The Ultimate Guide to Writing a Thesis Statement

Matt Ellis

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

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

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

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

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

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

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

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

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

How to write a thesis statement for expository and argumentative essays

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

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

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

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

Thesis statement examples

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

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

How to write a thesis statement for persuasive essays

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

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

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

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

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

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

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

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

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

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

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

1 Brainstorm the best topic for your essay

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

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

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

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

2 Phrase your topic as a question and then answer it

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

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

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

3 Add some polish

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

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

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

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

A thesis statement is a concise description of the goal of your work. This element is one of the most essential components of academic writing , as it tells your readers what they can expect in your paper.

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

If you find yourself in the process of writing a a paper, but you don't know how to create a thesis statement , you've come to the right place. In the next paragraphs, you will learn about the most important elements of a thesis statement and how to come up with one.

A thesis statement highlights the main topic, shows how it will evolve, and conveys clearly the aim of your work. It does not only share the topic but it conveys the conclusion you came up with.

A good thesis statement provides directions for the development of the topic throughout the paper. In sum, this element of academic writing is crucial to sound research .

You can create a great thesis statement by following the format we outlined in our guide How to write a thesis statement .

In general, you should adhere to the following tips to write the best thesis statement:

  • Focus the main idea of your thesis into one or two sentences.
  • Write the answer to the main question of your topic.
  • Clearly state your position in relation to the topic.
  • Do not state the obvious. Give a disputable stance that requires evidence.

Tip: To check if your thesis is clear, explain it to a peer or colleague. If they are confused, then you likely need to re-write it.

Here's an example of a thesis statement:

In what follows, I will explore Fiorina’s position in more depth, focusing especially on her claim that technology is "a great tool for democratization." Ultimately, I argue that the primary problem with Fiorina’s stance lies in her laissez-faire understanding of technology. By granting technology a kind of independent existence apart from human motivation and intent—by positing that "technology permits anybody to play," as if it possesses an autonomy all its own—Fiorina unwittingly opens the way for the very kind of discriminatory and undemocratic mechanisms that her position seemingly rejects.

Tip: Once you finish your paper, return to your thesis statement to make sure that it reflects what you actually wrote.

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

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

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

Yes. Every good essay should include a thesis statement as part of its introduction. Of course, if you are a high school student you are not expected to have an extremely elaborate statement. A couple of clear sentences indicating the aim of your essay will be more than enough.

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’s Covered:

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

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

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

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

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

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

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

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

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

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

Step 2: Figure out what point you want to make

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

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

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

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

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

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

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

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

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

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

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

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

If you’re having trouble getting started, or need some guidance on your essay, there are tools available that can help you. CollegeVine offers a free peer essay review tool where one of your peers can read through your essay and provide you with valuable feedback. Getting essay feedback from a peer can help you wow your instructor or college admissions officer with an impactful essay that effectively illustrates your point.

How do i write a thesis statement.

This page is Part 1 of a two-part handout that continues with our Thesis Statement Checklist .

What is a Thesis Statement?

In an effort to make our handouts more accessible, we have begun converting our PDF handouts to web pages. Download this page as a PDF: See p. 1 of How Do I Write a Thesis Statement Return to Writing Studio Handouts

A thesis statement is a very specific argument that guides your paper. Generally, a thesis statement consists of two parts :

  • A clearly identifiable topic or subject matter
  • A succinct summary of what you have to say about that topic

For your reader, a thesis functions like the case a lawyer has to make to the judge and jury in a courtroom. An effective thesis statement explains to your reader the case you are going to make and how you are going to make it.

For you as the author, your thesis can also help you to stay focused as a writer and determine what information you do (and don’t) need to include in your analysis.

Traditionally, the thesis statement is found near the end of your introduction , though this may change depending on the assignment and context. Don’t be afraid to draft a thesis statement that is more than one sentence.

A Note on Writing Process

You do not need a perfect thesis statement before you draft the rest of the paper. In fact, you will likely need to modify your thesis once you have a complete draft to make sure that your draft and your thesis match one another. If your argument evolves in productive ways as you write, your thesis should, too.

Honing and tweaking a thesis statement during the revision process is ultimately more important than having it exact and precise during the drafting process.

Characteristics of a WEAK thesis statement

  • Vague: Raises an interesting topic or question but doesn’t specify an argument
  • Offers plot summary, statement of fact, or obvious truths instead of an argument
  • Offers opinion or conjecture rather than an argument (cannot be proven with textual evidence)
  • Is too broad or too complex for the length of the paper
  • Uses meaningful-sounding words, but doesn’t actually say anything of substance

Disclaimer: This is not a complete list! You can probably think of many more characteristics of a weak thesis statement.

Characteristics of a STRONG thesis statement

  • Answers a specific question
  • Takes a distinct position on the topic
  • Is debatable (a reasonable person could argue an alternative position)
  • Appropriately focused for the page length of the assignment
  • Allows your reader to anticipate the organization of your argument

Having trouble drafting a thesis? Try filling in the blanks in these template statements:

  • In this paper, I argue that _____, because/by _____.
  • While critics argue _____, I argue _____, because _____.
  • By looking at _____, I argue that _____, which is important because _____.
  • The text, _____, defines _____ as _____, in order to argue _____.

Disclaimer: These are only models. They’ll be useful to help you to get started, but you’ll have to do quite a bit of tweaking before your thesis is ready for your paper.

Tips for Writing Your Thesis Statement

1. Determine what kind of paper you are writing:

  • An analytical paper breaks down an issue or an idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.
  • An expository (explanatory) paper explains something to the audience.
  • An argumentative paper makes a claim about a topic and justifies this claim with specific evidence. The claim could be an opinion, a policy proposal, an evaluation, a cause-and-effect statement, or an interpretation. The goal of the argumentative paper is to convince the audience that the claim is true based on the evidence provided.

If you are writing a text that does not fall under these three categories (e.g., a narrative), a thesis statement somewhere in the first paragraph could still be helpful to your reader.

2. Your thesis statement should be specific—it should cover only what you will discuss in your paper and should be supported with specific evidence.

3. The thesis statement usually appears at the end of the first paragraph of a paper.

4. Your topic may change as you write, so you may need to revise your thesis statement to reflect exactly what you have discussed in the paper.

Thesis Statement Examples

Example of an analytical thesis statement:

The paper that follows should:

  • Explain the analysis of the college admission process
  • Explain the challenge facing admissions counselors

Example of an expository (explanatory) thesis statement:

  • Explain how students spend their time studying, attending class, and socializing with peers

Example of an argumentative thesis statement:

  • Present an argument and give evidence to support the claim that students should pursue community projects before entering college
  • Literary Terms
  • Definition & Examples
  • When & How to Write a Thesis

I. What is a Thesis?

The thesis (pronounced thee -seez), also known as a thesis statement, is the sentence that introduces the main argument or point of view of a composition (formal essay, nonfiction piece, or narrative). It is the main claim that the author is making about that topic and serves to summarize and introduce that writing that will be discussed throughout the entire piece. For this reason, the thesis is typically found within the first introduction paragraph.

II. Examples of Theses

Here are a few examples of theses which may be found in the introductions of a variety of essays :

In “The Mending Wall,” Robert Frost uses imagery, metaphor, and dialogue to argue against the use of fences between neighbors.

In this example, the thesis introduces the main subject (Frost’s poem “The Mending Wall”), aspects of the subject which will be examined (imagery, metaphor, and dialogue) and the writer’s argument (fences should not be used).

While Facebook connects some, overall, the social networking site is negative in that it isolates users, causes jealousy, and becomes an addiction.

This thesis introduces an argumentative essay which argues against the use of Facebook due to three of its negative effects.

During the college application process, I discovered my willingness to work hard to achieve my dreams and just what those dreams were.

In this more personal example, the thesis statement introduces a narrative essay which will focus on personal development in realizing one’s goals and how to achieve them.

III. The Importance of Using a Thesis

Theses are absolutely necessary components in essays because they introduce what an essay will be about. Without a thesis, the essay lacks clear organization and direction. Theses allow writers to organize their ideas by clearly stating them, and they allow readers to be aware from the beginning of a composition’s subject, argument, and course. Thesis statements must precisely express an argument within the introductory paragraph of the piece in order to guide the reader from the very beginning.

IV. Examples of Theses in Literature

For examples of theses in literature, consider these thesis statements from essays about topics in literature:

In William Shakespeare’s “ Sonnet 46,” both physicality and emotion together form powerful romantic love.

