ChatGPT Critical Thinking: How to Strengthen Your Reasoning With AI

Key takeaways

ChatGPT can be a powerful tool for strengthening your critical thinking if you know how to use it.

• An MIT Media Lab study found that participants who used ChatGPT to write essays showed lower cognitive engagement and memory retention than those who did not use the AI [1].

• Accepting prefabricated answers rather than working through the reasoning yourself can weaken your ability to think independently, according to a study published in 2025 [2].

• You can build stronger reasoning habits by questioning ChatGPT's responses, pushing back on its reasoning, and asking what it left out.

Learn how to use ChatGPT to strengthen your critical thinking, not replace it. If you're ready to sharpen your prompting skills, enroll in the Vanderbilt University Prompt Engineering Specialization. You'll have the opportunity to explore how to write instructions for large language models (LLMs), such as ChatGPT, and build skills through hands-on projects. Upon completion, you will have a shareable certificate.

How ChatGPT affects critical thinking

How you use ChatGPT largely determines what it does to your thinking. When you use it to debate a position, stress-test a claim, or examine a topic from multiple angles, the interaction can deepen your engagement with ideas and push you to think more actively. When you step back and let it do the work, the creative and critical decisions shift to the AI.

The pattern of letting a large language model (LLM) do the work for you has a name: cognitive offloading. Accepting prefabricated answers rather than working through the reasoning yourself reduces your cognitive engagement with ideas over time. An  MIT Media Lab study tracked this pattern. The individuals in the study who relied on ChatGPT to write their essays showed the weakest neural activity, which indicated low brain engagement [1].

Part of what makes the reliance easy to accept is how ChatGPT presents information. It can generate detailed, confident-sounding responses on almost any topic, and its confidence can lead you to stop questioning what it tells you and accept it as a finished product.

What is the MIT ChatGPT study?

A study conducted by MIT Media Lab divided 54 participants into three groups: one using ChatGPT, one using a search engine, and one using only their brains. Researchers then tracked the brain activity of each group with electroencephalography (EEG) in multiple sessions. Across neural, linguistic, and behavioral measures, the group using ChatGPT consistently underperformed [1].

How to use ChatGPT to strengthen critical thinking

A peer-reviewed study found that debate students who posed follow-up questions, challenged the tool's responses, and used it to generate counterarguments to their own positions showed significant improvements in critical thinking and argumentation skills compared to those who used traditional debate methods without the use of AI [3]. The back-and-forth interaction keeps you in the reasoning process. Take this exchange as an example.

Prompt: Should I go back to school to advance my career?

ChatGPT: It depends on your goal. Going back to school can be valuable, but it's not automatically the right move. Consider whether a degree is actually required in your field, what the return on investment looks like, and whether faster alternatives like certifications or online programs might get you there instead.

Follow-up: You assumed my goal is career advancement. What if my real goal is to switch industries entirely?

ChatGPT: That changes the answer significantly. Switching industries makes school more likely to be worth it, especially if the new field is credential-gated, like health care, law, or certain finance roles. If the field is skill-based and open-entry, like tech or marketing, a portfolio and targeted experience may still get you further faster.

Follow-up: What did you leave out?

ChatGPT: Quite a bit. I oversimplified the alternatives: building a portfolio or networking into a role sounds straightforward, but both require discipline and tolerance for uncertainty that I didn't acknowledge. I also didn't address opportunity cost fully: two years in school means two years not gaining real-world experience, which in fast-moving fields can matter more than the credential.

Each follow-up reveals something the previous response missed.

ChatGPT critical thinking prompts

Using these prompts effectively means treating ChatGPT as the start of a conversation, not the end of one. When a response feels complete, that's often the moment to push further. Ask what it left out. Request a stronger counterargument. Have it identify the weakest point in its own reasoning. The prompts below give you specific language for each of these, but the underlying move is the same: you are part of the reasoning process.

• To challenge your assumptions: I believe [your position]. Identify the top assumptions behind this belief and challenge each one with an alternative perspective.

• To stress-test your reasoning: I believe [your claim] based on [your evidence]. Evaluate the strength of this reasoning. What alternative explanations could account for the same evidence? What would weaken my conclusion?

• To explore counterarguments: I strongly believe [your position]. Argue the opposing view as if you genuinely hold it. Do not concede to my pushback. Explain the flaws in my thinking.

• To analyze a source or claim: Evaluate this argument: [paste argument or claim]. What assumptions does it rely on? Where is the reasoning strong, and where does it break down?

• To examine multiple perspectives: Give me three distinct perspectives on [topic], including one I am unlikely to have considered. Then tell me what evidence would support or undermine each one.

• To deepen your understanding of a complex topic: Explain [concept or topic]. Then tell me what is contested or uncertain about it, and where experts tend to disagree.

• To reflect on your own thinking: I just reached this conclusion: [your conclusion]. What cognitive biases might have influenced how I got here? What would a skeptic say about my reasoning?

What is a ChatGPT critical thinking test?

MIT digital fellow Hal Gregersen developed the Question Burst Catalyst, a tool designed to use ChatGPT to help you ask better questions rather than seek better answers. The tool walks you through four steps: describe a problem, create your own questions, assign the AI a persona, and compile the results into an action plan. The goal is to shift the AI's focus from giving you agreeable answers to deepening your thinking [4]. You can find the Question Burst Catalyst as a custom GPT in ChatGPT [5].
