What Is a Thesis? | Ultimate Guide & Examples

Published on September 14, 2022 by Tegan George . Revised on April 16, 2024.

A thesis is a type of research paper based on your original research. It is usually submitted as the final step of a master’s program or a capstone to a bachelor’s degree.

Writing a thesis can be a daunting experience. Other than a dissertation , it is one of the longest pieces of writing students typically complete. It relies on your ability to conduct research from start to finish: choosing a relevant topic , crafting a proposal , designing your research , collecting data , developing a robust analysis, drawing strong conclusions , and writing concisely .

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.

Prevent plagiarism. Run a free check.

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.

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.

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 .

About Thesis Statements

Qualities of a thesis statement.

Thesis statements:

state the subject matter and main ideas of a paper.
appear in the first paragraph and announces what you will discuss in your paper.
define the scope and focus of your essay, and tells your reader what to expect.
are not a simple factual statement. It is an assertion that states your claims and that you can prove with evidence.
should be the product of research and your own critical thinking.
can be very helpful in constructing an outline for your essay; for each point you make, ask yourself whether it is relevant to the thesis.

Steps you can use to create a thesis statement

1. Start out with the main topic and focus of your essay.

youth gangs + prevention and intervention programs

2. Make a claim or argument in one sentence. It can be helpful to start with a question which you then turn into an argument

Can prevention and intervention programs stop youth gang activities? How? ►►► "Prevention and intervention programs can stop youth gang activities by giving teens something else to do."

3. Revise the sentence by using specific terms.

"Early prevention programs in schools are the most effective way to prevent youth gang involvement by giving teens good activities that offer a path to success."

4. Further revise the sentence to cover the scope of your essay and make a strong statement.

"Among various prevention and intervention efforts that have been made to deal with the rapid growth of youth gangs, early school-based prevention programs are the most effective way to prevent youth gang involvement, which they do by giving teens meaningful activities that offer pathways to achievement and success."

5. Keep your thesis statement flexible and revise it as needed. In the process of researching and writing, you may find new information or refine your understanding of the topic.

You can view this short video for more tips on how to write a clear thesis statement.

An outline is the skeleton of your essay, in which you list the arguments and subtopics in a logical order. A good outline is an important element in writing a good paper. An outline helps to target your research areas, keep you within the scope without going off-track, and it can also help to keep your argument in good order when writing the essay. Once your outline is in good shape, it is much easier to write your paper; you've already done most of the thinking, so you just need to fill in the outline with a paragraph for each point.

To write an outline: The most common way to write an outline is the list format. List all the major topics and subtopics with the key points that support them. Put similar topics and points together and arrange them in a logical order. Include an introduction, a body, and a conclusion.

A list outline should arrange the main points or arguments in a hierarchical structure indicated by Roman numerals for main ideas (I, II, III...), capital letters for subtopics (A, B, C...), Arabic numerals for details (1,2,3...), and lower-case letters for fine details if needed (a,b,c...). This helps keep things organized.

Here is a shortened example of an outline:

Introduction: background and thesis statement

I. First topic

1. Supporting evidence 2. Supporting evidence

II. Second Topic

III. Third Topic

I. Summarize the main points of your paper II. Restate your thesis in different words III. Make a strong final statement

What is a Thesis Statement and How to Write It (with Examples)

A thesis statement is basically a sentence or two that summarizes the central theme of your research. In research papers and essays, it is typically placed at the end of the introduction section, which provides broad knowledge about the investigation/study. To put it simply, the thesis statement can be thought of as the main message of any film, which is communicated through the plot and characters. Similar to how a director has a vision, the author(s) in this case has an opinion on the subject that they wish to portray in their research report.

In this article, we will provide a thorough overview on thesis statements, addressing the most frequently asked questions, including how authors arrive at and create a thesis statement that effectively summarizes your research. To make it simpler, we’ve broken this information up into subheadings that focus on different aspects of writing the thesis statement.

What is a thesis statement?

A thesis statement, in essence, is a sentence that summarizes the main concept the author(s) wishes to investigate in their research. A thesis statement is often a “question/hypothesis” the author(s) wants to address, using a certain methodology or approach to provide sufficient evidence to support their claims and findings. However, it isn’t necessarily the topic sentence (first sentence) in a research paper introduction, which could be a general statement.

Returning to our movie analogy, a thesis statement is comparable to the particular viewpoint a director wants to convey to his audience. A thesis statement tells the reader the fundamental idea of the study and the possible course it will take to support that idea. A well-structured thesis statement enables the reader to understand the study and the intended approach, so both its placement and clarity matter here. An appropriately placed thesis statement, usually at the end of an introductory paragraph, ensures the reader will not lose interest. A thesis statement plays another crucial role, it summarizes the main idea behind the study so that readers will understand the question the author is trying to answer. It gives the reader some background information and a sense of the topic’s wider context while also hinting at the work or experimental approach that will come next. To summarize, thesis statements are generally that one key phrase you skim over to rapidly understand the thesis of a study.

What should a thesis statement include (with examples)?

Now that we have understood the concept, the next step is learning how to write a good thesis statement. A strong thesis statement should let the reader understand how well-versed you are, as an author, in the subject matter of the study and your position on the topic at hand. The elements listed below should be considered while crafting a statement for your thesis or paper to increase its credibility and impact.

The author should take a position that a sizable portion of the readership may disagree with. The subject should not be a well-known, well-defined issue with just unanimity of view. This form of thesis statement is typically viewed as weak because it implies that there is nothing substantial to investigate and demonstrate. To pique readers’ interest, the thesis statement should be debatable in some way, and the findings should advance the body of knowledge.
A review of pertinent literature on the subject is a must in order for the author to establish an informed opinion about the questions they wish to pose and the stance they would want to take during their study, this is the basis to develop a strong thesis statement. The authors of the study should be able to support their statements with relevant research, strengthening their stance by citing literature.
The thesis statement should highlight just one main idea, with each claim made by the authors in the paper demonstrating the accuracy of the statement. Avoid multiple themes running throughout the article as this could confuse readers and undermine the author’s perspective on the subject. It can also be a sign of the authors’ ambiguity.
The main objective of a thesis statement is to briefly describe the study’s conclusion while posing a specific inquiry that clarifies the author’s stance or perspective on the subject. Therefore, it is crucial to clearly establish your viewpoint in the statement.

