If ChatGPT generated the text, participants weren't encoding it into memory through the cognitive processes normally involved in writing; they were essentially passive recipients of AI output. Isn't it a trivial finding then, that participants could barely recall a text they didn't write? Also, the study is small (54 participants), not peer-reviewed, and conflates two different issues: the cognitive effort during task completion versus memory retention afterwards.

Doesn't the decline of IQ rather correlate with smartphone ubiquity, particularly after 2010, and the steepest declines appear in 18-22 year-olds—the heaviest smartphone users? Multiple studies link smartphone addiction specifically to reduced cognitive abilities, not technology broadly.
