Jonathan Haidt did not expect to become the face of a global movement against social media. As Haidt's influence has grown, so, too, have objections from critics. At issue is his central claim that smartphones and social media are causing a mental health epidemic in young people. In research released this week, Haidt and his co-author, Zachary Rausch, claim to demonstrate causal links between social media platforms and the harms they say they are doing to children. Not just harms like anxiety and depression, but also frequent sexual harassment and cyberbullying. "The biggest, clearest one, I think, is sextortion," [said Haidt]. "That's the one that just stands out like a sore thumb. Kids, if they're on social media, they can get sextorted. If they're not, they can't, really. And the kids who get sextorted are deeply shamed. They shared a picture of themselves " teenage boys usually " and then their lives are ruined, and some of them commit suicide. So I'm just saying that there are so many different mechanisms by which kids are getting harmed. Depression and anxiety are just two of the pathways. What parents want to know and what legislators want to know is: Is this consumer product, which all kids are consuming massive quantities of, is this consumer product hurting kids? And guess what? We have seven different lines of evidence saying, "Yes, it's hurting kids." And Meta " I mean, my God, the data they have on harm is astonishing."
