a crackdown on asylum claims meant to continue reducing crossings at the US-Mexico border – a policy that Harris’ campaign manager, Julie Chavez Rodriguez, indicated in late July to CBS News would continue under a Harris administration.

Trump’s attacks stem from Biden having tasked Harris with overseeing diplomatic efforts in Central America in March 2021. While Harris focused on long-term fixes, the Department of Homeland Security remained responsible for overseeing border security.

She has only occasionally talked about her efforts as the situation along the US-Mexico border became a political vulnerability for Biden. But she put her own stamp on the administration’s efforts, engaging the private sector.

Harris pulled together the Partnership for Central America, which has acted as a liaison between companies and the US government. Her team and the partnership are closely coordinating on initiatives that have led to job creation in the region. Harris has also engaged directly with foreign leaders in the region.

Experts credit Harris’ ability to secure private-sector investments as her most visible action in the region to date but have cautioned about the long-term durability of those investments.

Israel-Hamas

The Israel-Hamas war is the most fraught foreign policy issue facing the country and has spurred a multitude of protests around the US since it began in October.

After meeting with Israeli Prime Minister Benjamin Netanyahu in late July, Harris gave a forceful and notable speech about the situation in Gaza.

We cannot look away in the face of these tragedies. We cannot allow ourselves to become numb to the suffering. And I will not be silent.”

Harris echoed Biden’s repeated comments about the “ironclad support” and “unwavering commitment” to Israel. The country has a right to defend itself, she said, while noting, “how it does so, matters.”

However, the empathy she expressed regarding the Palestinian plight and suffering was far more forceful than what Biden has said on the matter in recent months. Harris mentioned twice the “serious concern” she expressed to Netanyahu about the civilian deaths in Gaza, the humanitarian situation and destruction she called “catastrophic” and “devastating.”

She went on to describe “the images of dead children and desperate hungry people fleeing for safety, sometimes displaced for the second, third or fourth time.”

Harris emphasized the need to get the Israeli hostages back from Hamas captivity, naming the eight Israeli-American hostages – three of whom have been killed.

But when describing the ceasefire deal in the works, she didn’t highlight the hostage for prisoner exchange or aid to be let into Gaza. Instead, she singled out the fact that the deal stipulates the withdrawal by the Israeli military from populated areas in the first phase before withdrawing “entirely” from Gaza before “a permanent end to the hostilities.”

Harris didn’t preside over Netanyahu’s speech to Congress in late July, instead choosing to stick with a prescheduled trip to a sorority event in Indiana.

Harris is committed to supporting Ukraine in its fight against Russian aggression, having met with Ukrainian President Volodymyr Zelensky at least six times and announcing last month $1.5 billion for energy assistance, humanitarian needs and other aid for the war-torn country.

At the Munich Security Conference earlier this year, Harris said: “I will make clear President Joe Biden and I stand with Ukraine. In partnership with supportive, bipartisan majorities in both houses of the United States Congress, we will work to secure critical weapons and resources that Ukraine so badly needs. And let me be clear: The failure to do so would be a gift to Vladimir Putin.”

More broadly, NATO is central to our approach to global security. For President Biden and me, our sacred commitment to NATO remains ironclad. And I do believe, as I have said before, NATO is the greatest military alliance the world has ever known.”

Police funding

The Harris campaign has also walked back the “defund the police” sentiment that Harris voiced in 2020. What she meant is she supports being “tough and smart on crime,” Mitch Landrieu, national co-chair for the Harris campaign and former mayor of New Orleans, told CNN’s Pamela Brown in late July.

In the midst of nationwide 2020 protests sparked by George Floyd’s murder by a Minneapolis police officer, Harris voiced support for the “defund the police” movement, which argues for redirecting funds from law enforcement to social services. Throughout that summer, Harris supported the movement and called for demilitarizing police departments.

Democrats largely backed away from calls to defund the police after Republicans attempted to tie the movement to increases in crime during the 2022 midterm elections.

