Use it or lose it.

Every tool that thinks for you saves a little effort. Saved effort leads to mental atrophy.

Strength you don’t use fades. At the gym, everybody knows it. With your mind, it’s easy to forget, until the day you reach for it and it isn’t there.

Microsoft Research and Carnegie Mellon University, 2025

Researchers surveyed 319 knowledge workers who use AI tools at least once a week. Workers who had more confidence in the AI reported doing less critical thinking on the tasks they used it for. Workers who had more confidence in their own skills reported doing more critical thinking, such as checking and improving the AI’s answers.

SBS Swiss Business School, 2025

A researcher surveyed hundreds of people in the UK about how often they use AI tools and how they evaluate information. People who used AI tools more often scored lower in critical thinking and higher in cognitive offloading (relying on tools to assist with critical thinking). The pattern was strongest among participants aged 17 to 25, who used AI the most.

Brain and AI Research Group, Delhi, 2026

In an experiment, 120 young adults identified logical fallacies, some using ChatGPT and some on their own. The ChatGPT group got more answers right and reported far less mental effort. In interviews, the people who worked on their own described doing more independent reasoning and checking their own work.
