Question Assumptions
An assumption is an unexamined belief: what we think without realizing we think it. Our inferences (also called conclusions) are often based on assumptions that we haven't thought about critically. A critical thinker, however, is attentive to these assumptions because they are sometimes incorrect or misguided. Just because we assume something is true doesn't mean it is.
Think carefully about your assumptions when finding and analyzing information but also think carefully about the assumptions of others. Whether you're looking at a website or a scholarly article, you should always consider the author's assumptions. Are the author's conclusions based on assumptions that she or he hasn't thought about logically?
Critical Questions
- What am I taking for granted?
- Am I assuming something I shouldn't?
- How can I determine whether this assumption is accurate?
- What is this author assuming?
- How can I determine if this author's assumptions are accurate?
Consider the following situations, then respond to these questions:
- Do you agree or disagree with the inference/conclusion? Why or why not?
- What assumption(s) may have led to the inference/conclusion?
- What are some alternative ways of thinking about this situation?
Situation #1
Bill needs six scholarly articles for his paper on the psychological effects of domestic violence. He searches Google for "psychological effects of domestic violence," looks through the first few hits, and finds six sources, including some articles on the websites of legitimate organizations. A few of these articles include bibliographies.
- Bill's Inference/Conclusion: I'm going to stop researching because I have my six sources.
Situation #2
Christie is researching representations of gender in popular music. She decides to search Google and, within a few minutes, locates more sources that she could possibly incorporate into her final paper.
- Christie's Inference/Conclusion: I can just use Google for my research.
Situation #3
Jennifer has decided to write her literary analysis paper on drug use in David Foster Wallace's novel, Infinite Jest (1996). She tries a few Google searches for Infinite Jest, drugs, and drug use, but she has trouble finding scholarly sources. She gives up on Google and moves on to EBSCO Academic Search Premier, one of the databases she heard about in a library instruction class. She runs a search for Infinite Jest and drug use, but she still can't find much.
- Jennifer's Inference/Conclusion: I need to change my topic.

- Critical thinking (CT) is evaluative. An evaluation is a statement that compares what is the case to a standard about how things should be. CT requires people to make lots of judgments about good and bad, right and wrong, what we should or shouldn’t do. The standard of evaluation used in critical thinking for reasoning is reliability. Good reasoning is reliable, and bad reasoning is unreliable.
- In CT, reasoning implies evaluation, both individual (“You should recycle your aluminum!”) and collective (“We should abolish the death penalty!”). Each statement can be supported by reasons, and the reasons can be evaluated as better or worse.
- In CT, truth is treated as absolute — not partial, changing, or relative to different points of view.
- The ultimate “should” in critical thinking is this: you should not contradict yourself. There are other “should” statements, but they are all based on this idea that self-contradiction is bad. Contradictory statements, by definition, cannot all be true, and based on #3 above that means they can’t be partly true, or true to some people but not others. A statement that is self-contradictory is absolutely, eternally, necessarily and inevitably not true.
If you don’t agree with one or more of the above assumptions, expect some trouble even understanding what is going on when trying to use critical thinking. The assumptions listed above are offered not to convince you to accept any of these assumptions or to “prove” them in the formal (CT) sense, but just to offer a bit more about what is assumed in this field.
There is also one more assumption to consider, that is people shouldn’t judge other people’s opinions.
Critical thinking requires energetically judging other people’s opinions (along with our own!) – not in isolation, but in relation to each other. That is, CT requires asking if the reason given to support or back up an opinion is a good one. If no good reason can be found to support an opinion, that opinion is treated as unsupported or unproved. Generally, opinions are better if proved, and not as good if unproved. By extension, there is a preference for reflective opinions arrived at through slow thinking over opinions of the moment which are formed in fast thinking.
Many people put the majority of their critical thinking energy into judging the thinking of those they disagree with. Our hope is that you will have come to understand that thinking carefully about your own beliefs is worth more of your time, and that you will have come to appreciate the vital importance of people who do not share your same ideas to your process of slow thinking.

What is Critical Thinking?
What About Assumptions?
Assumptions are beliefs or ideas that are believed to be true without proof or evidence and are used to support reasoning. This lack of verification can create bias when thinking critically. Like any human activity, the practice of critical thinking requires several basic assumptions to make sense. For people who don’t share these assumptions, the whole process can be experienced as confusing or nonsensical. Here is a partial list of assumptions that sometimes cause trouble for people new to critical thinking.
- In CT, reasoning implies evaluation, both individual (“You should recycle your aluminum!”) and collective (“We should abolish the death penalty!”). Each statement can be supported by reasons, and the reasons can be evaluated as better or worse. Although this should not be confused with opinions or facts .
