A new study by scholars from MIT and Wellesley, titled “Your Brain on ChatGPT: Accumulation of Cognitive Debt when Using an AI Assistant for Essay Writing Task,” set up a months-long comparative experiment that measured the brains and essays of some student writers, and found that AI users “consistently underperformed at neural, linguistic, and behavioral levels.” Not only that, but the negative effects of using AI remained measurable in the participants afterwards, and even when they were doing their thinking without LLMs.
