Is the current wave of concern about smartphones and social media just another moral panic, like the ones that arose in response to radio, television, and comic books? Or is the new "phone-based childhood" interfering with human development in an unprecedented way? In The Anxious Generation, Professor Jonathan Haidt focused on mental illness as the primary outcome of concern. In this lecture, he will argue that such a focus vastly understates the psychological and sociological harms resulting from the "great rewiring of childhood" into its current phone-based form. Professor Haidt will expand the story beyond mental health to present evidence of declines in education, attention, happiness, risk-taking, social capital, and the foundations of liberal democracy, all linked to changes in technology. He will argue that this far-ranging international destruction of human capital and human potential calls for immediate attention and action from scholars, legislators, and parents.