- In CT, “Truth is what is so about something, the reality of the matter, as distinguished from what people wish were so, believe to be so, or assert to be so” (Ruggiero, 2015, p. 25)
- When using critical thinking you should not contradict yourself. Contradictory statements , by definition, cannot all be true, and based on #3 above that means they can’t be partly true, or true to some people but not others.
- Critical thinking requires judging other people’s opinions (along with our own!) – not in isolation, but in relation to each other.
Many people put the majority of their critical thinking energy into judging the thinking of those they disagree with (fast thinking). Our hope is that you will have come to understand that thinking carefully about your own beliefs is worth more of your time, and that you will have come to appreciate the vital importance of people who do not share your same ideas to your process of slow thinking.
Check Your Knowledge: Assumptions
Read the following statements and then determine the assumption.
The U.S. is overreacting to the growth of AI. Technology is meant to be utilized to its fullest.
“Eating healthy is important. Doctors and physical fitness advisors tell you about the advantages of health foods. Then why are these foods so expensive? Companies that sell these foods are raising prices for simple things such as fruits and vegetables….People want to be healthy but it seems that corporate America really doesn’t want to make that prospect cheap. You should avoid wasting money just to eat healthy; go buy cheap frozen vegetables at the grocery store.” (Browne & Keeley, 2018, p.56)
Taking an act or statement for granted (Merriam-Webster Online)
Judgements about good or bad, right or wrong
Evaluations for better or worse
A view or judgement

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.

- Missing commas and periods
- 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.

41+ Critical Thinking Examples (Definition + Practices)
Critical thinking is an essential skill in our information-overloaded world, where figuring out what is fact and fiction has become increasingly challenging.
But why is critical thinking essential? Put, critical thinking empowers us to make better decisions, challenge and validate our beliefs and assumptions, and understand and interact with the world more effectively and meaningfully.
Critical thinking is like using your brain's "superpowers" to make smart choices. Whether it's picking the right insurance, deciding what to do in a job, or discussing topics in school, thinking deeply helps a lot. In the next parts, we'll share real-life examples of when this superpower comes in handy and give you some fun exercises to practice it.
Critical Thinking Process Outline
Critical thinking means thinking clearly and fairly without letting personal feelings get in the way. It's like being a detective, trying to solve a mystery by using clues and thinking hard about them.
It isn't always easy to think critically, as it can take a pretty smart person to see some of the questions that aren't being answered in a certain situation. But, we can train our brains to think more like puzzle solvers, which can help develop our critical thinking skills.
Here's what it looks like step by step:
Spotting the Problem: It's like discovering a puzzle to solve. You see that there's something you need to figure out or decide.
Collecting Clues: Now, you need to gather information. Maybe you read about it, watch a video, talk to people, or do some research. It's like getting all the pieces to solve your puzzle.
Breaking It Down: This is where you look at all your clues and try to see how they fit together. You're asking questions like: Why did this happen? What could happen next?
Checking Your Clues: You want to make sure your information is good. This means seeing if what you found out is true and if you can trust where it came from.
Making a Guess: After looking at all your clues, you think about what they mean and come up with an answer. This answer is like your best guess based on what you know.
Explaining Your Thoughts: Now, you tell others how you solved the puzzle. You explain how you thought about it and how you answered.
Checking Your Work: This is like looking back and seeing if you missed anything. Did you make any mistakes? Did you let any personal feelings get in the way? This step helps make sure your thinking is clear and fair.
And remember, you might sometimes need to go back and redo some steps if you discover something new. If you realize you missed an important clue, you might have to go back and collect more information.
Critical Thinking Methods
Just like doing push-ups or running helps our bodies get stronger, there are special exercises that help our brains think better. These brain workouts push us to think harder, look at things closely, and ask many questions.
It's not always about finding the "right" answer. Instead, it's about the journey of thinking and asking "why" or "how." Doing these exercises often helps us become better thinkers and makes us curious to know more about the world.
Now, let's look at some brain workouts to help us think better:
1. "What If" Scenarios
Imagine crazy things happening, like, "What if there was no internet for a month? What would we do?" These games help us think of new and different ideas.
Pick a hot topic. Argue one side of it and then try arguing the opposite. This makes us see different viewpoints and think deeply about a topic.
3. Analyze Visual Data
Check out charts or pictures with lots of numbers and info but no explanations. What story are they telling? This helps us get better at understanding information just by looking at it.
4. Mind Mapping
Write an idea in the center and then draw lines to related ideas. It's like making a map of your thoughts. This helps us see how everything is connected.
There's lots of mind-mapping software , but it's also nice to do this by hand.
5. Weekly Diary
Every week, write about what happened, the choices you made, and what you learned. Writing helps us think about our actions and how we can do better.
6. Evaluating Information Sources
Collect stories or articles about one topic from newspapers or blogs. Which ones are trustworthy? Which ones might be a little biased? This teaches us to be smart about where we get our info.
