Jonathan Haidt is the one who wrote The Righteous Mind which has been discussed here. That book has an interesting viewpoint that I find useful to remember in some Thanksgiving conversations, but Haidt doesn't do much useful with it in the book.

In his about page:

But the transformation of society in the 2010s was not caused by anxious college students. They were simply the “canaries in the coal mine” — the first generation to have moved their social lives onto social media platforms. As soon as they did so, around 2012, an epidemic of mental illness began.

There's a number of places that statement could lead, but he skips over the "transformation of society" part as far as I can tell. His policy proposals are to change the "Must be 13+ to register" checkbox to 16 and he wants Congress to make Facebook give him access to data for research.

I think he's found a real issue. I don't think he has a useful idea of what to do about it though.

Also from his about page:

We showed how this anxious new generation arrived on campus and demanded new norms, procedures, and bureaucratic responses that are incompatible with the older truth-seeking culture of universities.

University are so much rosier when we forget about the arms race of tuition and student loans and credentialism.
