Jonathan Haidt’s new book warns that the shift towards smartphone-centric childhoods is fuelling mental health issues among youth, prompting calls for policy changes and a reconsideration of modern childhood experiences.
For years, rising anxiety, depression, loneliness and self-harm among young people were often treated as an unfortunate fact of modern life. Jonathan Haidt’s “The Anxious Generation” argues that the problem is not inevitable at all, but the result of what he calls the “Great Rewiring of Childhood”: a rapid shift towards smartphone-centred lives, with children spending more time online just as they were becoming less independent offline.
At the heart of Haidt’s case is a simple claim: childhood has become less physical, less social and less risky in the real world, while becoming far more exposed to the pressures of always-on digital life. He says children need unstructured play, face-to-face conflict, wandering about without constant adult supervision and the chance to test themselves through manageable risk. In his view, those experiences build confidence and resilience, and their decline has left many young people less equipped to cope.
The book also argues that smartphones altered childhood at speed in the early 2010s, pushing many children towards what Haidt describes as a phone-based upbringing. According to reviews in The New York Times and the Wall Street Journal, he links that shift to a surge in adolescent mental-health problems and backs practical steps such as keeping smartphones out of schools and using feature phones instead. The idea has proved influential, helping to drive wider debate among parents, teachers and policymakers about what children should be allowed to carry, see and do online.
But the book has also drawn significant criticism. Candice L. Odgers, writing in Nature, argues that Haidt’s thesis risks confusing correlation with causation and says the evidence tying smartphones and social media directly to worsening mental health is weaker and more contested than he suggests. That disagreement matters because it shifts the discussion from a single villain to a more complicated picture, in which family life, schooling, social pressure and broader cultural change may all play a part.
Even so, the book’s appeal lies in the way it turns private worry into a public question. If children are struggling in large numbers, Haidt argues, families cannot solve the problem alone. He calls for coordinated action from schools, parents, governments and technology firms to create healthier norms around screen use, independence and childhood itself. Whether or not readers accept every part of his argument, the book has forced a reckoning with a question many adults can no longer avoid: what, exactly, does a healthy childhood look like in the smartphone age?