There are many resources to help you determine if information sources are factual or not.
7. Socratic Questioning
This way of thinking is called the Socrates Method, named after an old-time thinker from Greece. It's about asking lots of questions to understand a topic. You can do this by yourself or chat with a friend.
Start with a Big Question:
"What does 'success' mean?"
Dive Deeper with More Questions:
"Why do you think of success that way?" "Do TV shows, friends, or family make you think that?" "Does everyone think about success the same way?"
"Can someone be a winner even if they aren't rich or famous?" "Can someone feel like they didn't succeed, even if everyone else thinks they did?"
Look for Real-life Examples:
"Who is someone you think is successful? Why?" "Was there a time you felt like a winner? What happened?"
Think About Other People's Views:
"How might a person from another country think about success?" "Does the idea of success change as we grow up or as our life changes?"
Think About What It Means:
"How does your idea of success shape what you want in life?" "Are there problems with only wanting to be rich or famous?"
Look Back and Think:
"After talking about this, did your idea of success change? How?" "Did you learn something new about what success means?"
8. Six Thinking Hats
Edward de Bono came up with a cool way to solve problems by thinking in six different ways, like wearing different colored hats. You can do this independently, but it might be more effective in a group so everyone can have a different hat color. Each color has its way of thinking:
White Hat (Facts): Just the facts! Ask, "What do we know? What do we need to find out?"
Red Hat (Feelings): Talk about feelings. Ask, "How do I feel about this?"
Black Hat (Careful Thinking): Be cautious. Ask, "What could go wrong?"
Yellow Hat (Positive Thinking): Look on the bright side. Ask, "What's good about this?"
Green Hat (Creative Thinking): Think of new ideas. Ask, "What's another way to look at this?"
Blue Hat (Planning): Organize the talk. Ask, "What should we do next?"
When using this method with a group:
- Explain all the hats.
- Decide which hat to wear first.
- Make sure everyone switches hats at the same time.
- Finish with the Blue Hat to plan the next steps.
9. SWOT Analysis
SWOT Analysis is like a game plan for businesses to know where they stand and where they should go. "SWOT" stands for Strengths, Weaknesses, Opportunities, and Threats.
There are a lot of SWOT templates out there for how to do this visually, but you can also think it through. It doesn't just apply to businesses but can be a good way to decide if a project you're working on is working.
Strengths: What's working well? Ask, "What are we good at?"
Weaknesses: Where can we do better? Ask, "Where can we improve?"
Opportunities: What good things might come our way? Ask, "What chances can we grab?"
Threats: What challenges might we face? Ask, "What might make things tough for us?"
Steps to do a SWOT Analysis:
- Goal: Decide what you want to find out.
- Research: Learn about your business and the world around it.
- Brainstorm: Get a group and think together. Talk about strengths, weaknesses, opportunities, and threats.
- Pick the Most Important Points: Some things might be more urgent or important than others.
- Make a Plan: Decide what to do based on your SWOT list.
- Check Again Later: Things change, so look at your SWOT again after a while to update it.
Now that you have a few tools for thinking critically, let’s get into some specific examples.
Everyday Examples
Life is a series of decisions. From the moment we wake up, we're faced with choices – some trivial, like choosing a breakfast cereal, and some more significant, like buying a home or confronting an ethical dilemma at work. While it might seem that these decisions are disparate, they all benefit from the application of critical thinking.
10. Deciding to buy something
Imagine you want a new phone. Don't just buy it because the ad looks cool. Think about what you need in a phone. Look up different phones and see what people say about them. Choose the one that's the best deal for what you want.
11. Deciding what is true
There's a lot of news everywhere. Don't believe everything right away. Think about why someone might be telling you this. Check if what you're reading or watching is true. Make up your mind after you've looked into it.
12. Deciding when you’re wrong
Sometimes, friends can have disagreements. Don't just get mad right away. Try to see where they're coming from. Talk about what's going on. Find a way to fix the problem that's fair for everyone.
13. Deciding what to eat
There's always a new diet or exercise that's popular. Don't just follow it because it's trendy. Find out if it's good for you. Ask someone who knows, like a doctor. Make choices that make you feel good and stay healthy.
14. Deciding what to do today
Everyone is busy with school, chores, and hobbies. Make a list of things you need to do. Decide which ones are most important. Plan your day so you can get things done and still have fun.
15. Making Tough Choices
Sometimes, it's hard to know what's right. Think about how each choice will affect you and others. Talk to people you trust about it. Choose what feels right in your heart and is fair to others.
16. Planning for the Future
Big decisions, like where to go to school, can be tricky. Think about what you want in the future. Look at the good and bad of each choice. Talk to people who know about it. Pick what feels best for your dreams and goals.
Job Examples
17. solving problems.
Workers brainstorm ways to fix a machine quickly without making things worse when a machine breaks at a factory.
