Building a Strong Thesis

A thesis is a claim that needs to be argued — not just a fact or a topic statement.

~25 minutes

📌 Before You Start

What you need:

Claude open in another tab (claude.ai)
A paper angle or topic in mind (from Module 2, or your own)
Something to write your thesis drafts in — even a scrap of paper

Goal: Write or revise a real thesis statement for a paper you’re working on, and use AI to stress-test it.

💡 The Big Idea

A weak thesis is the single biggest reason professors give papers a C instead of a B.

Here’s what most students write as a “thesis”:

❌ “Social media has changed communication.” (This is a fact, not an argument.)

❌ “Climate change is an important issue.” (Nobody disagrees with this.)

✅ “Social media’s emphasis on brief, visual content has degraded the quality of public political discourse by rewarding outrage over nuance.” (This is arguable. Someone could push back.)

✅ “The community college transfer system in California disadvantages first-generation students because major preparation requirements are inconsistently communicated across campuses.” (Specific. Arguable. Sets up a paper.)

Two tests every thesis must pass:

Test 1: The “So What?” Test

After you write your thesis, ask: “So what? Why does this matter? Who should care?” If you can’t answer that, your thesis isn’t strong enough yet.

Test 2: The “Someone Could Disagree” Test

Can a reasonable person read your thesis and say “I’m not sure that’s right” or “that’s a stretch”? If yes, it’s arguable. If everyone agrees automatically, it’s a fact — not a thesis.

Thesis evolution: Your first thesis draft will be weak. That’s normal and fine. The goal is to go from rough → refined → final. AI feedback is useful at every stage of this process.

Where to put your thesis: In most college essays, the thesis goes at the end of your introduction. But different disciplines have different conventions — in some fields, you state your findings upfront; in others, you build to your argument. When in doubt, ask your professor or check past papers in your field.

🤖 AI in Action

Prompt 1 — Evaluate my thesis:

📋 Copy this prompt into Claude:

Here is my thesis statement: "[paste thesis]" This is for a [type of paper] about [topic] for [class]. Please evaluate it using these criteria: 1. Is it specific or too vague? 2. Is it arguable, or is it just a fact? 3. Does it tell the reader what to expect in the paper? 4. How could I make it stronger?

This gives you structured feedback instead of vague comments. The four criteria map directly to how most professors evaluate thesis statements.

Prompt 2 — Strengthen my thesis:

📋 Copy this prompt into Claude:

My current thesis is: "[paste thesis]" Give me 3 stronger versions of this thesis. Make each one more specific and more arguable than the original. Explain what you changed and why.

Important: Don’t just copy Claude’s improved thesis. Read the three versions, understand why they’re stronger, and then write your own version that sounds like you and matches your actual argument.

🛑 Good stopping point. The “Your Turn” section below is the most important part of this module — it’s where real learning happens.

🖐️ Your Turn

Task: Write your current thesis (or draft one for a paper). Run it through Prompt 1 above.

Write your current thesis — even if it’s rough. Just write something.
Run Prompt 1 with your thesis. Read Claude’s feedback carefully.
Choose one specific suggestion from Claude and revise your thesis.
Write both versions side by side: Before and After.
In one sentence, note what changed and why it’s an improvement.

The revision step is yours. Claude identifies the problem — you make the judgment call about how to fix it. Your thesis needs to match your actual argument, not a generic strong thesis.

🧠 Brain Break

Think about a time someone told you a fact that wasn’t interesting, versus a time someone said something that made you think “wait, really?”

That “wait, really?” reaction is what a good thesis should create in your reader. Not shock — just enough surprise that they want to read on to see if you can back it up.

✅ Key Takeaways

A thesis is a claim that needs to be argued — not a fact, not a topic sentence.
Use the “So What?” test and the “Someone Could Disagree” test on every thesis you write.
AI can evaluate your thesis against clear criteria — use that feedback to revise, not to copy.
A weak thesis early in the writing process leads to a structureless paper. Fix it before you outline.
Your first thesis is always rough. The revision process is where the real thesis gets made.
