The Great Scroll: Why an Under-16s Social Media Ban is Just the Beginning
Last week’s news about the government proposing a blanket ban on social media for under-16s sent the internet into an absolute meltdown. Some people were crying "censorship!", but honestly, it got me thinking. We are living in an era where we are consuming vast quantities of absolute garbage, and we’re all a bit stuck in a dopamine pit. 🕳️
I decided to tackle the elephant in the room with my ICT group this week. We broke the ice by chatting about the new Toy Story 5 trailer—where the main villain isn't a malicious toy, but a highly addictive tablet. 📺 It perfectly set the stage for a deep dive into how algorithms are designed to keep us scrolling.
I expected teenage outrage about the ban. Instead, we had an incredibly mature discussion.
The Dopamine Pit and the Lost Art of Boredom
There are plenty of studies out there showing how short-form videos—those endless TikToks and Instagram Reels—are actively reducing our attention spans. You get a little mini-reward every thirty seconds, and it genuinely rewires your brain. We're seeing suggestions that this constant stimulation is impacting reading abilities in schools and the general capacity to just sit and concentrate.
Think about it: people can barely sit through a full-length film anymore. We've reached a point where television series have to start with a recap just to keep us engaged.
There was a brilliant bit of reporting on BBC News recently that perfectly captured this. They were recording in a school, talking to students about the proposed ban, and unsurprisingly, none of them were in favour. One young girl argued she needed her phone to keep in contact with friends. The reporter then gently pointed out her digital wellbeing app, which showed she’d been on her phone for nine hours over the weekend.
"What are you going to do with those nine hours instead?" the reporter asked.
Her response? *"Probably look at the wall."*
It’s a funny, incredibly teenage answer, but it highlights a massive issue. Algorithms have conditioned us to require immediate entertainment. By eliminating boredom, we've lost the quiet mental space where creativity, self-reflection, and emotional processing typically occur.
Confessions of a Scroller
Don't get me wrong, I am definitely consuming too much myself. I'll catch myself watching something on TV and suddenly I'm down an internet rabbit hole: *What's he been in? Who else plays for that team? That international player, what club does he play for?* Before I know it, I've lost an hour.
However, we have to separate the platform from the device. Smartphones are wonderful tools. They allow us to do our banking, our shopping, and navigate our communities. Personally, most of my screen time on a typical day is taken up by music apps and Waze. I would be much more in favour of banning the highly addictive social media platforms for kids, whilst still allowing them to have smartphones for those essential, independent living skills.
The Adolescent Brain Under Siege
While social media offers a sense of connection, its architecture is specifically designed to capture and hold attention. During the teenage years, the brain is uniquely sensitive to social feedback, peer acceptance, and reward. This makes young people incredibly vulnerable to algorithmic design.
Here is what that looks like in practice:
- The Comparison Trap: Social media presents a curated, filtered reality. Constant exposure to idealised bodies and lifestyles leads to upward social comparison. For young women especially, this is strongly correlated with body dysmorphia, anxiety, and the exhausting pressure of perfectionism.
- Sleep Disruption: The blue light from screens suppresses melatonin, delaying sleep. Beyond that, the "vampire routine" encouraged by infinite scrolling leads to chronic sleep deprivation, worsening mood and cognitive performance
- 24/7 Cyberbullying: Historically, bullying stopped when you got home. Now, harassment follows young people into their bedrooms. It’s inescapable, amplified by the ability to share humiliating content instantly, and often worsened by the anonymity of fake accounts.
- The Permanent Digital Footprint: Teenagers are biologically prone to impulsivity, but the internet is forever. A poorly judged comment or a private photo can be screenshotted and weaponised, impacting university admissions and future employment.
Key insight: The relationship between social media and mental health is often described as a "dose-response" effect. Moderate use (under an hour) has minimal impact, but the risks escalate sharply once you pass the three-hour mark.
The Silver Lining: Why Technology is Neutral
Because this technology exploits natural psychological vulnerabilities, simply telling a teenager to "put the phone down" rarely works without addressing the underlying design of the apps. Yet, it’s important to remember that the technology itself is neutral. The exact same infrastructure has birthed incredibly positive outcomes.
- Niche Community Building: Social media removes geographic barriers. Someone with a rare medical condition or a highly specific hobby can instantly connect with thousands of others globally for support and camaraderie.
- Democratisation of Voice: Anyone with a smartphone can now broadcast to the world, enabling citizen journalism and allowing marginalised groups to organise without needing traditional media gatekeepers.
- Economic Opportunity: The "creator economy" allows a local artisan or independent bookshop to compete. A small business doesn't need a billboard; they can spend a few pounds to target people who genuinely love their craft.
- Rapid Crisis Response: During natural disasters or missing person cases, these networks mobilise resources and coordinate relief efforts far faster than traditional broadcasts.
Behind the Curtain: The Attention Economy
To understand why our feeds look the way they do, we have to look at the mechanics. Think of cookies as the information gatherers and algorithms as the decision makers.
Cookies track your behaviour across the web. If you look at running shoes on a retail site, a third-party cookie notes it. When you open an app later, the algorithm uses that data, combined with your on-platform behaviour, to predict what will keep you engaged.
These algorithms aren't programmed to care about nuance, truth, or public wellbeing. They care about *engagement*. This drives emotional contagion—amplifying polarising, outrage-inducing content because it keeps people typing furiously in the comments. It isolates us in echo chambers, making our own opinions feel absolute.
Ultimately, social media is free because *we* are the product. The platforms gather our data, hold our attention, and sell highly targeted access to advertisers. Shaping public opinion is often just a byproduct of this massive monetisation machine.
Where Do We Go From Here?
Banning social media for under-16s might be a starting point, but it isn't a silver bullet. I genuinely think it's a good idea for everyone—regardless of age—to set strict digital wellbeing targets.
More than anything, we need better digital literacy. We need to educate people that consuming endless streams of short-form videos is harmful, but we also need to teach them how to harness the immense positives this technology offers. We have to learn to control the algorithm, rather than letting it control us.