Based on the considerations above, you may wonder how to write a thesis statement for different types of academic essays. Expository and argumentative essays, the most common types of essays, both call for a statement that takes a stand on the issue and uses powerful language. These kinds of thesis statements need to be precise and contain enough background material to give a comprehensive picture of the subject. However, in persuasive essays, which typically integrate an emotive perspective and personal experiences, the opinions are presented as facts that need supporting evidence. The sole difference between argumentative and expository essays and persuasive essays is that the former require the use of strong viewpoints, while the latter does not. Last but not least, the thesis statement for a compare-and-contrast essay addresses two themes rather than just one. Authors can choose to concentrate more on examining similarities or differences depending on the nature of the study; the only caveat is that both topics must receive equal attention to prevent biases.

How to write a thesis statement in four steps?

Coming up with a research question might be challenging in situations when the research topic is not decided or it’s a new field of study. You may want to delve deeper into a widely researched subject, continue with your current research, or pursue a topic you are passionate about. If you don’t have a thesis statement yet, here are four easy stages to get you started.

Start with a working thesis statement : Writing the statement is not so straightforward; you won’t magically write the final thesis statement at once. It is preferable to choose an initial working thesis after reviewing relevant literature on the topic. Once you have chosen a subject that interests you, attempt to think of a specific query that has not been raised or that would be fascinating to contribute to the body of literature. For example, if you are writing an article or paper about ChatGPT, you could want to look into how ChatGPT affects learning among students. You can even get more specific, like, “How does ChatGPT harm learning and education?”
Outline your answer (your positioning on the subject): Based on your review of past research, you would form an opinion about the subject—in this example, the effect of ChatGPT on students’ learning—and then you write down your tentative answer to this question. If your initial response is that ChatGPT use has a detrimental impact on education and learning, this would serve as the foundation for your research. Your study would include research and findings to support this assertion and persuade the reader to accept your hypothesis.
Provide evidence to support your claim : The goal of your study should be to back your hypothesis with enough evidence, relevant facts and literature, to support your claim and explain why you selected that particular response (in this case, why you believe that ChatGPT has a negative impact on learning and education). The focus should be on discussing both the benefits and drawbacks of using ChatGPT and demonstrating why the disadvantages outweigh the benefits. An argumentative thesis statement example on the same topic would be that, despite ChatGPT’s enormous potential as a virtual learning tool for students, it has a detrimental effect on their creativity and critical thinking skills and encourages problematic behaviors like cheating and plagiarism.
Polish your thesis statement: After outlining your initial statement, improve it by keeping these three elements in mind.
Does it make it clear what position you hold on the subject?
Does it effectively connect the various facets of the study topic together?
Does it summarize the key points of your narrative?

The thesis statement will also gain from your comments on the approach you will employ to validate your claim. For example, the aforementioned thesis statement may be clarified as “Although ChatGPT has enormous potential to serve as a virtual tutor for students and assistant to instructors, its disadvantages, such as plagiarism and the creation of false information, currently outweigh the advantages.” This particular illustration offers a thoughtful discussion of the subject, enabling the author to make their case more persuasively.

How to generate a thesis statement?

No matter how complicated, any thesis or paper may be explained in one or two sentences. Just identify the question your research aims to answer, then write a statement based on your anticipated response. An effective thesis statement will have the following characteristics:

It should have a take on the subject (which is contentious/adds to existing knowledge)
It should express a main topic (other themes should only be included if they connect to the main theme)
It should declare your conclusion about the issue
It should be based on an objective, broad outlook on the subject.

To understand how to write a thesis statement from scratch, let’s use an example where you may want to learn about how mental and physical health are related.

Since the subject is still broad, you should first conduct a brainstorming session to acquire further thoughts. After reading literature, you determine that you are curious to learn how yoga enhances mental health. To develop a compelling thesis statement, you must further narrow this topic by posing precise questions that you can answer through your research. You can ask, “How does yoga affect mental health. What is the possible mean”? This topic makes it plain to the reader what the study is about but it is necessary for you to adopt a position on the issue. Upon further deliberation, the premise can be rephrased as “Yoga, a low impact form of exercise, positively impacts people’s mental health by lowering stress hormones and elevating healthy brain chemicals.” This clearly states your position on the topic. Finally, you may further develop this into a clear, precise thesis statement that asks, “Does practicing yoga induce feel-good hormones and lower the stress hormone, cortisol, that positively affects people’s mental health?” to turn it into a study.

Types of thesis statements?

The three primary categories of thesis statements are analytical, expository, and argumentative. You choose one over the other depending on the subject matter of your research or essay. In argumentative thesis statements, the author takes a clear stand and strives to persuade the reader of their claims, for example, “Animal agriculture is the biggest driver of climate change.” It is specific, concise, and also contentious. On the other hand, the purpose of an expository thesis statement is to interpret, assess, and discuss various facets of a subject. Here you shortlist the key points of your interpretation, and state the conclusion based on the interpretation you drew from the study. An analytical thesis statement aims to discuss, glean information on the subject, and explain the facts of the topic. Here, the goal is to critically analyze and summarize the points you will cover in the study.

Key takeaways

A good thesis statement summarizes the central idea of your thesis or research paper.
It serves as a compass to show the reader what the research will contend and why.
Before creating a thesis statement, keep in mind that the statement should be specific, coherent, and controversial.

Frequently asked questions (FAQs)

A thesis statement can be defined as a sentence that describes the main idea of the research or thesis to inform the reader of the argument the research will pursue and the reason the author adopts a specific stance on the subject. Essentially, it expresses the author’s judgment or opinion based on a review of the literature or personal research experience.

Any academic essay or research piece must have a thesis statement since it directs the research and attracts the reader’s attention to the main idea of the subject under discussion. In addition to confining the author to a specific subject, so they don’t veer off topic, it also enables the reader to understand the topic at hand and what to expect.

To create an impactful thesis statement, simply follow these four easy steps. Start by creating a working statement by posing the question that your research or thesis will attempt to answer. Then, outline your initial response and choose your position on the matter. Next, try to substantiate your claim with facts or other relevant information. Finally, hone your final thesis statement by crafting a cogent narrative using knowledge gained in the previous step.

Ideally the thesis statement should be placed at the end of an introduction of the paper or essay. Keep in mind that it is different from the topic sentence, which is more general.

