New study says: ChatGPT can damage your brain

Does ChatGPT hurt critical thinking skills? A new study by researchers at MIT's Media Lab has yielded some disturbing results.

The study divided 54 subjects — ages 18 to 39 from the Boston area — into three groups and asked them to write SAT essays using OpenAI’s ChatGPT, Google’s search engine, and nothing at all, respectively. The researchers used an EEG to record the writers’ brain activity in 32 regions and found that of the three groups, ChatGPT users had the lowest brain engagement and “persistently performed poorly across neural, linguistic, and behavioral levels.” Over several months, ChatGPT users became lazier with each subsequent essay, often resorting to copy-and-paste by the end of the study.

The article suggests that its use may actually harm learning, especially for younger users.

The paper's lead author, Nataliya Kosmyna, felt it was important to publish the findings to raise concerns that, as society increasingly relies on ChatGPT for immediate convenience, long-term brain development may be sacrificed in the process.

"What really motivated me to publish it now before waiting for a full peer review is that I'm afraid that in 6-8 months, there will be some policymaker who will decide, 'let's do the GPT kindergarten.' I think that would be absolutely bad and harmful," she says. "The developing brain is at the highest risk."
