ChatGPT Prompts for Critical Thinking: 12 Argument Drills

ChatGPT prompts for critical thinking work best when they make you do the thinking and use the chatbot as a sparring partner. Paste a real argument, ask for questions before answers, and make the model quote the exact sentence behind every problem it names. The 12 prompts below cover analyzing arguments, checking claims, arguing the other side, and training your own habits.

Take an argument apart

1. Claim map

Here is an argument: [paste]. State the main claim in one sentence, then list each reason with the exact sentence it comes from. Do not judge it yet.

2. Assumption finder

For each reason in this argument, write the unstated assumption that has to be true for the reason to support the claim, phrased as something I could test: [paste].

3. Fallacy check with proof

Check this passage for reasoning flaws: [paste]. Name a flaw only if you can quote the sentence that commits it and explain why in one line. If a sentence is weak but not a named fallacy, say so.

4. Evidence ladder

Sort the support in this argument from weakest to strongest (personal story, unnamed example, expert opinion, data with a source) and say what would move each one up a rung: [paste].

Check claims and sources

5. Lateral reading plan

I found this claim on [site or account]: [claim]. List what I should look up about the source itself before trusting it, and which kinds of independent sources could confirm or contradict it.

6. Number sanity check

This article says [statistic]. Ask me the questions I need to answer about it: compared to what, out of how many, over what time, and measured by whom.

7. Headline versus article

Here is a headline and the article under it: [paste]. Does the body support the headline's wording? Quote the closest supporting sentence and point out any gap.

Argue the other side

8. Steelman

I believe [position]. Write the strongest case against it as its smartest supporter would, in one paragraph, without straw men or insults.

9. Three-round debate

Debate me on [question]. You take [side]. Give one opening point, wait for my reply, rebut it, and after three rounds score both sides on evidence and logic, not on who sounds confident.

10. Stakeholder swap

For the proposal [describe], list three groups it affects and the best argument each would make, then one question each group would want answered first.

Train your own habits

11. Socratic tutor

Act as a Socratic tutor on [topic or reading]. Ask me one question at a time, never give the answer, and push back when my reply skips a step.

12. Decision pre-mortem

I plan to [decision]. Imagine it is a year from now and the decision went badly. List the most likely reasons, the warning signs I could watch for, and one thing to check before I commit.

Worked example

An 11th grader in AP Language had to evaluate a letter to the editor arguing that Riverton should ban gas-powered leaf blowers. The letter's support was one noisy neighbor, a claim that "several cities" had bans "so clearly the bans work", a swipe at opponents, and the line that electric blowers are cheap so landscapers face "no real cost". The student agreed with a ban but could not explain why the letter felt weak.

In coach mode, the flagship prompt opened with five Socratic questions, then an answer key: a claim map with four reasons, the hidden assumption under each, a hasty generalization in the neighbor story, a non sequitur in "already banned, so clearly the bans work", an ad hominem against opponents, and an unsupported cost claim. It wrote a steelman for small landscaping crews, warned the student that agreeing with the ban could make the neighbor story feel stronger than it is, and rewrote the cost paragraph with brackets where real quotes should go. Run the full critical thinking argument check prompt on your own reading.

Variations

• Your own essay: switch to check mode and paste your draft to find the weakest reason before a peer review.
• Ads and product pages: ask which claims are measurable and which are only feelings.
• Group work: give each student a different stakeholder from prompt 10 and compare answers.

Practical tips

• Paste the full text. A summary already contains someone's interpretation.
• Write your answer to each Socratic question before asking for the key.
• If the model names a fallacy, ask it to quote the sentence. Labels without quotes are often wrong.
• Check your school's rules on AI use and keep the final analysis in your own words.