This thesis statement clearly states the work and its author as well as the main argument: physicality and emotion create romantic love.

In The Scarlet Letter, Nathaniel Hawthorne symbolically shows Hester Prynne’s developing identity through the use of the letter A: she moves from adulteress to able community member to angel.

In this example, the work and author are introduced as well as the main argument and supporting points: Prynne’s identity is shown through the letter A in three ways: adulteress, able community member, and angel.

John Keats’ poem “To Autumn” utilizes rhythm, rhyme, and imagery to examine autumn’s simultaneous birth and decay.

This thesis statement introduces the poem and its author along with an argument about the nature of autumn. This argument will be supported by an examination of rhythm, rhyme, and imagery.

V. Examples of Theses in Pop Culture

Sometimes, pop culture attempts to make arguments similar to those of research papers and essays. Here are a few examples of theses in pop culture:

FOOD INC TEASER TRAILER - "More than a terrific movie -- it's an important movie." - Ent Weekly

America’s food industry is making a killing and it’s making us sick, but you have the power to turn the tables.

The documentary Food Inc. examines this thesis with evidence throughout the film including video evidence, interviews with experts, and scientific research.

Blackfish Official Trailer #1 (2013) - Documentary Movie HD

Orca whales should not be kept in captivity, as it is psychologically traumatizing and has caused them to kill their own trainers.

Blackfish uses footage, interviews, and history to argue for the thesis that orca whales should not be held in captivity.

VI. Related Terms

Just as a thesis is introduced in the beginning of a composition, the hypothesis is considered a starting point as well. Whereas a thesis introduces the main point of an essay, the hypothesis introduces a proposed explanation which is being investigated through scientific or mathematical research. Thesis statements present arguments based on evidence which is presented throughout the paper, whereas hypotheses are being tested by scientists and mathematicians who may disprove or prove them through experimentation. Here is an example of a hypothesis versus a thesis:

Hypothesis:

Students skip school more often as summer vacation approaches.

This hypothesis could be tested by examining attendance records and interviewing students. It may or may not be true.

Students skip school due to sickness, boredom with classes, and the urge to rebel.

This thesis presents an argument which will be examined and supported in the paper with detailed evidence and research.

Introduction

A paper’s introduction is its first paragraph which is used to introduce the paper’s main aim and points used to support that aim throughout the paper. The thesis statement is the most important part of the introduction which states all of this information in one concise statement. Typically, introduction paragraphs require a thesis statement which ties together the entire introduction and introduces the rest of the paper.

VII. Conclusion

Theses are necessary components of well-organized and convincing essays, nonfiction pieces, narratives , and documentaries. They allow writers to organize and support arguments to be developed throughout a composition, and they allow readers to understand from the beginning what the aim of the composition is.

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

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

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

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

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

Arguable thesis with analytical claim 

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

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

Arguable thesis with normative claim 

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

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

Questions to ask about your thesis 

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

Identifying the Thesis Statement

Learning objectives.

  • identify explicit thesis statements in texts
  • identify implicit thesis statements in texts

You’ll remember that the first step of the reading process, previewing ,  allows you to get a big-picture view of the document you’re reading. This way, you can begin to understand the structure of the overall text. The most important step in getting a good understanding of an essay or book is to find the thesis statement.

A thesis consists of a specific topic and a position statement on the topic. All of the other ideas in the text support and develop the thesis. The thesis statement is often found in the introduction, sometimes after an initial “hook” or interesting story; sometimes, however, the thesis is not explicitly stated until the end of an essay, and sometimes it is not stated at all. In those instances, there is an implied thesis statement, in which you can generally extract the thesis statement by looking for a few key sentences and ideas.

According to author Pavel Zemliansky,

Arguments then, can be explicit and implicit, or implied. Explicit arguments contain noticeable and definable thesis statements and lots of specific proofs. Implicit arguments, on the other hand, work by weaving together facts and narratives, logic and emotion, personal experiences and statistics. Unlike explicit arguments, implicit ones do not have a one-sentence thesis statement. Instead, authors of implicit arguments use evidence of many different kinds in effective and creative ways to build and convey their point of view to their audience. Research is essential for creative effective arguments of both kinds.

Even if what you’re reading is an informative text, rather than an argumentative one, it might still rely on an implicit thesis statement. It might ask you to piece together the overall purpose of the text based on a series of content along the way.

Most readers expect to see the point of your argument (the thesis statement) within the first few paragraphs. This does not mean that you have to place it there every time. Some writers place it at the very end, slowly building up to it throughout their work, to explain a point after the fact. Others don’t bother with one at all, but feel that their thesis is “implied” anyway. Beginning writers, however, should avoid the implied thesis unless certain of the audience. Almost every professor will expect to see a clearly discernible thesis sentence in the introduction.

Thesis statements vary based on the rhetorical strategy of the essay, but thesis statements typically share the following characteristics:

  • Presents the main idea
  • Most often is one sentence
  • Tells the reader what to expect
  • Is a summary of the essay topic
  • Usually worded to have an argumentative edge
  • Written in the third person

In academic writing, the thesis is often explicit : it is included as a sentence as part of the text. It might be near the beginning of the work, but not always–some types of academic writing leave the thesis until the conclusion.

Journalism and reporting also rely on explicit thesis statements that appear very early in the piece–the first paragraph or even the first sentence.

Works of literature, on the other hand, usually do not contain a specific sentence that sums up the core concept of the writing. However, readers should finish the piece with a good understanding of what the work was trying to convey. This is what’s called an implicit thesis statement: the primary point of the reading is conveyed indirectly, in multiple locations throughout the work. (In literature, this is also referred to as the theme of the work.)

Academic writing sometimes relies on implicit thesis statements, as well.

This video offers excellent guidance in identifying the thesis statement of a work, no matter if it’s explicit or implicit. As the video below argues, every piece of writing has a thesis statement.

How To Write a Good Thesis Statement in Five Steps

Writing a thesis statement can be intimidating, sure, but it doesn’t have to be hard. Below, we’ll go over five steps that can help you write an effective thesis statement.

A thesis statement should encapsulate the main idea of your text in one sentence.

Quick Summary on Writing a Thesis Statement

  • A thesis statement encapsulates the main idea or point of your entire text in one effective, assertive, and clear-cut sentence.
  • The five steps to writing your thesis statement are:

What Is a Thesis Statement?

A thesis statement is a sentence found at the end of the introduction paragraph (usually the last sentence) that briefly yet thoroughly explains the main idea or point of the rest of your text. Writing a good thesis statement is essential because it helps your readers understand your objective from the start—there’s no guessing game. An effective thesis statement also has the power to draw readers in by showing why your topic is worth reading (and writing) about.

How To Write an Effective Thesis Statement

1. choose a topic..

Before writing a good thesis statement, you’ll have to decide what you’re writing about. This step requires a lot of thought because you want to pick a topic that you’re passionate about, but that can also resonate with a wide audience.

2. Set your objective.

Next, ask yourself what your goal is. This is in line with deciding what type of text you’ll be writing—expository, persuasive, narrative, etc. It’s always crucial to believe in what you’re writing. This might be tricky, especially if the topic was chosen for you, but you can always try to find an angle that you can wholeheartedly support.

3. Encapsulate the main point of your text in as few words as possible.

Now it’s time to write the thesis statement . Remember, a thesis statement sums up the point of your entire text. It works as a sort of guide for your readers, so they know what to expect. Ask yourself, “How can I capture the main essence of my writing into one sentence?” And keep this in mind while you’re writing it: An effective thesis statement explains what you’re writing about and asserts your perspective on it.

4. Check for spelling and grammar errors.

You’ve probably heard that you’re not supposed to edit as you write, which is true in many cases. But because the thesis statement sets the tone for the rest of your writing, you may not want one riddled with spelling and grammar errors. Check for mistakes in your thesis statement before continuing writing. If you want additional help, you can always use LanguageTool as your writing assistant, so all you have to focus on is writing. This multilingual text editor can do the checking for you to ensure flawless text.

5. Revise your thesis if need be.

The writing process can be enlightening. Sometimes your perspective on something may shift as you gain a new understanding while writing about it. It’s no problem if this happens, just make sure your thesis statement matches the rest of your writing.

Writing a Thesis Statement

Here’s an example of a well-written thesis statement:

Having a pet not only helps you feel a sense of companionship, but they also offer a plethora of physical and mental health benefits, which I’ll be discussing in detail.
  • Remember: When brainstorming your thesis statement, ask yourself, “What are you writing about, and what’s your take on it?”
  • That’s the question your thesis statement should answer throughout your writing, and should be reiterated in the conclusion .
  • Thesis statements are important, so make sure you set enough time aside to write a powerful one.

