The problem is that popular discourse about social media is almost entirely based on vibes, anecdotes, and subjectively compelling stories. There simply isn't strong evidence for the "moral panic" in this case, as I point out at length in a recent deep dive into this issue. (1/2)
My current rough sense of history is that the last "moral panic" about social media turned out to be accurate warnings. The bad things actually happened, as measured by eyeball and by instrument. Now we all live in the wreckage. Anyone want to dispute this?
