MIT Study Finds AI Use Reduces Brain Activity, Weakens Recall
The research provides the first empirical evidence that reliance on tools like ChatGPT can diminish long-term learning skills.
AI and Cognitive Load
A study from the Massachusetts Institute of Technology (MIT), reported on Oct. 1, 2025, found that using large language models like ChatGPT for writing tasks measurably reduces brain activity and can impair long-term recall. The research provides some of the first empirical evidence of the potential negative cognitive effects of over-reliance on artificial intelligence.
Researchers used electroencephalography (EEG) to monitor the cognitive load of participants writing essays under three conditions: - Without any technology ("brain-only"). - Using Google Search. - Using ChatGPT.
The results showed that participants using ChatGPT had the least neural activity, indicating …
