Jonathan Haidt, welcome back to Hard Fork.

Thank you, guys.

Great to be back.

So when my book came out, I thought that the main problem was mental health.

And there's a big debate in the academic world.

Well, OK, people who use social media more are more depressed.

But is that correlation or is it causation?

And that has kind of defined the scope of the debate.

And that's gone on for a couple of years now.

And it's what Mark Zuckerberg says to defend himself.

Oh, there's no evidence of causation.

Well, guess what?

There are tons and tons of evidence of causation.

And Metta did some of the best studies to show it.

There's so many different kinds of evidence, including what the kids themselves say, what the parents say, what the teachers say.

Everybody sees it.

That's evidence.

And then there are experiments with random assignment that show that when you get off social media for at least a week, depression gets less.

So I was collecting all that evidence for this big review paper.

That's one of the two projects.
