AI Convenience Comes at a Cost, MIT Study Finds

A new MIT-led study is raising questions about the long-term cognitive effects of relying on AI tools like ChatGPT. Over a four-month period, participants who frequently used large language models for writing tasks exhibited weaker brain connectivity and reduced memory recall compared to those who completed tasks unaided. While the findings are preliminary and not yet peer-reviewed, researchers suggest that overreliance on AI could lead to a “cognitive debt” — especially in younger users. Experts emphasize the importance of strengthening foundational thinking skills before integrating AI tools into daily tasks.
