The Social Media Addiction Debate

Addicted by Design: What the Social Media Lawsuits Are Forcing Us to Ask

The courts are answering a question psychology still won't — and the gap between them is where the truth lives.

Something unusual is happening in American courtrooms. A question the field has spent fifteen years failing to settle — is social media addictive, in the real, clinical sense of the word? — is now being answered by juries instead of clinicians. And the juries are saying yes.

In March 2026, a Los Angeles jury found Meta and Google liable for the harm their platforms caused a young woman who said she had been hooked since childhood, awarding $6 million and pointing not at the content she saw but at the way the products themselves were built. A day earlier, a New Mexico jury had ordered Meta to pay $375 million for misleading the public about how safe its platforms were for children. This August, a federal appeals court cleared the way for more than 3,000 similar cases — brought by families, school districts, cities, and states — to move forward, and a coalition of 29 state attorneys general took Meta to trial.

For a clinician, this is a strange and clarifying moment. The law is now treating as established fact something the diagnostic manuals still won't name. That gap is worth sitting with, because the truth lives in the tension between the two.

The word that isn't in the book

Here is what surprises people: “social media addiction” is not a diagnosis. It doesn't appear in the DSM-5, the manual American clinicians use, and it isn't in the ICD-11 either. Gambling disorder made the cut. Gaming disorder squeezed into the ICD. Social media remains conspicuously absent from both.

Part of that is an accident of timing. The DSM-5 was published in 2013 — the same year half of Americans finally owned a smartphone, when Instagram was barely a year into Facebook's ownership and TikTok didn't yet exist. The manual is almost exactly as old as the problem it is being asked about. At the time, the field folded these concerns into a broader “internet addiction” category and decided it did not yet meet the bar.

And the bar matters. To formally call a behavior an addiction, the field generally has to show three things: that it causes real harm in people's lives, that it is tied to an underlying biological process, and — the one that gets forgotten — that the benefits of the label outweigh the harms, including stigma and the pathologizing of ordinary behavior. That last criterion is why many thoughtful clinicians hesitate. When roughly 95% of teenagers are on these apps, you cannot build a diagnosis that accidentally pathologizes an entire generation.

What the brain science actually says (and doesn't)

This is where I want to be careful, because the pop-science version of this story is both partly true and badly oversimplified.

The true part: your dopamine system — the ancient reward circuitry built to make you chase food, connection, and safety — really does respond to likes and notifications. The variable, unpredictable timing of those rewards is the same mechanism that makes a slot machine compelling; you pull the lever not because you will win but because you might. Neuroimaging studies of heavy users show heightened activity in reward regions when they anticipate the next scroll, and in some studies, thinner grey matter in the prefrontal areas that govern impulse control.

The oversimplified part: none of that proves addiction, and the “dopamine detox / your brain is being hijacked” framing outruns the evidence. Almost all of this research is correlational. We genuinely don't know whether heavy use thins those brain regions, or whether people whose brains are already wired that way are simply drawn to heavy use in the first place. Prevalence estimates swing wildly — anywhere from 5% to 25% — depending entirely on which questionnaire is used and how generously “problematic” is defined. There is no agreed-upon threshold, no standardized instrument, no line in the sand. A recent commentary from a researcher who has spent years scanning people's brains during social reward reviewed the whole body of evidence and concluded, honestly: not yet.

So both things are true at once. The mechanism is real. The diagnosis is not yet earned. Holding only one of those is how people end up either dismissing genuine suffering (“just put the phone down”) or catastrophizing ordinary life (“we're all addicts now”). Neither is accurate, and neither helps anyone.

The reframe that actually matters

Here is what I think the lawsuits get right, even ahead of the science.

For years, the conversation about screens has been aimed at the individual: your willpower, your discipline, your failure to “just log off.” That framing quietly assumes the playing field is neutral — that using an app is like using a toaster, and if it is ruining your life, that is on you.

The lawsuits reject that assumption entirely. They don't argue the content is harmful; that argument has always been blocked by Section 230, the 1996 law that shields platforms from responsibility for what users post. Instead they go after the design — infinite scroll, autoplay, algorithmically personalized feeds, “streaks” that punish you for taking a day off, notifications engineered to pull you back. The claim is that these features were deliberately built to maximize time-on-app, that the companies understood the cost to young users, and that they did it anyway. By focusing on how the product is engineered rather than what is on it, plaintiffs found a path around the immunity that protected tech for a generation. Legal observers keep reaching for the same comparison: the tobacco litigation of the 1990s.

I find this clarifying because it relocates the problem to where it actually lives. Whether or not “social media addiction” ever enters the DSM, it is simply true that these products are engineered by some of the most talented people alive, backed by enormous computing power, with the explicit goal of capturing as much of your attention as possible. That is not a fair fight, and it is especially not a fair fight for an eleven-year-old's developing prefrontal cortex. Locating the struggle in a person's character — rather than in the deliberate design of the environment they are struggling against — is not just unkind. It is inaccurate.

So what do we do with this?

You don't have to wait for a diagnosis to take your own experience seriously. The clinical question of whether something qualifies as an addiction is different from the practical question of whether it is costing you something. If your use is eating time you meant to spend elsewhere, if the first and last thing you touch each day is a screen, if stopping makes you anxious — those are real signals, and they deserve attention regardless of what any manual says.

But take the pressure off the willpower story. If you have tried to cut back and it hasn't worked, that is not evidence of a defective character. You are up against a system built by experts to defeat exactly the kind of self-control you are trying to exercise. The interventions that tend to help are less about heroic discipline and more about changing the environment: turning off notifications, pulling the apps off your home screen or off the phone entirely, putting friction between you and the reflexive reach. You are, in effect, trying to make the machine a little less good at its job.

And if you are a parent, the developing brain is the whole ballgame. The lawsuits exist because the harm concentrated in kids, whose capacity for impulse control is still years from finished. Delaying access, keeping the youngest off entirely, and modeling your own boundaries matter more than any lecture.

The courts will keep moving faster than the science. Verdicts will be appealed, definitions will be argued, and it may be years before the field formally decides what to call this. But we don't actually have to resolve the diagnostic debate to act wisely inside it. We can hold both truths: that the evidence for “addiction” as a clinical category is still incomplete, and that people are being harmed by products deliberately designed to be hard to put down. The honest position isn't to pick one. It is to stop pretending the person holding the phone is the only one in the room worth examining.