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

tells the reader how you will interpret the significance of the subject matter under discussion.
is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
directly answers the question asked of you. A thesis is an interpretation of a question or 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.
makes a claim that others might dispute.
is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
Does my thesis pass the “So what?” test? If a reader’s first response is likely to be “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? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

Do I answer the question? Yes!
Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

A thesis statement provides the foundation for your entire research paper or essay. This statement is the central assertion that you want to express in your essay. A successful thesis statement is one that is made up of one or two sentences clearly laying out your central idea and expressing an informed, reasoned answer to your research question.

Usually, the thesis statement will appear at the end of the first paragraph of your paper. There are a few different types, and the content of your thesis statement will depend upon the type of paper you’re writing.

Key Takeaways: Writing a Thesis Statement

A thesis statement gives your reader a preview of your paper's content by laying out your central idea and expressing an informed, reasoned answer to your research question.
Thesis statements will vary depending on the type of paper you are writing, such as an expository essay, argument paper, or analytical essay.
Before creating a thesis statement, determine whether you are defending a stance, giving an overview of an event, object, or process, or analyzing your subject

Expository Essay Thesis Statement Examples

An expository essay "exposes" the reader to a new topic; it informs the reader with details, descriptions, or explanations of a subject. If you are writing an expository essay , your thesis statement should explain to the reader what she will learn in your essay. For example:

The United States spends more money on its military budget than all the industrialized nations combined.
Gun-related homicides and suicides are increasing after years of decline.
Hate crimes have increased three years in a row, according to the FBI.
Post-traumatic stress disorder (PTSD) increases the risk of stroke and arterial fibrillation (irregular heartbeat).

These statements provide a statement of fact about the topic (not just opinion) but leave the door open for you to elaborate with plenty of details. In an expository essay, you don't need to develop an argument or prove anything; you only need to understand your topic and present it in a logical manner. A good thesis statement in an expository essay always leaves the reader wanting more details.

Types of Thesis Statements

Before creating a thesis statement, it's important to ask a few basic questions, which will help you determine the kind of essay or paper you plan to create:

Are you defending a stance in a controversial essay ?
Are you simply giving an overview or describing an event, object, or process?
Are you conducting an analysis of an event, object, or process?

In every thesis statement , you will give the reader a preview of your paper's content, but the message will differ a little depending on the essay type .

Argument Thesis Statement Examples

If you have been instructed to take a stance on one side of a controversial issue, you will need to write an argument essay . Your thesis statement should express the stance you are taking and may give the reader a preview or a hint of your evidence. The thesis of an argument essay could look something like the following:

Self-driving cars are too dangerous and should be banned from the roadways.
The exploration of outer space is a waste of money; instead, funds should go toward solving issues on Earth, such as poverty, hunger, global warming, and traffic congestion.
The U.S. must crack down on illegal immigration.
Street cameras and street-view maps have led to a total loss of privacy in the United States and elsewhere.

These thesis statements are effective because they offer opinions that can be supported by evidence. If you are writing an argument essay, you can craft your own thesis around the structure of the statements above.

Analytical Essay Thesis Statement Examples

In an analytical essay assignment, you will be expected to break down a topic, process, or object in order to observe and analyze your subject piece by piece. Examples of a thesis statement for an analytical essay include:

The criminal justice reform bill passed by the U.S. Senate in late 2018 (" The First Step Act ") aims to reduce prison sentences that disproportionately fall on nonwhite criminal defendants.
The rise in populism and nationalism in the U.S. and European democracies has coincided with the decline of moderate and centrist parties that have dominated since WWII.
Later-start school days increase student success for a variety of reasons.

Because the role of the thesis statement is to state the central message of your entire paper, it is important to revisit (and maybe rewrite) your thesis statement after the paper is written. In fact, it is quite normal for your message to change as you construct your paper.

A thesis statement is a declarative sentence that asserts the position a paper will be taking. This statement should be both specific and arguable. Generally, the thesis statement will be placed at the end of the first paragraph of your paper. The remainder of your paper will support this thesis.

After you've landed on a satisfactory topic, your next step will be to solidify the position you would like to take and write a clear and succinct thesis statement which will lay the foundation for the rest of your paper.

For the sake of example, let's say that you've chosen to argue the merits of eating locally grown foods. You want to focus on the positive effects that this will have on one's health, the local economy, and on global ecology. You also want to dispel the myth that eating locally is more expensive, and therefore, the exclusive purview of the upper middle class.

An example of a thesis statement outlining your position might look like this:

The locavore movement that has gained popularity in the United States over the past several years offers a way to increase health, support the local economy, and promote global ecology by making some simple changes to the way that you and your family eat. Although frequently criticized for being far more expensive than eating factory-farmed foods, the truth is that the costs of home gardening and the prices for which you can purchase food at your local farmer's market are often far less expensive alternatives than buying from a chain grocer, not to mention safer and more nutritious.

Think of yourself as a member of a jury, listening to a lawyer who is presenting an opening argument. You'll want to know very soon whether the lawyer believes the accused to be guilty or not guilty, and how the lawyer plans to convince you. Readers of academic essays are like jury members: before they have read too far, they want to know what the essay argues as well as how the writer plans to make the argument. After reading your thesis statement, the reader should think, "This essay is going to try to convince me of something. I'm not convinced yet, but I'm interested to see how I might be."

An effective thesis cannot be answered with a simple "yes" or "no." A thesis is not a topic; nor is it a fact; nor is it an opinion. "Reasons for the fall of communism" is a topic. "Communism collapsed in Eastern Europe" is a fact known by educated people. "The fall of communism is the best thing that ever happened in Europe" is an opinion. (Superlatives like "the best" almost always lead to trouble. It's impossible to weigh every "thing" that ever happened in Europe. And what about the fall of Hitler? Couldn't that be "the best thing"?)

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.

Steps in Constructing a Thesis

First, analyze your primary sources. Look for tension, interest, ambiguity, controversy, and/or complication. Does the author contradict himself or herself? Is a point made and later reversed? What are the deeper implications of the author's argument? Figuring out the why to one or more of these questions, or to related questions, will put you on the path to developing a working thesis. (Without the why, you probably have only come up with an observation—that there are, for instance, many different metaphors in such-and-such a poem—which is not a thesis.)

