Key Concepts

• A thesis is a simple sentence that combines your topic and your position on the topic.
• A thesis provides a roadmap to what follows in the paper.
• A thesis is like a wheel's hub--everything revolves around it and is attached to it.

After your prewriting activities-- such as assignment analysis and outlining--you should be ready to take the next step: writing a thesis statement. Although some of your assignments will provide a focus for you, it is still important for your college career and especially for your professional career to be able to state a satisfactory controlling idea or thesis that unifies your thoughts and materials for the reader.

Characteristics of an Effective Thesis

A thesis consists of two main parts: your overall topic and your position on that topic. Here are some example thesis statements that combine topic and position:

Sample Thesis Statements

Importance of Tone

Tone is established in the wording of your thesis, which should match the characteristics of your audience. For example, if you are a concerned citizen proposing a new law to your city's board of supervisors about drunk driving, you would not want to write this:

“It’s time to get the filthy drunks off the street and from behind the wheel: I demand that you pass a mandatory five-year license suspension for every drunk who gets caught driving. Do unto them before they do unto us!”

However, if you’re speaking at a concerned citizen’s meeting and you’re trying to rally voter support, such emotional language could help motivate your audience.

Using Your Thesis to Map Your Paper for the Reader

In academic writing, the thesis statement is often used to signal the paper's overall structure to the reader. An effective thesis allows the reader to predict what will be encountered in the support paragraphs. Here are some examples:

Use the Thesis to Map

Three Potential Problems to Avoid

Because your thesis is the hub of your essay, it has to be strong and effective. Here are three common pitfalls to avoid:

1. Don’t confuse an announcement with a thesis.

In an announcement, the writer declares personal intentions about the paper instead stating a thesis with clear point of view or position:

Write a Thesis, Not an Announcement

 2. A statement of fact does not provide a point of view and is not a thesis.

An introduction needs a strong, clear position statement. Without one, it will be hard for you to develop your paper with relevant arguments and evidence.

Don't Confuse a Fact with a Thesis

3. Avoid overly broad thesis statements

Broad statements contain vague, general terms that do not provide a clear focus for the essay.

Use the Thesis to Provide Focus

Practice writing an effective thesis

OK. Time to write a thesis for your paper. What is your topic? What is your position on that topic? State both clearly in a thesis sentence that helps to map your response for the reader.

Thesis statements, formulating a working thesis.

• Define: Explain a complex term’s meaning. Select words with disputed definitions or words that lend themselves to extended, thoughtful definition, such as “life” or “intelligence.”
• Classify: Explain a topic by categorizing it with like items. Athletes can be placed in the same category as dancers because of their training; plagiarism can be categorized as fraud.
• Compare/Contrast: Illustrate the similarities or differences between set topics, or introduce an outside idea to illuminate a difficult concept. Metaphors can be a powerful method for exploring or explaining. The circulatory system can be compared to geographical structure: it is like rivers but unlike lakes.
• Cause: Consider the cause or root of something. Was a car accident simply driver error? Or was it caused by fatigue? What about our society causes so many people to fall asleep behind the wheel? Do we live in a culture where exhaustion is promoted? Why?
• Effect: Discuss the effects of something. If obesity leads to disease, what does this suggest about policy, laws, or education? How can we avoid bad effects and replicate good ones?
• Evaluate: Determine whether something is good or bad, desirable or undesirable, ethical or unethical, effective or ineffective, etc. Or is it is somewhere in-between?
• Propose: Suggest a necessary action to take, or a solution for a problem.

Types of Thesis Statements

Thesis placement, thesis checklist.

• Specific and precise. “Vouchers are important to schools” is too vague to be useful.
• Arguable. “The Civil War was a crucial event in U.S. history” is too obvious to make a solid thesis.
• The right “size” for the assignment. “The American civil war is the defining event in our country’s history” is arguable, but probably too big to cover in a two-page paper.
• Suited to the assignment. Read back over the assignment prompt to make sure your thesis (and paper as a whole) address the right issue.
• Supported by the content of your paper. Read back over your supporting paragraphs and make sure they demonstrate what your thesis is arguing. If the paper has veered in an unexpected direction during the course of your writing process, revise your thesis to fit your evidence. It may help to write a summary sentence for each key piece of support and then compare those to your thesis statement.

How to write a thesis statement, what is a thesis statement.

Almost all of us—even if we don’t do it consciously—look early in an essay for a one- or two-sentence condensation of the argument or analysis that is to follow. We refer to that condensation as a thesis statement.

Why Should Your Essay Contain a Thesis Statement?

• to test your ideas by distilling them into a sentence or two
• to better organize and develop your argument
• to provide your reader with a “guide” to your argument

In general, your thesis statement will accomplish these goals if you think of the thesis as the answer to the question your paper explores.

How Can You Write a Good Thesis Statement?

Here are some helpful hints to get you started. You can either scroll down or select a link to a specific topic.

How to Generate a Thesis Statement if the Topic is Assigned How to Generate a Thesis Statement if the Topic is not Assigned How to Tell a Strong Thesis Statement from a Weak One

How to Generate a Thesis Statement if the Topic is Assigned

Almost all assignments, no matter how complicated, can be reduced to a single question. Your first step, then, is to distill the assignment into a specific question. For example, if your assignment is, “Write a report to the local school board explaining the potential benefits of using computers in a fourth-grade class,” turn the request into a question like, “What are the potential benefits of using computers in a fourth-grade class?” After you’ve chosen the question your essay will answer, compose one or two complete sentences answering that question.

Q: “What are the potential benefits of using computers in a fourth-grade class?” A: “The potential benefits of using computers in a fourth-grade class are . . .”

A: “Using computers in a fourth-grade class promises to improve . . .”

The answer to the question is the thesis statement for the essay.

[ Back to top ]

How to Generate a Thesis Statement if the Topic is not Assigned

Even if your assignment doesn’t ask a specific question, your thesis statement still needs to answer a question about the issue you’d like to explore. In this situation, your job is to figure out what question you’d like to write about.

A good thesis statement will usually include the following four attributes:

• take on a subject upon which reasonable people could disagree
• deal with a subject that can be adequately treated given the nature of the assignment
• express one main idea
• assert your conclusions about a subject

Let’s see how to generate a thesis statement for a social policy paper.

Brainstorm the topic . Let’s say that your class focuses upon the problems posed by changes in the dietary habits of Americans. You find that you are interested in the amount of sugar Americans consume.

You start out with a thesis statement like this:

Sugar consumption.

This fragment isn’t a thesis statement. Instead, it simply indicates a general subject. Furthermore, your reader doesn’t know what you want to say about sugar consumption.

Narrow the topic . Your readings about the topic, however, have led you to the conclusion that elementary school children are consuming far more sugar than is healthy.

You change your thesis to look like this:

Reducing sugar consumption by elementary school children.

This fragment not only announces your subject, but it focuses on one segment of the population: elementary school children. Furthermore, it raises a subject upon which reasonable people could disagree, because while most people might agree that children consume more sugar than they used to, not everyone would agree on what should be done or who should do it. You should note that this fragment is not a thesis statement because your reader doesn’t know your conclusions on the topic.

Take a position on the topic. After reflecting on the topic a little while longer, you decide that what you really want to say about this topic is that something should be done to reduce the amount of sugar these children consume.

You revise your thesis statement to look like this:

More attention should be paid to the food and beverage choices available to elementary school children.

This statement asserts your position, but the terms more attention and food and beverage choices are vague.

Use specific language . You decide to explain what you mean about food and beverage choices , so you write:

Experts estimate that half of elementary school children consume nine times the recommended daily allowance of sugar.

This statement is specific, but it isn’t a thesis. It merely reports a statistic instead of making an assertion.

Make an assertion based on clearly stated support. You finally revise your thesis statement one more time to look like this:

Because half of all American elementary school children consume nine times the recommended daily allowance of sugar, schools should be required to replace the beverages in soda machines with healthy alternatives.

Notice how the thesis answers the question, “What should be done to reduce sugar consumption by children, and who should do it?” When you started thinking about the paper, you may not have had a specific question in mind, but as you became more involved in the topic, your ideas became more specific. Your thesis changed to reflect your new insights.

How to Tell a Strong Thesis Statement from a Weak One

1. a strong thesis statement takes some sort of stand..

Remember that your thesis needs to show your conclusions about a subject. For example, if you are writing a paper for a class on fitness, you might be asked to choose a popular weight-loss product to evaluate. Here are two thesis statements:

There are some negative and positive aspects to the Banana Herb Tea Supplement.

This is a weak thesis statement. First, it fails to take a stand. Second, the phrase negative and positive aspects is vague.

Because Banana Herb Tea Supplement promotes rapid weight loss that results in the loss of muscle and lean body mass, it poses a potential danger to customers.

This is a strong thesis because it takes a stand, and because it's specific.

2. A strong thesis statement justifies discussion.

Your thesis should indicate the point of the discussion. If your assignment is to write a paper on kinship systems, using your own family as an example, you might come up with either of these two thesis statements:

My family is an extended family.

This is a weak thesis because it merely states an observation. Your reader won’t be able to tell the point of the statement, and will probably stop reading.

While most American families would view consanguineal marriage as a threat to the nuclear family structure, many Iranian families, like my own, believe that these marriages help reinforce kinship ties in an extended family.

This is a strong thesis because it shows how your experience contradicts a widely-accepted view. A good strategy for creating a strong thesis is to show that the topic is controversial. Readers will be interested in reading the rest of the essay to see how you support your point.

3. A strong thesis statement expresses one main idea.

Readers need to be able to see that your paper has one main point. If your thesis statement expresses more than one idea, then you might confuse your readers about the subject of your paper. For example:

Companies need to exploit the marketing potential of the Internet, and Web pages can provide both advertising and customer support.

