There is no evidence that AI causes brain damage. (Not yet anyway.)

Unpacking the viral, un-peer-reviewed study on LLM use and brain function.

Reading bad science journalism is bad for your brain, too.

There’s a new (unreviewed draft of a) scientific article out, examining the relationship between Large Language Model (LLM) use and brain functionality, which many reporters are incorrectly claiming shows proof that ChatGPT is damaging people’s brains.

As an educator and writer, I am concerned by the growing popularity of so-called AI writing programs like ChatGPT, Claude, and Google Gemini, which when used injudiciously can take all of the struggle and reward out of writing, and lead to carefully written work becoming undervalued. But as a psychologist and lifelong skeptic, I am forever dismayed by sloppy, sensationalistic reporting on neuroscience, and how eager the public is to believe any claim that sounds scary or comes paired with a grainy image of a brain scan.
