Let’s get started!

How to Write a Strong Thesis Statement

What Is a Thesis Statement?

A thesis statement is a 1-2 sentence claim that presents the main argument or central message of your essay or research paper.

It serves two core purposes:

1. To guide the writer. The thesis provides a “roadmap” that determines how to logically structure your paper and develop supporting points.

2. To guide the reader. The thesis signals what your essay will cover and provides context for your evidence and analysis.

In other words, the thesis statement both anchors the essay and anticipates the content to come.

What Is a Thesis Statement?

Strong thesis statements share several key characteristics:

• Specificity: They zero in on a focused, narrow claim rather than a broad, generic topic.

• Arguability: They make a claim that can be supported and debated with evidence.

• Clarity: They use clear, precise language to present the argument.

• Relevance: They directly address the prompt or assignment guidelines.

Let’s look at some examples of strong thesis statements:

• Argumentative: “School uniforms should be mandatory for all public school students because they promote equality, school spirit, and discipline in the classroom.”

• Expository: “The process of cell division consists of four main phases: prophase, metaphase, anaphase, and telophase.”

• Analytical: “In Arthur Miller’s play Death of a Salesman, the character of Willy Loman is a tragic hero who remains unable to separate illusion from reality.”

Now that you know the core components of an effective thesis statement, let’s walk through the step-by-step process for crafting one.

How to Write a Strong Thesis Statement in 7 Steps

Follow this proven blueprint to develop a rock-solid thesis statement that provides direction and establishes credibility:

Step 1: Analyze the Assignment Prompt

Start by carefully reading the essay or paper prompt. Identify the following elements:

• The primary question or problem you’re being asked to address.
• Any specific instructions related to the thesis (length, stance required, etc).
• Key factors like the essay type (argumentative, analytical, etc.) and required sources.

Underline or highlight the prompt’s core question. This will drive your research and inform your thesis.

Step 2: Brainstorm and Narrow Your Focus

Based on the prompt, brainstorm broader topics and potential angles related to the question at hand.

Next, strategically narrow your focus to home in on a specific, manageable topic for your paper. Ask yourself:

• What specific issue, solution, phenomenon, or process will I tackle?
• Are there any constraints I should consider (page length, timeline, access to sources)?
• Can I reasonably address this within the parameters of the assignment?

A narrowed topic will give you a clear direction for research.

Step 3: Formulate a Research Question

Take your narrowed topic focus and turn it into an open-ended research question.

This question will guide your investigation and serve as the basis for your thesis statement.

Make sure your research question:

• Focuses on an unresolved issue or gap in understanding.
• Uses interrogative language (“How”, “Why”, “Should”, etc).
• Cannot be answered with a simple yes/no or facts alone.

For example, if your narrowed topic is renewable energy, your research question could be, “How can cities increase the adoption of renewable energy sources?”

Step 4: Conduct Preliminary Research

Conduct preliminary research on your question, taking notes on key findings, statistics, and potential arguments.

This will allow you to map out the scope of available evidence and determine a specific direction for your thesis statement and paper.

Step 5: Draft a Working Thesis Statement

Synthesize your research to draft a working 1-2 sentence thesis statement presenting your initial argument or position on the research question.

Make sure your working thesis:

• Presents an arguable, supportable claim, not a fact or observation.
• Uses clear, direct language free of vagueness.
• Aligns with the type of essay you are writing (argumentative, analytical, etc.)

Example working thesis: “Cities should implement a portfolio of incentives and regulations to accelerate mass adoption of renewable energy sources like solar power.”

Step 6: Revise for Clarity, Specificity, and Strength

It’s rare to craft a great thesis statement on the first try. You will likely need to revise your working thesis multiple times.

Ask yourself these key questions:

• Is my claim specific and focused enough?
• Does it establish a clear position on my research question?
• Is it directly relevant to my prompt and research focus?
• Is there any ambiguity I need to resolve?
• Is this thesis debatable and defendable within the scope of my essay?

Strengthen vague claims by making them more precise. Cut out any tangents unrelated to your research question and prompt.

Step 7: Align with Essay Structure and Outline

Your thesis statement should align logically with the structure and flow of your essay. Make sure it lays the foundation for what’s to come.

• For argumentative essays, it should foreshadow your key arguments.

• For analytical essays, it should preview the components you will analyze.

• For expository essays, it should introduce the process or information you will explain further.

With your thesis in place, outline your paper to ensure your content flows logically and supports your central claim.

By taking it step-by-step and revising along the way, you can craft a thesis statement that checks all the boxes—specificity, arugability, clarity, and strength.

Now let's look at common pitfalls to avoid.

Thesis Statement Issues: 4 Pitfalls and Solutions

Even experienced writers struggle with crafting effective thesis statements. Here are four of the most common issues, along with ways to fix them:

1. Vagueness

The thesis makes an overly broad, generic claim that lacks focus.

How to improve: Pinpoint a specific argument and avoid words like “aspects”, “issues”, “ideas”.

Example:

Weak: “Social media affects human behavior.”

Stronger: “The ‘like’ feature on social media promotes negative social comparison and low self-esteem among teenagers.”

