How ChatGPT Affects Cognitive Abilities: What MIT Researchers Discovered
ChatGPT has become a daily tool for many people, helping with emails, brainstorming, and learning. But is it making us think less critically?
Researchers at MIT (Massachusetts Institute of Technology) recently conducted a study to see how using ChatGPT affects reasoning and cognitive skills in real tasks.

Does ChatGPT Improve or Hurt Critical Thinking?
What Was the Study About?
The MIT team asked 500+ participants to complete reasoning tasks, such as explaining decisions or solving hypothetical scenarios, with and without ChatGPT assistance.
Some participants wrote and revised their answers manually, while others were allowed to use ChatGPT to generate, edit, or directly copy responses.
Does ChatGPT Improve or Hurt Critical Thinking?
Here’s what the researchers found:
✅ Participants using ChatGPT produced longer and more structured responses, often with clearer arguments.
✅ However, answer diversity and originality decreased, especially when people simply copied ChatGPT’s responses without much reflection.
✅ Those who used ChatGPT but revised and analyzed its output maintained higher levels of critical thinking.
In other words, ChatGPT can help you express ideas better, but it might reduce deeper thinking if you rely on it passively.
The researchers warned that heavy reliance on ChatGPT may reduce active cognitive engagement, especially in repetitive tasks.
When we consistently outsource our reasoning to AI without questioning or analyzing it, we risk weakening critical and creative thinking over time.

How to Use ChatGPT Without Harming Your Brain
ChatGPT is a powerful learning and productivity tool, but it should be used wisely:
✔ Try solving problems on your own first.
✔ Use ChatGPT to get alternative perspectives or structure your thoughts.
✔ Edit, question, and expand upon its suggestions.
✔ Treat ChatGPT as a thinking partner, not a replacement for thinking.
This way, you can enhance your cognitive skills while benefiting from AI assistance.