How to cite ChatGPT

We, the APA Style team, are not robots. We can all pass a CAPTCHA test , and we know our roles in a Turing test . And, like so many nonrobot human beings this year, we’ve spent a fair amount of time reading, learning, and thinking about issues related to large language models, artificial intelligence (AI), AI-generated text, and specifically ChatGPT . We’ve also been gathering opinions and feedback about the use and citation of ChatGPT. Thank you to everyone who has contributed and shared ideas, opinions, research, and feedback.

In this post, I discuss situations where students and researchers use ChatGPT to create text and to facilitate their research, not to write the full text of their paper or manuscript. We know instructors have differing opinions about how or even whether students should use ChatGPT, and we’ll be continuing to collect feedback about instructor and student questions. As always, defer to instructor guidelines when writing student papers. For more about guidelines and policies about student and author use of ChatGPT, see the last section of this post.

Quoting or reproducing the text created by ChatGPT in your paper

If you’ve used ChatGPT or other AI tools in your research, describe how you used the tool in your Method section or in a comparable section of your paper. For literature reviews or other types of essays or response or reaction papers, you might describe how you used the tool in your introduction. In your text, provide the prompt you used and then any portion of the relevant text that was generated in response.

Unfortunately, the results of a ChatGPT “chat” are not retrievable by other readers, and although nonretrievable data or quotations in APA Style papers are usually cited as personal communications , with ChatGPT-generated text there is no person communicating. Quoting ChatGPT’s text from a chat session is therefore more like sharing an algorithm’s output; thus, credit the author of the algorithm with a reference list entry and the corresponding in-text citation.

When prompted with “Is the left brain right brain divide real or a metaphor?” the ChatGPT-generated text indicated that although the two brain hemispheres are somewhat specialized, “the notation that people can be characterized as ‘left-brained’ or ‘right-brained’ is considered to be an oversimplification and a popular myth” (OpenAI, 2023).

OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat

You may also put the full text of long responses from ChatGPT in an appendix of your paper or in online supplemental materials, so readers have access to the exact text that was generated. It is particularly important to document the exact text created because ChatGPT will generate a unique response in each chat session, even if given the same prompt. If you create appendices or supplemental materials, remember that each should be called out at least once in the body of your APA Style paper.

When given a follow-up prompt of “What is a more accurate representation?” the ChatGPT-generated text indicated that “different brain regions work together to support various cognitive processes” and “the functional specialization of different regions can change in response to experience and environmental factors” (OpenAI, 2023; see Appendix A for the full transcript).

Creating a reference to ChatGPT or other AI models and software

The in-text citations and references above are adapted from the reference template for software in Section 10.10 of the Publication Manual (American Psychological Association, 2020, Chapter 10). Although here we focus on ChatGPT, because these guidelines are based on the software template, they can be adapted to note the use of other large language models (e.g., Bard), algorithms, and similar software.

The reference and in-text citations for ChatGPT are formatted as follows:

• Parenthetical citation: (OpenAI, 2023)
• Narrative citation: OpenAI (2023)

Let’s break that reference down and look at the four elements (author, date, title, and source):

Author: The author of the model is OpenAI.

Date: The date is the year of the version you used. Following the template in Section 10.10, you need to include only the year, not the exact date. The version number provides the specific date information a reader might need.

Title: The name of the model is “ChatGPT,” so that serves as the title and is italicized in your reference, as shown in the template. Although OpenAI labels unique iterations (i.e., ChatGPT-3, ChatGPT-4), they are using “ChatGPT” as the general name of the model, with updates identified with version numbers.

The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling the versions. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.

Bracketed text is used in references for additional descriptions when they are needed to help a reader understand what’s being cited. References for a number of common sources, such as journal articles and books, do not include bracketed descriptions, but things outside of the typical peer-reviewed system often do. In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model. The goal of the bracketed text is to briefly describe the kind of model to your reader.