18. Decision Making
A store manager decides which products to order more of based on what's selling best.
19. Setting Goals
A team leader helps their team decide what tasks are most important to finish this month and which can wait.
20. Evaluating Ideas
At a team meeting, everyone shares ideas for a new project. The group discusses each idea's pros and cons before picking one.
21. Handling Conflict
Two workers disagree on how to do a job. Instead of arguing, they talk calmly, listen to each other, and find a solution they both like.
22. Improving Processes
A cashier thinks of a faster way to ring up items so customers don't have to wait as long.
23. Asking Questions
Before starting a big task, an employee asks for clear instructions and checks if they have the necessary tools.
24. Checking Facts
Before presenting a report, someone double-checks all their information to make sure there are no mistakes.
25. Planning for the Future
A business owner thinks about what might happen in the next few years, like new competitors or changes in what customers want, and makes plans based on those thoughts.
26. Understanding Perspectives
A team is designing a new toy. They think about what kids and parents would both like instead of just what they think is fun.
School Examples
27. researching a topic.
For a history project, a student looks up different sources to understand an event from multiple viewpoints.
28. Debating an Issue
In a class discussion, students pick sides on a topic, like school uniforms, and share reasons to support their views.
29. Evaluating Sources
While writing an essay, a student checks if the information from a website is trustworthy or might be biased.
30. Problem Solving in Math
When stuck on a tricky math problem, a student tries different methods to find the answer instead of giving up.
31. Analyzing Literature
In English class, students discuss why a character in a book made certain choices and what those decisions reveal about them.
32. Testing a Hypothesis
For a science experiment, students guess what will happen and then conduct tests to see if they're right or wrong.
33. Giving Peer Feedback
After reading a classmate's essay, a student offers suggestions for improving it.
34. Questioning Assumptions
In a geography lesson, students consider why certain countries are called "developed" and what that label means.
35. Designing a Study
For a psychology project, students plan an experiment to understand how people's memories work and think of ways to ensure accurate results.
36. Interpreting Data
In a science class, students look at charts and graphs from a study, then discuss what the information tells them and if there are any patterns.
Critical Thinking Puzzles
Not all scenarios will have a single correct answer that can be figured out by thinking critically. Sometimes we have to think critically about ethical choices or moral behaviors.
Here are some mind games and scenarios you can solve using critical thinking. You can see the solution(s) at the end of the post.
37. The Farmer, Fox, Chicken, and Grain Problem
A farmer is at a riverbank with a fox, a chicken, and a grain bag. He needs to get all three items across the river. However, his boat can only carry himself and one of the three items at a time.
Here's the challenge:
- If the fox is left alone with the chicken, the fox will eat the chicken.
- If the chicken is left alone with the grain, the chicken will eat the grain.
How can the farmer get all three items across the river without any item being eaten?
38. The Rope, Jar, and Pebbles Problem
You are in a room with two long ropes hanging from the ceiling. Each rope is just out of arm's reach from the other, so you can't hold onto one rope and reach the other simultaneously.
Your task is to tie the two rope ends together, but you can't move the position where they hang from the ceiling.
You are given a jar full of pebbles. How do you complete the task?
39. The Two Guards Problem
Imagine there are two doors. One door leads to certain doom, and the other leads to freedom. You don't know which is which.
In front of each door stands a guard. One guard always tells the truth. The other guard always lies. You don't know which guard is which.
You can ask only one question to one of the guards. What question should you ask to find the door that leads to freedom?
40. The Hourglass Problem
You have two hourglasses. One measures 7 minutes when turned over, and the other measures 4 minutes. Using just these hourglasses, how can you time exactly 9 minutes?
41. The Lifeboat Dilemma
Imagine you're on a ship that's sinking. You get on a lifeboat, but it's already too full and might flip over.
Nearby in the water, five people are struggling: a scientist close to finding a cure for a sickness, an old couple who've been together for a long time, a mom with three kids waiting at home, and a tired teenager who helped save others but is now in danger.
You can only save one person without making the boat flip. Who would you choose?
42. The Tech Dilemma
You work at a tech company and help make a computer program to help small businesses. You're almost ready to share it with everyone, but you find out there might be a small chance it has a problem that could show users' private info.
If you decide to fix it, you must wait two more months before sharing it. But your bosses want you to share it now. What would you do?
43. The History Mystery
Dr. Amelia is a history expert. She's studying where a group of people traveled long ago. She reads old letters and documents to learn about it. But she finds some letters that tell a different story than what most people believe.
If she says this new story is true, it could change what people learn in school and what they think about history. What should she do?
The Role of Bias in Critical Thinking
Have you ever decided you don’t like someone before you even know them? Or maybe someone shared an idea with you that you immediately loved without even knowing all the details.