This is a weak thesis statement because the reader can’t decide whether the paper is about marketing on the Internet or Web pages. To revise the thesis, the relationship between the two ideas needs to become more clear. One way to revise the thesis would be to write:

Because the Internet is filled with tremendous marketing potential, companies should exploit this potential by using Web pages that offer both advertising and customer support.

This is a strong thesis because it shows that the two ideas are related. Hint: a great many clear and engaging thesis statements contain words like because , since , so , although , unless , and however .

4. A strong thesis statement is specific.

A thesis statement should show exactly what your paper will be about, and will help you keep your paper to a manageable topic. For example, if you're writing a seven-to-ten page paper on hunger, you might say:

World hunger has many causes and effects.

This is a weak thesis statement for two major reasons. First, world hunger can’t be discussed thoroughly in seven to ten pages. Second, many causes and effects is vague. You should be able to identify specific causes and effects. A revised thesis might look like this:

Hunger persists in Glandelinia because jobs are scarce and farming in the infertile soil is rarely profitable.

This is a strong thesis statement because it narrows the subject to a more specific and manageable topic, and it also identifies the specific causes for the existence of hunger.

Developing a Thesis Statement

Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.

Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.

What is a thesis statement?

A thesis statement . . .

• Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
• Makes a promise to the reader about the scope, purpose, and direction of your paper.
• Is focused and specific enough to be “proven” within the boundaries of your paper.
• Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
• Identifies the relationships between the pieces of evidence that you are using to support your argument.

Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.

Identify a topic

Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.

Consider what your assignment asks you to do

Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

Franco’s role in the diplomatic relationships between the Allies and the Axis

This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).

Sample assignment 2

Analyze one of Homer’s epic similes in the Iliad.

The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.

This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).

Developing a Thesis Statement–Additional information

Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.

Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II

After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.

As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.

For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.

Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.

As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Derive a main point from topic

Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.

Look for patterns in your evidence

Compose a purpose statement.

Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.

• Franco first tried to negotiate with the Axis
• Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis

Possible conclusion:

Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.

• The simile compares Simoisius to a tree, which is a peaceful, natural image.
• The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.

This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.

Derive purpose statement from topic

To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.

For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.

Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:

• This paper will look at modern language to see if it reflects male dominance or female oppression.
• I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.

At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.

As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Compose a draft thesis statement

If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.

Begin with a purpose statement that you will later turn into a thesis statement.

Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.

Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.

Question-to-Assertion

If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.

Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?

Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”

Write a sentence that summarizes the main idea of the essay you plan to write.

Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.

Make a list of the ideas that you want to include; consider the ideas and try to group them.

• nature = peaceful
• war matériel = violent (competes with 1?)
• need for time and space to mourn the dead
• war is inescapable (competes with 3?)

Use a formula to arrive at a working thesis statement (you will revise this later).

• although most readers of _______ have argued that _______, closer examination shows that _______.
• _______ uses _______ and _____ to prove that ________.
• phenomenon x is a result of the combination of __________, __________, and _________.

What to keep in mind as you draft an initial thesis statement

Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.

As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.

You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.

Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.

Refine and polish the thesis statement

To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.

• Ask if your draft thesis addresses the assignment
• Question each part of your draft thesis
• Clarify vague phrases and assertions
• Investigate alternatives to your draft thesis

Consult the example below for suggestions on how to refine your draft thesis statement.

Sample Assignment

Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.

• Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.

Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.

Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.

While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.

While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.

Complete the final thesis statement

The bottom line.

As you move through the process of crafting a thesis, you’ll need to remember four things:

• Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
• As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
• Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
• Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.

In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.

You may have heard the word thesis as a standalone term or as a component of academic writing called a thesis statement . Keep in mind that these are two very different things.

• A thesis statement is a very common component of an essay, particularly in the humanities. It usually comprises 1 or 2 sentences in the introduction of your essay , and should clearly and concisely summarize the central points of your academic essay .
• A thesis is a long-form piece of academic writing, often taking more than a full semester to complete. It is generally a degree requirement for Master’s programs, and is also sometimes required to complete a bachelor’s degree in liberal arts colleges.
• In the US, a dissertation is generally written as a final step toward obtaining a PhD.
• In other countries (particularly the UK), a dissertation is generally written at the bachelor’s or master’s level.

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

The final structure of your thesis depends on a variety of components, such as:

• Your discipline
• Your theoretical approach

Humanities theses are often structured more like a longer-form essay . Just like in an essay, you build an argument to support a central thesis.

In both hard and social sciences, theses typically include an introduction , literature review , methodology section ,  results section , discussion section , and conclusion section . These are each presented in their own dedicated section or chapter. In some cases, you might want to add an appendix .

Thesis examples

We’ve compiled a short list of thesis examples to help you get started.

• Example thesis #1:   “Abolition, Africans, and Abstraction: the Influence of the ‘Noble Savage’ on British and French Antislavery Thought, 1787-1807” by Suchait Kahlon.
• Example thesis #2: “’A Starving Man Helping Another Starving Man’: UNRRA, India, and the Genesis of Global Relief, 1943-1947″ by Julian Saint Reiman.

The very first page of your thesis contains all necessary identifying information, including:

• Your full title
• Your full name
• Your department
• Your institution and degree program
• Your submission date.

Sometimes the title page also includes your student ID, the name of your supervisor, or the university’s logo. Check out your university’s guidelines if you’re not sure.

Read more about title pages

The acknowledgements section is usually optional. Its main point is to allow you to thank everyone who helped you in your thesis journey, such as supervisors, friends, or family. You can also choose to write a preface , but it’s typically one or the other, not both.

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

An abstract is a short summary of your thesis. Usually a maximum of 300 words long, it’s should include brief descriptions of your research objectives , methods, results, and conclusions. Though it may seem short, it introduces your work to your audience, serving as a first impression of your thesis.

Read more about abstracts

A table of contents lists all of your sections, plus their corresponding page numbers and subheadings if you have them. This helps your reader seamlessly navigate your document.

Your table of contents should include all the major parts of your thesis. In particular, don’t forget the the appendices. If you used heading styles, it’s easy to generate an automatic table Microsoft Word.

Read more about tables of contents

While not mandatory, if you used a lot of tables and/or figures, it’s nice to include a list of them to help guide your reader. It’s also easy to generate one of these in Word: just use the “Insert Caption” feature.

Read more about lists of figures and tables

If you have used a lot of industry- or field-specific abbreviations in your thesis, you should include them in an alphabetized list of abbreviations . This way, your readers can easily look up any meanings they aren’t familiar with.

Read more about lists of abbreviations

Relatedly, if you find yourself using a lot of very specialized or field-specific terms that may not be familiar to your reader, consider including a glossary . Alphabetize the terms you want to include with a brief definition.

Read more about glossaries

An introduction sets up the topic, purpose, and relevance of your thesis, as well as expectations for your reader. This should:

• Ground your research topic , sharing any background information your reader may need
• Define the scope of your work
• Introduce any existing research on your topic, situating your work within a broader problem or debate
• State your research question(s)
• Outline (briefly) how the remainder of your work will proceed

In other words, your introduction should clearly and concisely show your reader the “what, why, and how” of your research.

Read more about introductions

A literature review helps you gain a robust understanding of any extant academic work on your topic, encompassing:

• Selecting relevant sources
• Determining the credibility of your sources
• Critically evaluating each of your sources
• Drawing connections between sources, including any themes, patterns, conflicts, or gaps

A literature review is not merely a summary of existing work. Rather, your literature review should ultimately lead to a clear justification for your own research, perhaps via:

• Addressing a gap in the literature
• Building on existing knowledge to draw new conclusions
• Exploring a new theoretical or methodological approach
• Introducing a new solution to an unresolved problem
• Definitively advocating for one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework, but these are not the same thing. A theoretical framework defines and analyzes the concepts and theories that your research hinges on.

Read more about theoretical frameworks

Your methodology chapter shows your reader how you conducted your research. It should be written clearly and methodically, easily allowing your reader to critically assess the credibility of your argument. Furthermore, your methods section should convince your reader that your method was the best way to answer your research question.

A methodology section should generally include:

• Your overall approach ( quantitative vs. qualitative )
• Your research methods (e.g., a longitudinal study )
• Your data collection methods (e.g., interviews or a controlled experiment
• Any tools or materials you used (e.g., computer software)
• The data analysis methods you chose (e.g., statistical analysis , discourse analysis )
• A strong, but not defensive justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. These two sections work in tandem, but shouldn’t repeat each other. While your results section can include hypotheses or themes, don’t include any speculation or new arguments here.

Your results section should:

• State each (relevant) result with any (relevant) descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
• Explain how each result relates to the research question
• Determine whether the hypothesis was supported

Additional data (like raw numbers or interview transcripts ) can be included as an appendix . You can include tables and figures, but only if they help the reader better understand your results.

Read more about results sections

Your discussion section is where you can interpret your results in detail. Did they meet your expectations? How well do they fit within the framework that you built? You can refer back to any relevant source material to situate your results within your field, but leave most of that analysis in your literature review.

For any unexpected results, offer explanations or alternative interpretations of your data.

Read more about discussion sections

Your thesis conclusion should concisely answer your main research question. It should leave your reader with an ultra-clear understanding of your central argument, and emphasize what your research specifically has contributed to your field.

Why does your research matter? What recommendations for future research do you have? Lastly, wrap up your work with any concluding remarks.

Read more about conclusions

In order to avoid plagiarism , don’t forget to include a full reference list at the end of your thesis, citing the sources that you used. Choose one citation style and follow it consistently throughout your thesis, taking note of the formatting requirements of each style.

Which style you choose is often set by your department or your field, but common styles include MLA , Chicago , and APA.

Create APA citations Create MLA citations

In order to stay clear and concise, your thesis should include the most essential information needed to answer your research question. However, chances are you have many contributing documents, like interview transcripts or survey questions . These can be added as appendices , to save space in the main body.

