I'm very concerned about the relationship between smartphone use and America's mental health crisis. But many researchers don't see things my way. They insist that there is little to no empirical data showing that smartphone and social media use drives up anxiety or depression. So what’s the truth about smartphones, social media, and mental health? That’s the question that the NYU researcher Jay Van Bavel set out to answer with his collaborator Valerio Capraro. They took dozens of claims about smartphones, sent them to hundreds of experts in the field, and asked them if these claims were probably true, probably false, or unknown—and why. The result was a massive survey, one of the largest of its kind in the history of psychology. Today, Van Bavel joins the show to tell us what he found, what surprised him, and why his consensus survey made so many researchers so angry.
