No this study is actually garbage. What it considers screen time is way too broad to be useful.

People aren't worried about screens in general, but social media in particular as well as other smartphone applications that are engineered to keep you engaged.

See Johnathan Haidt's literature review here for what an actually critical reading of the literature would lead you to reasonably conclude: https://jonathanhaidt.substack.com/p/social-media-mental-ill...

I don't disagree with you a bit! Science should be doubted in the correct ways, and for appropriate reasons, that's one of the main things I come to HN comments for. My issue with the OP was with his reasons - anecdotes about your children and personal opinions about the world might _trigger_ doubts, but they aren't good reasons to base those doubts on.

I've certainly been guilty of similar acts of pedantry so you'll hear no criticism from me on that front!