Read more about appendices

Once you’re done writing, the next part of your editing process begins. Leave plenty of time for proofreading and editing prior to submission. Nothing looks worse than grammar mistakes or sloppy spelling errors!

Consider using a professional thesis editing service or grammar checker to make sure your final project is perfect.

Once you’ve submitted your final product, it’s common practice to have a thesis defense, an oral component of your finished work. This is scheduled by your advisor or committee, and usually entails a presentation and Q&A session.

After your defense , your committee will meet to determine if you deserve any departmental honors or accolades. However, keep in mind that defenses are usually just a formality. If there are any serious issues with your work, these should be resolved with your advisor way before a defense.

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

• Plan to attend graduate school soon
• Have a particular topic you’d like to study more in-depth
• Are considering a career in research
• Would like a capstone experience to tie up your academic experience

While Sandel argues that pursuing perfection through genetic engineering would decrease our sense of humility, he claims that the sense of solidarity we would lose is also important.

This thesis summarizes several points in Sandel’s argument, but it does not make a claim about how we should understand his argument. A reader who read Sandel’s argument would not also need to read an essay based on this descriptive thesis.  

Broad thesis (arguable, but difficult to support with evidence) 

Michael Sandel’s arguments about genetic engineering do not take into consideration all the relevant issues.

This is an arguable claim because it would be possible to argue against it by saying that Michael Sandel’s arguments do take all of the relevant issues into consideration. But the claim is too broad. Because the thesis does not specify which “issues” it is focused on—or why it matters if they are considered—readers won’t know what the rest of the essay will argue, and the writer won’t know what to focus on. If there is a particular issue that Sandel does not address, then a more specific version of the thesis would include that issue—hand an explanation of why it is important.  

Arguable thesis with analytical claim 

While Sandel argues persuasively that our instinct to “remake” (54) ourselves into something ever more perfect is a problem, his belief that we can always draw a line between what is medically necessary and what makes us simply “better than well” (51) is less convincing.

This is an arguable analytical claim. To argue for this claim, the essay writer will need to show how evidence from the article itself points to this interpretation. It’s also a reasonable scope for a thesis because it can be supported with evidence available in the text and is neither too broad nor too narrow.  

Arguable thesis with normative claim 

Given Sandel’s argument against genetic enhancement, we should not allow parents to decide on using Human Growth Hormone for their children.

This thesis tells us what we should do about a particular issue discussed in Sandel’s article, but it does not tell us how we should understand Sandel’s argument.  

Questions to ask about your thesis 

• Is the thesis truly arguable? Does it speak to a genuine dilemma in the source, or would most readers automatically agree with it?  
• Is the thesis too obvious? Again, would most or all readers agree with it without needing to see your argument?  
• Is the thesis complex enough to require a whole essay's worth of argument?  
• Is the thesis supportable with evidence from the text rather than with generalizations or outside research?  
• Would anyone want to read a paper in which this thesis was developed? That is, can you explain what this paper is adding to our understanding of a problem, question, or topic?

• Effective Thesis Statements

What is a Thesis Statement?

• A thesis statement tells a reader how you will interpret the significance of the subject matter under discussion. Such a statement is also called an “argument,” a “main idea,” or a “controlling idea.”
• A good thesis has two parts. It should tell what you plan to argue, and it should “telegraph” how you plan to argue—that is, what particular support for your claim is going where in your essay
• A standard place for your thesis is at the end of the introductory paragraph.
• A thesis is an interpretation of a subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel that others might dispute.
• A strong thesis not only grabs the interest of your reader, who now wants to see you support your unique interpretation, it also provides a focus for your argument, one to which every part of your paper refers in the development of your position.
• A thesis keeps the writer centered on the matter at hand and reduces the risk of intellectual wandering. Likewise, a thesis provides the reader with a “road map,” clearly laying out the intellectual route ahead.
• A thesis statement avoids the first person (“I believe,” “In my opinion”).

A simple equation for what a thesis might look like this:

What you plan to argue + How you plan to argue it = Thesis Specific Topic+ Attitude/Angle/Argument=Thesis

Steps To Write Effective Thesis Statement

• Choose a prompt or, if appropriate, select a topic: television violence and children
• What are the effects of television violence on children?
• Violence on television increases aggressive behavior in children.
• Avoid general phrasing and/or sweeping words such as “all” or “none” or “every”.
• Lead the reader toward the topic sentences (the subtopics needed to prove the thesis).
• While poor parenting and easy access to weapons may act as contributory factors, in fact when children are exposed to television violence they become less sensitive to the pain and suffering of others, are more fearful of the world around them, and are more likely to behave in aggressive or harmful ways toward others.

The Components of an Effective Thesis Statement

• You can’t just pluck a thesis out of thin air. Even if you have a terrific insight concerning a topic, it won’t be worth much unless you can logically and persuasively support it in the body of your essay. A thesis is the evolutionary result of a thinking process, not a miraculous creation. Formulating a thesis is not the first thing you do after reading an essay assignment .
• Substantial – Your thesis should be a claim for which it is easy to answer every reader’s question: “So what?”
• Supportable – A thesis must be a claim that you can prove with the evidence at hand (e.g., evidence from your texts or from your research). Your claim should not be outlandish, nor should it be mere personal opinion or preference (e.g., “Frederick Douglass is my favorite historical figure.”) It tackles a subject that could be adequately covered in the format of the project assigned.
• Precise – It is focused and specific. A strong thesis proves a point without discussing everything. It clearly asserts your own conclusion based on evidence. Note: Be flexible. It is perfectly okay to change your thesis!
• Arguable – It should be contestable, proposing an arguable point with which people could reasonably disagree.
• Relevant – If you are responding to an assignment, the thesis should answer the question your teacher has posed. In order to stay focused, pay attention to the task words in the assignment: summarize, argue, compare/contrast, etc.
• Aware of Counters – It anticipates and refutes the counter-arguments.

The best thesis statement is a balance of specific details and concise language. Your goal is to articulate an argument in detail without burdening the reader with too much information.

Questions To Review Your Thesis

• “Do I answer the question?” This might seem obvious, but it’s worth asking. No matter how intriguing or dazzling, a thesis that doesn’t answer the question is not a good thesis!
• “Have I taken a position that others might challenge or oppose?” If not, then you probably do not have a strong argument. Theses that are too vague often have this problem. If your thesis contains vague words like “good” or “successful,” see if you could be more specific: why is something “good”; what makes something “successful”?
• Would anyone possible care about this thesis? So What? Does your thesis present a position or an interpretation worth pursuing? If a reader’s first response is, “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• “Does my essay support my thesis specifically and without wandering?” Just as a thesis that doesn’t answer the question ultimately fails, so does a thesis that isn’t properly supported with evidence and reasoning.
• Does my thesis statement adequately address the direction words of the prompt: summarize, argue, compare/contrast, analyze, discuss, etc.?

Myths about Thesis Statements

• Every paper requires one . Assignments that ask you to write personal responses or to explore a subject don’t want you to seem to pre-judge the issues. Essays of literary interpretation often want you to be aware of many effects rather than seeming to box yourself into one view of the text.
• A thesis statement must come at the end of the first paragraph . This is a natural position for a statement of focus, but it’s not the only one. Some theses can be stated in the opening sentences of an essay; others need a paragraph or two of introduction; others can’t be fully formulated until the end.
• A thesis statement must be one sentence in length , no matter how many clauses it contains. Clear writing is more important than rules like these. Use two or three sentences if you need them. A complex argument may require a whole tightly-knit paragraph to make its initial statement of position.
• You can’t start writing an essay until you have a perfect thesis statement . It may be advisable to draft a hypothesis or tentative thesis statement near the start of a big project, but changing and refining a thesis is a main task of thinking your way through your ideas as you write a paper. And some essay projects need to explore the question in depth without being locked in before they can provide even a tentative answer.
• A thesis statement must give three points of support . It should indicate that the essay will explain and give evidence for its assertion, but points don’t need to come in any specific number.

Developing Strong Thesis Statements

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

The thesis statement or main claim must be debatable

An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words, the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people.

Example of a non-debatable thesis statement:

This thesis statement is not debatable. First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem. No one could reasonably argue that pollution is unambiguously good.

Example of a debatable thesis statement:

This is an example of a debatable thesis because reasonable people could disagree with it. Some people might think that this is how we should spend the nation's money. Others might feel that we should be spending more money on education. Still others could argue that corporations, not the government, should be paying to limit pollution.

Another example of a debatable thesis statement:

In this example there is also room for disagreement between rational individuals. Some citizens might think focusing on recycling programs rather than private automobiles is the most effective strategy.

The thesis needs to be narrow

Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.

Example of a thesis that is too broad:

There are several reasons this statement is too broad to argue. First, what is included in the category "drugs"? Is the author talking about illegal drug use, recreational drug use (which might include alcohol and cigarettes), or all uses of medication in general? Second, in what ways are drugs detrimental? Is drug use causing deaths (and is the author equating deaths from overdoses and deaths from drug related violence)? Is drug use changing the moral climate or causing the economy to decline? Finally, what does the author mean by "society"? Is the author referring only to America or to the global population? Does the author make any distinction between the effects on children and adults? There are just too many questions that the claim leaves open. The author could not cover all of the topics listed above, yet the generality of the claim leaves all of these possibilities open to debate.

Example of a narrow or focused thesis:

In this example the topic of drugs has been narrowed down to illegal drugs and the detriment has been narrowed down to gang violence. This is a much more manageable topic.

We could narrow each debatable thesis from the previous examples in the following way:

Narrowed debatable thesis 1:

This thesis narrows the scope of the argument by specifying not just the amount of money used but also how the money could actually help to control pollution.