Once you have a working thesis, write it down. There is nothing as frustrating as hitting on a great idea for a thesis, then forgetting it when you lose concentration. And by writing down your thesis you will be forced to think of it clearly, logically, and concisely. You probably will not be able to write out a final-draft version of your thesis the first time you try, but you'll get yourself on the right track by writing down what you have.

Keep your thesis prominent in your introduction. A good, standard place for your thesis statement is at the end of an introductory paragraph, especially in shorter (5-15 page) essays. Readers are used to finding theses there, so they automatically pay more attention when they read the last sentence of your introduction. Although this is not required in all academic essays, it is a good rule of thumb.

Anticipate the counterarguments. Once you have a working thesis, you should think about what might be said against it. This will help you to refine your thesis, and it will also make you think of the arguments that you'll need to refute later on in your essay. (Every argument has a counterargument. If yours doesn't, then it's not an argument—it may be a fact, or an opinion, but it is not an argument.)

This statement is on its way to being a thesis. However, it is too easy to imagine possible counterarguments. For example, a political observer might believe that Dukakis lost because he suffered from a "soft-on-crime" image. If you complicate your thesis by anticipating the counterargument, you'll strengthen your argument, as shown in the sentence below.

Some Caveats and Some Examples

A thesis is never a question. Readers of academic essays expect to have questions discussed, explored, or even answered. A question ("Why did communism collapse in Eastern Europe?") is not an argument, and without an argument, a thesis is dead in the water.

A thesis is never a list. "For political, economic, social and cultural reasons, communism collapsed in Eastern Europe" does a good job of "telegraphing" the reader what to expect in the essay—a section about political reasons, a section about economic reasons, a section about social reasons, and a section about cultural reasons. However, political, economic, social and cultural reasons are pretty much the only possible reasons why communism could collapse. This sentence lacks tension and doesn't advance an argument. Everyone knows that politics, economics, and culture are important.

A thesis should never be vague, combative or confrontational. An ineffective thesis would be, "Communism collapsed in Eastern Europe because communism is evil." This is hard to argue (evil from whose perspective? what does evil mean?) and it is likely to mark you as moralistic and judgmental rather than rational and thorough. It also may spark a defensive reaction from readers sympathetic to communism. If readers strongly disagree with you right off the bat, they may stop reading.

An effective thesis has a definable, arguable claim. "While cultural forces contributed to the collapse of communism in Eastern Europe, the disintegration of economies played the key role in driving its decline" is an effective thesis sentence that "telegraphs," so that the reader expects the essay to have a section about cultural forces and another about the disintegration of economies. This thesis makes a definite, arguable claim: that the disintegration of economies played a more important role than cultural forces in defeating communism in Eastern Europe. The reader would react to this statement by thinking, "Perhaps what the author says is true, but I am not convinced. I want to read further to see how the author argues this claim."

A thesis should be as clear and specific as possible. Avoid overused, general terms and abstractions. For example, "Communism collapsed in Eastern Europe because of the ruling elite's inability to address the economic concerns of the people" is more powerful than "Communism collapsed due to societal discontent."

How to Write a Thesis Statement for a Science Report

A science report is generally completed after you do a scientific test or experiment of some sort. The thesis of the science report basically relates to what your hypothesis was before you began the experiment. The hypothesis is the question that you plan to answer or what you plan to prove. Before you start the experiment, you need to articulate your hypothesis. Once you complete the experiment, the hypothesis will be turned into the thesis.

Figure out the purpose of your science report. Most are based on an experiment or test that was conducted. In this case, take the purpose from your hypothesis. Your hypothesis basically states the overall purpose you had for the experiment, such as attempting to prove that training dogs using positive reinforcement is more effective than negative reinforcement.

Write down the conclusions of your scientific test or experiment. These conclusions will be used in your overall science report and they will help you write the thesis statement. Your conclusions from the above example might include that positive reinforcement is a more effective training method for dogs than negative reinforcement, that praise and attention alone worked more often than treats alone, but combining the two was most effective of all.

Turn your hypothesis and conclusions into the thesis statement for your science report. With the above example, the first draft of your thesis statement might be, “Positive reinforcement has been proven to be a more effective method of dog training than negative reinforcement.”

Add even more details to your thesis statement. The more details you can add, the stronger the statement will be. For example, you could add the types of training methods you were comparing, along with which types of reinforcement worked best, to get the following thesis statement: “While comparing positive reinforcement and negative reinforcement as methods of dog training, it was found that the most effective training method is using positive reinforcement with a combination of treats and praise from the dog’s owner.”

What Makes a Thesis Statement Spectacular? — 5 things to know

Table of Contents

What Is a Thesis Statement?

A thesis statement is a declarative sentence that states the primary idea of an essay or a research paper . In this statement, the authors declare their beliefs or what they intend to argue in their research study. The statement is clear and concise, with only one or two sentences.

Thesis Statement — An Essential in Thesis Writing

A thesis statement distills the research paper idea into one or two sentences. This summary organizes your paper and develops the research argument or opinion. The statement is important because it lets the reader know what the research paper will talk about and how the author is approaching the issue. Moreover, the statement also serves as a map for the paper and helps the authors to track and organize their thoughts more efficiently.

A thesis statement can keep the writer from getting lost in a convoluted and directionless argument. Finally, it will also ensure that the research paper remains relevant and focused on the objective.

Where to Include the Thesis Statement?

The thesis statement is typically placed at the end of the introduction section of your essay or research paper. It usually consists of a single sentence of the writer’s opinion on the topic and provides a specific guide to the readers throughout the paper.

6 Steps to Write an Impactful Thesis Statement

Step 1 – analyze the literature.

Identify the knowledge gaps in the relevant research paper. Analyze the deeper implications of the author’s research argument. Was the research objective mentioned in the thesis statement reversed later in the discussion or conclusion? Does the author contradict themselves? Is there a major knowledge gap in creating a relevant research objective? Has the author understood and validated the fundamental theories correctly? Does the author support an argument without having supporting literature to cite? Answering these or related questions will help authors develop a working thesis and give their thesis an easy direction and structure.

Step 2 – Start with a Question

While developing a working thesis, early in the writing process, you might already have a research question to address. Strong research questions guide the design of studies and define and identify specific objectives. These objectives will assist the author in framing the thesis statement.