Mastering the Thesis Statement: Examples and Tips for Academic Success

What is the thesis statement? When it comes to writing an essay , there are many things that we must take into consideration in order to create a well-written and respected piece of work. One such thing is the thesis statement. Every good essay should have one and it needs to be well-written and well-thought-out. In this article, we are going to be looking at exactly what a thesis statement is and what it is used for as well as looking at some examples of the thesis statement as a way to gain a greater understanding of what its function is.

A thesis statement plays a crucial role in any well-crafted essay, as it helps both the writer and the reader establish the central point of the paper. Typically found near the end of the introduction, this sentence succinctly conveys the main idea the writer intends to communicate throughout the essay. Crafting a strong thesis statement increases the likelihood that the resulting essay will be cohesive, persuasive, and engaging for the audience.

Creating an effective thesis statement can, at times, be a challenging process. One useful method is to begin by exploring examples that illustrate the various ways in which thesis statements can be constructed, depending on the type of essay or paper being written. Studying these examples can help budding writers grasp the principles behind crafting compelling thesis statements, and serve as inspiration for their own work.

What Is A Thesis Statement?

Definition and purpose.

In the most simple terms, a thesis statement is a short statement that provides insight into what the essay is going to be about. They are used to enlighten the audience on a variety of things, including:

  • The main argument or point to be discussed.
  • The purpose of the essay.
  • The point of view of the author on a specific topic.

A thesis statement is a sentence that encapsulates the central point or main idea of a paper or essay. It is typically found near the end of the introduction and serves as a guide to the reader, outlining the writer’s stance on the topic. The thesis statement not only answers the question asked but also acts as a roadmap for the paper, indicating what the reader can expect throughout the rest of the paper.

The purpose of a thesis statement is two-fold:

  • To convey a clear and concise argument or position on the topic.
  • To inspire further discussion and responses from the audience.

It’s crucial for a thesis statement to be focused, specific, and arguable. A strong thesis is easy to understand and provides a solid foundation for supporting evidence within the paper.

Types of Thesis Statements

Argumentative thesis statement.

An argumentative thesis statement is a claim that takes a strong position on an issue. This type of thesis statement aims to persuade the reader to accept the writer’s viewpoint by presenting logical reasoning and supporting evidence. It is essential to have a clear and concise argumentative thesis statement to guide the rest of the essay.

For example: “ Public transportation should be free in metropolitan areas to reduce carbon emissions and economic inequalities.”

Expository Essay Thesis Statement

An expository essay thesis statement highlights a specific issue or fact that the writer will explain or analyze throughout the essay. This type of thesis should be informative and objective, without taking a strong stance on the issue.

For example: “ High-level competitive athletes face numerous physical, mental, and emotional challenges throughout their careers. ”

Persuasive Thesis Statement

A persuasive thesis statement is similar to an argumentative thesis statement, but it aims to convince the reader to take action or adopt the writer’s viewpoint through emotional appeal and relatable examples. The persuasive thesis statement should be thought-provoking and debatable.

For example: “ Animal shelters should require background checks and home visits to ensure responsible pet adoption and prevent animal abuse. ”

Compare and Contrast Thesis Statement

A compare-and-contrast thesis statement sets the stage for an essay comparing or contrasting two or more subjects. This type of thesis statement may highlight similarities, differences, or a mix of both. It is crucial to establish a basis for comparison to provide a clear focus for the essay.

For example: “ While both public and private universities offer a variety of educational opportunities, the differences in cost, class size, and campus environment directly impact a student’s experience .”

By understanding and applying these types of thesis statements, writers can effectively tailor their essays’ tone and focus to suit their specific purpose and audience.

How Is A Thesis Statement Used?

As we mentioned a thesis statement is used to point out the main argument of the essay. There are certain rules that should be followed by the thesis statement. Let’s take a look at these in a little more detail.

  • A thesis statement should appear in the introduction of the essay to layout the main topic and the author’s stance on it. It should also appear in the conclusion of the essay, where the author can refer back to it.
  • A thesis statement should be a short statement of only one or two sentences that delivers clear and concise information.
  • The thesis statement will directly answer the main question posed by the essay, for example, if the essay question were ‘What is the biggest tourist attraction in France?’ The thesis statement might directly reply to this with ‘With over 6 million visitors each year, the Eiffel Tower is clearly the biggest tourist attraction in France.’ If the essay topic doesn’t contain a question, you can fashion one yourself.
  • Many people use the ‘so what?’ technique when writing a thesis statement. If a reader is likely to think ‘so what?’ when starting your essay, you can use the thesis statement to form a relationship and a connection to the issue that will engage the reader and make them care about what is going to be talked about.
  • Similarly to the above point, a thesis statement should answer why or how questions that the reader may have. Look again at the example of the Eiffel Tower, the statement clearly shows the reader why the tower is the biggest tourist attraction in France using real statistics that cannot be ignored. But in the same breath, gives the reader the chance to dispute the information. This is another key point to the thesis statement. A reader should be able to look at the thesis statement and disagree with it, this might encourage them to research the topic themselves.
  • A thesis statement should agree with the body of the essay. If it does not, then it should be amended. Using the example of the French tourist attraction once again, the body of that essay would need to go into further detail about the tourist attractions in France and further prove why the Eiffel Tower is the most popular.

Creating a Strong Thesis Statement

Identifying your topic and scope.

When creating a strong thesis statement, it is essential to first identify your topic and the scope of your paper. You should consider the central idea you want to communicate and its impact on your field of study, whether it’s art, education, or environmental studies. A solid thesis statement should focus on a single aspect of your research, avoiding general terms or abstractions. Keep it clear and specific to ensure it effectively guides both you and the reader through your argument.

Forming a Debatable Claim

An argumentative thesis statement should present a debatable claim, one that reasonable people could disagree with. This means that it should not merely be a statement of fact, but rather an assertion that invites different opinions. For example, a debatable claim on nationalism could be, “Nationalism contributed to the rise of populism in the 21st century.” This claim allows for various arguments, opinions, and contextual interpretations.

Providing Evidence

A strong thesis statement should also set the stage for presenting evidence supporting your claim. In a research paper, this means providing an overview of the key elements and sources you will use to build your argument. For an argumentative essay, be prepared to provide well-researched and detailed evidence to back up your claim, whether it’s regarding renewable energy sources, the history of race and gender, or the role of nationalism in shaping global politics.

Here are some tips to help you write a strong thesis statement:

  • Make sure it’s clear and concise, typically consisting of one or two sentences.
  • Ensure that it’s focused and specific enough to be “proven” within the boundaries of your paper.
  • Position it near the end of your essay’s introduction or within the first paragraph.

By following these guidelines and being mindful of your topic, scope, and evidence, you will be able to craft a powerful thesis statement that engages your audience and sets the stage for a successful research or argumentative paper.

Thesis Statement Examples

Argumentative thesis examples.

An argumentative thesis aims to establish a position and persuade the reader with evidence and reasoning. Examples include:

  • Though populism may fundamentally challenge traditional political structures, its effects on social and economic policies are necessary for a more equitable society.
  • Social media platforms are responsible for the increasing polarization of opinions and must adopt measures to limit the spread of misinformation.

Expository Essay Thesis Examples

An expository essay thesis presents facts, evidence, or an explanation without taking a persuasive stance. Examples include:

  • The process of photosynthesis is fundamental to the survival of plants and the ecosystems they support, providing energy for growth and reproduction.
  • Urbanization has led to numerous social, economic, and environmental consequences, including increased housing demand, traffic congestion, and pollution.

Persuasive Thesis Examples

A persuasive thesis seeks to convince the reader of a particular argument or opinion. Examples include:

  • The benefits of implementing a universal basic income outweigh the potential drawbacks, as it can alleviate poverty and provide residents with more financial security.
  • Investing in renewable energy sources is essential for combating climate change and ensuring a sustainable future for subsequent generations.

Compare and Contrast Thesis Examples

A compare and contrast thesis highlights the similarities and differences between two or more subjects. Examples include:

  • While both traditional and online education offer unique advantages and challenges, the flexibility and accessibility of online learning make it a more suitable option for students juggling work and personal responsibilities.
  • Despite similarities in their genre and themes, the novels “Pride and Prejudice” and “Wuthering Heights” differ significantly in their narrative styles and characterization.

