The Anxious Generation

Haidt argues that two trends collided between roughly 2010 and 2015: the decline of unsupervised, risky, real-world play, and the arrival of the front-facing-camera smartphone with always-on social media. The result, he contends, is a “great rewiring” of childhood that shows up in sharply rising adolescent anxiety, depression and self-harm across the Anglosphere, with girls hit hardest on the social-media channel and boys on withdrawal into screens. He ends with four prescriptions — no smartphones before high school, no social media before sixteen, phone-free schools, and far more unsupervised play. The causal claim is genuinely contested among psychologists, and the book has drawn substantial published criticism on the strength of the evidence; it is nonetheless the most-read statement of the case.

Why it’s on the list: Recommended independently by two very different curators, which is a signal in itself — and it is the reference text for a policy argument now being made in school districts and legislatures.

Where I saw it: Two separate lists. @NJBeisner’s September 20, 2025 video listing Charlie Kirk’s must-read books, and Michael Mauboussin’s favourite books of 2024, posted December 31, 2024.

Kyle’s note: “good but summarize as cellphones awful” — recorded verbatim from his transcription of the Beisner list. He confirmed on 2026-09-18 that he has not read the book, so the remark is the gist he has absorbed rather than a first-hand verdict, and the card stays in the anti-library.

Connections

• Jonathan Haidt — the author, whose earlier work on moral psychology and free speech runs into this.
• Social Media — the mechanism the book blames.
• Mental Health — the outcome it measures.
• Parenting — where its four prescriptions land.
• Michael Mauboussin — one of the two curators who recommended it.
