The controversial social psychologist Jonathan Haidt has a new book coming out entitled The Anxious Generation: How the Great Rewiring of Childhood Is Causing an Epidemic of Mental Illness. Haidt excerpts the book in his article, “End the Phone-Based Childhood Now,” in The Atlantic. In it, Haidt steps back and describes the enormous transformation that has occurred in the experience of childhood and links it to dramatic negative shifts in mental health, social connection and academic achievement, along with declines in dating, sexual activity, and teenage employment.