Narrowed debatable thesis 2:

This thesis narrows the scope of the argument by specifying not just what the focus of a national anti-pollution campaign should be but also why this is the appropriate focus.

Qualifiers such as " typically ," " generally ," " usually ," or " on average " also help to limit the scope of your claim by allowing for the almost inevitable exception to the rule.

Types of claims

Claims typically fall into one of four categories. Thinking about how you want to approach your topic, or, in other words, what type of claim you want to make, is one way to focus your thesis on one particular aspect of your broader topic.

Claims of fact or definition: These claims argue about what the definition of something is or whether something is a settled fact. Example:

Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:

Claims about value: These are claims made of what something is worth, whether we value it or not, how we would rate or categorize something. Example:

Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:

Which type of claim is right for your argument? Which type of thesis or claim you use for your argument will depend on your position and knowledge of the topic, your audience, and the context of your paper. You might want to think about where you imagine your audience to be on this topic and pinpoint where you think the biggest difference in viewpoints might be. Even if you start with one type of claim you probably will be using several within the paper. Regardless of the type of claim you choose to utilize it is key to identify the controversy or debate you are addressing and to define your position early on in the paper.

A good thesis statement can be the difference between making an argument about something, and simply re-stating what someone else has already said. In your thesis statement, you want to make a claim that you will continue to develop throughout the paper. It should represent your own ideas–perhaps in response to something someone else has said–but ultimately, it is your argument. As such, a good thesis statement should have 3 main traits. A good thesis:

• Can be developed with evidence throughout your paper. In other words, you should be able to say it in 1-2 sentences, but that shouldn’t be all that there is to say on the topic.
• Is argumentative, not in a negative sense, but in that it can be supported and may have counter-arguments. Test this by asking “Could I argue the reverse of this?”
• Should explain what, why, and how. What are you arguing? Why are you arguing that? And how will you show it? Think of the “what” as your basic position, the “why” as your reasoning, and the “how” as your evidence (theories, sources, etc.)

In all, the thesis is the backbone of your paper. In the rest of your paper, something in each paragraph should directly relate back to the paper. If you get lost in the writing process, you’ll want to be able to come back to your thesis and say, “this is what I’m arguing.” And remember, thesis statements can evolve with the paper. Once you’ve got your draft written, read through and make sure that what you’re saying in your paper matches up with what your thesis statement says you’re going to be saying.

H ere are a few helpful links to get you started:

Here’s another great source from the University of North Carolina with some tips and examples of strong thesis statements.

It can be useful to play around with and see examples, but DO NOT use it to create your actual thesis, as this may be considered plagiarism!

How to write a thesis statement + examples

What is a thesis statement?

Is a thesis statement a question, how do you write a good thesis statement, how do i know if my thesis statement is good, examples of thesis statements, helpful resources on how to write a thesis statement, frequently asked questions about writing a thesis statement, related articles.

A thesis statement is the main argument of your paper or thesis.

The thesis statement is one of the most important elements of any piece of academic writing . It is a brief statement of your paper’s main argument. Essentially, you are stating what you will be writing about.

You can see your thesis statement as an answer to a question. While it also contains the question, it should really give an answer to the question with new information and not just restate or reiterate it.

Your thesis statement is part of your introduction. Learn more about how to write a good thesis introduction in our introduction guide .

A thesis statement is not a question. A statement must be arguable and provable through evidence and analysis. While your thesis might stem from a research question, it should be in the form of a statement.

Tip: A thesis statement is typically 1-2 sentences. For a longer project like a thesis, the statement may be several sentences or a paragraph.

A good thesis statement needs to do the following:

• Condense the main idea of your thesis into one or two sentences.
• Answer your project’s main research question.
• Clearly state your position in relation to the topic .
• Make an argument that requires support or evidence.

Once you have written down a thesis statement, check if it fulfills the following criteria:

• Your statement needs to be provable by evidence. As an argument, a thesis statement needs to be debatable.
• Your statement needs to be precise. Do not give away too much information in the thesis statement and do not load it with unnecessary information.
• Your statement cannot say that one solution is simply right or simply wrong as a matter of fact. You should draw upon verified facts to persuade the reader of your solution, but you cannot just declare something as right or wrong.

As previously mentioned, your thesis statement should answer a question.

If the question is:

What do you think the City of New York should do to reduce traffic congestion?

A good thesis statement restates the question and answers it:

In this paper, I will argue that the City of New York should focus on providing exclusive lanes for public transport and adaptive traffic signals to reduce traffic congestion by the year 2035.

Here is another example. If the question is:

How can we end poverty?

A good thesis statement should give more than one solution to the problem in question:

In this paper, I will argue that introducing universal basic income can help reduce poverty and positively impact the way we work.

• The Writing Center of the University of North Carolina has a list of questions to ask to see if your thesis is strong .

A thesis statement is part of the introduction of your paper. It is usually found in the first or second paragraph to let the reader know your research purpose from the beginning.

In general, a thesis statement should have one or two sentences. But the length really depends on the overall length of your project. Take a look at our guide about the length of thesis statements for more insight on this topic.

Here is a list of Thesis Statement Examples that will help you understand better how to write them.

Every good essay should include a thesis statement as part of its introduction, no matter the academic level. Of course, if you are a high school student you are not expected to have the same type of thesis as a PhD student.

Writing an Effective Thesis Statement

Writing an Effective Thesis Statement Podcast

Writing an effective thesis statement transcript.

Greetings everyone. This is Kurtis Clements with another effective writing podcast. In this episode, I am going to discuss how to write an effective thesis statement. One issue to keep in mind when you write is that your words need to stand on their own. It is your responsibility to express your thoughts in a way that others can understand. Think of it this way: You will not be around to explain to readers what you meant by a certain remark or to offer another example to illustrate a fuzzy point. Indeed, the words in your composition will have to communicate meaning without your presence. What you do not want to have happen is for your audience to reach the end of a piece of your written communication and say, “So what? What’s the point?”

The “so what” of a piece of writing is the specific point the piece makes, what the writing says about its subject. The “so what” is what the writing adds up to. It is the meaning found in the writing. The “so what” of an informative essay may be Boston has a lot to offer young children. The “so what” of a business memo may be profits have exceeded expectations.

No matter the type of composition, the piece of writing must communicate meaning, not to the writer, but, rather, to an audience. The meaning found in a piece of writing, the “so what,” is the most important aspect of any piece of writing, for what good would a piece of writing be if it did not add up to something, if it did not say something to an audience? When you are working on a composition, you will need to think about what you are trying to say so that you are in a position to make sure that what you are trying to communicate is, in fact, communicated.

I know what you’re thinking: What’s all this have to do with a thesis statement? The answer: everything! Let me explain.

Every composition needs to make a clear point about its topic—otherwise, what purpose would the writing serve? One way to ensure that readers will follow along in the development of an essay is by including a written out thesis statement (more on this in just a moment). The word thesis comes from a Greek word that means “proposition” or “position.” In an essay, the thesis establishes the writer’s position, the main idea of the paper, what the writer claims to be true or important about the topic. A thesis helps readers understand the direction the essay is heading and it connects body paragraphs to a controlling idea so that the essay comes together as a unified whole.

Most thesis statements are expressed in a single declarative sentence, but depending on a number of factors such as the scope and complexity of the topic or the writer’s approach in discussing it, the thesis may require more than one sentence, but this is the exception rather than the rule. In most academic writing, the thesis will appear near or at the end of the introduction and announce to readers exactly what the body paragraphs that follow will discuss. In some writing, especially personal writing, a written-out thesis may not be necessary, but regardless the focus of the paper still needs to be clear. So, whether the thesis is written out verbatim or not, the thesis of the paper—what it will discuss—still needs to be clear.

Constructing a thesis statement will take time; in fact, like writing itself, developing a thesis is a process, so you will need to be patient and be willing to revise as necessary. A good thesis comes about the more you explore your topic whether that exploration is the result of exploratory writing like freewriting or research or long walks in which you think and think and think.

As you explore your thinking, your ideas will get clearer and clearer. Again, a thesis statement evolves over time. Begin with a working thesis—your tentative ideas about a topic—and be willing to modify the statement depending on what you discover about your topic and how your thinking changes over time. Indeed, many writers find themselves in jams because they are unwilling to deviate from their original thesis and are bent on trying to support ideas that are unrealistic, perhaps even impossible.

Still worse, some writers try to force the content to fit the idea expressed in the thesis. This won’t work. In fact, some writers approach their work so that the thesis emerges out of the writing. That’s right! Some writers don’t start with a thesis—working or otherwise—and, instead, explore their thinking in writing as a way to discover what it is they have to say about a topic. The fabulous Donald Murray, a journalist and famous writer about the process of writing, worked this way. And other writers work this way, too. And of course, many writers do not work this way and the truth is the actual process you use to develop a thesis does not matter so long as the end result is successful.

As you approach drafting a thesis, make sure you keep your purpose for writing in mind. Will you be informing? Persuading? Entertaining? Complaining? Whatever the case, you will want that purpose to be apparent from the construction of the thesis.

One good way to come up with ideas that you can use to construct a working thesis is to explore your thoughts. What do you already know about the topic? Use freewriting (or some other exploratory writing method such as brainstorming) to capture what you already know and think about the topic. Roll up your sleeves and spend 10, 15, or more minutes just writing. Write about what interests you about the topic and what you might like to know. Explore freely what is bouncing around inside your head and do not be afraid to follow your thinking wherever it takes you. Writing is an act of discovery, and you might stumble upon an interesting angle to pursue if you give yourself permission to explore. After you’ve written for a period of time, look over your writing and see if any dominant idea emerges or if some of the writing suggests a direction worth thinking about more. In a perfect world, the freewriting will produce enough of your ideas that you can almost see the beginning of a thesis.