Source: When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. This is the case for ChatGPT. The URL for ChatGPT is https://chat.openai.com/chat . For other models or products for which you may create a reference, use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage).

Other questions about citing ChatGPT

You may have noticed the confidence with which ChatGPT described the ideas of brain lateralization and how the brain operates, without citing any sources. I asked for a list of sources to support those claims and ChatGPT provided five references—four of which I was able to find online. The fifth does not seem to be a real article; the digital object identifier given for that reference belongs to a different article, and I was not able to find any article with the authors, date, title, and source details that ChatGPT provided. Authors using ChatGPT or similar AI tools for research should consider making this scrutiny of the primary sources a standard process. If the sources are real, accurate, and relevant, it may be better to read those original sources to learn from that research and paraphrase or quote from those articles, as applicable, than to use the model’s interpretation of them.

We’ve also received a number of other questions about ChatGPT. Should students be allowed to use it? What guidelines should instructors create for students using AI? Does using AI-generated text constitute plagiarism? Should authors who use ChatGPT credit ChatGPT or OpenAI in their byline? What are the copyright implications ?

On these questions, researchers, editors, instructors, and others are actively debating and creating parameters and guidelines. Many of you have sent us feedback, and we encourage you to continue to do so in the comments below. We will also study the policies and procedures being established by instructors, publishers, and academic institutions, with a goal of creating guidelines that reflect the many real-world applications of AI-generated text.

For questions about manuscript byline credit, plagiarism, and related ChatGPT and AI topics, the APA Style team is seeking the recommendations of APA Journals editors. APA Style guidelines based on those recommendations will be posted on this blog and on the APA Style site later this year.

Update: APA Journals has published policies on the use of generative AI in scholarly materials .

We, the APA Style team humans, appreciate your patience as we navigate these unique challenges and new ways of thinking about how authors, researchers, and students learn, write, and work with new technologies.

Carlton's medical staff under fire as Charlie Curnow aggravates existing ankle injury in horror loss to Hawthorn

Sport Carlton's medical staff under fire as Charlie Curnow aggravates existing ankle injury in horror loss to Hawthorn

Carltons face a nervous wait to learn the full toll of its 74-point hiding from Hawthorn after Charlie Curnow was one of several stars injured in the humiliating defeat.

The Blues' finals hopes were dealt a savage blow in the 16.16 (112) to 5.8 (38) loss on Sunday, which sent them tumbling out of the top eight with two rounds left.

Michael Voss's side should start favourites against West Coast (away) and St Kilda as they fight to keep their season alive.

But they are sweating on further assessment of injuries sustained against the Hawks by Curnow (ankle), Adam Saad (hamstring), Jack Martin (hamstring), Lachie Fogarty (collarbone) and Jordan Boyd (adductor).

"It's not ideal but at the same time we'll find out a bit about us in the next couple of weeks," Voss said.

"It's a bit of a blow how the day panned out but there's an opportunity that's sitting right in front of us and you don't wish those away.

"We're going to see it out as strong as we can and we've got to put some excitement around that."

Curnow had been nursing an ankle complaint in recent weeks and was in doubt to face Hawthorn.

The two-time Coleman Medal winner crumbled to the turf early in the second half and had to be helped from the field.

"He was fine to go. He got through parts of training a couple of days ago, got running again yesterday," Voss said.

"Unfortunately it's just a bit of a niggle that players get at this stage of the year and it's one of those that we're just going to have to manage.

"We'll just take 24 hours and make sure that we get the right assessment."

Carlton's heaviest defeat in three seasons under Voss was also their fifth in the past six weeks in a horror run.

The Blues sat second after round 19 but must now win their two remaining games and hope other results fall their way in order to reach the finals.

"We're not going to lie down," Voss said.

"We're coming forward and we're going to finish off the season strong.

"There will be something in this response.

"It's not going to get given to us, clearly. We've got to earn the right."

