AI Overload May Be Eroding Your Brain’s Power.

A new MIT Media Lab study (2025) found that using ChatGPT for essay tasks led to significantly weaker brain activity compared to writing without AI or using search engines, as shown by EEG scans. The ChatGPT group not only struggled to recall what they wrote, but also produced more formulaic text and felt less ownership over their work.

In a follow-up round, even after stopping AI use, previous ChatGPT users still showed reduced brain engagement—suggesting its effects might linger. What’s more, nearly 83% couldn’t accurately quote their own essay moments after writing—the kind of memory fade linked to long-term “cognitive debt”.

Avoid relying on Ai for thinking: use it as a tool not a crutch. Your brain’s agility depends on you.
