On Social Media Addiction
Last week, a Los Angeles jury ruled that Meta and YouTube intentionally addicted a young woman from the age of six, causing lasting damage to her mental health and awarding her $6 million in damages. Meta's response was to call teen mental health "profoundly complex", which is technically true, and also one of the most cynical deflections I've heard from a corporation that had internal research showing exactly what their platforms were doing to children, and chose growth targets over it anyway.
I want to take a step back from the news for a moment, because I think the science underneath this story is just as (or more) important than the verdict.
Most of us think of dopamine as the reward chemical - and it does play a role in pleasure - but its most powerful function is in anticipation and uncertainty. It ‘fires’ strongest not when the reward arrives, but in that suspended moment of not knowing whether it will. That unpredictability is the engine of compulsive behaviour, and it's exactly what these platforms were built around. The platform's architecture is deliberately built for our neural architecture and it has been refined over years with the help of behavioural scientists whose job was not to make the product safer, but to make it stickier.
What makes this particularly troubling is the developmental context in which all of this is happening. The prefrontal cortex - the region of the brain responsible for impulse control, emotional regulation, and the ability to weigh long-term consequences - continues maturing well into the mid-twenties. In plain terms, the part of the brain that would help a young person put the phone down is the same part that is still being built.
So when we talk about teenagers lacking self-control (as has been argued), we are expecting the one group of people who are both neurologically primed to care most about social belonging and least equipped to regulate that drive - adolescents, navigating their first steps into independent social identity outside the family - to exercise restraint against some of the most sophisticated behaviour-modification technology ever built, deployed by companies with effectively unlimited resources and, until very recently, almost no regulatory constraint whatsoever.
For Those of Us Raising Kids
And it’s all too easy to locate the problem in the child. We talk about screen time limits and digital literacy and teaching kids to self-regulate, all of which has merit, but it puts the burden of resistance on the person least equipped to carry it, and it misses something much more fundamental about what adolescence actually is.
Erik Erikson was a German-American developmental psychologist whose work in the mid-twentieth century gave us one of the most enduring and clinically useful maps of the human lifespan. He identified the central task of adolescence as identity versus role confusion, the process of answering, for the first time and in earnest, the question of who you are and who you wish to be. And that process has always been messy by design. It happens through risk-taking and rebellion, through sexual awakening and peer belonging, through trying on different versions of yourself and testing your values against a world beyond your family.
I think about my own teenage years sometimes, and honestly, I feel lucky. The embarrassing experiments, the bad decisions, the identity-searching, all of it happened in a relatively small, forgiving world and my mistakes weren't permanent and my ‘audience’ was limited. I got to figure out who I was with some privacy, some space, and a reasonable chance of recovering from getting it wrong.
Social media has changed so much of how teens navigate their world now. Identity is no longer explored, it is performed, publicly and permanently, to an unlimited audience, before the self is anywhere near formed. Risk and rebellion, once contained within peer groups and recoverable from, now play out on platforms with infinite memory and reach.
Erikson understood that healthy identity formation depends on fidelity, the presence of people the young person can trust to hold them steadily while they figure themselves out. You are that, and the research is consistent, in that the quality of the parent-child relationship is the strongest protective factor against social media harm, not because it removes the exposure, but because it gives them somewhere to return to and to feel safe, seen, soothed and secure (the key ingredients of relational security).
So What Do We Actually Do?
I want to resist the urge to end this with a tidy list of tips, because I think that can sometimes let the bigger picture off the hook. So let me say first, that this requires structural change, regulation, and corporate accountability, and last week's verdict is a meaningful step toward that even if it takes years to translate into anything more substantial.
In the meantime, let me offer this. Stop framing your relationship with your phone as a discipline or willpower problem. Instead, notice the moments you reach for it and get genuinely curious about what need you're trying to meet - boredom, loneliness, anxiety, avoidance - because the simple act of naming that need creates a pause, and that pause is far more powerful for response inhibition and meaningful behaviour change than trying to resist it blindly.
From there, shape your environment in a way that creates just enough friction so that reaching for your phone (or opening specific apps) becomes a conscious choice rather than an automatic reflex, because your environment will always outlast your willpower, especially when you’re up against a system that has been carefully engineered to capture and keep your attention.
And if you have teenagers, understand that the most protective thing you can give them isn't a screen time limit, it's a relationship with you that feels more rewarding than the alternative.
As always, hit reply. I'd genuinely love to know what you think.