Step 3 – Develop the Answer

After initial research, the author could formulate a tentative answer to the research question. At this stage, the answer could be simple enough to guide the research and the writing process. After writing the initial answer, the author could elaborate further on why this is the chosen answer. After reading more about the research topic, the author could write and refine the answers to address the research question.

Step 4 – Write the First Draft of the Thesis Statement

After ideating the working thesis statement, make sure to write it down. It is disheartening to create a great idea for a thesis and then forget it when you lose concentration. The first draft will help you think clearly and logically. It will provide you with an option to align your thesis statement with the defined research objectives.

Step 5 – Anticipate Counter Arguments Against the Statement

After developing a working thesis, you should think about what might be said against it. This list of arguments will help you refute the thesis later. Remember that every argument has a counterargument, and if yours does not have one, what you state is not an argument — it may be a fact or opinion, but not an argument.

Step 6 – Refine the Statement

Anticipating counterarguments will help you refine your statement further. A strong thesis statement should address —

Why does your research hold this stand?
What will readers learn from the essay?
Are the key points of your argumentative or narrative?
Does the final thesis statement summarize your overall argument or the entire topic you aim to explain in the research paper?

5 Tips to Create a Compelling Thesis Statement

A thesis statement is a crucial part of any academic paper. Clearly stating the main idea of your research helps you focus on the objectives of your paper. Refer to the following tips while drafting your statement:

1. Keep it Concise

The statement should be short and precise. It should contain no more than a couple of sentences.

2. Make it Specific

The statement should be focused on a specific topic or argument. Covering too many topics will only make your paper weaker.

3. Express an Opinion

The statement should have an opinion on an issue or controversy. This will make your paper arguable and interesting to read.

4. Be Assertive

The statement should be stated assertively and not hesitantly or apologetically. Remember, you are making an argument — you need to sound convincing!

5. Support with Evidence

The thesis should be supported with evidence from your paper. Make sure you include specific examples from your research to reinforce your objectives.

Thesis Statement Examples *

Example 1 – alcohol consumption.

High levels of alcohol consumption have harmful effects on your health, such as weight gain, heart disease, and liver complications.

This thesis statement states specific reasons why alcohol consumption is detrimental. It is not required to mention every single detriment in your thesis.

Example 2 – Benefits of the Internet

The internet serves as a means of expediently connecting people across the globe, fostering new friendships and an exchange of ideas that would not have occurred before its inception.

While the internet offers a host of benefits, this thesis statement is about choosing the ability that fosters new friendships and exchange ideas. Also, the research needs to prove how connecting people across the globe could not have happened before the internet’s inception — which is a focused research statement.

*The following thesis statements are not fully researched and are merely examples shown to understand how to write a thesis statement. Also, you should avoid using these statements for your own research paper purposes.

A gripping thesis statement is developed by understanding it from the reader’s point of view. Be aware of not developing topics that only interest you and have less reader attraction. A harsh yet necessary question to ask oneself is — Why should readers read my paper? Is this paper worth reading? Would I read this paper if I weren’t its author?

A thesis statement hypes your research paper. It makes the readers excited about what specific information is coming their way. This helps them learn new facts and possibly embrace new opinions.

Writing a thesis statement (although two sentences) could be a daunting task. Hope this blog helps you write a compelling one! Do consider using the steps to create your thesis statement and tell us about it in the comment section below.

The complexity and requirements of a thesis or dissertation can vary according to the university, program or even country you are studying in. Regardless of the these factors, a good thesis statement is essential to ensure that your thesis can stand its ground and enable you to actively pursue your academic endeavors without any hiccups.

What makes a good thesis statement? Simple answer, precision and enough evidence to support your statement. Writing a statement that appears too broad and is merely based on value judgment isn’t going to win you any points. You also need to determine whether your thesis statement is going to be persuasive/argumentative, expository or analytical. Bear in mind that your thesis statement should be easy enough for you to support your research. If you struggle to write your paper, it would most likely be due to a weak statement. Students can get carried away due to the pressure of writing a compelling thesis statement, only to realize they cannot support the statement they have picked with the required evidence to make the argument stick.

Let’s take a look at a few thesis statement examples, with some tips regarding how to go about writing a research paper based on the examples. The following is meant to provide readers with ideas regarding what type of statements can help them with their thesis and how they can back it up with evidence. You might also want to check out our post about how to write an essay to get ideas regarding how to go about writing a quality thesis to support your statement.

Thesis Statement: The rise of online shopping in the wake of COVID-19 might lead to the permanent closure of millions of brick-and-mortar outlets.

The above statement can be deemed analytical, with a need for evidence to support the statement. There have been several research reports, statistics and forecasts on the rise of online shopping retailers like Amazon amidst the crisis. Similarly, many outlets including Microsoft’s retail outlets have closed permanently during the pandemic. There has also been closure of virtually every type of business from across a wide array of industries due to COVID-19, especially the ones that have failed to digitize. You can also make your statement more specific by focusing on closure of retail outlets, eateries, etc.

Note that the above statement does not discuss the closure of businesses but the physical outlets. For example, Microsoft closed its retail outlets but the products can still be bought online or through various other vendors/stores.

Thesis Statement : Because many people might be unwilling to vaccinate in country x due to their reluctance towards a COVID-19 vaccine, the government must ensure that mass awareness campaigns regarding the need to vaccinate starts prior to the launch of the vaccine.

This statement makes a case for the use of vaccination by convincing people to vaccinate as soon as a new vaccine becomes available. This is a persuasive statement, which can be backed by evidence regarding how anti-vaccination drives and misconceptions have in the past led to the spread of disease. For example, misconceptions and resistance towards the polio vaccine has resulted in cases still being reported in countries like Afghanistan and Pakistan.

Thesis Statement : As physical libraries become obsolete due to digital devices, the government should fund digital libraries instead of physical ones to ease the economic burden of students required to buy expensive e-books.

The above statement would require the individual writing the paper to make a strong case regarding why physical libraries are more expensive and less efficient to manage as compared to virtual libraries that can help students acquire books without incurring heavy charges for renting or purchasing e-books. You can also make a case for open education resources to help students excel in their studies.

Thesis Statement: The government should digitize libraries and provide increased resources to support digital devices, such as new computers, high-speed internet connectivity for remote devices and online access to books.