Elsewhere on Sunday, Adelaide upset the Western Bulldogs by 39 points , while St Kilda recorded a comfortable 48-point win over Richmond at Docklands Stadium.

A look at the AFL ladder after Round 22

What a weekend of footy that was!

It's been another round of massive moving and shaking up and down the ladder, but here's how it looks at the end of the nine matches.

FULL-TIME: Adelaide 17.9 (111) def. Western Bulldogs 9.18 (72)

The Western Bulldogs' top-four hopes are all but over after a Darcy Fogarty-inspired Adelaide romped to an upset 39-point AFL victory at Adelaide Oval.

In his 100th game, Fogarty kicked an equal career-high five goals and handed off another to guide the Crows to the 17.9 (111) to 9.18 (72) victory on Sunday.

The Bulldogs were riding a four-match winning streak and would have risen to within a victory of the teams sitting second to fourth if they had beaten the Crows.

But the loss leaves Luke Beveridge's men in seventh spot with a 12-9 record, two wins adrift of the top four with just two rounds remaining.

Even if the Bulldogs beat North Melbourne and GWS in the final two rounds, it's unlikely to be enough for them to snare a second-chance position in the finals.

The Bulldogs were their own worst enemy in front of goal against Adelaide, with Sam Darcy (1.5 and one out of bounds) the worst offender.

Darcy's sole goal came from three metres out with just over two minutes remaining in the match.

Goalkicking aside, the 21-year-old was prominent throughout with 21 disposals, five marks and a game-high 11 score involvements.

Marcus Bontempelli overcame a quiet start to finish with 26 possessions and two goals, but he tallied only two clearances and didn't have his usual impact.

Matt Crouch (32 disposals, seven clearances) and Lachlan Sholl (34 disposals) racked up big numbers for Adelaide, while Reilly O'Brien (59 hit-outs) monstered Tim English (15 hitouts) in the ruck.

Although the Bulldogs won the inside 50m count 59-43, Adelaide kicked 6.1 from centre clearances in an impressive display.

The only concern for Adelaide was an injury to Tex Walker, who was subbed off in the third quarter after being accidentally poked in the right eye by English.

The Crows stunned the Bulldogs with five goals to one in the opening quarter.

Alarm bells were ringing when Ben Keays's third goal of the match late in the second quarter extended the margin to 33 points.

Bontempelli, who had been held to just nine disposals up until that moment, won a free kick in the dying seconds of the half before converting after the siren to give his team a pulse at the long break.

A strong mark and goal by Bontempelli to start the third quarter reduced the gap to 20 points, but it was the Fogarty show for the rest of the term.

He kicked two goals and set up another to Josh Rachele as the margin ballooned to 41 points at three-quarter time.

Star Bulldogs forward Aaron Naughton was subbed off with six minutes remaining in the third quarter in a surprise tactical move.

Naughton had just four disposals and a single behind to his name.

Fogarty kicked his fifth goal in the last quarter, but the biggest cheers were saved for Daniel Curtin when the No.8 pick from last year's draft slotted the first two goals of his career.

ADEL vs WB: Darcy finally gets on the scoreboard

Sam Darcy finally kicks his goal, on his sixth attempt!

Adelaide has definitely taken the foot off the gas, but the Bulldogs have been much better in this final term.

Darcy has been one of their best. He's got 19 disposals, five marks and a game-high 11 score involvements.

ADEL vs WB: Curtin doubles up with two in the quarter

Dan Curtin having fun in the forward line here in the final term!

He gets out the back of the Bulldogs defence to take a mark inside 50 and he goes back and slots his second goal in the quarter.

Curtin's had 10 disposals to go along with his two goals and also has three clearances too.

Standing at 197cm, you get the sense that this young man could be just about anything in a couple of years.

ADEL vs WB: McNeil finally gets one on the mark for Bulldogs

Lachie McNeil snaps one through in heavy, heavy traffic and that's the Bulldogs' first goal of the quarter.

