I mean, come on.
First claim in the article:
> But correlation is not causation, and research suggests that some of the supposed mental health crisis is an epidemic of overdiagnosis.
Linked paper doesn't support this. Only one study found evidence of overdiagnosis, and the data was both noisy and only focused on ADHD. It literally said "Most reviewed studies suggest that misdiagnosis does occur; however, only one study was able to examine overdiagnosis in child and adolescent mental disorders from a methodological point-of-view. This study found significant evidence of overdiagnosis of attention-deficit/hyperactivity disorder."
Another claim from the article:
> Meanwhile, youth have been doing better on many other outcomes: less crime, less smoking, less drug use, fewer teen pregnancies and fewer high school dropouts. If social media were truly “rewiring” the adolescent brain, we would expect the damage to be more consistent than a selective worsening on some measures and improvement on others.
This kind of muddled thinking is prevalent in the article. The vague term "rewiring" is being argued against, and the author expects that only one specific outcome should be consistent with it, and doesn't admit the obvious other explanation is that social media and internet addiction is replacing the other addictions.
I read the whole article and could deconstruct it more, but I won't--it's tinged with the author's own anecdotal conclusion that they turned out fine, so everyone else will.