This experience is called bias, which occurs when you like or dislike something or someone without a good reason or knowing why. It can also take shape in certain reactions to situations, like a habit or instinct.
Bias comes from our own experiences, what friends or family tell us, or even things we are born believing. Sometimes, bias can help us stay safe, but other times it stops us from seeing the truth.
Not all bias is bad. Bias can be a mechanism for assessing our potential safety in a new situation. If we are biased to think that anything long, thin, and curled up is a snake, we might assume the rope is something to be afraid of before we know it is just a rope.
While bias might serve us in some situations (like jumping out of the way of an actual snake before we have time to process that we need to be jumping out of the way), it often harms our ability to think critically.
How Bias Gets in the Way of Good Thinking
Selective Perception: We only notice things that match our ideas and ignore the rest.
It's like only picking red candies from a mixed bowl because you think they taste the best, but they taste the same as every other candy in the bowl. It could also be when we see all the signs that our partner is cheating on us but choose to ignore them because we are happy the way we are (or at least, we think we are).
Agreeing with Yourself: This is called “ confirmation bias ” when we only listen to ideas that match our own and seek, interpret, and remember information in a way that confirms what we already think we know or believe.
An example is when someone wants to know if it is safe to vaccinate their children but already believes that vaccines are not safe, so they only look for information supporting the idea that vaccines are bad.
Thinking We Know It All: Similar to confirmation bias, this is called “overconfidence bias.” Sometimes we think our ideas are the best and don't listen to others. This can stop us from learning.
Have you ever met someone who you consider a “know it”? Probably, they have a lot of overconfidence bias because while they may know many things accurately, they can’t know everything. Still, if they act like they do, they show overconfidence bias.
There's a weird kind of bias similar to this called the Dunning Kruger Effect, and that is when someone is bad at what they do, but they believe and act like they are the best .
Following the Crowd: This is formally called “groupthink”. It's hard to speak up with a different idea if everyone agrees. But this can lead to mistakes.
An example of this we’ve all likely seen is the cool clique in primary school. There is usually one person that is the head of the group, the “coolest kid in school”, and everyone listens to them and does what they want, even if they don’t think it’s a good idea.
How to Overcome Biases
Here are a few ways to learn to think better, free from our biases (or at least aware of them!).
Know Your Biases: Realize that everyone has biases. If we know about them, we can think better.
Listen to Different People: Talking to different kinds of people can give us new ideas.
Ask Why: Always ask yourself why you believe something. Is it true, or is it just a bias?
Understand Others: Try to think about how others feel. It helps you see things in new ways.
Keep Learning: Always be curious and open to new information.
In today's world, everything changes fast, and there's so much information everywhere. This makes critical thinking super important. It helps us distinguish between what's real and what's made up. It also helps us make good choices. But thinking this way can be tough sometimes because of biases. These are like sneaky thoughts that can trick us. The good news is we can learn to see them and think better.
There are cool tools and ways we've talked about, like the "Socratic Questioning" method and the "Six Thinking Hats." These tools help us get better at thinking. These thinking skills can also help us in school, work, and everyday life.
We’ve also looked at specific scenarios where critical thinking would be helpful, such as deciding what diet to follow and checking facts.
Thinking isn't just a skill—it's a special talent we improve over time. Working on it lets us see things more clearly and understand the world better. So, keep practicing and asking questions! It'll make you a smarter thinker and help you see the world differently.
Critical Thinking Puzzles (Solutions)
The farmer, fox, chicken, and grain problem.
- The farmer first takes the chicken across the river and leaves it on the other side.
- He returns to the original side and takes the fox across the river.
- After leaving the fox on the other side, he returns the chicken to the starting side.
- He leaves the chicken on the starting side and takes the grain bag across the river.
- He leaves the grain with the fox on the other side and returns to get the chicken.
- The farmer takes the chicken across, and now all three items -- the fox, the chicken, and the grain -- are safely on the other side of the river.
The Rope, Jar, and Pebbles Problem
- Take one rope and tie the jar of pebbles to its end.
- Swing the rope with the jar in a pendulum motion.
- While the rope is swinging, grab the other rope and wait.
- As the swinging rope comes back within reach due to its pendulum motion, grab it.
- With both ropes within reach, untie the jar and tie the rope ends together.
The Two Guards Problem
The question is, "What would the other guard say is the door to doom?" Then choose the opposite door.
The Hourglass Problem
- Start both hourglasses.
- When the 4-minute hourglass runs out, turn it over.
- When the 7-minute hourglass runs out, the 4-minute hourglass will have been running for 3 minutes. Turn the 7-minute hourglass over.
- When the 4-minute hourglass runs out for the second time (a total of 8 minutes have passed), the 7-minute hourglass will run for 1 minute. Turn the 7-minute hourglass again for 1 minute to empty the hourglass (a total of 9 minutes passed).
