Intelligence Squared

This is the second instalment of a three-part conversation. Bestselling author and social psychologist Jonathan Haidt has dedicated his career to speaking truth and wisdom in some of the most challenging spaces – communities polarised by politics and religion and university campuses mired in culture wars. Now he turns his attention to what he sees as a perfect storm of factors that are causing a collapse in mental health among teenagers today. According to the American College Health Association, since 2010 anxiety among American college students has increased by 134%, depression by 106%, bipolar disorder by 57%, and anorexia by 100%. Haidt recently came to the Intelligence Squared stage where in conversation with BBC presenter Sarah Montague he drew on his new book The Anxious Generation, which has shot to No 1 in the Sunday Times bestsellers. He argues that the decline of free play in childhood and the rise of smartphone use among adolescents are the twin sources of increased mental distress among teenagers