Using these examples, you can create strong thesis statements tailored to your essay’s specific topic and goals. Remember to provide a clear and concise thesis that effectively showcases your argument, opinion, or comparison in a confident, knowledgeable, and neutral tone.

Thesis Statement Examples: Issues to Consider

Impact on society.

When creating a thesis statement, it’s essential to consider the potential impacts on society. The chosen topic may address issues such as education, war, and nationalism. For example, the thesis statement might analyze the effects of changing educational policies on different classes of society. This could include exploring access to education for low-income households or the impact of privatization on public schools. It is crucial to examine how the thesis topic relates to societal issues and incorporates them into the statement.

Related: Social Issues

Race, Gender, and Class

It is important to address issues related to race, gender, and class when developing thesis statements. For instance, research papers might examine inequalities in the workplace or disparities in access to resources. Such studies should think about context and historical background, comparing and contrasting the experiences of different groups. Here are some examples.

  • Gender : An examination of the gender pay gap across various industries
  • Race : A comparison of racial profiling incidents in law enforcement across different communities
  • Class : Exploring the impact of socio-economic status on healthcare access and outcomes

Consider using tables and bullet points to help present data and findings more effectively.

Environmental Concerns

Lastly, incorporating environmental concerns into thesis statements is essential, especially in today’s world, where sustainability and environmental protection are vital. Research papers might address issues such as pollution, waste management, or the effects of climate change on marginalized communities. For example, a thesis statement could focus on exploring the consequences of a specific eco-friendly initiative in a local community, or how environmental policies have evolved over time.

Keep in mind to maintain a confident, knowledgeable, neutral, and clear tone of voice throughout the section, focusing on accurate information and avoiding exaggerated or false claims.

Examples of Thesis Statements in Different Essay Types

In a narrative essay , the thesis statement revolves around the story being told. It is typically centered on a specific event, person, or experience that had a significant impact on the writer. The thesis statement in a narrative essay serves as a brief preview of what the reader can expect. It should provide some insight into the writer’s personal connection to the topic and help set the stage for the narrative to unfold.

For example:

The moment she won the lottery, Mary’s life changed forever, teaching her the importance of cherishing every moment with her loved ones.

An analytical essay breaks down a topic into its main components and presents an evaluation or interpretation of the topic based on those components. The thesis statement in an analytical essay should clearly state the issue or idea that will be analyzed and its essential elements. This type of statement should provide enough information to guide the reader through the essay and highlight the central points of analysis.

By examining the symbolism, characterization, and theme of “The Great Gatsby,” it becomes evident that Fitzgerald uses these techniques to criticize the American Dream’s materialism and superficiality.

Argumentative

In an argumentative essay , the thesis statement takes a clear, definitive stance on a specific issue or question. This type of thesis statement aims to persuade readers of the writer’s viewpoint and provide logical and supporting evidence to back up the claim. The thesis should be concise, specific, and controversial enough to encourage debate from various perspectives.

Although some people argue that video games can be beneficial, this essay will demonstrate that excessive video gaming is linked to increased violent behavior, addiction, and social isolation, and therefore requires stricter regulation.

Cause and Effect

A cause-and-effect essay explores the relationship between certain events, actions, or conditions and their respective outcomes. The thesis statement in a cause-and-effect essay should establish the connection between the cause and the effect, asserting a causal connection between the two. This type of thesis statement should present a clear, coherent structure to guide the reader through the essay and should establish the relationship between the cause and the effect.

The widespread use of smartphones has led to increased incidents of sleep deprivation among teenagers, resulting in declining academic performance, mood disorders, and health issues.

These are examples of how thesis statements can vary based on the type of essay and showcase the importance of tailoring the thesis statement to fit the specific requirements of each essay style.

More Thesis Statement Examples

Now that we are clear on what a thesis statement is and how it can be used, we are going to take a look at some examples of strong and effective thesis statements. This will give you a better idea on what they should contain and how they function within an essay.

American Education

The American education system has been evolving, and it is essential to have a clear thesis statement when discussing the topic. Here’s an example:

The integration of technology in American schools has significantly enhanced the learning experience of students, resulting in improved academic performance.

In this example, it highlights the positive impact of technology on the education system. It also provides a concise view that can be explored and supported through research and relevant statistics.

Internet and Society

The internet has changed the way society functions in various capacities. Here is a thesis statement example that can be used to discuss the relationship between the internet and society:

The widespread use of the internet has drastically altered societal interactions, affecting the population’s ability to communicate, access information, and maintain personal privacy.

This statement outlines the primary effects of the internet on society and can be further developed through specific examples and analysis. This statement can be supported through studies, data, and real-life cases that demonstrate the impact of the internet on communication, information access, and privacy concerns.

List of Thesis Statement Examples

  • Owing to the fact that many children are not being vaccinated because of illness, it is now imperative that we make it a requirement that healthy children are vaccinated in order to stop the spread of disease.
  • For families on a low income, schools should provide basic equipment such as pens, calculators and laptops.
  • Whilst school uniforms are expensive, they do provide security and a sense of belonging to students and for this reason, are an integral part of the school system.
  • Many public libraries are closing down due to lack of interest but these are important resources within the community and we should fight to keep them open.
  • With the internet becoming ever more popular and accessible to teenagers, cyber bullying is massively on the rise. A large number of cyber bullying cases end in suicide and it is down to parents and schools to tackle this growing problem.
  • Cannabis is not legal in many countries and states and this is for good reason. The drug is known to diminish the brain cells and regardless of how it might relax pain and anxiety, it should not be legalised.
  • Too many people are taking time of work for stress-related reasons and so it is more important than ever for workplaces to provide internal activities to combat this problem.
  • Many parents do not like the idea of their children being taught sex education at an early age but unfortunately in this day and age, it is a necessity if we want to keep children safe.

Avoiding Common Mistakes

When writing a thesis statement, it is essential to avoid common mistakes that may weaken your argument or confuse your reader. In this section, we will discuss two main pitfalls to avoid: Overgeneralizing and Using Weak or Vague Language.

Overgeneralizing

Overgeneralizing refers to making broad, sweeping claims in your thesis statement without providing specific, concrete evidence to support them. To avoid overgeneralization, focus on providing a clear and concise argument, grounded in solid research and evidence. Brainstorm specific examples or points you will address in your paper that support your thesis. For example, if your thesis is about a controversial topic, make sure your argument is based on valid research and takes a clear direction, rather than making generalized statements.

To prevent overgeneralization in your thesis statement:

  • Narrow the focus of your argument.
  • Ensure your claim is specific and backed up by evidence.
  • Be consistent with the goals and direction outlined in your paper.

Using Weak or Vague Language

Using weak or vague language in your thesis statement can result in a lack of clarity and create confusion for your reader. To maintain a strong, clear, and convincing thesis, avoid using weak or unclear terms, such as “interesting” or “might.” Instead, use assertive and definitive language that demonstrates your confidence and knowledge of the subject matter. For instance, if you are writing about a potential solution to a problem, make sure to express your stance in a strong, clear way to entice your reader and promise valuable insights.

To strengthen the language of your thesis statement:

  • Avoid using vague or ambiguous terms.
  • Use clear, specific language that directly communicates your argument.
  • Stay focused on your main points and the direction of your paper.

Keeping these tips in mind and utilizing clear language will contribute to a stronger, more effective thesis statement.

Crafting Engaging Introductions and Conclusions

Writing a hook.

A successful introduction begins with an attention-grabbing hook. A hook is an opening statement that piques the reader’s interest and encourages them to continue reading. There are various types of hooks, such as using a quote, posing a question, or stating an intriguing fact. The hook should be relevant to the topic and set the tone for the rest of the article.

Connecting Thesis Statement to Conclusion

The conclusion of an academic paper should restate the thesis statement and summarize the main points discussed in the body paragraphs. However, it’s important to do this in a way that doesn’t merely repeat the same information, but instead provides a sense of closure and emphasizes the significance of the topic.

One way to achieve this is by connecting the thesis statement to the conclusion through the use of topic sentences and counterarguments. A well-crafted topic sentence should introduce the main idea of a body paragraph, while a counterargument addresses potential objections to the thesis statement. Utilizing these elements effectively throughout the paper creates a sense of cohesion and allows for a smooth transition from the introduction to the conclusion.

By incorporating engaging hooks and thoughtfully connecting the thesis statement to the conclusion, the reader is more likely to be drawn into the article and appreciate the depth of the content presented.

