An experiment from MIT’s prestigious Media Lab is raising fresh doubts about outsourcing schoolwork to ChatGPT. In the study, 54 adults wrote a series of structured essays while wearing EEG caps that tracked brain waves linked to focus, memory, and creativity.
One group wrote without any digital help, a second used Google Search, and a third relied on ChatGPT. The ChatGPT writers produced nearly identical, formulaic essays—two teachers called them “soulless” and lacking original thought—and they showed the weakest neural activity on every measure.
The findings suggest that while ChatGPT can be a helpful editing tool when used thoughtfully, relying on it too early in the writing process may dull critical thinking and hinder learning. As schools and universities increasingly integrate AI into classrooms, researchers urge caution and clearer boundaries.
