“You stare at a screen. That’s all you do every night. No one wants to talk to you, and they get annoyed whenever you call.” Pete Etchells wrote those lonely words in a miserable teenage blog in 2002, just before 10pm on a bleak December night. He’s now a Professor of Psychology and the author of a new book on the science of screen time. To which you would be forgiven for responding: “Oh God — not another sermon on technology’s perils and the importance of a ‘digital detox’.”
After all, knocking technology seems to have been a collective New Year’s resolution for a certain sort of “psychologist”. Over the past month, global superstar Jonathan Haidt has been doing the rounds for his own new book, The Anxious Generation, warning how technology is “rewiring” children’s brains and “causing an epidemic of mental illness”. In a similar vein, author Abigail Shrier has been promoting her latest contribution, Bad Therapy, extolling the benefits of phoneless children. Certainly it’s a view that has found political currency on both sides of the Atlantic. Only last week, Florida’s Ron DeSantis signed one of the US’s most restrictive social media bans for children, while here in the UK the Government wants to ban phones in schools to improve educational standards.
It is into this fearful maelstrom that Etchells’s book enters, throwing down a rather unexpected conclusion into the mix.. Rather than spend page after page outlining how technology is corrupting Western children, he takes a more thoughtful view. Instead, he argues, “collectively, as a society, we have become too apprehensive — and even fearful — about screens”.
To justify this, Etchells explores the evidence for the harm caused by screens, and finds it unconvincing. Has screen time destroyed our attention span? Very unlikely. Does it interfere with adolescents getting enough sleep? Sometimes, depending on how and when the teenager is using the screen. Are smartphones destroying a generation’s mental health? It’s impossible to usefully answer such a sweeping question.
What studies have been done, he explains, are often small and poorly designed. They tend to rely on self-reporting, and elide correlation and causation. Some studies reported positive effects, or different effects for different groups. Building any kind of big picture is hindered by the fact that researchers are measuring different populations, different devices, different purposes, and different aspects of wellbeing or mental health.
Not enough evidence, then, but also no cause for immediate panic. Which raises the question: if no convincing evidence points to the harms of screen time per se, why are we so fearful of it? What does our unhealthy fixation on the power of technology say about us?
It’s true that young people, especially, are less happy, more anxious, and generally less able to cope with life than previous generations. A recent Resolution Foundation report found that a third of 18-24 year olds reported symptoms of poor mental health, and that one in 20 young people was prevented from working by ill-health. It’s also true that this rise in mental distress coincides with the spread of the internet, the smartphone and its seductive apps. But that doesn’t make for a simple, causal relationship.
Successive generations, let’s not forget, also have less independent time outside adult supervision, and fewer opportunities to take risks and initiatives for themselves. Kids first play outside when they’re a couple of years older than the age their parents did, and the kind of informal public spaces where their grandparents hung out together are turning into formal, privatised spaces for prescribed activities like shopping or organised sports. As Etchells points out, it’s fine to “talk about getting kids off their screens and ‘going outside’… but the reality is that, increasingly, there isn’t anywhere ‘outside’ for them to go”.