Thesis Statement: Definition, Useful Tips and Examples of Thesis Statement

A thesis statement is made up of one or two sentences and gives the author the chance to tell the reader what the essay is going to be about as well as their stance on the topic. It should be clear and concise and should always tie in with the body paragraphs of the essay .

Whilst there are many points to consider when writing a thesis statement, a well-written one can answer a question and engage the reader in the essay. Sticking with the ‘rules’ of the thesis statement will allow the author to craft a well-written and relevant essay.

FAQs on Thesis Statement

What is a thesis statement.

A thesis statement is a sentence or two in an essay or research paper that presents the main argument or central idea of the paper. It tells the reader what to expect, guides the structure of the paper, and directly answers the question or topic being discussed.

How do I write a thesis statement?

There are four simple steps to write a thesis statement:

  • Start with a question : Identify the topic or question your paper will explore.
  • Write your initial answer : This should be a concise statement that provides a preliminary answer to the question.
  • Develop your answer : Expand on your initial answer by considering its implications, context, and evidence.
  • Refine your thesis statement : Revise and refine your statement to make it clear, specific, and arguable.

Where should the thesis statement be placed?

The placement of the thesis statement varies depending on the type of paper or essay. However, a common place for the thesis statement is at the end of the introduction paragraph, making it easier for the reader to identify the main argument early in the text.

What makes a good thesis statement?

A good thesis statement should be:

  • Clear : It should communicate your main point without confusion.
  • Specific : It should focus on a single topic or argument.
  • Arguable : It should present a claim that people can reasonably disagree on.
  • Relevant : It should relate to the purpose of the paper and contribute to its overall message.

What are the different types of thesis statements?

There are two main types of thesis statements:

  • Analytical : An analytical thesis breaks down an issue or idea into its component parts, evaluates the issue or idea, and presents the breakdown and evaluation to the audience.
  • Expository (explanatory) : An expository thesis explains something to the audience.

Remember, as you work on your thesis statement, keep the rest of your paper in mind to ensure that it aligns with the paper’s overall content and objective.

Frequently asked questions

Where does the thesis statement go in an essay.

The thesis statement should be placed at the end of your essay introduction .

Frequently asked questions: Writing an essay

For a stronger conclusion paragraph, avoid including:

  • Important evidence or analysis that wasn’t mentioned in the main body
  • Generic concluding phrases (e.g. “In conclusion…”)
  • Weak statements that undermine your argument (e.g. “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

Your essay’s conclusion should contain:

  • A rephrased version of your overall thesis
  • A brief review of the key points you made in the main body
  • An indication of why your argument matters

The conclusion may also reflect on the broader implications of your argument, showing how your ideas could applied to other contexts or debates.

The conclusion paragraph of an essay is usually shorter than the introduction . As a rule, it shouldn’t take up more than 10–15% of the text.

An essay is a focused piece of writing that explains, argues, describes, or narrates.

In high school, you may have to write many different types of essays to develop your writing skills.

Academic essays at college level are usually argumentative : you develop a clear thesis about your topic and make a case for your position using evidence, analysis and interpretation.

The “hook” is the first sentence of your essay introduction . It should lead the reader into your essay, giving a sense of why it’s interesting.

To write a good hook, avoid overly broad statements or long, dense sentences. Try to start with something clear, concise and catchy that will spark your reader’s curiosity.

Your essay introduction should include three main things, in this order:

  • An opening hook to catch the reader’s attention.
  • Relevant background information that the reader needs to know.
  • A thesis statement that presents your main point or argument.

The length of each part depends on the length and complexity of your essay .

Let’s say you’re writing a five-paragraph  essay about the environmental impacts of dietary choices. Here are three examples of topic sentences you could use for each of the three body paragraphs :

  • Research has shown that the meat industry has severe environmental impacts.
  • However, many plant-based foods are also produced in environmentally damaging ways.
  • It’s important to consider not only what type of diet we eat, but where our food comes from and how it is produced.

Each of these sentences expresses one main idea – by listing them in order, we can see the overall structure of the essay at a glance. Each paragraph will expand on the topic sentence with relevant detail, evidence, and arguments.

The topic sentence usually comes at the very start of the paragraph .

However, sometimes you might start with a transition sentence to summarize what was discussed in previous paragraphs, followed by the topic sentence that expresses the focus of the current paragraph.

Topic sentences help keep your writing focused and guide the reader through your argument.

In an essay or paper , each paragraph should focus on a single idea. By stating the main idea in the topic sentence, you clarify what the paragraph is about for both yourself and your reader.

A topic sentence is a sentence that expresses the main point of a paragraph . Everything else in the paragraph should relate to the topic sentence.

The thesis statement is essential in any academic essay or research paper for two main reasons:

  • It gives your writing direction and focus.
  • It gives the reader a concise summary of your main point.

Without a clear thesis statement, an essay can end up rambling and unfocused, leaving your reader unsure of exactly what you want to say.

Follow these four steps to come up with a thesis statement :

  • Ask a question about your topic .
  • Write your initial answer.
  • Develop your answer by including reasons.
  • Refine your answer, adding more detail and nuance.

A thesis statement is a sentence that sums up the central point of your paper or essay . Everything else you write should relate to this key idea.

An essay isn’t just a loose collection of facts and ideas. Instead, it should be centered on an overarching argument (summarized in your thesis statement ) that every part of the essay relates to.

The way you structure your essay is crucial to presenting your argument coherently. A well-structured essay helps your reader follow the logic of your ideas and understand your overall point.

The structure of an essay is divided into an introduction that presents your topic and thesis statement , a body containing your in-depth analysis and arguments, and a conclusion wrapping up your ideas.

The structure of the body is flexible, but you should always spend some time thinking about how you can organize your essay to best serve your ideas.

The vast majority of essays written at university are some sort of argumentative essay . Almost all academic writing involves building up an argument, though other types of essay might be assigned in composition classes.

Essays can present arguments about all kinds of different topics. For example:

  • In a literary analysis essay, you might make an argument for a specific interpretation of a text
  • In a history essay, you might present an argument for the importance of a particular event
  • In a politics essay, you might argue for the validity of a certain political theory

At high school and in composition classes at university, you’ll often be told to write a specific type of essay , but you might also just be given prompts.

Look for keywords in these prompts that suggest a certain approach: The word “explain” suggests you should write an expository essay , while the word “describe” implies a descriptive essay . An argumentative essay might be prompted with the word “assess” or “argue.”

In rhetorical analysis , a claim is something the author wants the audience to believe. A support is the evidence or appeal they use to convince the reader to believe the claim. A warrant is the (often implicit) assumption that links the support with the claim.

Logos appeals to the audience’s reason, building up logical arguments . Ethos appeals to the speaker’s status or authority, making the audience more likely to trust them. Pathos appeals to the emotions, trying to make the audience feel angry or sympathetic, for example.

Collectively, these three appeals are sometimes called the rhetorical triangle . They are central to rhetorical analysis , though a piece of rhetoric might not necessarily use all of them.

The term “text” in a rhetorical analysis essay refers to whatever object you’re analyzing. It’s frequently a piece of writing or a speech, but it doesn’t have to be. For example, you could also treat an advertisement or political cartoon as a text.

The goal of a rhetorical analysis is to explain the effect a piece of writing or oratory has on its audience, how successful it is, and the devices and appeals it uses to achieve its goals.

Unlike a standard argumentative essay , it’s less about taking a position on the arguments presented, and more about exploring how they are constructed.

You should try to follow your outline as you write your essay . However, if your ideas change or it becomes clear that your structure could be better, it’s okay to depart from your essay outline . Just make sure you know why you’re doing so.

If you have to hand in your essay outline , you may be given specific guidelines stating whether you have to use full sentences. If you’re not sure, ask your supervisor.

When writing an essay outline for yourself, the choice is yours. Some students find it helpful to write out their ideas in full sentences, while others prefer to summarize them in short phrases.

You will sometimes be asked to hand in an essay outline before you start writing your essay . Your supervisor wants to see that you have a clear idea of your structure so that writing will go smoothly.

Even when you do not have to hand it in, writing an essay outline is an important part of the writing process . It’s a good idea to write one (as informally as you like) to clarify your structure for yourself whenever you are working on an essay.

Comparisons in essays are generally structured in one of two ways:

  • The alternating method, where you compare your subjects side by side according to one specific aspect at a time.
  • The block method, where you cover each subject separately in its entirety.