Another good approach to producing a thesis is to conduct some research. Some assignments may not benefit from this tip, but many—even those that don’t specifically require research—will. To this end, peruse the library whether you do so physically or virtually. Poke and read around about your topic, following the discussion here and there depending on what interests you. Take some notes as you see fit.

You could also ask questions about what you wonder or would like to know about your topic. Do big-box stores such as Home Depot and Wal-Mart have an impact on local economies? What are the benefits of a vegan lifestyle? How costly are green energy sources? What steps should individuals take to safeguard against identity fraud? Avoid yes/no type questions and research accordingly. A good research question can lend itself to the development of a working thesis in that the “answer” can serve as a starting point.

So what are the characteristics of an effective thesis statement?

An effective thesis statement establishes one major idea. If a thesis introduces more than one idea, the paper will not have a tight focus. Most papers you will write will be relatively short and do not have room to discuss more than one major idea. Pay particular attention to your thesis statement if it includes the word “and” as this connecting word often joins new ideas. Note how the following thesis has more than one main idea: Healthcare reform must be addressed because so many Americans are uninsured or without adequate coverage, and politicians must work together to ensure new legislation is passed. In this example, the word “and” establishes an additional main idea and so the thesis lacks a clearly defined focus. To improve upon the thesis, the thesis would need to be streamlined and focus on one main idea. For example, a better thesis might be Politicians must work together to reform healthcare because too many Americans are without sufficient coverage.

An effective thesis statement is limited in scope. The thesis should limit the extent of the discussion to something manageable given the assignment—neither too broad nor too narrow. The thesis should establish a focus that is realistic and suitable for a substantive discussion of the main idea. Taking a stand on capital punishment, for example, is not realistic for a short research paper let alone an entire book—the topic is too broad. However, limiting the focus by narrowing the scope may work. You could argue that capital punishment does not reduce the crime rate or that lethal injection is the most humane form of capital punishment. In this way, the focus is something that realistically could be addressed in the paper.

An effective thesis statement clearly states the writer’s position. The thesis should state precisely and specifically what the paper will discuss. After reading the thesis, readers should know exactly what to expect. Avoid language that is too general, abstract, or otherwise confusing. If your thesis does not clearly establish your main idea, readers may have a difficult time following the development of the body paragraphs that follow. Here is an example of a thesis statement that is vague: Television violence is an issue that many face. Based on this thesis, do you understand what the writer is going to explore in the paper? Sure, television violence, but beyond that general subject, do you have any clear sense of what the writer will be exploring? Not at all! This thesis lacks the specificity it needs to orient readers appropriately so that they know what to expect in the discussion.

An effective thesis statement requires supporting evidence. The thesis expresses an idea that moves beyond a statement of fact and requires supporting content to “prove” the main idea. For example, a thesis that proclaims Barack Obama is the first African-American to be elected president of the United States would not be very good as it states a widely known fact. A better thesis might proclaim this: Barack Obama’s election as president of the United States marked a seminal moment in American politics. The revised thesis moves beyond simply stating a fact and, instead, presents a main idea that would require evidence to support.

There are two basic approaches to composing a thesis—forecasting the main points by embedding them in the thesis (an approach commonly referred to as the three-point thesis) or not including the main points in the thesis. Your approach will depend on the topic you are addressing as well as any particular requirements of the assignment.

A three-point thesis states the main idea of the essay and includes three key points as support. Take a look at the following thesis: Banning cigarette smoking in public places is an effective intervention to improve the public’s health by helping to reduce the dangers of second-hand smoke on non-smokers, encouraging current smokers to quit, and reducing healthcare costs. In this example, the main idea—the position the writer takes relative to the topic—is Banning cigarette smoking in public places is an effective intervention to improve the public’s health. This part of the thesis states what the writer claims to be true about the topic. How will the writer support this view? In this case, the thesis includes three telegraphed key points—by helping to reduce the dangers of second-hand smoke on non-smokers, encouraging current smokers to quit, and reducing healthcare costs.

The three-point thesis is the blueprint of the essay in that it not only establishes the main idea, but it also fleshes out the key points to that readers can anticipate a basic structure of the essay. Readers would expect each forecasted point to be discussed in the order presented—that is, the first section will discuss the first key point, the next section the second, and so on.

Another approach to composing a thesis is to state the main idea minus the key points. Using the example above, the thesis would read: Banning cigarette smoking in public places is an effective intervention to improve the public’s health. With this approach, the key points are not included in the thesis, yet the focus and direction are clear. Readers may not know the exact key points, but they understand the writer’s position on the topic and can anticipate the likely discussion that will follow. In this case, since the main idea states the view that banning smoking in public is an effective intervention to improve public health, it is logical to expect key points that address how this is so.

Please keep in mind that writing a good thesis is a process and a process requires time. While some folks might be able to come up with a humdinger of a thesis from the get-go that is not the norm. To this end, give yourself time to explore your topic and don’t be impatient. Draft a working thesis and revise as necessary. I hope you find this podcast helpful.

Thanks, everyone. Happy writing!

How to Write a Strong Thesis Statement

A thesis can be found in many places—a debate speech, a lawyer’s closing argument, even an advertisement. But the most common place for a thesis statement (and probably why you’re reading this article) is in an essay.

Whether you’re writing an argumentative paper, an informative essay, or a compare/contrast statement, you need a thesis. Without a thesis, your argument falls flat and your information is unfocused. Since a thesis is so important, it’s probably a good idea to look at some tips on how to put together a strong one.

Guide Overview

What is a “thesis statement” anyway.

• 2 categories of thesis statements: informative and persuasive
• 2 styles of thesis statements
• Formula for a strong argumentative thesis
• The qualities of a solid thesis statement (video)

You may have heard of something called a “thesis.” It’s what seniors commonly refer to as their final paper before graduation. That’s not what we’re talking about here. That type of thesis is a long, well-written paper that takes years to piece together.

Instead, we’re talking about a single sentence that ties together the main idea of any argument . In the context of student essays, it’s a statement that summarizes your topic and declares your position on it. This sentence can tell a reader whether your essay is something they want to read.

2 Categories of Thesis Statements: Informative and Persuasive

Just as there are different types of essays, there are different types of thesis statements. The thesis should match the essay.

For example, with an informative essay, you should compose an informative thesis (rather than argumentative). You want to declare your intentions in this essay and guide the reader to the conclusion that you reach.

To make a peanut butter and jelly sandwich, you must procure the ingredients, find a knife, and spread the condiments.

This thesis showed the reader the topic (a type of sandwich) and the direction the essay will take (describing how the sandwich is made).

Most other types of essays, whether compare/contrast, argumentative, or narrative, have thesis statements that take a position and argue it. In other words, unless your purpose is simply to inform, your thesis is considered persuasive. A persuasive thesis usually contains an opinion and the reason why your opinion is true.

Peanut butter and jelly sandwiches are the best type of sandwich because they are versatile, easy to make, and taste good.

In this persuasive thesis statement, you see that I state my opinion (the best type of sandwich), which means I have chosen a stance. Next, I explain that my opinion is correct with several key reasons. This persuasive type of thesis can be used in any essay that contains the writer’s opinion, including, as I mentioned above, compare/contrast essays, narrative essays, and so on.

2 Styles of Thesis Statements

Just as there are two different types of thesis statements (informative and persuasive), there are two basic styles you can use.

The first style uses a list of two or more points . This style of thesis is perfect for a brief essay that contains only two or three body paragraphs. This basic five-paragraph essay is typical of middle and high school assignments.

C.S. Lewis’s Chronicles of Narnia series is one of the richest works of the 20th century because it offers an escape from reality, teaches readers to have faith even when they don’t understand, and contains a host of vibrant characters.

In the above persuasive thesis, you can see my opinion about Narnia followed by three clear reasons. This thesis is perfect for setting up a tidy five-paragraph essay.

In college, five paragraph essays become few and far between as essay length gets longer. Can you imagine having only five paragraphs in a six-page paper? For a longer essay, you need a thesis statement that is more versatile. Instead of listing two or three distinct points, a thesis can list one overarching point that all body paragraphs tie into.

Good vs. evil is the main theme of Lewis’s Narnia series, as is made clear through the struggles the main characters face in each book.

In this thesis, I have made a claim about the theme in Narnia followed by my reasoning. The broader scope of this thesis allows me to write about each of the series’ seven novels. I am no longer limited in how many body paragraphs I can logically use.

Formula for a Strong Argumentative Thesis

One thing I find that is helpful for students is having a clear template. While students rarely end up with a thesis that follows this exact wording, the following template creates a good starting point:

___________ is true because of ___________, ___________, and ___________.

Conversely, the formula for a thesis with only one point might follow this template:

___________________ is true because of _____________________.

Students usually end up using different terminology than simply “because,” but having a template is always helpful to get the creative juices flowing.

The Qualities of a Solid Thesis Statement

When composing a thesis, you must consider not only the format, but other qualities like length, position in the essay, and how strong the argument is.

Length: A thesis statement can be short or long, depending on how many points it mentions. Typically, however, it is only one concise sentence. It does contain at least two clauses, usually an independent clause (the opinion) and a dependent clause (the reasons). You probably should aim for a single sentence that is at least two lines, or about 30 to 40 words long.

Position: A thesis statement always belongs at the beginning of an essay. This is because it is a sentence that tells the reader what the writer is going to discuss. Teachers will have different preferences for the precise location of the thesis, but a good rule of thumb is in the introduction paragraph, within the last two or three sentences.

Strength: Finally, for a persuasive thesis to be strong, it needs to be arguable. This means that the statement is not obvious, and it is not something that everyone agrees is true.

Example of weak thesis:

Peanut butter and jelly sandwiches are easy to make because it just takes three ingredients.

Most people would agree that PB&J is one of the easiest sandwiches in the American lunch repertoire.

