The Anxious Generation: How the Great Rewiring of Childhood Is Causing an Epidemic of Mental Illness is a 2024 book by the social psychologist Jonathan Haidt. It argues that a ‘great rewiring’ of childhood — the swap of a play-based childhood for a phone-based one, concentrated in the years 2010 to 2015 — caused a sharp, measurable rise in adolescent anxiety, depression, self-harm, and suicide, with the sharpest effect on girls. Haidt’s case rests on a discontinuity around 2012, when smartphone ownership, front-facing cameras, and the like/retweet button spread together, displacing the unsupervised play, sleep, and face-to-face contact that adolescent development requires. The book’s remedy is four collective norms rather than individual willpower or government prohibition: no smartphones before high school, no social media before 16, phone-free schools, and far more independent, unsupervised play. It became a touchstone of the debate over smartphones, social media, and youth mental health, and a spur to school phone bans and age-verification legislation.

  • Jonathan Haidt on Adjusting to Smartphones and Social Media — the book’s hardback release occasions Haidt’s second Conversations with Tyler appearance, an adversarial exchange with Tyler Cowen. Haidt lays out the 2012 discontinuity, reframes the smartphone as an ‘experience blocker’ rather than a pure time-cost, cites Leonardo Bursztyn’s finding that teenagers are trapped in a collective-action problem over platform use, and sets out the book’s four-norm remedy alongside narrower policy asks (raising the COPPA data-consent age to 16, narrowing Section 230 for addictive design choices). Cowen presses the book’s near-silence on social media’s benefits and its causal claims against historical mood-shifts and the COVID school-closure natural experiment; the two converge on genuine common ground that the cost-benefit ratio is negative for 11–14-year-old girls on Instagram and TikTok.