The example statement above is an alternative version of the statement which suggests increased digitization of libraries. The research paper can include arguments regarding the changing nature of how people now prefer e-books instead of paperback and how students require high-speed internet to connect to a number of remote devices and make the entire library available online. The thesis statement is referring to the government in your country. It is quite possible that your country does not yet offer one or more of the aforementioned services in government-run libraries and they might be becoming irrelevant.

Thesis Statement: The cost of healthcare services for most people in country X is unbearable due to low average incomes, high prices of essential medicines and lack of government-funded hospitals.

This analytical statement singles out a country and mentions that the majority of people are unable to afford healthcare services due to low average incomes, expensive essential medicines and lack of government-funded hospitals. There are a number of developing countries which suffer from this phenomenon. Some low-income countries even have one hospital per five million people and not even a basic health unit in most parts of the country. Furthermore, medicine prices are heavily impacted by exchange rates and a weak currency is likely to drive up prices for poor countries relying on imported medicine. All the required information such as average income, data on government hospitals and medicine prices can be usually acquired for a country through official sources, as well as independent research. This can help provide enough evidence to back your statement.

Thesis Statement: Increased taxation on cigarettes can help save the government on healthcare-related expenditure which can be used for improving healthcare services in the country.

There are three aspects to cover in this statement. One is the application of taxes and to prove that it will help people move towards smoking cessation or alternatives. This will have to be backed by similar results from other countries. For example, countries like the UK and New Zealand have over the years heavily taxed cigarettes and reduced smoking. The evidence related to this can be used for this statement. The second part deals with the government saving on healthcare expenditure which will require explaining the existing burden on healthcare due to e.g. increase in cigarette-induced cancer and other diseases such as tuberculosis, chronic obstructive pulmonary disease, heart diseases, etc. Lastly, a case can be made regarding the need for improving healthcare services and how the money from a reduced healthcare burden can help do that.

Thesis Statement: A diverse group of people working on projects related to human development can help improve the planning and efficiency of development programs designed for marginalized communities.

Development sector organizations, especially international non-government organizations often try to account for diversity, where people from different, ethnic, religious and educational backgrounds are hired for executing human development programs. Many times, some people are also hired from other countries to bring their experience to the table.

Thesis Statement: Blue-collar workers whose jobs are vanishing in province X should be retrained for work in green energy to reduce unemployment, improve the environment and local economies.

In recent years, many blue-collar jobs have vanished in many countries due to slowing global demand, global recession, the rise of Chinese manufacturing firms and more recently, COVID-19. This statement can also be limited to a local economy to further narrow its scope. The statement can be backed by evidence related to vanishing of jobs for blue-collar workers, the need for improving the environment, e.g. due to deteriorating air quality, solid waste management challenges, rise of plastic pollution, etc.

The case for reducing unemployment and improvement in local economies can also be made by pointing towards data related to unemployment rates, closure of industries in province x and how green energy initiatives can help cope with environment and socio-economic problems. You can make a case for either using green energy for local consumption or to export electricity to neighboring countries with increasing electricity demands and low capacity.

Thesis Statement: Wind turbines need to be replaced with alternative sources of green energy due to their hazardous effect on human health and wildlife.

The above statement makes a case against wind turbines. While they were hailed as an alternative source of renewable energy in the past, research has suggested that the noise and effects of wind turbines on humans and wildlife can be quite adverse. This includes not only birds dying due to collisions with the turbines but also the noise pollution caused by them. To back such a thesis statement, you will have to not only state facts and research related to the subject but also state viable alternatives and comparisons, proving why they are better than wind turbines.

Thesis Statement: Governments should prioritize climate change adaptation since global warming cannot be reversed.

This is an example of a fairly ambitious thesis statement. It caters towards not only covering climate change but makes a bold statement that global warming cannot be stopped. This topic is subject to much debate, with claims that the carbon in the atmosphere can no longer be reduced. The topic has enough research and data available to make a case. Furthermore, climate change adaptation is a hot topic and many governments around the world are working on their adaptation strategies. However, such a topic can still be quite controversial and undertaking such a thesis can be ambitious, as the counter-arguments can be as strong as the narrative you might present.

Thesis Statement: The integration of blockchain technology in supply chain management can enhance transparency, traceability, and efficiency, reducing the risk of counterfeit products and ensuring product authenticity.

Thesis Statement: The development of artificial intelligence (AI) chatbots in customer service has the potential to revolutionize customer interactions, providing personalized assistance and improving overall customer satisfaction.

Thesis Statement: Implementing 5G technology can accelerate the Internet of Things (IoT) ecosystem, enabling seamless connectivity and driving innovation in various industries, such as healthcare, transportation, and smart cities.

Thesis Statement: The transition to renewable energy sources, such as solar and wind power, is essential for mitigating the impacts of climate change and reducing carbon emissions globally.

Thesis Statement: Sustainable waste management practices, including recycling and waste-to-energy technologies, can significantly reduce waste and create a circular economy.

Thesis Statement: Biodiversity conservation and protecting endangered species are critical for maintaining ecosystem balance and preserving the planet’s natural resources for future generations.

Thesis Statement: Implementing comprehensive gun control measures is necessary to reduce gun violence and enhance public safety in communities.

Thesis Statement: Addressing income inequality through progressive taxation and social welfare programs is crucial for promoting social equity and reducing poverty rates.

Thesis Statement: Promoting gender equality in the workplace, including equal pay and representation in leadership positions, is essential for achieving inclusive economic growth and sustainable development.

Thesis Statement: Mindfulness-based interventions can effectively reduce stress and anxiety levels in individuals, improving their overall mental well-being and resilience.

Thesis Statement: Early intervention and access to mental health services for children and adolescents can prevent the development of mental health disorders and improve long-term outcomes.

Thesis Statement: The study of cognitive biases and heuristics provides valuable insights into decision-making processes, leading to a better understanding of human behavior in various contexts.

Thesis Statement: Analyzing primary sources and historical documents can lead to a deeper understanding of historical events, shedding light on the perspectives and motivations of different actors.

Thesis Statement: The study of colonialism and its impact on indigenous cultures can provide insights into the historical roots of present-day social and cultural dynamics.

Thesis Statement: Examining the role of women in historical revolutions can reveal their contributions to social and political change, challenging traditional narratives of male-dominated history.

