Unlocked: The Real Science of Screen Time (and how to spend it better) by Pete Etchells- Book Review

For the past decade, a dominant cultural narrative has insisted that we are living through a digital "addiction" crisis. From headlines to dinner table debates, we’ve been told that smartphones and video games are the primary culprits behind a precipitous decline in mental health and the erosion of our communal bonds.

However, author Pete Etchells invites us to look closer at this panic. He points out a glaring irony: while screens were relentlessly demonized for years, they were suddenly championed as essential lifelines during the COVID-19 pandemic. Yet, as soon as the lockdowns lifted, the narrative reverted to its original, fearful status quo.

In his work, Etchells seeks to dismantle these rigid assumptions. He doesn't just offer an opinion; he provides a rigorous interrogation of the science, the history, and the ethics behind our digital lives.

In chapter 1, Of Panics and Pandemics, Etchells argues that the received wisdom regarding blue light, mental health crises, and screen addiction is built upon shaky data. While high-profile figures have relied on specific data sets, Etchells points out that other research into the same questions is far less conclusive. He warns against changing government policies based on vibes and anecdotal data rather than rigorous scientific inquiry. He also touches on the dietary detox lens through which screen use is often viewed, an area frequently governed by unscientific trends. Because screen time is rarely defined clearly, playing a cooperative game while socializing via headset is often lumped in with solo doomscrolling. This lack of rigor, combined with the fact that people are bad at self-reporting their own use, leads to deeply flawed data sets.

Chapter 2, Are Smartphones Destroying a Generation? examines the fallout of influential articles that linked poor mental health to smartphones. Etchells argues that the correlation between screen time and suicide risk factors was presented with a neatness that ignores scientific complexity. In reality, the statistical link between social media use and depression is often incredibly weak. He introduces the concept of p-hacking, where researchers manipulate large data sets until they find a significant result, and the bullshit symmetry principle, which states that refuting misinformation takes significantly more energy than creating it. He concludes that we must ask if smartphones are a genuine crisis or simply the latest in a long line of moral panics, following in the footsteps of books, comic, Elvis Presley’s hips, rock and roll, Dungeons and Dragons, videogames etc

In chapter 3, The Mirror in Your Pocket, Etchells suggests the online world doesn't necessarily cause mental health issues but rather amplifies and mirrors existing real-world problems. For example, 90% of those bullied online were already being bullied in person. He says we might need to look beyond the raw data and look at context.

Chapter 4, The Light in the Darkness, deconstructs the blue light myth. Etchells explains that while teenagers are losing sleep, it is often due to natural shifts in circadian rhythms combined with early school start times. The actual sleep loss attributed specifically to technology is roughly 3 to 8 minutes per night, hardly the apocalyptic figure reported by the media. He suggests the real source of teen anxiety may be the state of the world itself rather than the device used to read about it.

In chapter 5, Attention, he refutes the myth that humans now have a shorter attention span than a goldfish. He distinguishes between attention and focus, noting that while we are poor at multitasking, national productivity has actually increased in the digital age. 

Chapter 6, Ghouls in the Machine, looks at the ethics of algorithms. While not inherently evil, these systems are built by humans with biases. He is particularly critical of the gaming industry’s use of loot boxes and monetization, noting a clear correlation with problem gambling in an area where the industry remains lucratively self-regulated.

The most provocative stance comes in chapter 7, Digital Addiction. Etchells states that digital addiction does not exist in the way we think it does. He argues that using substance abuse questionnaires for video games is scientifically unsound because it ignores the lack of chemical ingestion. Instead, we should view these behaviors as habits or distractions. 

In the final sections, Etchells offers practical suggestions: refer to technology habits rather than addiction, identify patterns through self-reflection, delete stressful apps, model supportive behavior with children, and remain skeptical of media reports that demonize technology. Ultimately, technology is a tool that reflects the best and worst of us, offering amazing opportunities for connection and the search for truth.

Overall, I enjoyed my time with the book as it is scientifically based and also raises a lot of the same issues I raised about Haidt’s work. I wrote in the review of that book:

I do think Haidt misses it (the point) that he doesn’t look at how many young people feel disillusioned by a capitalist system that seems to prioritize profit over people and planet. They are concerned about issues like climate change, social injustice, and economic inequality, and are seeking alternatives that prioritize sustainability, fairness, and community well-being. They are suffering from Empathy Fatigue but they cannot look away as there is a constant stream of bad news so they are finding their tribes online which makes them more brittle in their opinions and less able to listen to the other side. To be honest, this is a whole world issue with the rise of populism but I do think Haidt misses out on the bigger existential social malaise affecting most of the world with the rise of social media.

Etchells discusses this and I think that is only right but I worry that governments around the world are all bought in on the Haidt Hype Train. We’ll see how things play out after the Australia Social Media ban for under-16s and then we can investigate with proper data. Until then, I’m all in with Etchells!