He's had 15 disposals, 10 of them contested, to go along with this goal, a pretty solid outing today.

ADEL vs WB: Curtin opens his AFL account

It just keeps getting better and better for the Crows!

Dan Curtin, last year's No.8 pick, takes a contested mark inside 50, but is called to play on, not a problem.

He swings onto his left boot and slots it and is mobbed by every one of his teammates.

What a way to kick your first goal at the AFL level.

ADEL vs WB: Fogarty equals career-best in milestone match

This play sums up the entire match.

Lachie Bramble is streaming forward for the Dogs and has Buku Khamis out in acres of space, but instead goes for a delicate kick inboard to Jamarra Ugle-Hagan, and kicks it over his head.

Adelaide capitalises on the turnover by going all the way down the other end virtually untouched.

Darcy Fogarty eventually snaps it through for an equal career-high five goals. What a 100th game it has been for the Crows forward!

ADEL vs WB: Dogs' woeful kicking continues

The Bulldogs have been their own worst enemies this afternoon.

Three set shot misses in the first five minutes of the final quarter, two to Sam Darcy and one to Cody Weightman, have snuffled out their comeback attempt.

Darcy has been horrible in front of goal today, kicking 0.5.

"They're going to have to do something about this kicking, it's a joke," says Adelaide great Mark Ricciuto on Fox Footy.

ADEL vs WB, 3QT: Adelaide 14.7 (91) leads Western Bulldogs 6.14 (50)

Two late goals to Josh Rachele and Riley Thilthorpe have blown Adelaide's lead out to a game-high 41 points!

The Bulldogs have just been incredibly inefficient going forward all afternoon, and they've been made to pay in a major way.

Adelaide has converted almost 63 per cent of its 35 inside 40s into a score, but the Bulldogs have only converged 42.5 per cent of their 40 inside 50s into a score.

Darcy Fogarty has been a wrecking ball up forward for the Crows. He's got four goals in just seven possessions and has also taken seven marks.

Fogarty also has eight score involvements, trailing only Ben Keays and Sam Darcy, who have nine apiece in that department.

ADEL vs WB: Naughton hooked by Bulldogs coach

A massive call here from Luke Beveridge, as he activates his sub.

Caleb Daniel is coming on as the sub and surprisingly he's replacing star forward Aaron Naughton, who is being managed.

It's been a tough old afternoon for Naughton, who managed just four disposals and two marks and didn't kick a goal before he was subbed out.

FULL-TIME: St Kilda 15.9 (99) def. Richmond 7.9 (51)

Ruckman Rowan Marshall has stood tall to lead St Kilda to a 48-point win over Richmond and condemn the battling Tigers to an eighth consecutive AFL loss.

Already out of finals contention, the Saints were seeking a response to their thumping 85-point loss to Brisbane and Marshall kicked three goals to help deliver a 15.9 (99) to 7.9 (51) win at Docklands Stadium on Sunday.

St Kilda (9-12) sit 14th while injury-ravaged Richmond (2-19) are last, behind North Melbourne on percentage.

The victory also ensured St Kilda's week ended on a high note, after they faced scrutiny and supporter backlash following talent manager Graeme Allan's meeting with disgraced ex-North Melbourne player Tarryn Thomas.

On Thursday the Saints confirmed they would not bid to recruit Thomas, after coach Ross Lyon had refused to answer questions about him.

Arguably St Kilda's most influential player, Marshall took on Toby Nankervis and kicked three goals, along with registering 25 hitouts, 11 marks and 23 disposals.

Gun midfielder Jack Sinclair (29 touches) was typically prolific, as was intercepting defender Josh Battle (28 disposals, nine marks), while Cooper Sharman (two goals) and Tim Membrey (three goals) hit the scoreboard.