The Boat and Weights Problem
Take the cat over first and leave it on the other side. Then, return and take the fish across next. When you get there, take the cat back with you. Leave the cat on the starting side and take the cat food across. Lastly, return to get the cat and bring it to the other side.
The Lifeboat Dilemma
There isn’t one correct answer to this problem. Here are some elements to consider:
- Moral Principles: What values guide your decision? Is it the potential greater good for humanity (the scientist)? What is the value of long-standing love and commitment (the elderly couple)? What is the future of young children who depend on their mothers? Or the selfless bravery of the teenager?
- Future Implications: Consider the future consequences of each choice. Saving the scientist might benefit millions in the future, but what moral message does it send about the value of individual lives?
- Emotional vs. Logical Thinking: While it's essential to engage empathy, it's also crucial not to let emotions cloud judgment entirely. For instance, while the teenager's bravery is commendable, does it make him more deserving of a spot on the boat than the others?
- Acknowledging Uncertainty: The scientist claims to be close to a significant breakthrough, but there's no certainty. How does this uncertainty factor into your decision?
- Personal Bias: Recognize and challenge any personal biases, such as biases towards age, profession, or familial status.
The Tech Dilemma
Again, there isn’t one correct answer to this problem. Here are some elements to consider:
- Evaluate the Risk: How severe is the potential vulnerability? Can it be easily exploited, or would it require significant expertise? Even if the circumstances are rare, what would be the consequences if the vulnerability were exploited?
- Stakeholder Considerations: Different stakeholders will have different priorities. Upper management might prioritize financial projections, the marketing team might be concerned about the product's reputation, and customers might prioritize the security of their data. How do you balance these competing interests?
- Short-Term vs. Long-Term Implications: While launching on time could meet immediate financial goals, consider the potential long-term damage to the company's reputation if the vulnerability is exploited. Would the short-term gains be worth the potential long-term costs?
- Ethical Implications : Beyond the financial and reputational aspects, there's an ethical dimension to consider. Is it right to release a product with a known vulnerability, even if the chances of it being exploited are low?
- Seek External Input: Consulting with cybersecurity experts outside your company might be beneficial. They could provide a more objective risk assessment and potential mitigation strategies.
- Communication: How will you communicate the decision, whatever it may be, both internally to your team and upper management and externally to your customers and potential users?
The History Mystery
Dr. Amelia should take the following steps:
- Verify the Letters: Before making any claims, she should check if the letters are actual and not fake. She can do this by seeing when and where they were written and if they match with other things from that time.
- Get a Second Opinion: It's always good to have someone else look at what you've found. Dr. Amelia could show the letters to other history experts and see their thoughts.
- Research More: Maybe there are more documents or letters out there that support this new story. Dr. Amelia should keep looking to see if she can find more evidence.
- Share the Findings: If Dr. Amelia believes the letters are true after all her checks, she should tell others. This can be through books, talks, or articles.
- Stay Open to Feedback: Some people might agree with Dr. Amelia, and others might not. She should listen to everyone and be ready to learn more or change her mind if new information arises.
Ultimately, Dr. Amelia's job is to find out the truth about history and share it. It's okay if this new truth differs from what people used to believe. History is about learning from the past, no matter the story.

What Is Critical Thinking? | Meaning & Examples
Critical thinking is the process of analyzing information logically and overcoming assumptions, biases, and logical fallacies. Developing critical thinking skills allows us to evaluate information as objectively as possible and reach well-founded conclusions.
Critical thinking example
Thinking critically is a crucial part of academic success, professional development, civic engagement, and personal decision-making.
Table of contents
What is critical thinking, why is critical thinking important, critical thinking strategies.
Critical thinking is the process of evaluating information and arguments in a disciplined and systematic way. It involves questioning assumptions, assessing evidence, and using logical reasoning to form well-reasoned judgments.
Key critical thinking skills:
- Avoiding unfounded assumptions
- Identifying and countering biases
- Recognizing and refuting logical fallacies
These practices enable us to make informed decisions, analyze evidence objectively, consider multiple perspectives, reflect on our own biases, and seek reliable sources.
Critical thinking is enhanced by the deliberate study of biases, logical fallacies, and the different forms of reasoning:
- Deductive reasoning: Drawing specific conclusions from general premises
- Inductive reasoning: Generalizing from specific observations
- Analogical reasoning: Drawing parallels between similar situations
- Abductive reasoning: Inferring the most likely explanation from incomplete evidence
When assessing sources, critical thinking requires evaluating several factors:
- Credibility: Check the author’s qualifications and the publication’s reputation.
- Evidence: Verify that the information is supported by data and references.
- Bias: Identify any potential biases or conflicts of interest.
- Currency: Ensure the information is up-to-date and relevant.
- Purpose: Understand the motivation behind the source and whether it aims to inform, persuade, or sell.