It’s also possible to combine both methods, for example by writing a full paragraph on each of your topics and then a final paragraph contrasting the two according to a specific metric.

Your subjects might be very different or quite similar, but it’s important that there be meaningful grounds for comparison . You can probably describe many differences between a cat and a bicycle, but there isn’t really any connection between them to justify the comparison.

You’ll have to write a thesis statement explaining the central point you want to make in your essay , so be sure to know in advance what connects your subjects and makes them worth comparing.

Some essay prompts include the keywords “compare” and/or “contrast.” In these cases, an essay structured around comparing and contrasting is the appropriate response.

Comparing and contrasting is also a useful approach in all kinds of academic writing : You might compare different studies in a literature review , weigh up different arguments in an argumentative essay , or consider different theoretical approaches in a theoretical framework .

The key difference is that a narrative essay is designed to tell a complete story, while a descriptive essay is meant to convey an intense description of a particular place, object, or concept.

Narrative and descriptive essays both allow you to write more personally and creatively than other kinds of essays , and similar writing skills can apply to both.

If you’re not given a specific prompt for your descriptive essay , think about places and objects you know well, that you can think of interesting ways to describe, or that have strong personal significance for you.

The best kind of object for a descriptive essay is one specific enough that you can describe its particular features in detail—don’t choose something too vague or general.

If you’re not given much guidance on what your narrative essay should be about, consider the context and scope of the assignment. What kind of story is relevant, interesting, and possible to tell within the word count?

The best kind of story for a narrative essay is one you can use to reflect on a particular theme or lesson, or that takes a surprising turn somewhere along the way.

Don’t worry too much if your topic seems unoriginal. The point of a narrative essay is how you tell the story and the point you make with it, not the subject of the story itself.

Narrative essays are usually assigned as writing exercises at high school or in university composition classes. They may also form part of a university application.

When you are prompted to tell a story about your own life or experiences, a narrative essay is usually the right response.

The majority of the essays written at university are some sort of argumentative essay . Unless otherwise specified, you can assume that the goal of any essay you’re asked to write is argumentative: To convince the reader of your position using evidence and reasoning.

In composition classes you might be given assignments that specifically test your ability to write an argumentative essay. Look out for prompts including instructions like “argue,” “assess,” or “discuss” to see if this is the goal.

At college level, you must properly cite your sources in all essays , research papers , and other academic texts (except exams and in-class exercises).

Add a citation whenever you quote , paraphrase , or summarize information or ideas from a source. You should also give full source details in a bibliography or reference list at the end of your text.

The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .

An argumentative essay tends to be a longer essay involving independent research, and aims to make an original argument about a topic. Its thesis statement makes a contentious claim that must be supported in an objective, evidence-based way.

An expository essay also aims to be objective, but it doesn’t have to make an original argument. Rather, it aims to explain something (e.g., a process or idea) in a clear, concise way. Expository essays are often shorter assignments and rely less on research.

An expository essay is a common assignment in high-school and university composition classes. It might be assigned as coursework, in class, or as part of an exam.

Sometimes you might not be told explicitly to write an expository essay. Look out for prompts containing keywords like “explain” and “define.” An expository essay is usually the right response to these prompts.

An expository essay is a broad form that varies in length according to the scope of the assignment.

Expository essays are often assigned as a writing exercise or as part of an exam, in which case a five-paragraph essay of around 800 words may be appropriate.

You’ll usually be given guidelines regarding length; if you’re not sure, ask.

Thesis Statements

A thesis statement is a sentence (sometimes more than one sentence) in the introduction that tells the reader the following information:

  • What the topic of the paper is
  • How the writer intends to discuss that topic
  •  It gives a blueprint for how the essay will be structured
  •  How the writer intends to prove or demonstrate his or her main points.

Think of your paper as a human body, and your thesis statement as the spinal cord. Without it, there is no structure.

For you as the writer, the thesis statement:

Develops through the interrelationship of thinking, reading, and writing;

Limits your research by providing you with one controlling main idea that intrigues you;

Narrows your writing to one specific claim that you can develop or prove;

Organizes your ideas so you know the important points you want to make in your paper; and

Clarifies your writing by keeping you on target to fulfill your proposed purpose.

For your readers, the thesis statement:

 Identifies the main point and sub-points of your essay clearly and quickly;

Functions as a road map so your readers can easily follow your ideas; and

Gives satisfaction at the conclusion of the paper when your readers discover you have fulfilled your promise by proving or developing your main point.

Characteristics of Effective Thesis Statements

An effective thesis statement must be  factual and narrow.

An effective thesis statement prepares readers for facts and details, but it cannot itself be a fact. It must always be an inference that demands proof or further development. These proofs come from the literature. 

UNT Dallas campus has two buildings.

Not factual enough: The UNT Dallas campus is the perfect size.

Just Right:  While some might see small universities as a disadvantage, the small campus of UNT Dallas holds many advantages for students, including a close-knit campus community, smaller class sizes, and better support from professors.

2. Narrow Topic

A good thesis should be narrow, and not too broad or too vague. If the topic is too broad, you won’t be able to cover the entire topic in your paper.  If it’s too narrow, you might not be able to find research, and your paper probably won’t be long enough. 

Too Broad: College students have a lot of responsibilities.

Too Narrow: Student workers in the Learning Commons at UNT Dallas have many responsibilities in their course work and tutoring. 

Just Right: College students who are financially independent have many responsibilities as they must maintain good grades, pay living expenses, and balance work and school.

Remember, a thesis statement is not: 

  • Instead , you should argue, based on facts and literature, why or why not NASA should receive more funding.  
  • Ask yourself--can I find anything in literature to prove this point, or is this MY opinion? 
  • Instead, you should argue why or why not people like chocolate OR why or why not chocolate is healthy for you based on facts and literature findings. 
  • Similar to the subjective opinion, ask yourself is this statement is based on facts and literature findings or if this is YOUR opinion. Although it is ok to have your own opinion, professors usually do not like to read articles about beliefs (students have been writing about these for years and years). 
  • Instead, you could discuss theories about politics or religions and use literature to prove or disprove those theories.
  • This is too factual (the Himalayas WERE formed from a collision of tectonic plates), and there is nothing to discuss because this IS a fact in itself. 
  • Instead, you could compare and contrast the tectonic plate formation of different mountains. 

Examples of Thesis Statements

A thesis statement f or a 5 paragraph essay conta ins three parts:.

1. A Topic: the main idea of the essay

2. The Controlling Idea: what you want to say about the topic

3. The subtopics: usually 3 examples/reasons you will discuss in your paper

Here is an example  of a thesis statement.

Ex: Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.

The main topic explores the idea that regularly vsiting the writing center will help you become the best writer on the planet, and the subtopics further expand this opinion with three distinct examples: 1) tutors, 2) technology, and 3) the handouts.

Outline Example

The paper should be organized around the subtopics.  For example, for the thesis written above, the writer would write one body paragraph about the tutors, one about technology, and one about the handouts. 

Here is a sample essay outline based on this thesis:

  • Introduce the topic of tutoring
  • Thesis (last sentence of intro): Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.
  • topic sentence
  • Restate thesis
  • Concluding remarks

For further assistance with the structure, see our handouts on Introductions and Conclusions and Topic Sentences.

A thesis statement for a LONG ESSAY contains two parts: A Topic: the main idea of the essay The Controlling Idea: what you want to say about the topic 

Throughout the paper, your thesis promises your readers that you will prove specific facts or develop certain ideas ; therefore, every paragraph, sentence, and word in your paper must relate to this controlling idea.

Here are some examples of thesis statements.

  • Baseball, once a national pastime and even an addiction, has lost its popularity because of the new interest in more violent sports.
  • Since the space program has yet to provide the American people with any substantial, practical returns, it is a waste of money and should be dissolved.
  • To stop the alarming rise in the number of violent crimes committed every year, our courts must hand out tougher sentences.
  • Detective stories appeal to the basic human desire for thrills.
  • Hemingway's war stories helped to create a new prose style.
  • Bronte utilizes light and fire to symbolize the emotional expressions of the characters.

Here is a suggested outline for a long essay and how that would look in terms of your thesis statement, topic, and controlling ideas:

  • Introduce the novel Jane Eyre and the topic of symbolism
  • Thesis (last sentence of intro): Bronte utilizes light and fire to symbolize the emotional expressions of the characters.
  • textual examples and elaboration

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.

Thesis statement.

