The Economist Writes: Early evidence suggests phone bans at schools may do little to benefit pupils’ mental health

February 21, 2025

From Kenneth at Opal:

We’re excited to see research providing more nuanced insights into how smartphones and social media affect children's mental health. Like food, screen time isn’t inherently good or bad—it depends on the individual, context, and personal predispositions. That’s why outright smartphone bans in schools may not always be the best solution.

More importantly, we believe children and teenagers must develop a critical skill for the modern world: the ability to focus in a hyper-connected environment. Simply banning phones doesn’t teach them how to manage distractions—it removes the opportunity to build self-regulation.

At the same time, ongoing research is helping us better understand social media’s impact. For example, The Economist highlights a study by Amy Orben at the University of Cambridge that clearly links increased social media use to lower overall life satisfaction. Insights like these allow schools and policymakers to take more effective, evidence-based action.

That’s why we’re excited to pilot the Opal app with select schools (to be announced soon), helping students develop essential focus skills and regulate harmful screen time—while giving them the agency to take control of their digital habits.

Early evidence suggests such bans may do little to benefit pupils’ mental health

France has not allowed smartphone use in primary or secondary schools since 2018, claiming that it would help children focus, reduce their social-media use and mitigate online bullying. The Netherlands initiated a similar ban in January 2024. Hungary followed suit later that year. Legislators in Britain are considering similar measures. The key question facing them is whether banning smartphones in schools offers any benefits to mental health.

That there is a problem seems clear. In 2021 America's surgeon general compiled a report revealing that persistent feelings of hopelessness climbed by 40% among American high-school pupils between 2009 and 2019. The number who seriously considered killing themselves went up by 36%. What makes these findings all the worse is that 48% of mental-health problems (like depression and anxiety) that emerge during adolescence will plague people for the rest of their lives.

It is tempting to connect these trends with the increased availability of smartphones, but establishing a causal connection is difficult. Part of the problem is that smartphones contain multitudes. Using a smartphone to solve crosswords or read the news may well have markedly different psychological effects from intensive social-media use.

Children are no less varied. The brain undergoes profound changes during puberty, meaning that any research on the effects of smartphone use needs to consider the developmental age of the children being studied as well as their precise smartphone habits.

No studies have got this specific. Those that have come close, however, reveal that unfettered access to social media on smartphones during puberty, especially at critical moments when the brain is changing, may cause problems. One study, led by Amy Orben at the University of Cambridge, asked 17,409 people between the ages of ten and 21 how satisfied they were with their lives and how much they used social media.

The findings, reported in 2022 in Nature Communications, show that girls who increased their social media use over the course of a year were significantly less satisfied with their lives if the increase took place when they were between 11 and 13. Boys showed the same trend when increases took place when they were 14 or 15 years old.

How much of this will change by banning phones in schools is unclear. In a paper published in The Lancet in February, Victoria Goodyear at the University of Birmingham compared the mental well-being of students in schools that implemented restrictive smartphone policies with those with relaxed policies. She also monitored overall screentime. Her results show that, though those who spent more time on a smartphone overall did have a decline in mental well-being, there was no difference between the two groups. She and her colleagues argue that setting up policies at schools alone is simply not enough.

Researchers are trying to paint a complete picture with both hands tied behind their back. According to Dr Orben, social-media companies routinely refuse to give independent researchers access to detailed data on the behaviors of their users. This forces researchers to rely on less accurate proxy measures, like overall screentime. It also means that children playing educational games are being put in the same analytical bin as children who are on social media. A more nuanced picture of the effects of smartphones needs to be drawn.