Critical thinking is crucial to decision-making and problem-solving in many domains of life. Social media disinformation and irresponsible uses of AI make it more important than ever to be able to distinguish between credible information and misleading or false content.
Developing critical thinking skills is an essential part of fostering independent thinking, allowing us to:
- Make informed decisions
- Solve complex problems
- Evaluate the logic of arguments
In the process of developing these skills, we become less susceptible to biases, fallacies, and propaganda.
Examples of critical thinking
Critical thinking is an essential part of consuming any form of media, including news, marketing, entertainment, and social media. Media platforms are commonly used to promote biased or manipulative messages, often in a subtle way.
Critical thinking in media example
A news segment claims eating chocolate daily improves cognitive function. After reading more about the research, you find the study had a small sample size and was funded by a chocolate company, indicating bias. This leads you to conclude the claim is unreliable.
Critical thinking is fundamental in logic, math, law, science, and other academic and professional domains. The scientific method is a quintessential example of systematized critical thinking.
Critical thinking in science example
- Formulate a hypothesis.
- Design experiments.
- Analyze data.
- Draw conclusions.
- Revise the hypothesis if necessary.
Academic research requires advanced critical thinking skills.
Critical thinking academic example
- Evaluating the methodology of each study to determine their reliability and validity
- Checking for potential biases, such as funding sources or conflicts of interest
- Comparing the sample sizes and demographics of the studies to understand the context of their findings
- Synthesizing the results, highlighting common trends and discrepancies, and considering the limitations of each study
Critical thinking enhances informed decision-making by equipping us to recognize biases, identify logical fallacies, evaluate evidence, consider alternative perspectives, and learn to identify credible sources.
Key strategies:
- Recognize biases.
- Identify logical fallacies.
- Evaluate sources and evidence.
- Consider alternative perspectives.

Critical thinking is the process of independently analyzing, synthesizing, and evaluating information as a guide to behavior and beliefs.
The American Philosophical Association has defined critical thinking as "the process of purposeful, self-regulatory judgment. The process gives reasoned consideration to evidence , contexts , conceptualizations, methods, and criteria" (1990). Critical thinking is sometimes broadly defined as "thinking about thinking."
Critical thinking skills include the ability to interpret, verify, and reason, all of which involve applying the principles of logic . The process of using critical thinking to guide writing is called critical writing .
Observations
- " Critical Thinking is essential as a tool of inquiry. As such, Critical Thinking is a liberating force in education and a powerful resource in one’s personal and civic life. While not synonymous with good thinking, Critical Thinking is a pervasive and self-rectifying human phenomenon. The ideal critical thinker is habitually inquisitive, well-informed, trustful of reason, open-minded, flexible, fair-minded in evaluation, honest in facing personal biases, prudent in making judgments, willing to reconsider, clear about issues, orderly in complex matters, diligent in seeking relevant information, reasonable in the selection of criteria, focused in inquiry, and persistent in seeking results which are as precise as the subject and the circumstances of inquiry permit." (American Philosophical Association, "Consensus Statement Regarding Critical Thinking," 1990)
- Thought and Language "In order to understand reasoning [...], it is necessary to pay careful attention to the relationship between thought and language . The relationship seems to be straightforward: thought is expressed in and through language. But this claim, while true, is an oversimplification. People often fail to say what they mean. Everyone has had the experience of having their \ misunderstood by others. And we all use words not merely to express our thoughts but also to shape them. Developing our critical thinking skills, therefore, requires an understanding of the ways in which words can (and often fail to) express our thoughts." (William Hughes and Jonathan Lavery, Critical Thinking: An Introduction to the Basic Skills , 4th ed. Broadview, 2004)
- Dispositions That Foster or Impede Critical thinking "Dispositions that foster critical thinking include [a] facility in perceiving irony , ambiguity , and multiplicity of meanings or points of view; the development of open-mindedness, autonomous thought, and reciprocity (Piaget's term for the ability to empathize with other individuals, social groups, nationalities, ideologies, etc.). Dispositions that act as impediments to critical thinking include defense mechanisms (such as absolutism or primary certitude, denial, projection), culturally conditioned assumptions, authoritarianism, egocentrism, and ethnocentrism, rationalization, compartmentalization, stereotyping and prejudice." (Donald Lazere, "Invention, Critical Thinking, and the Analysis of Political Rhetoric." Perspectives on Rhetorical Invention , ed. by Janet M. Atwill and Janice M. Lauer. University of Tennessee Press, 2002)
