Building a Strong Thesis
A thesis is a claim that needs to be argued — not just a fact or a topic statement.
~25 minutesWhat 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.
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”:
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.
Prompt 1 — Evaluate my thesis:
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:
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.
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.
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.
2 minutes away from the screen. Then come back for the 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.
