I agree that Haidt is a poor champion for the cause.
He’s popular because we are seeing something real happening to our kids and Haidt is the only person who is trying to describe whatever’s going on. We agree with the conclusions because we see it in our own kids, not because of the “moral panic”. It’s a shame he gets there in such a sloppy way, but he’s describing a real phenomenon.
I, as a parent, do not need articles and longitudinal studies and double blind peer reviewed studies to tell me that the thing I can observe with my own eyes is real.