Definition:

The thesis is usually considered the most important sentence of your essay because it outlines the central purpose of your essay in one place. A good thesis will link the subject of an essay with a controlling idea. Consider, for example, the following thesis:

People in the past spent a great deal of effort protecting themselves from witches. Subject: people feared witches Controlling Idea: people spent a great deal of effort protecting themselves

In a short essay, a thesis statement appears at, or near, the end of the introductory paragraph of the paper so that readers know the topic of the essay before they see the writer's statement of the central purpose of the essay. This way the first paragraph helps the reader understand why the writer is writing.

A thesis should be narrow in focus in order to allow the fullest exploration of its issues as possible, and it should reflect the type of paper that follows, whether it be persuasive or informative. Narrowing the focus of the thesis may require posing questions about it to yourself before committing to a final version.

What follows is a method for writing thesis statements that many writers have found useful (we found it in Chapter 3 of The Allyn & Bacon Handbook ).

1. Decide what you are writing about:

A clear, concise thesis statement does more than outline the subject in question; it makes the reader aware of the writer's stand on the subject in question, connecting a subject with a controlling idea.

2. Think about all the elements your paper will deal with:

A thesis generally consists of a subject that contains within itself a number of smaller facts; the topic sentence of each paragraph that makes up the body of the paper should refer (in some clear way) back to the ideas contained within the thesis statement in order to keep the paper from digressing.

3. Think about the purpose and tone of your paper:

A thesis statement should contain the main point of the paper and suggest to the reader a direction that the paper will take in exploring, proving, or disproving that main point.

4. State your main point in a sentence or two:

A good writer can assert the main idea of a short, coherent essay briefly. Instead of rambling, be as straightforward as possible.

5. Revise your thesis as you develop your paper:

A final version of a thesis statement will only be available after a draft of the paper it is a part of has been completed. The focus of the paper may change and evolve over the period it is written in; necessarily, the thesis statement should be revised to reflect the alterations in the paper.

Few writers finish a paper writing about the exact topic they begin with. While you write a paper, your main point may change. As you're finishing, make sure your thesis statement has changed along with the subject and controlling ideas of your paper.

How to Write A thesis statement - Steps with Examples

A seasoned writer myself, I have watched so many students struggle to formulate a thesis statement. One sentence really the backbone of your paper has surprisingly been very tricky to perfect. No fears, though! I am here to guide you through the making process, sharing my experience and addressing you to a game-changing tool that will make magic transform your vague notions into thesis statements.

What is a thesis statement & What to include? 

Imagine the thesis statement to be the North Star of your paper. It is the one- or two-sentence declaration boldly announcing your main point or argument. It isn't a summary, but rather a mission statement of sorts for your paper to guide your reader through the twists and turns of your research or analysis.

Key Ingredients for a Killer Thesis Statement

An excellent thesis statement truly ought to have these elements:

The main idea or argument: This is what will propel the paper forward. It is, in effect, its heart. What are you attempting to prove, explain, or explore? Do not bury the lead—state it up front.

Specificity: Vagueness is the enemy of a good thesis. Get specific! Instead of saying, "Social media is bad," pinpoint exactly how it's detrimental.

Scope: Set the setting of your discussion. Are you dealing with a particular time period, demographic, or another aspect of your topic? Let your reader in on it.

Significance: So what? Why does your argument matter? Explain to your reader why they should care about your topic and your take on it, too.

Structure: Be concise and to the point. Try not to get no more than one or two sentences with real punch.

When all of these elements come together, you get a thesis statement that is not only informative but stimulating and attractive, beckoning your reader towards the rest in a paper.

Types of Thesis Statements

In academic writing, thesis statements fall under classes depending on the type of essay or paper being written. Knowing them can help in creating an emphatic and fruitful thesis statement.

Argumentative Essay

An argumentative thesis statement does indeed stand strong on a debated issue. This implies that it incorporates the author's position and the reasons, along with evidence supporting that position. This means convincing the reader that this is the right argument, together with supporting rationale and credible resources.

The impact of social media on adolescent mental health is devastating due to the rising cases of cyberbullying and body images that are unachievable. "

Expository Essay

On the other hand, the thesis statement for an expository essay aims to explain or describe the topic in a neutral way and is not argumentative. It provides the reader with a clear view of what the essay is going to talk about or analyze since it contains purely factual information, providing insight into the subject matter.

How to Write a Thesis Statement in 3 Steps [With Examples]

Setting a solid thesis statement doesn't have to be terrifying. Just break it down into three manageable steps:

Step 1: Identify the Topic and the Main Idea

Think of this as laying the groundwork for your thesis—what is the central subject you're going to be exploring, and what is your main point about it?

Example: If your chosen topic is "The Impact of Artificial Intelligence on Job Employment," then you would say your thesis is that AI will create new and destroy existing jobs.

Step 2: Craft Your Preliminary Thesis Statement

In this step, you'll write your initial draft of the thesis statement. Your reaction to the primary idea should be simple and logically evident.

Example: Original thesis: "Artificial intelligence is likely to create a huge impact in the job market, generating as well as putting people out of jobs at the same time."

Step 3: Revisioning and Refining Your Thesis Statement

Now you're ready to refine your thesis. Add detail, flesh out your language, and make it clear that it encompasses what you discuss in your paper.

Dawson-Snyder, Tanetta S., "Messaging the Mission: Developing and Implementing a Messaging Strategy for the Mission Statement of Monticello Christian Church" (2024). Doctoral Dissertations and Projects . 5867. https://digitalcommons.liberty.edu/doctoral/5867

This DMIN thesis project focuses on the inherent need to strategically message the mission statement of the Monticello Christian Church to its leaders, thus preparing them to relay it to the congregation for greater unity in fulfilling the misso Dei. With a focus on the educational training model, the study examines how the application of acquired knowledge empowers a church body to embrace a singular missional purpose. The training sessions were designed to help leaders utilize their cognitive and spiritual gifts to comprehend the depth and width of the missional message statement and adeptly communicate it to others. The research methods included training sessions on these topics and implementation phases in which the leaders were tasked with messaging the mission statement message and the missio Dei to the congregation. A research group of twelve leaders participated in the sessions. Qualitative evaluation measures utilizing inductive research models displayed successful fulfillment of the training sessions. The outcomes revealed new and essential information for future research and investigation into how missional messages are transmitted to congregations and the community. This project found inspiration from the Great Commission, the Great Commandment, and the missio Dei. The thesis explores how effective messaging strategies and collaboration among church leaders can influence the depth of knowledge and lead to increased unity under one mission purpose. It also delves into how effective communication strategies contribute to church growth, promote biblical and local missions, and foster unified efforts for the advancement of God’s Kingdom.

The latest sell-off may be the beginning of the end for the tech bubble, strategist says

  • The AI-fueled tech bubble could be approaching its end date, according to Paul Dietrich.
  • The market strategist pointed to similarities between the recent tech sell-off and the dot-com crash.
  • The economy also looks poised to enter a downturn, which will likely fuel more downside, he said.

Insider Today

The recent bloodbath in stocks might mark the beginning of the end of the artificial intelligence-fueled craze among investors.

Paul Dietrich, chief investment strategist of B. Riley Wealth Portfolio advisors, has been warning for months of an impending recession and stock market crash, particularly as enthusiasm for AI bleeds out of the market.

In a note on Tuesday, Dietrich said that his thesis has been bolstered by the recent sell-off sparked by weak economic data, which pushed the Nasdaq Composite into correction territory.

He pointed to the similarities between the dot-com crash and the latest drop in the stock market. Apple , which lost 79% of its total market value in the early 2000s, has dropped 8% over the past month. Amazon , which lost 93% of its total value in the dot-com era, has plunged 18% over the last month.

The flow of "smart money" in the market also suggests more downside could be on the way for tech stocks, Dietrich noted. He pointed to large stock sales initiated by tech CEOs, like Jeff Bezos, whose total sales of Amazon stock have totaled $13.5 billion so far this year. Meta CEO Mark Zuckerberg has sold off around $1 billion in company stock, while Nvidia CEO Jensen Huang has sold nearly half a billion worth of company shares so far this summer, according to securities filings.

"These investors do not think their companies are bad investments; they merely believe the stock market is currently valuing them far above their worth," Dietrich said. "I feel sorry for many average investors still piling into the stock market chasing the Artificial Intelligence (AI) hype and other tech stocks when many of those founders are selling out."

The economy, meanwhile, looks poised to enter a recession, Dietrich said, posing more bad news for stocks. Historically, stocks have declined 36% when the economy enters a recession, even if the downturn proves to be mild, Dietrich has said in previous notes.