Richmond gun Daniel Rioli (36 disposals, 10 marks) showed off his class throughout, and midfielders Tim Taranto, Sam Banks (25 disposals apiece) and Jacob Hopper (28 disposals) were busy.

Young tall Jacob Bauer kicked two goals, along with Hugo Ralphsmith and Shai Bolton.

Saints young gun Mattaes Phillipou (illness) withdrew before the first bounce, with midfielder Paddy Dow recalled in his place.

The first quarter proved an arm-wrestle, but Marshall stepped up, with his late goal from long range giving the Saints a six-point lead at the first change.

St Kilda led by 25 midway through the second term via an unanswered run of four majors, but the Tigers fought their way back into the game, trailing   by 14 points at half-time.

The Saints absorbed Richmond's pressure and steadied in the third term to take a four-goal lead into the final quarter.

Marshall received a free kick and kicked his third early in the term and the Saints didn't look back - ultimately kicking the final six goals of the game.

St Kilda finish their season with games against Geelong and Carlton at Docklands Stadium, while Richmond play Hawthorn, then Gold Coast, at the MCG.

ADEL vs WB: Rankine makes it two in two minutes

Adelaide right back on top now!

A lovely centering kick from Lachie Sholl and it eventually lands in the hands of Izak Rankine who snaps through his first goal of the afternoon.

Crows leading the clearances 7-0 so far in the third quarter, and this is a game-high 37-point lead now.

ADEL vs WB: Fogarty continues demolition job up forward

Darcy Fogarty is absolutely MANHANDLING Bulldogs defenders out there.

This time it's Bailey Dale who gets isolated on the big Crows forward, and Dale is flung out of the way like a rag doll as Fogarty takes another contested mark.

"That's why you do bench press," says Nick Dal Santo on Fox Footy's coverage.

Fogarty goes back and slots his fourth goal of the afternoon, and the Crows are back out to a comfortable 31-point lead.

ADEL vs WB: Fogarty nabs crucial steadier for Crows

Darcy Fogarty, putting them in the weight room!

A long kick inside 50 from the Crows sees Fogarty one out with Buku Khamis, and it's man against boys stuff this, as Fogarty just outmuscles Khamis to take a big contested mark.

He goes back and slots his third of the afternoon from close range to give the Crows a little bit of breathing space again.

That was Adelaide's 12th mark inside 50, the Dogs have managed just six.

ADEL vs WB: Bontempelli makes it two in a row

Marcus Bontempelli takes a big contested mark deep inside 50 and kicks the goal from the top of the square.

That's the Bont's second in a row and the Dogs' second in a row, and suddenly Adelaide's lead is cut down to 20 points.

Bontempelli has 12 disposals and three tackles to go along with his two majors.

The next goal is suddenly huge in this one. The Dogs have a pulse.

Footy fans rejoice in Carlton's pain

Best news l have heard all day and l don't barrack for Hawthorn - Janine

Any guesses as to which footy team Janine supports?

It could be Essendon, Collingwood, or any one of the other teams that were praying for a Carlton loss today to help their own team's finals chances.

RICH vs STK: Marshall's monster outing continues

St Kilda well on its way to a comfortable win now, leading by 30 points midway through the final term.

The sole goal in the quarter has come to St Kilda big man Rowan Marshall, who now has three for the game.

Marshall is the top-ranked player on the ground, adding 21 disposals, 10 marks, 24 hitouts and two clearances to his three majors.

ADEL vs WB, HT: Adelaide 9.6 (60) leads Western Bulldogs 4.10 (34)

A late goal from Marcus Bontempelli gives the Bulldogs a little sniff heading into the half-time interval.

The Bulldogs definitely lifted their pressure in that quarter, but somehow still lost the quarter as they got punished on the other end.

The Dogs lead the inside 50 count 28-23 and have laid six tackles inside 50 to Adelaide's one.

Adelaide's Matt Crouch leads all players with 17 disposals at half-time, while Adam Treloar is not too far behind with 14 touches of his own.