Example of a stronger thesis:

Peanut butter and jelly sandwiches are fun to eat because they always slide around.

This is more arguable because there are plenty of folks who might think a PB&J is messy or slimy rather than fun.

Composing a thesis statement does take a bit more thought than many other parts of an essay. However, because a thesis statement can contain an entire argument in just a few words, it is worth taking the extra time to compose this sentence. It can direct your research and your argument so that your essay is tight, focused, and makes readers think.

How to Write a Strong Thesis Statement: 4 Steps + Examples

What’s Covered:

What is the purpose of a thesis statement, writing a good thesis statement: 4 steps, common pitfalls to avoid, where to get your essay edited for free.

When you set out to write an essay, there has to be some kind of point to it, right? Otherwise, your essay would just be a big jumble of word salad that makes absolutely no sense. An essay needs a central point that ties into everything else. That main point is called a thesis statement, and it’s the core of any essay or research paper.

You may hear about Master degree candidates writing a thesis, and that is an entire paper–not to be confused with the thesis statement, which is typically one sentence that contains your paper’s focus. 

Read on to learn more about thesis statements and how to write them. We’ve also included some solid examples for you to reference.

Typically the last sentence of your introductory paragraph, the thesis statement serves as the roadmap for your essay. When your reader gets to the thesis statement, they should have a clear outline of your main point, as well as the information you’ll be presenting in order to either prove or support your point. 

The thesis statement should not be confused for a topic sentence , which is the first sentence of every paragraph in your essay. If you need help writing topic sentences, numerous resources are available. Topic sentences should go along with your thesis statement, though.

Since the thesis statement is the most important sentence of your entire essay or paper, it’s imperative that you get this part right. Otherwise, your paper will not have a good flow and will seem disjointed. That’s why it’s vital not to rush through developing one. It’s a methodical process with steps that you need to follow in order to create the best thesis statement possible.

Step 1: Decide what kind of paper you’re writing

When you’re assigned an essay, there are several different types you may get. Argumentative essays are designed to get the reader to agree with you on a topic. Informative or expository essays present information to the reader. Analytical essays offer up a point and then expand on it by analyzing relevant information. Thesis statements can look and sound different based on the type of paper you’re writing. For example:

• Argumentative: The United States needs a viable third political party to decrease bipartisanship, increase options, and help reduce corruption in government.
• Informative: The Libertarian party has thrown off elections before by gaining enough support in states to get on the ballot and by taking away crucial votes from candidates.
• Analytical: An analysis of past presidential elections shows that while third party votes may have been the minority, they did affect the outcome of the elections in 2020, 2016, and beyond.

Step 2: Figure out what point you want to make

Once you know what type of paper you’re writing, you then need to figure out the point you want to make with your thesis statement, and subsequently, your paper. In other words, you need to decide to answer a question about something, such as:

• What impact did reality TV have on American society?
• How has the musical Hamilton affected perception of American history?
• Why do I want to major in [chosen major here]?

If you have an argumentative essay, then you will be writing about an opinion. To make it easier, you may want to choose an opinion that you feel passionate about so that you’re writing about something that interests you. For example, if you have an interest in preserving the environment, you may want to choose a topic that relates to that. 

If you’re writing your college essay and they ask why you want to attend that school, you may want to have a main point and back it up with information, something along the lines of:

“Attending Harvard University would benefit me both academically and professionally, as it would give me a strong knowledge base upon which to build my career, develop my network, and hopefully give me an advantage in my chosen field.”

Step 3: Determine what information you’ll use to back up your point

Once you have the point you want to make, you need to figure out how you plan to back it up throughout the rest of your essay. Without this information, it will be hard to either prove or argue the main point of your thesis statement. If you decide to write about the Hamilton example, you may decide to address any falsehoods that the writer put into the musical, such as:

“The musical Hamilton, while accurate in many ways, leaves out key parts of American history, presents a nationalist view of founding fathers, and downplays the racism of the times.”

Once you’ve written your initial working thesis statement, you’ll then need to get information to back that up. For example, the musical completely leaves out Benjamin Franklin, portrays the founding fathers in a nationalist way that is too complimentary, and shows Hamilton as a staunch abolitionist despite the fact that his family likely did own slaves. 

Step 4: Revise and refine your thesis statement before you start writing

Read through your thesis statement several times before you begin to compose your full essay. You need to make sure the statement is ironclad, since it is the foundation of the entire paper. Edit it or have a peer review it for you to make sure everything makes sense and that you feel like you can truly write a paper on the topic. Once you’ve done that, you can then begin writing your paper.

When writing a thesis statement, there are some common pitfalls you should avoid so that your paper can be as solid as possible. Make sure you always edit the thesis statement before you do anything else. You also want to ensure that the thesis statement is clear and concise. Don’t make your reader hunt for your point. Finally, put your thesis statement at the end of the first paragraph and have your introduction flow toward that statement. Your reader will expect to find your statement in its traditional spot.

If you’re having trouble getting started, or need some guidance on your essay, there are tools available that can help you.

What Is a Thesis Statement?

A thesis statement is typically one sentence that appears in the first paragraph of an essay that captures the essay's purpose. Think of the thesis statement as a one-sentence summary that tells the reader exactly what an essay says.

Rather than writing your essay like a puzzle, keeping the reader in suspense about what conclusion you'll reach by the end, use the thesis statement like a treasure map to give the reader a sense of your essay's direction. Tell them the conclusion up front, so they know where your piece is headed.

Once you've done your research and found your sources, craft a thesis statement that clearly indicates the direction your essay will take. As you write, think about how each paragraph connects to your thesis. If you're struggling to understand how a particular idea relates directly to the thesis statement, it may be a sign that you've diverged from the purpose of the essay.

THESIS STATEMENT DEFINITION

A thesis statement is a one-sentence declaration of intention — a summation of the main idea your essay will explain at length. An effective thesis statement will make a unique claim or seek to answer an important question.

Tips for Writing a Good Thesis Statement

Be specific.

Essays should be based on a specific argument. Check your thesis statement to see if the central idea of your writing is too vague. If you argue for something overly general — for example, an argument that all pop music is bad — your essay will try to conquer too many ideas and be unfocused.

Refine your argument to be more specific. Perhaps you'll say that pop music suffers from repetitive chord progressions or that pop songs have unimaginative lyrics. These narrower claims allow you to easily marshall evidence in support of your thesis.

Make a Clear Argument

Often, you need to write a paper within a very limited set of parameters — usually a few thousand words at most. Within a prescribed framework, you won't have space on the page to fully address multiple arguments.

If a reader can't ascertain the direction your essay will take from reading the thesis statement alone, then revise it to ensure your main point is stated plainly. If you're struggling to make your argument clear, try formulating your thesis statement using this template: "In this paper, I argue that __________."

Because some writing instructors forbid or disapprove of the first-person point of view in academic essays, you may have to change your thesis statement later; however, using this template reminds you what your argument should be, which is a helpful early drafting technique.

Take a Strong Stance

When writing your essay's thesis statement, ask whether it is a statement that can be argued with. For example, if your thesis statement is, "Computers are a popular technology in today's society," your essay might not be advancing a position so much as stating an objectively true fact.

Most essays will require you to take a stance, not make an observation, so craft a thesis statement that actually puts forward a unique perspective.

Question Your Assumptions

As you formulate the thesis statement of your essay, ask yourself what assumptions your argument is based on. In other words, what must your readers assume to be true before they can even begin to accept your argument?

Be particularly aware of your intended audience. For example, does your argument rely on a religious or moral code to prove that it is inherently right? If you are writing a paper for a class in Christian ministry, a dogmatic argument might be appropriate; for a sociology paper, however, such arguments don't hold water.

Think about the ways in which your argument may not hold up for people who don't subscribe to your viewpoints, then revise or re-approach your thesis statement so that your argument doesn't depend on those assumptions.

Don't Hide Your Thesis

Keep in mind that your thesis statement should come near the beginning of your essay. Conventional wisdom dictates that it should appear by the end of the first paragraph, though the exact positioning may vary, depending on how much introduction your specific essay requires. In any case, it should generally come at the end of your introduction to the material — the final statement your reader sees at the beginning, before moving into the body of your argument.

To some extent, it's also important not to overthink your thesis statement. Don't dress up a thesis statement with fancy language, and don't be too clever in how you set the stage for your argument; both of these strategies sometimes disguise a weak central thesis. Whoever your professor is, they will appreciate you getting to the point in a clear, concise manner.

Argumentative essays ask students to make the case for a particular perspective, or to persuade the reader to agree with the writer's point of view by the time they reach the essay's conclusion. In these essays, a thesis statement should be a clear picture of the argument you will make over the course of your essay.

In an American history class, you are asked to argue about the dominant cause of the War of 1812. Your thesis statement might look like, “The War of 1812 was a direct result of British arms sales to native tribes in the American West.”

In an ethics class, you are asked to argue about the moral obligation to help people in need. Your thesis statement might read, “By virtue of a social contract, we do have a moral obligation to help one another.”

Analytical Essay

In analytical essays, writers must communicate their interpretation of a given source or set of sources. In these essays, a thesis statement will explain the conclusion that your analysis has led you to. It may also be helpful to forecast your analysis by explaining which specific points you'll be examining. A helpful formula to get started with this kind of thesis statement is: "In this essay, I argue __________ by examining ____, ____, and ____."

In an English class, you've been asked to write an essay that analyzes how a persuasive article about climate change was constructed. Your thesis statement might say, “In this paper, I argue that Johnson relies too heavily on personal anecdotes and interviews, rather than scientific data, to establish the threat of climate change.”

In a psychology class, your assignment is an essay that analyzes the connection between depression and childhood trauma based on several studies you've researched. Your thesis statement might read, “Based on the data from these three studies, it's clear that there is a direct link between childhood trauma and clinical depression emerging in adults.”

