ChatGPT Use Linked to Cognitive Decline: MIT Research

A recent MIT Media Lab study raises concerns about the long-term cognitive effects of relying on ChatGPT. Researchers found that participants who regularly used the tool to write SAT-style essays showed the lowest brain engagement and underperformed linguistically and behaviorally compared to peers who used Google or no tools at all.

EEG scans revealed diminished neural activity in the ChatGPT group, which increasingly shifted from using the tool for support to copying content outright. The “brain-only” group showed the strongest cognitive function. These findings highlight the need for caution, particularly for younger users, as public health and education sectors grapple with AI’s growing role. Read the full article from The Hill here.
