Edit: There’s a blog post on the failings of the study and the communication around it: Clickbait Neuroscience: Lessons from “Your Brain on ChatGPT” – Mind Brain Education
EEG revealed significant differences in brain connectivity: Brain-only participants exhibited the strongest, most distributed networks; Search Engine users showed moderate engagement; and LLM users displayed the weakest connectivity. Cognitive activity scaled down in relation to external tool use.
Over four months, LLM users consistently underperformed at neural, linguistic, and behavioral levels.
This lines up with my completely unscientific observation that the people who have started relying heavily on AI are dumbasses.
I’ve got some anecdotal evidence to suggest that people who go to the gym a lot also tend to be stronger. You know, there could be some connection between exercise and muscle growth… Someone should probably investigate that link, could be something there.