He pointed to a slew of indicators that could suggest a downturn is on its way. Markets are coming off of one of the longest bull markets of all time, he noted. Corporate earnings have been "spotty." Interest rates in the economy remain at their highest levels since 2001. Meanwhile, the economy has triggered multiple recession warnings with near-perfect track records, like the yield curve inverting , and the unemployment rate rising past a key threshold typically associated with recessions.

"What kind of evidence does one need to see that we are moving into a business cycle recession," Dietrich said. "Eventually, we will have another long-term bear market recession."

Though he didn't have an exact prediction for when a downturn could strike, Dietrich said the economy could start entering a mild recession by the end of the year. That could fuel as much as a 40% downside in the S&P 500, he predicted, pointing to historical losses in the stock market when the economy entered a recession.

Recession fears spiked last week after the job market was found to slow more than expected in the month of July, fueling concerns that the Fed may have made a mistake keeping interest rates too-high for too-long. Investors are ramping up bets for steep rate cuts and even an emergency rate cut by the end of the year, a move central bankers have typically only employed during times of extreme volatility.

Dark Matter Flies Ahead of Normal Matter in Mega Galaxy Cluster Collision

Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter. The two clusters each contain thousands of galaxies and are located billions of light-years away from Earth. As they plowed through each other, the dark matter—an invisible substance that feels the force of gravity but emits no light—sped ahead of the normal matter. The new observations are the first to directly probe the decoupling of the dark and normal matter velocities.

Galaxy clusters are among the largest structures in the universe, glued together by the force of gravity. Only 15 percent of the mass in such clusters is normal matter, the same matter that makes up planets, people, and everything you see around you. Of this normal matter, the vast majority is hot gas, while the rest is stars and planets. The remaining 85 percent of the cluster mass is dark matter.

During the tussle that took place between the clusters, known collectivity as MACS J0018.5+1626, the individual galaxies themselves largely went unscathed because so much space exists between them. But when the enormous stores of gas between the galaxies (the normal matter) collided, the gas became turbulent and superheated. While all matter, including both normal matter and dark matter, interacts via gravity, the normal matter also interacts via electromagnetism, which slows it down during a collision. So, while the normal matter became bogged down, the pools of dark matter within each cluster sailed on through.

Think of a massive collision between multiple dump trucks carrying sand, suggests Emily Silich, lead author of a new study describing the findings in The Astrophysical Journal . "The dark matter is like the sand and flies ahead." Silich is a graduate student working with Jack Sayers, research professor of physics at Caltech and principal investigator of the study.

The discovery was made using data from the Caltech Submillimeter Observatory (which was recently removed from its site on Maunakea in Hawai‘i and will be relocated to Chile), the W.M. Keck Observatory on Maunakea, NASA's Chandra X-ray Observatory, NASA's Hubble Space Telescope, the European Space Agency's now-retired Herschel Space Observatory and Planck observatory (whose affiliated NASA science centers were based at Caltech's IPAC), and the Atacama Submillimeter Telescope Experiment in Chile. Some of the observations were made decades ago, while the full analysis using all the datasets took place over the past couple of years.

Such decoupling of dark and normal matter has been seen before, most famously in the Bullet Cluster . In that collision, the hot gas can be seen clearly lagging behind the dark matter after the two galaxy clusters shot through each other. The situation that took place in MACS J0018.5+1626 (referred to subsequently as MACS J0018.5) is similar, but the orientation of the merger is rotated, roughly 90 degrees relative to that of the Bullet Cluster. In other words, one of the massive clusters in MACS J0018.5 is flying nearly straight toward Earth while the other one is rushing away. That orientation gave researchers a unique vantagepoint from which to, for the first time, map out the velocity of both the dark matter and normal matter and elucidate how they decouple from each other during a galaxy cluster collision.

"With the Bullet Cluster, it's like we are sitting in a grandstand watching a car race and are able to capture beautiful snapshots of the cars moving from left to right on the straightaway," says Sayers. "In our case, it's more like we are on the straightaway with a radar gun, standing in front of a car as it comes at us and are able to obtain its speed."

To measure the speed of the normal matter, or gas, in the cluster, researchers used an observational method known as the kinetic Sunyaev-Zel'dovich (SZ) effect. Sayers and his colleagues made the first observational detection of the kinetic SZ effect on an individual cosmic object, a galaxy cluster named MACS J0717, back in 2013, using data from CSO (the first SZ effect observations taken of MACS J0018.5 date back to 2006).

The kinetic SZ effect occurs when photons from the early universe, the cosmic microwave background (CMB), scatter off electrons in hot gas on their way toward us on Earth. The photons undergo a shift, called a Doppler shift , due to the motions of the electrons in the gas clouds along our line of sight. By measuring the change in brightness of the CMB due to this shift, researchers can determine the speed of gas clouds within galaxy clusters.

"The Sunyaev-Zeldovich effects were still a very new observational tool when Jack and I first turned a new camera at the CSO on galaxy clusters in 2006, and we had no idea there would be discoveries like this," says Sunil Golwala, professor of physics and Silich's faculty PhD advisor. "We look forward to a slew of new surprises when we put next-generation instruments on the telescope at its new home in Chile."

By 2019, the researchers had made these kinetic SZ measurements in several galaxy clusters, which told them the speed of the gas, or normal matter. They had also used Keck to learn the speed of the galaxies in the cluster, which told them by proxy the speed of the dark matter (because the dark matter and galaxies behave similarly during the collision). But at this stage in the research, the team had a limited understanding of the orientations of the clusters. They only knew that one of them, MACS J0018.5, showed signs of something strange going on—the hot gas, or normal matter, was traveling in the opposite direction to the dark matter.

"We had this complete oddball with velocities in opposite directions, and at first we thought it could be a problem with our data. Even our colleagues who simulate galaxy clusters didn't know what was going on," Sayers says. "And then Emily got involved and untangled everything."

For part of her PhD thesis, Silich tackled the conundrum of MACS J0018.5. She turned to data from the Chandra X-ray Observatory to reveal the temperature and location of the gas in the clusters as well as the degree to which the gas was being shocked. "These cluster collisions are the most energetic phenomena since the Big Bang," Silich says. "Chandra measures the extreme temperatures of the gas and tells us about the age of the merger and how recently the clusters collided." The team also worked with Adi Zitrin of the Ben-Gurion University of the Negev in Israel to use Hubble data to map the dark matter using a method known as gravitational lensing .

Additionally, John ZuHone of the Center for Astrophysics at Harvard & Smithsonian helped the team simulate the cluster smashup. These simulations were used in combination with data from the various telescopes to ultimately determine the geometry and evolutionary stage of the cluster encounter. The scientists found that, prior to colliding, the clusters were moving toward each other at approximately 3000 kilometers/second, equal to roughly one percent of the speed of light. With a more complete picture of what was going on, the researchers were able to figure out why the dark matter and normal matter appeared to be traveling in opposite directions. Though the scientists say it's hard to visualize, the orientation of the collision, coupled with the fact that dark matter and normal matter had separated from each other, explains the oddball velocity measurements.

In the future, the researchers hope that more studies like this one will lead to new clues about the mysterious nature of dark matter. "This study is a starting point to more detailed studies into the nature of dark matter," Silich says. "We have a new type of direct probe that shows how dark matter behaves differently from normal matter."

Sayers, who recalls first collecting the CSO data on this object almost 20 years ago, says, "It took us a long time to put all the puzzle pieces together, but now we finally know what's going on. We hope this leads to a whole new way to study dark matter in clusters."

The study titled " ICM-SHOX. Paper I: Methodology overview and discovery of a gas–dark matter velocity decoupling in the MACS J0018.5+1626 merger ," was funded by the National Science Foundation, the Wallace L. W. Sargent Graduate Fellowship at Caltech, the Chandra X-ray Center, the United States-Israel Binational Science Foundation, the Ministry of Science & Technology in Israel, the AtLAST (Atacama Large Aperture Submillimeter Telescope) project, and the Consejo Nacional de Humanidades Ciencias y Technologías.

This artist's concept depicts a collision between two massive clusters of galaxies.

This poem excerpt, written by Emily Silich, a Caltech graduate student in astronomy, was inspired by her studies of collisions between massive clusters of galaxies. In fact, she wrote it during the many hours while her analysis of simulations of galaxy cluster collisions ran on hundreds of computer cores.

The full poem was published as part of a collection in the Altadena Poetry Review Anthology .
