Synopsis

After more than a decade of improving or stable mental health, adolescents worldwide experienced a dramatic collapse in psychological well-being beginning in the early 2010s. Rates of depression, anxiety, self-harm, and suicide more than doubled across many measures, affecting teenagers in multiple developed countries simultaneously. Social psychologist Jonathan Haidt investigates this alarming trend, which he terms "the great rewiring of childhood." Haidt argues that two parallel developments created this crisis: the decline of play-based childhood and the rise of phone-based childhood. Beginning in the 1980s, children increasingly lost access to unsupervised outdoor play due to overprotective parenting, depriving them of essential experiences needed to develop resilience and independence. Then, between 2010 and 2015, smartphones and social media platforms fundamentally changed how children spend their time and form relationships. The Anxious Generation explores over a dozen mechanisms by which this digital transformation has disrupted healthy development, including sleep deprivation, attention fragmentation, social comparison, and addiction. Haidt demonstrates how social media particularly harms girls while boys retreat into virtual worlds, and he proposes concrete solutions for parents, schools, tech companies, and governments to restore healthier childhood experiences.
