Acclaimed psychologist Jonathan Haidt reveals how the decline of free-play in childhood and the rise of smartphone use among adolescents is changing our world From 2010, as teens traded in their flip phones for smartphones packed with social media apps, unsupervised time online soared while face-to-face conversations with friends and family plummeted, and so did mental health. This profound shift took place against a backdrop of diminishing childhood freedom and over-supervision in the real world, depriving children of the experiences they most need to become strong and self-governing adults. The Anxious Generation delves into the latest research to show how this shift from free-play to smartphones disrupts development – from sleep deprivation to addiction – and lays the foundations of isolation and fear that define society today. Grounded in ancient wisdom and packed full of cutting-edge science and practical advice, this eye-opening book is a life-raft for anyone who wants to understand how the most rapid rewiring of human relationships and consciousness in human history has made it harder for all of us to think, focus, forget ourselves enough to care about others and build close relationships.
