The Anxious Generation: what the evidence says.
Jonathan Haidt’s book argues that smartphones and social media rewired childhood and caused a wave of teenage anxiety and depression. It has become a reference point for phone-free school campaigns. Many researchers say the evidence is weaker than the book suggests. A parent can learn something from both sides.
In short. Haidt argues that a phone-based childhood replaced a play-based one, and proposes four norms: no smartphone before about 14, no social media before 16, phone-free schools, more independence and play. Critics, among them the psychologist Candice Odgers in Nature, say the data show no, small or mixed associations, mostly correlational. A 2023 US National Academies report found too little evidence that social media causes population-level changes in teen health. Some steps make sense whoever turns out to be right.
The argument
The Anxious Generation, published in 2024, argues that in just over a decade a tech-based childhood crowded out the free play, independence and human connection that children need, and exposed them to new harms. Its answer is four norms, meant to be adopted together by families and schools so that no child is the only one without a phone:
- No smartphones before high school, around age 14; a basic phone until then.
- No social media before 16.
- Phone-free schools, with phones stored away for the whole day.
- Far more independence, free play and responsibility in the real world.
The campaign around the book works for phone-free schools and for laws on how social media is designed.
The critique
- The associations are small or mixed. Reviewing the book in Nature, Candice Odgers wrote that its suggestion that digital technology is rewiring children’s brains and causing an epidemic of mental illness is not supported by science. Hundreds of researchers have looked for large effects and found a mix of no, small and mixed associations, mostly correlational.
- Direction and cause are unclear. The US National Academies concluded in December 2023 that there is not enough evidence to say social media causes changes in adolescent health at the population level, though it has the potential to both harm and benefit; much research cannot tell whether social media affects health or health affects how teens use it. It recommended a more judicious approach than broad bans.
- The average link is small. A large analysis of three datasets with 355,358 adolescents found the link between digital technology use and wellbeing to be negative but small: at most 0.4% of the differences in wellbeing.
Odgers also warns that blaming phones could distract from other causes of young people’s distress.
Where Europe stands
WHO Europe found problematic social media use among adolescents rising from 7% in 2018 to 11% in 2022, while heavy users without problematic signs reported stronger support from friends. Policy is moving anyway: most of Europe now limits phones at school, and the EU has proposed age rules and design rules for social media. Country by country: phones in schools and social media age limits.
What a parent can take from both
- Protect sleep. Screens late in the evening have measurable effects on sleep in lab studies: the phone before bed.
- Watch the pattern, not only the hours: losing control, distress without the phone, other things dropping away. The signs researchers use.
- Mind the design: endless feeds, autoplay, streaks. Infinite scroll.
- Give independence and outdoor time. It costs little, and time outdoors has modest benefits for attention in studies: nature and attention.
- Talk often. In a 2026 EU survey, three in four parents talked with their child about social media every week: the numbers.
Whether to delay a smartphone or social media is a family’s choice; the debate is about how large the harm is, and the research cannot yet settle it.
Where we stand
We make Lychnos Ring for adults who want less of the feed in their own day; it is not meant for children. It is in development.

Questions
Is The Anxious Generation right about phones and teens?
It is contested. Haidt argues that smartphones and social media caused a rise in teen anxiety and depression. Many researchers, and a 2023 report of the US National Academies, say the evidence does not show that social media causes population-level changes in teen health, though it can both harm and help.
What are the four norms in The Anxious Generation?
No smartphones before high school, around age 14; no social media before 16; phone-free schools; and far more independence and free play for children.