You might need to present a PowerPoint presentation to defend your thesis. In such a case there are a number of things you can do to make sure that you are able to concisely explain your argument while keeping your audience engaged. You can read all about our tips from this post about thesis presentation .

A good thesis statement is the foundation for your thesis. A weak statement is likely to lead to a roadblock in proving your statement. Your thesis statement should be flexible enough for adjustment, as sometimes a student might need to rewrite a thesis statement for a working thesis. In such a case you can save time and effort by leaving room for flexibility so you don’t have to start from scratch.

Frequently Asked Questions

What is a thesis statement examples.

A thesis statement is a concise declaration that encapsulates the main argument or focus of an academic paper or essay. It serves as a roadmap for readers, conveying the purpose and direction of the work. For instance, in an essay about climate change, a thesis statement could be: “The urgent need to mitigate climate change is evident through the alarming rise in global temperatures, the increased frequency of extreme weather events, and the rapid melting of polar ice caps.” This statement clearly outlines the essay’s key points, guiding the reader on what to expect and highlighting the author’s stance.

Are thesis statements used in fictional writing?

Thesis statements, including research papers and persuasive essays, are primarily used in nonfiction writing. In fictional writing, such as narrative essays, authors may use a thesis statement to emphasize the story’s significance or the intended lesson they want readers to take away from the narrative.

Can a thesis statement be two sentences long?

While a thesis statement can be two sentences long, it is often preferred to keep it concise and limit it to one sentence. A single-sentence thesis statement is easier for readers to identify, and placing it at the end of the introductory paragraph allows for a clear and focused presentation of the topic.

Can a thesis statement be too broad or too narrow?

Yes, a thesis statement can be problematic if it is too broad or too narrow. A good thesis statement should strike a balance and have a strong focus. If it is too broad, it becomes challenging to cover all aspects within the scope of the paper. Conversely, if it is too narrow, insufficient research or evidence may support the claims effectively. Aim for a thesis statement that clearly identifies the topic and presents your stance, providing readers with a clear understanding of what to expect in the paper.

Writing a Paper: Thesis Statements

Basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable. We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors. We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators. The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

In this essay, I argue ____, using ______ to assert _____.
While scholars have often argued ______, I argue______, because_______.
Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

What exactly is a thesis statement?

What if I told you that one sentence in your essay or thesis could be the difference between a First and a Fail?

It may sound absurd – perhaps even unfair – but it’s true. I refer, of course, to the thesis statement. A thesis statement is your entire essay if it were condensed into a single sentence. If your essay title is a question, then your thesis statement is the one-sentence answer.

It tends to arrive near the end of the first paragraph of a thesis.

Let’s take a look at an example from a Master of Education degree thesis:

Thesis title What constitutes ‘good writing’ for GCSE students of English?

Thesis statement The examination rubric by which GCSE English writing performance is assessed, influenced by a long history of variable ‘tastes’, may now be said to describe ‘good writing’ as that which is grammatically accurate, sophisticated, and suited to purpose, genre and audience.

(The thesis statement would be located in paragraph 1, after a brief overview of the subject).

Why is a thesis statement important?

As I mentioned, the way your thesis statement is written can be the difference between a First and a Fail. But how?

To answer that, let’s think about what ‘thesis’ means. From the Greek thésis, meaning ‘proposition’, your thesis is your main argument.

It is the position you have to support and defend for the remainder of your essay. Without something clear to defend, the fortress you build will crumble and the army you deploy will run about like headless chickens.

In essence: without a clear thesis statement, you don’t have an essay.

“Establishing a clear thesis at the start of your essay is crucial for both you and your examiner. For your examiner, it’s evidence that you have answered the question. For you, it can function as an essay plan.”

For both of you, it’s a litmus test for the quality of the argument: if you can’t fit your essay’s arguments into a sentence, they are too diffuse; and if you can’t stick to your thesis statement’s focus throughout your essay, you are not focused.

A precisely focused and well-grounded essay is more worthy of a First Class grade than one with a scattergun approach.

What should a thesis statement include?

What your thesis statement includes is determined by three things:

1. The subject and topic of the essay. 2. The purpose of the essay. 3. The length of the essay.

Let’s examine each of those in more detail to see how they can help us refine our thesis statement.

The subject and topic of the essay

Look at this real-life title from an undergraduate Sports Science essay:

What are the key differences between training recommendations for maximising muscular strength and maximising muscular hypertrophy?

The first task is, of course, to determine the subject of the essay.

In this example, that would be ‘training recommendations for maximising muscular strength and training recommendations for maximising muscular hypertrophy’.

Knowing that means that I know I will need to deploy my knowledge about those two similar but distinct areas. It also means that I should be using the specialist terminology relevant to the field, such as load, isotonic and volume.

Next, I need to determine the topic.

Here it would be ‘the key differences’ between training recommendations for those two goals. That phrase ‘key differences’ is likely to be at the heart of my thesis statement, to show that I’m on track.

With that in mind, my thesis statement might look like this:

Whilst both training outcomes require resistance training centred upon isotonic contractions, it is likely that the absolute load requirements may need to be higher for strength purposes, whilst the total training volume may need to be higher for hypertrophy purposes.

It is by no means a complete essay, but it states clearly what the ‘short answer’ to the question is, whilst paving the way for the ‘long answer’ to follow.

But what if the essay isn’t just looking for the facts organised into a specific order? What if the essay is asking for analysis? Or an argument?

The purpose of the essay

Different essay purposes require different thesis statements. Fortunately, there are only three main essay purposes, and they’re pretty easy to recognise:

1. The expository essay: This is an essay type that asks for the key facts on a subject to be laid out, with explanations. The Sports Science question above is an example of this. It asks for the WHAT and HOW of something.

2. The analytical essay: This essay type asks you not only to lay out the facts, but also to analyse and deconstruct them to better understand them. It is typical in subjects such as English Literature and Fine Art. It asks for the WHY of something.

3. The argumentative essay: This type of essay asks you to use the facts available, to analyse them for value, and then to provide a point of view about the subject. It moves more quickly through the WHAT, HOW and WHY of a topic through to: WHY DOES IT MATTER?

All of the above essay types need a thesis statement that includes a proposition (a statement which answers the question or addresses the title).

Beyond that, these three essay types all require different additions.