Expository Essay

Expository essays ask writers to provide an informational breakdown of a topic, educating readers using specific details. It may be hard to understand how a thesis statement is of use in an expository essay because expository writing often does not advance an argument. Even so, a controlling statement near the beginning of the essay that summarizes your point is useful. By communicating clearly what the intention of your writing is, you can ensure that each new piece of information supports the central idea you are building.

A helpful formula for guiding your expository essay is: "In this essay, I will teach my reader __________." As you work toward this goal, you can revisit this sentence later and rework it into an effective thesis statement.

In a biochemistry class, you've been asked to write an essay explaining the impact of bisphenol A on the human body. Your thesis statement might say, “This essay will make clear the correlation between bisphenol A exposure and hypertension.”

In a gender studies class, you must write an essay that explains third-wave feminism. Your thesis statement might read, “Third-wave feminism built upon the work of earlier generations of feminists to advocate for an expanded view of what being a woman means.”

Personal Essay

Especially in composition and creative writing classes, you might be asked to write essays that draw upon your personal experiences. Prompts for personal essays might include writing about your experiences with race or your development as a writer, and these essays are often centered on a moment of realization or revelation. You can distill these themes into a thesis statement for your personal essay. While there may be no central argument in a thesis like this, there is always an organizing principle, such as change, destiny, growth, or irony.

In a creative writing class, you have to write an essay about how the place you grew up shaped you. Your thesis statement might look like, “Growing up on the farm taught me how to be more patient.”

In a composition class, you have to write an essay about the first time you realized how your gender was part of your identity. Your essay's thesis statement might read, “Because I was yelled at for playing with dolls as a kid, I understood that I didn't fit the narrow constraints of masculinity as my family defined it.”

Some Final Thoughts

Crafting an effective thesis statement is a useful exercise not just in college, but in your everyday life. It teaches you to examine ideas, organize them into a central theme or argument, and to persuasively mobilize evidence in support of this argument — a skill useful in many careers and personal endeavors.

25 Thesis Statement Examples That Will Make Writing a Breeze

Understanding what makes a good thesis statement is one of the major keys to writing a great research paper or argumentative essay. The thesis statement is where you make a claim that will guide you through your entire paper. If you find yourself struggling to make sense of your paper or your topic, then it's likely due to a weak thesis statement.

Let's take a minute to first understand what makes a solid thesis statement, and what key components you need to write one of your own.

A thesis statement always goes at the beginning of the paper. It will typically be in the first couple of paragraphs of the paper so that it can introduce the body paragraphs, which are the supporting evidence for your thesis statement.

Your thesis statement should clearly identify an argument. You need to have a statement that is not only easy to understand, but one that is debatable. What that means is that you can't just put any statement of fact and have it be your thesis. For example, everyone knows that puppies are cute . An ineffective thesis statement would be, "Puppies are adorable and everyone knows it." This isn't really something that's a debatable topic.

Something that would be more debatable would be, "A puppy's cuteness is derived from its floppy ears, small body, and playfulness." These are three things that can be debated on. Some people might think that the cutest thing about puppies is the fact that they follow you around or that they're really soft and fuzzy.

All cuteness aside, you want to make sure that your thesis statement is not only debatable, but that it also actually thoroughly answers the research question that was posed. You always want to make sure that your evidence is supporting a claim that you made (and not the other way around). This is why it's crucial to read and research about a topic first and come to a conclusion later. If you try to get your research to fit your thesis statement, then it may not work out as neatly as you think. As you learn more, you discover more (and the outcome may not be what you originally thought).

Additionally, your thesis statement shouldn't be too big or too grand. It'll be hard to cover everything in a thesis statement like, "The federal government should act now on climate change." The topic is just too large to actually say something new and meaningful. Instead, a more effective thesis statement might be, "Local governments can combat climate change by providing citizens with larger recycling bins and offering local classes about composting and conservation." This is easier to work with because it's a smaller idea, but you can also discuss the overall topic that you might be interested in, which is climate change.

So, now that we know what makes a good, solid thesis statement, you can start to write your own. If you find that you're getting stuck or you are the type of person who needs to look at examples before you start something, then check out our list of thesis statement examples below.

Thesis statement examples

A quick note that these thesis statements have not been fully researched. These are merely examples to show you what a thesis statement might look like and how you can implement your own ideas into one that you think of independently. As such, you should not use these thesis statements for your own research paper purposes. They are meant to be used as examples only.

• Vaccinations Because many children are unable to vaccinate due to illness, we must require that all healthy and able children be vaccinated in order to have herd immunity.
• Educational Resources for Low-Income Students Schools should provide educational resources for low-income students during the summers so that they don't forget what they've learned throughout the school year.
• School Uniforms School uniforms may be an upfront cost for families, but they eradicate the visual differences in income between students and provide a more egalitarian atmosphere at school.
• Populism The rise in populism on the 2016 political stage was in reaction to increasing globalization, the decline of manufacturing jobs, and the Syrian refugee crisis.
• Public Libraries Libraries are essential resources for communities and should be funded more heavily by local municipalities.
• Cyber Bullying With more and more teens using smartphones and social media, cyber bullying is on the rise. Cyber bullying puts a lot of stress on many teens, and can cause depression, anxiety, and even suicidal thoughts. Parents should limit the usage of smart phones, monitor their children's online activity, and report any cyber bullying to school officials in order to combat this problem.
• Medical Marijuana for Veterans Studies have shown that the use of medicinal marijuana has been helpful to veterans who suffer from Post-Traumatic Stress Disorder (PTSD). Medicinal marijuana prescriptions should be legal in all states and provided to these veterans. Additional medical or therapy services should also be researched and implemented in order to help them re-integrate back into civilian life.
• Work-Life Balance Corporations should provide more work from home opportunities and six-hour workdays so that office workers have a better work-life balance and are more likely to be productive when they are in the office.
• Teaching Youths about Consensual Sex Although sex education that includes a discussion of consensual sex would likely lead to less sexual assault, parents need to teach their children the meaning of consent from a young age with age appropriate lessons.
• Whether or Not to Attend University A degree from a university provides invaluable lessons on life and a future career, but not every high school student should be encouraged to attend a university directly after graduation. Some students may benefit from a trade school or a "gap year" where they can think more intensely about what it is they want to do for a career and how they can accomplish this.
• Studying Abroad Studying abroad is one of the most culturally valuable experiences you can have in college. It is the only way to get completely immersed in another language and learn how other cultures and countries are different from your own.
• Women's Body Image Magazines have done a lot in the last five years to include a more diverse group of models, but there is still a long way to go to promote a healthy woman's body image collectively as a culture.
• Cigarette Tax Heavily taxing and increasing the price of cigarettes is essentially a tax on the poorest Americans, and it doesn't deter them from purchasing. Instead, the state and federal governments should target those economically disenfranchised with early education about the dangers of smoking.
• Veganism A vegan diet, while a healthy and ethical way to consume food, indicates a position of privilege. It also limits you to other cultural food experiences if you travel around the world.
• University Athletes Should be Compensated University athletes should be compensated for their service to the university, as it is difficult for these students to procure and hold a job with busy academic and athletic schedules. Many student athletes on scholarship also come from low-income neighborhoods and it is a struggle to make ends meet when they are participating in athletics.
• Women in the Workforce Sheryl Sandberg makes a lot of interesting points in her best-selling book, Lean In , but she only addressed the very privileged working woman and failed to speak to those in lower-skilled, lower-wage jobs.
• Assisted Suicide Assisted suicide should be legal and doctors should have the ability to make sure their patients have the end-of-life care that they want to receive.
• Celebrity and Political Activism Although Taylor Swift's lyrics are indicative of a feminist perspective, she should be more politically active and vocal to use her position of power for the betterment of society.
• The Civil War The insistence from many Southerners that the South seceded from the Union for states' rights versus the fact that they seceded for the purposes of continuing slavery is a harmful myth that still affects race relations today.
• Blue Collar Workers Coal miners and other blue-collar workers whose jobs are slowly disappearing from the workforce should be re-trained in jobs in the technology sector or in renewable energy. A program to re-train these workers would not only improve local economies where jobs have been displaced, but would also lead to lower unemployment nationally.
• Diversity in the Workforce Having a diverse group of people in an office setting leads to richer ideas, more cooperation, and more empathy between people with different skin colors or backgrounds.
• Re-Imagining the Nuclear Family The nuclear family was traditionally defined as one mother, one father, and 2.5 children. This outdated depiction of family life doesn't quite fit with modern society. The definition of normal family life shouldn't be limited to two-parent households.
• Digital Literacy Skills With more information readily available than ever before, it's crucial that students are prepared to examine the material they're reading and determine whether or not it's a good source or if it has misleading information. Teaching students digital literacy and helping them to understand the difference between opinion or propaganda from legitimate, real information is integral.
• Beauty Pageants Beauty pageants are presented with the angle that they empower women. However, putting women in a swimsuit on a stage while simultaneously judging them on how well they answer an impossible question in a short period of time is cruel and purely for the amusement of men. Therefore, we should stop televising beauty pageants.
• Supporting More Women to Run for a Political Position In order to get more women into political positions, more women must run for office. There must be a grassroots effort to educate women on how to run for office, who among them should run, and support for a future candidate for getting started on a political career.

Still stuck? Need some help with your thesis statement?

If you are still uncertain about how to write a thesis statement or what a good thesis statement is, be sure to consult with your teacher or professor to make sure you're on the right track. It's always a good idea to check in and make sure that your thesis statement is making a solid argument and that it can be supported by your research.

After you're done writing, it's important to have someone take a second look at your paper so that you can ensure there are no mistakes or errors. It's difficult to spot your own mistakes, which is why it's always recommended to have someone help you with the revision process, whether that's a teacher, the writing center at school, or a professional editor such as one from ServiceScape .