2. Lack of Arguability

The thesis simply states a fact, definition, or observation.

How to improve: Take a clear stance that can be argued based on evidence. Present an interpretation, not just information.

Example:

Weak: “Climate change is causing sea levels to rise worldwide.”

Stronger: “Coastal cities need to implement stronger climate change policies, including carbon pricing, to mitigate rising sea levels over the next century.”

3. Overly Broad Scope

The thesis attempts to accomplish too much, going beyond the boundaries of the assignment.

How to improve: Narrow your focus to something manageable within the length and purpose of the essay.

Example:

Weak: “Human activity is responsible for climate change.”

Stronger: “Methane emissions from livestock farming have substantially contributed to climate change.”

4. Disconnection from Prompt

The thesis is vague, broad, or unrelated to the specific assignment guidelines.

How to improve: Carefully re-read the prompt and tailor your thesis to directly address its core question and constraints.

Refining Your Thesis: Review, Feedback, and Revision

Your thesis statement is not set in stone! Plan to refine and revise it throughout the writing process:

Review for Alignment

As you write your essay body, continually refer back to your thesis to ensure your content aligns. Adjust as needed.

Solicit Feedback

Ask peers, instructors, and tutors to evaluate your thesis statement. Get an outside perspective on its clarity and persuasiveness.

Refining Your Thesis: Review, Feedback, and Revision

Revise Accordingly

Use feedback to strengthen weaknesses in your thesis and polish the wording. Refining as you draft will improve essay coherence.

Approach your thesis statement as a work in progress. Revision is key to crafting an accurate, specific, defensible claim that adds credibility to your academic writing.

Thesis Statements by Essay Type

Thesis statements will vary somewhat depending on the type of essay you are writing. Let’s look at the nuances:

Argumentative Essay Thesis Statements

Argumentative essays attempt to persuade readers to agree with a debatable opinion, recommendation, or solution. Here are two examples:

• Weak: "Standardized testing should be changed."
• Stronger: “States should eliminate high-stakes standardized testing in public schools and instead prioritize teacher-developed assessments."

Tips:

• Take a clear position that readers can argue against.
• Use strong, decisive language (e.g., “should”, “needs to”, “must”).

Expository Essay Thesis Statements

Expository essays explain information, facts, processes, or ideas. The thesis establishes the focus of the explanation.

• Weak: “This essay will explain photosynthesis.”
• Stronger: “Photosynthesis is the process plants use to convert sunlight, carbon dioxide, and water into food and oxygen.”

Tips:

• Introduce the topic being explained.
• Use language like “is defined as” or “consists of”.

Analytical Essay Thesis Statements

Analytical essays break down and examine a concept, text, event, etc. The thesis sets up the scope of analysis.

• Weak: “This essay will analyze Shakespeare’s use of foreshadowing.”
• Stronger: “William Shakespeare uses foreshadowing in Romeo and Juliet to warn readers about the tragic fate of the young lovers.”

Tips:

• State what is being analyzed and the lens of analysis.
• Take a stance on the significance of what you examine.

Thesis Statements by Essay Type

Thesis Statement Examples

Let's look at a few more examples of strong thesis statements across essay types:

• Argumentative: “The internet’s potential to radicalize at-risk individuals requires social media companies to take more aggressive efforts to remove extremist content from their platforms.”

• Expository: “The training process to become a firefighter EMT involves earning an EMT certification, completing a firefighter training academy, passing physical tests, training onsite, and completing probationary periods.”

• Analytical: “Through the juxtaposition of the bookish, idealistic Elizabeth to the pragmatic, earthy Charlotte in Pride and Prejudice, Jane Austen crafts a nuanced portrayal of womanhood in Regency-era England."

Remember, a strong thesis serves as the backbone for the entire essay—take your time crafting and refining it. Your effort will pay off with improved focus, direction, and strength of analysis.

FAQ

Still have questions about crafting great thesis statements? Here are answers to some frequently asked questions:

Q: How specific should my thesis statement be?

A: Strive for maximum specificity while still keeping your thesis flexible enough that your arguments/analysis can develop over the course of writing. Find the focused “sweet spot” between overly broad and overly narrow.

Q: Where in my essay should the thesis statement go?

A: In standard academic essays, the thesis typically appears at the end of the introduction paragraph and establishes the focus for everything to follow. This may vary for certain essay genres, so follow your assignment guidelines.

Q: Can my thesis statement be more than one sentence?

A: We recommend 1-2 sentences maximum. A concise, targeted thesis statement improves the coherence and direction of your paper. If you find yourself going beyond two sentences, you may need to narrow your focus further.

Q: How can I tell if my thesis is arguable enough?

A: Try asking peers or professors if they would challenge or debate your thesis based on available evidence. A strong, arguable thesis elicits more discussion than agreement; it shouldn’t be easily provable in a few sentences.

Q: Should I avoid first-person pronouns (I, me) in my thesis?

A: Using first-person can undermine the objectivity of academic writing. But exceptions can be made for certain assignments and paper types. When in doubt, check the guidelines or ask your instructor.
