Book Review: Jonathan Haidt's Anxious Generation

If you’ve worked in schools over the last decade, you don’t need convincing that something has shifted. There is more anxiety, more dysregulation, and more conflict that seems to ignite faster and burn hotter.

In The Anxious Generation, social psychologist Jonathan Haidt argues that this isn’t simply “kids these days.” Instead, it reflects a significant environmental shift in childhood that accelerated between 2010 and 2012: a move from a play-based childhood to a phone-based one. Haidt describes this as a “great rewiring,” where constant connectivity, social comparison, and high-stimulation digital environments begin shaping development during the very years young people should be building independence, resilience, real-world competence and a sense of secure belonging.

What’s Changed?

Several key shifts from Haidt’s work are particularly relevant for schools and those supporting children and young people:

1. Childhood becomes smartphone-ledYoung people are now “always on,” navigating continuous social pressure, fragmented attention, disrupted sleep, and fewer genuine moments of rest.

2. Harms show up differently across groupsThe wider conversation around Haidt’s work often highlights patterns in how this shift presents. Social comparison and relational pressure are frequently discussed in relation to girls, while isolation, gaming and disengagement are more often discussed in relation to boys. These are not fixed rules, but they can help staff interpret behaviour with greater nuance.

3. A decline in free play and independenceWith less unsupervised play and fewer opportunities for risk-taking, children have fewer chances to practise negotiation, repair, frustration tolerance, and confidence-building.

4. Over-protection offline, under-protection onlineMany children experience tighter controls in the real world, while simultaneously being exposed to adult-level risks online — what Haidt describes as a modern safeguarding paradox.

None of this suggests that “phones are evil” or that parents are to blame. It highlights that the developmental environment has changed faster than our systems — and schools are experiencing the consequences.

What This Means in Schools

If pupils are arriving with less sleep, higher levels of stimulation, increased comparison pressure, and fewer experiences of real-world autonomy, then shifts in behaviour become predictable rather than puzzling. What can look like “defiance” often reflects a different underlying reality: lower tolerance for frustration and delay, faster threat reactivity when corrected, heightened sensitivity to shame, increased need for peer approval, and, for some, withdrawal or a growing sense of “what’s the point?” This doesn’t remove accountability. But it reframes the question from “Why are they like this?” to “What kind of environment helps them regulate, re-engage, and rebuild trust?”

The Role of Schools:

One of the central arguments in Haidt’s work is that solutions must be systemic. This cannot be left solely to individual families or teachers to navigate in isolation.

The public conversation around The Anxious Generation reflects this, with increasing emphasis on delaying smartphone access, limiting social media, creating phone-free school environments, and rebuilding opportunities for independence and play.

In England, updated government guidance (February 2026) supports schools to prohibit mobile phone use throughout the school day, including break and lunch times. In Wales, the Welsh Government has begun developing guidance to support schools in implementing clearer mobile phone policies. The direction is clear: stronger boundaries are being encouraged not as punishment, but as part of safeguarding and effective learning design.

Where This Aligns with Navigate’s Work:

Haidt’s framing reinforces something many educators already know: behaviour and mental health are shaped by environment, not just individual traits.

That’s why the most effective responses are preventative and cultural, rather than endlessly reactive. At Navigate, our work focuses on rebuilding the protective conditions that many pupils increasingly lack.

This starts with connection ensuring that every young person has access to trusted adults and experiences a genuine sense of belonging within the school community. When connection is consistent, pupils are more likely to feel secure enough to engage, take risks in their learning, and repair when things go wrong. Alongside this is regulation. Schools need predictable routines, opportunities for co-regulation, and clear processes for repair. Rather than expecting pupils to arrive fully self-regulated, we recognise regulation as something that is taught, modelled and supported through the environment.

We also prioritise safety, not just in a physical sense, but in how dignity is upheld day to day. This means creating systems where pupils can be corrected without shame, where discipline is consistent and understandable, and where emotional safety is not dependent on individual adults. Finally, there is independence. Many young people now have fewer opportunities to develop autonomy and real-world competence. Schools can play a vital role in rebuilding this - creating structured opportunities for pupils to take responsibility, solve problems, and experience success in meaningful ways. If the environment has changed, then the environment has to be part of the solution.