The Ultimate Guide to Writing a Thesis Statement

A thesis statement is a sentence in a paper or essay (in the opening paragraph) that introduces the main topic to the reader. As one of the first things your reader sees, your thesis statement is one of the most important sentences in your entire paper—but also one of the hardest to write! 

In this article, we explain how to write a thesis statement in the best way possible. We look at what to include and the steps to take for writing your own, along with plenty of thesis statement examples to guide you.

What is a thesis statement, how to write a thesis statement: basics, what to include in a thesis statement (with examples), how to write a thesis statement in 3 steps.

The goal of a thesis statement is to let your reader know what your paper or essay is about. It helps your reader understand the greater context and scope of your topic, plus it lets your readers know what to expect from the rest of the work. 

A secondary benefit of a thesis statement is that it makes it easier to search for papers on a particular topic, especially in the realm of academic writing like research papers and thesis papers (which are sometimes known as dissertations when written for doctoral degrees). For example, if you’re writing a paper of your own, you’ll want to look up other papers to use as evidence and sources . You can simply scan the thesis statements of several papers to see which match your topic and could be worthwhile sources to cite. 

Before we get into details, here are the basic steps for how to write a thesis statement: 

• Develop the best topic to cover in your paper
• Phrase your topic as a question-and-answer
• Add some polish

We ’ ll describe each of those steps in more detail below, but we wanted to share a quick guide. Also, we ’ ll provide some thesis statement examples and talk about how to write a thesis statement for different kinds of essays: persuasive, compare-and-contrast, expository, and argumentative essays.

The thesis statement is located at the beginning of a paper, in the opening paragraph, making it an essential way to start an essay . A thesis statement isn’t necessarily the first sentence in an essay; typically you’ll want to hook the reader in an engaging way in the opening sentence before inserting your central idea or argument later in the first paragraph. A thesis statement is often confused with a topic sentence , the first sentence in a paragraph, because they both introduce the central idea of what follows. You can think of thesis statements as the topic sentence of your entire paper.  

Thesis statements are a necessary part of paper and essay writing , but different formats have different rules and best practices. Below, we break down how to write a thesis statement for the most common types of papers. 

How to write a thesis statement for expository and argumentative essays

Expository and argumentative essays are some of the most common types of academic papers. Because they don’t have a formal abstract like research papers, they rely on their thesis statements to provide an overview of what’s discussed. 

Thesis statements for argumentative and expository essays should use strong and decisive language; don’t be wishy-washy or uncertain. You want to take a stand right in the opening so that your readers understand what your paper is trying to show. 

Moreover, thesis statements for these essays should be specific, with some minor details to hint at the rest of the paper. It’s not enough to merely make your point; you also want to provide some basic evidence or background context to paint a full picture. 

If your paper dives into different subtopics or categories, try to fit them into the thesis statement if you can. You don’t have to get into details here, but it’s nice to mention the different sections at the top so that the reader knows what to expect. 

Thesis statement examples

Despite the taboo, insects make an excellent food source and could stem humanity’s looming food shortage, based on both their protein output and the sustainability of farming them. 

The backlash to rock ’n’ roll music in the ’50s by religious groups and traditionalists actually boosted the genre’s popularity instead of diminishing it as intended.

How to write a thesis statement for persuasive essays

Similar to argumentative essays, persuasive essays follow many of the same guidelines for their thesis statements: decisive language, specific details, and mentions of subtopics. 

However, the main difference is that, while the thesis statements for argumentative and expository essays state facts, the thesis statements for persuasive essays state clear opinions . Still, the format is the same, and the opinions are often treated like facts, including conclusive language and citing evidence to support your claims. 

Furthermore, unlike with other essays, it’s appropriate to make emotional connections in a thesis statement in persuasive essays. This can actually be a clever strategy to start your essay off on a more personal, impactful note. 

Advertising should not be allowed in public schools because it’s a distraction from studies and may lead to misguided priorities among the school board, to say nothing of the materialist culture it promotes. 

Exotic pets provide the same love and companionship as conventional pets, so the laws regulating which animals can and cannot be kept as pets should be more relaxed.

How to write a thesis statement for compare-and-contrast essays

Thesis statements for compare-and-contrast essays are tricky because you have at least two topics to touch on instead of just one. The same general guidelines apply (decisive language, details, etc.), but you need to give equal attention to both your topics—otherwise, your essay will seem biased from the start. 

As always, your thesis statement should reflect what’s written in the rest of your essay. If your essay spends more time comparing than contrasting, your thesis statement should focus more on similarities than differences. 

It sometimes helps to give specific examples as well, but keep them simple and brief. Save the finer details for the body of your essay. 

Sean Connery and Daniel Craig are the two most popular actors to portray James Bond, but both have their own distinct and at times contradictory interpretations of the character. 

Now that you know what you’re aiming for, it’s time to sit down and write your own thesis statement. To keep you on track, here are three easy steps to guide you. 

1 Brainstorm the best topic for your essay

You can’t write a thesis statement until you know what your paper is about, so your first step is choosing a topic. 

If the topic is already assigned, great ! That’s all for this step. If not, consider the tips below for choosing the topic that’s best for you:

• Pick a topic that you’re passionate about. Even if you don’t know much about it, it’ll be easier to learn about it while writing if you’re genuinely interested. 
• Narrow down your topic to something specific; otherwise, your paper will be too broad and perhaps too long. Just make sure it’s not too specific, or you won’t have enough to write about. Try to find a happy medium. 
• Check beforehand that there are enough strong, credible sources to use for research. You don’t want to run out of referential material halfway through. 

Once you’ve chosen a topic—and the angle or stance you want to take—then it’s time to put the idea for your thesis sentence into words. 

2 Phrase your topic as a question and then answer it

It’s not always easy to fit your entire thesis into just one sentence, let alone one that’s written clearly and eloquently. Here’s a quick technique to help you get started. 

First, phrase your topic as a question. For example, if you want to write about Mahatma Gandhi’s legacy, ask yourself, “What influences did Gandhi have on society after his death?” 

If you already know the answer, write it down—that’s a good start for your thesis statement. If you don’t know the answer, do some preliminary research to find out; you can certainly use what you discover as evidence and sources in your essay’s body paragraphs . 

3 Add some polish

Chances are, your first attempt at a thesis statement won’t be perfect. To get it to its best, try revising , editing , and adding what’s missing. 

Remember the core traits for thesis statements we mentioned above: decisive language, a happy medium of specific but not too specific details, and mention of subtopics. If you’re struggling to contain everything in a single sentence, feel free to move the secondary information to the following sentence. The thesis statement itself should only have what’s most necessary. 

If you’re in doubt, read your thesis statement to a friend and ask them what they think your paper is about. If they answer correctly, your thesis statement does its job. 

Next comes the hard part—writing the rest! While the bulk of the writing lies ahead, at least you’ve nailed down your central idea. To plot out your supporting argument, follow our advice on essay structure and let your ideas flow. 

PHYSICS INSPIRED AI-DRIVEN PHOTONIC INVERSE DESIGN FOR HIGH-PERFORMANCE PHOTONIC DEVICES

This thesis presents novel methodologies to integrate AI-driven and physics-inspired methodologies into photonic inverse design, setting new benchmarks for high-performance photonic devices in different branches of photonics. By blending advanced computational techniques with the foundational principles of electromagnetism, this research tackles key challenges in optimizing device efficiency, robustness, and functionality. The aim is to propel photonic technology beyond its current capabilities, offering transformative solutions for a range of novel applications.

The first major contribution focuses on adjoint-based topology optimization for on-chip single-photon coupling. We developed an adjoint topology optimization scheme to design high-efficiency couplers between photonic waveguides and single-photon sources (SPSs) in hexagonal boron nitride (hBN). This algorithm addresses fabrication constraints and SPS location uncertainties, achieving a remarkable average coupling efficiency of 78%. A library of designs is generated for different positions of the hBN flake containing an SPS relative to a silicon nitride (SiN) waveguide. These designs are then analyzed using dimensionality reduction techniques to investigate the relationship between device geometry and performance, infusing the design process with deep physical intuition and insight.

The second key advancement is presented through a neural network-based inverse design framework specifically developed for optimizing single-material, variable-index multilayer films. This neural network-driven technique, supported by a differentiable analytical solver, enables the realistic design and fabrication of these multilayer films, achieving high performance under ideal conditions. The approach also addresses the challenge of bridging the gap between these ideal designs and practical devices, which are subject to growth-related imperfections. By incorporating simulated systematic and random errors—reflecting actual deposition challenges—into the optimization process, we demonstrate that the neural network, initially trained to produce the ideal device, can be reconfigured to create designs that compensate for systematic deposition errors. This method remains effective even when random fabrication inconsistencies are present. The results provide a practical and experimentally viable strategy for developing single-material multilayer film stacks, ensuring reliable performance across a wide range of real-world applications.

The final cornerstone of this research investigates the two-stage inverse design of superchiral dielectric metasurfaces. We propose a two-stage inverse design scheme for dielectric lossless metasurfaces with central superchiral hot spots. By leveraging the excitation of high-quality factor modes with low mode volumes, we achieve up to 19,000-fold enhancements of optical chirality. This method extends the local density of field enhancements for non-chiral fields into the chiral regime and significantly surpasses previous enhancements in superchiral field generation. Our results open new avenues in chiral spectroscopy and chiral quantum photonics, exemplifying the powerful synergy of AI techniques and physics-based design principles in creating highly innovative and functional photonic structures.

Collectively, the methodologies developed in this thesis signify a major advancement in the field of photonic inverse design. By merging AI-driven techniques with rigorous physics-based optimization frameworks, this research paves the way for the next generation of photonic devices.