- Critical Thinking and Composing - "[T]he most intensive and demanding tool for eliciting sustained critical thought is a well-designed writing assignment on a subject matter problem. The underlying premise is that writing is closely linked with thinking and that in presenting students with significant problems to write about—and in creating an environment that demands their best writing—we can promote their general cognitive and intellectual growth. When we make students struggle with their writing, we are making them struggle with thought itself. Emphasizing writing and critical thinking , therefore, generally increases the academic rigor of a course. Often the struggle of writing, linked as it is to the struggle of thinking and to the growth of a person's intellectual powers, awakens students to the real nature of learning." (John C. Bean, Engaging Ideas: The Professor's Guide to Integrating Writing, Critical Thinking, and Active Learning in the Classroom , 2nd ed. Wiley, 2011) - "Finding a fresh approach to a writing assignment means that you must see the subject without the blinders of preconception. When people expect to see a thing in a certain way, it usually appears that way, whether or not that is its true image. Similarly, thinking based on prefabricated ideas produces writing that says nothing new, that offers nothing important to the reader. As a writer, you have a responsibility to go beyond the expected views and present your subject so that the reader sees it with fresh eyes. . . . [C]ritical thinking is a fairly systematic method of defining a problem and synthesizing knowledge about it, thereby creating the perspective you need to develop new ideas. . . . " Classical rhetoricians used a series of three questions to help focus an argument . Today these questions can still help writers understand the topic about which they are writing. An sit? (Is the problem a fact?); Quid sit (What is the definition of the problem?); and Quale sit? (What kind of problem is it?). By asking these questions, writers see their subject from many new angles before they begin to narrow the focus to one particular aspect." (Kristin R. Woolever, About Writing: A Rhetoric for Advanced Writers . Wadsworth, 1991)

Question Assumptions. An assumption is an unexamined belief: what we think without realizing we think it. Our inferences (also called conclusions) are often based on assumptions that we haven't thought about critically. A critical thinker, however, is attentive to these assumptions because they are sometimes incorrect or misguided.
Critical thinking (CT) is evaluative. An evaluation is a statement that compares what is the case to a standard about how things should be. CT requires people to make lots of judgments about good and bad, right and wrong, what we should or shouldn't do. The standard of evaluation used in critical thinking for reasoning is reliability.
In research, for example, assumptions can significantly affect the design and interpretation of studies. Challenging Assumptions. Challenging assumptions requires a rigorous and critical approach: Evaluate whether the assumption is based on credible evidence. Question if the assumption is relevant and applicable in all situations.
Assumptions are beliefs or ideas that are believed to be true without proof or evidence and are used to support reasoning. This lack of verification can create bias when thinking critically. Like any human activity, the practice of critical thinking requires several basic assumptions to make sense. For people who don't share these assumptions ...
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.
There are many resources to help you determine if information sources are factual or not. 7. Socratic Questioning. This way of thinking is called the Socrates Method, named after an old-time thinker from Greece. It's about asking lots of questions to understand a topic.
Critical Thinking is the process of using and assessing reasons to evaluate statements, assumptions, and arguments in ordinary situations. The goal of this process is to help us have good beliefs, where "good" means that our beliefs meet certain goals of thought, such as truth, usefulness, or rationality. Critical thinking is widely ...

Distinguishing Between Inferences and Assumptions. To be skilled in critical thinking is to be able to take one's thinking apart systematically, to analyze each part, assess it for quality and then improve it. The first step in this process is understanding the parts of thinking, or elements of reasoning. These elements are: purpose, question ...
Critical thinking skills examples. There are six main skills you can develop to successfully analyze facts and situations and come up with logical conclusions: 1. Analytical thinking. Being able to properly analyze information is the most important aspect of critical thinking. This implies gathering information and interpreting it, but also ...
In decision making, critical thinking is a vital skill that allows individuals to make informed choices. It enables them to: Analyze options and their potential consequences. Evaluate the credibility of sources and the quality of information. Identify biases, assumptions, and values that may influence the decision.
The Paul-Elder framework has three components: According to Paul and Elder (1997), there are two essential dimensions of thinking that students need to master in order to learn how to upgrade their thinking. They need to be able to identify the "parts" of their thinking, and they need to be able to assess their use of these parts of thinking.
Critical Thinking 3: Assumptions. All arguments, whether inductive or deductive, begin with assumptions (also known as premises). An argument may be deductively valid (that is, if its assumptions are true then its conclusion must be true) but rendered irrelevant or unhelpful in practice by unacceptable assumptions. For example:
The critical thinking process utilizes a fact-based examination of an issue to reach a logical conclusion. This lesson demonstrates the process used to establish the origins of beliefs and ...
By encouraging open dialogue and collaborative problem-solving, you create an environment that fosters the development of critical thinking skills in others. 7. Reflect and learn from the process. The seven-step critical thinking process yields a result—and you then need to put that solution into place.
Learners should ask critical questions to deepen their own and other's learning. 3. Causal assumptions are related to how things work, and how you can impact those processes. One of mine is that sharing personal examples (narrative disclosure) encourages openness and vulnerability, as well as presents the teacher as a learner.