For the expository essay , you need to add an overview of the details of the conclusion. Let’s look at an example:

Expository essay title: What are the key differences between training recommendations for maximising muscular strength and maximising muscular hypertrophy? (BSc in Sports Science)

Expository thesis statement: Whilst both training outcomes require resistance training centred upon isotonic contractions, it is likely that the absolute load requirements may need to be higher for strength purposes, whilst the total training volume may need to be higher for hypertrophy purposes. (The basic conclusion is that both approaches need isotonic resistance training; the details are teased out in bold.)

For the analytical essay , you need to add an overview of the analysis performed. Here’s an example:

Analytical essay title: Why did England and Wales vote to leave the European Union? (BA in Politics)

Analytical thesis statement: A close consideration of the voter demographics, the populist nature of political messages leading up to the referendum, and the history of Britain’s status in the EU, will demonstrate that Brexit was primarily motivated by the machinations of the Right.

(The basic conclusion is that Brexit was influenced by politicians; the analytical approach is in bold.)

For the argumentative essay , you need to add an overview of your reasoning. Another example:

Argumentative essay title: To what extent do you consider the authorship of Shakespeare’s plays to be in question? (BA in English Literature)

Argumentative thesis statement: Shakespeare’s authorship of his plays is beyond question, given both the entirely unconvincing nature of any counter-theories and the relatively unstable conception of the playwright’s identity as it stands. (The basic conclusion is that Shakespeare did write his plays; the reasoning is in bold.)

As you can see from these examples, the purpose of the essay gives a very clear demand for something beyond a simple answer.

But, there’s more!

The length of the essay

The prescribed length of the essay also defines what you need to do with your thesis statement.

Your thesis statement is a microcosm : a miniature, compressed version of your whole essay.

So, it makes sense that the length of the actual essay is going to impact upon the content of the thesis statement.

If, for example, your essay is expected to be 800 words long and on the subject of Eve in the Bible, then it would be overly ambitious for your thesis statement to say: ‘through comprehensive study of the Bible and extant criticism’. For an 800 essay, more precision will be necessary. It would be better for your thesis statement to say: ‘with due awareness of the complexity of the issue, focusing on feminist readings of Genesis .’

“Matching the scope given in your thesis statement to the depth you provide in your essay is a very effective way to ensure precision.”

Contrastingly, if your essay is expected to be 80,000 words long (a PhD thesis, for example), on the subject of stop-motion animation, it would be rather unambitious to suggest that the essay will ‘provide a visual analysis of Wallace and Gromit: The Wrong Trousers’, only. For a PhD, we would expect more content to be covered, and multiple approaches to analysis to be considered.

Indeed, matching the scope given in your thesis statement to the depth you provide in your essay is a very effective way to ensure precision.

So, to summarise, how do I write a thesis statement?

It’s a simple, three-part process:

1. Identify the question in the title (or make a question from the statement). 2. Answer that question in as few words as possible. 3. Complete the sentence by providing an overview of the foundation behind your answer.

Easy, right? It can be!

That said, there are plenty of traps that essayists can fall into with this part of the essay. Let’s look at some of these pitfalls and how to avoid them.

Pitalls to Avoid

Pitfall #1: amateurish style.

This is common throughout academic essays written by beginners. It’s not just the thesis statement that falls foul of sounding amateurish. There are plenty of ways this happens, which are beyond the scope of this argument, but the following example is a prime example: In this essay, I will explore the various pieces of evidence before concluding.

This is amateurish for a few reasons. Firstly, it doesn’t actually say anything. You could otherwise word it, ‘I will write an essay which answers the question’ – a rather wasted sentence. The next, and more forgivable issue is the use of the first-person. We want to get a sense that an individual wrote this essay, but we never want to hear them mentioned! Make sense? No? Sorry.

This should instead read more like:

This essay considers evidence from X in light of Y which ultimately reveals Z at the heart of the issue.

(It focuses on the specifics, X, Y, and Z, and is devoid of any mention of its author.)

Pitfall #2: empty phrasing

This is similar to amateurish style. However, empty phrasing is not just amateur-sounding; it’s manipulative-sounding.

Using phrases such as “in order to” instead of, simply, “to” – or “due to the fact that” instead of just “as” – look like attempts to fill up the word count with waffle rather than content. The same goes for phrases that can be substituted for one word: ‘it is evident that’ can (and should) become ‘evidently’.

Watch this thesis statement from a GCSE essay on Music go from hideous to tolerable:

Beethoven was unable to hear his work, due to the fact that he was deaf, so it is evident that he musically conceptualised the notes in order to compose. (Wordy!)

Beethoven was unable to hear his work, as he was deaf, so it is evident that he musically conceptualised the notes to compose. (Slightly less wordy.)

Beethoven’s deafness made him unable to hear his work, so evidently he musically conceptualised the notes to compose. (About as concise as such a complex sentence will get…)

Do not mistake wordiness for sophistication. Your ideas should be sophisticated; your writing should be clear.

Pitfall #3: non-standard grammar

For an examiner, the English language is not just a vehicle for your ideas. It should be, but the academic process always involves the assessment of your expression.

So, to satisfy our examiners’ prescriptive tastes, we need to adhere to the basic tenets of Standard English.

Take a look at the following thesis statement example from an A Level Sociology essay: Considering the status of BAME in Internet culture, the demonstrably racist treatment at the hands of the police, and the energy behind the BLM protests, concluding that there is hope for the future.

This sentence has no finite main verb, so it is technically not a sentence. To become a grammatical sentence, we would need to make ‘concluding’ finite: ‘it can be concluded’, or ‘we conclude’.

The writer got lost in this example because the sentence was so long!

Long sentences can also lead to a failure to make subject and verb agree, like in the next thesis statement example from a school Geography essay:

The most populous municipalities of Spain, Madrid, Barcelona, Valencia, Seville, and Zaragoza, does not rank in the top ten most dense populations of the country, with the exception of Barcelona.

Because the subject ‘municipalities’ is separated from the verb ‘does’ by eight words, it is easy to forget that they do not agree. It should, of course, be ‘do, not ‘does’.

Final words

The thesis statement, as I said at the start, can be the difference between a First and a Fail. So, take your time with it.

Write it carefully.

Then redraft and refine it several times, until it’s as good as you can make it.

The payoff is a slick, coherent thesis statement that paves the way to a great essay that really impresses your examiner.

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.
