- Tension: We treat doomscrolling as a dopamine addiction or a moral failure, yet every tool designed to stop it — screen time limits, app blockers, willpower — fails within days.
- Noise: The addiction framework makes scrolling a weakness to overcome, while the design-blame framework makes you helpless prey. Both miss the psychological function the behavior actually serves.
- Direct Message: Doomscrolling is your nervous system’s attempt to metabolize uncertainty in a safe dose. The people who stop aren’t the ones who kill the impulse — they’re the ones who find a better place to feed it.

Elena, a 38-year-old UX designer in Portland, set a timer on her phone last Tuesday. She wanted to know exactly how long she’d spend scrolling before bed. The answer was two hours and fourteen minutes. She wasn’t looking for anything specific. She wasn’t even particularly interested in what she was reading. A celebrity breakup. A K-pop controversy she had zero context for. A thread about microplastics in tap water. A video of a dog reuniting with its owner after surgery. When the timer went off, she told me she felt something close to nausea, but also something else she couldn’t name. “It wasn’t that I was entertained,” she said. “It was more like I was conducting an experiment I couldn’t stop running.”
That word, experiment, is the one that stuck with me. Because behavioral scientist Dr. Jud Brewer, who has studied habit loops for over two decades and whose work on curiosity and craving has reshaped how we think about compulsive behavior, recently offered a framework that makes Elena’s word choice feel less metaphorical and more diagnostic. The real engine of doomscrolling, he argues, isn’t boredom. It isn’t dopamine addiction in the way most pop psychology describes it. It’s an unmet need for what he calls “controllable uncertainty,” the kind of low-stakes unpredictability our brains are wired to seek when the high-stakes unpredictability of real life becomes unbearable.
I think he’s right. And I think this reframing changes everything about how we should respond to our own screen habits.
The dominant narrative about doomscrolling leans on addiction metaphors: dopamine hits, variable reward schedules, the slot-machine comparison that’s been recycled so many times it barely registers anymore. These aren’t wrong, exactly. They’re just incomplete in a way that keeps us stuck. If the problem is purely neurochemical, purely about hijacked reward circuits, then the solution is willpower, screen time limits, app blockers. And yet research published in the Journal of Behavioral Addictions in 2023 found that most people who set screen time limits override them within the first week. The limits don’t hold because they’re treating a symptom while ignoring the function the behavior serves.
Marcus, a 45-year-old middle school principal in Atlanta, described his scrolling pattern in a way that maps perfectly onto Brewer’s framework. “My job is nothing but uncertainty I can’t control,” he said. “Will this kid’s parents call back? Will the district cut our funding? Will there be another incident in the hallway?” By the time he gets home, he’s spent nine hours navigating situations where outcomes are unpredictable and the stakes feel enormous. His phone offers a different proposition entirely: outcomes that are unpredictable but meaningless. The next post might be funny. It might be tragic. It might be infuriating. But none of it requires a decision. None of it carries consequences.
This is what controllable uncertainty looks like in practice. You’re not scrolling because you’re bored. You’re scrolling because your nervous system is craving the sensation of not knowing what comes next in a context where not knowing can’t hurt you. It’s uncertainty with a safety net. The infinite feed provides a stream of micro-surprises that satisfy the brain’s novelty-seeking circuitry without any of the threat signals that accompany real-world unpredictability.
Dr. Ethan Kross, a psychologist at the University of Michigan whose research on internal dialogue and emotional regulation has been widely cited, frames it slightly differently but arrives at a compatible conclusion. His work suggests that when people feel their “chatter” (his term for the spiral of anxious inner monologue) is unmanageable, they reach for activities that provide a sense of agency over their attentional field. Scrolling feels like choosing, even when the algorithm is doing most of the work. You can stop anytime. You can swipe past anything. That illusion of control over an uncertain stream is psychologically intoxicating when every other uncertain stream in your life feels like it’s controlling you.
We explored a version of this in a recent piece on how the most-informed generation of parents has the least confidence, where I argued that the problem isn’t too much information, it’s information without hierarchy, without a signal telling you which data points actually matter. Doomscrolling operates on the same principle. The feed gives you everything at once, Korean celebrity gossip next to climate data next to a recipe next to breaking news, and your brain processes the flattened hierarchy as a kind of relief. When everything is equally (un)important, nothing demands the weight of a real response.
Nadia, a 29-year-old doctoral student in Chicago, told me she notices the pattern most acutely during her dissertation writing weeks. “The more uncertain I am about my argument, the more I scroll,” she said. “And the weird part is, I’m not procrastinating in the usual sense. I’m still thinking. It’s like my brain needs to chew on randomness for a while before it can tolerate the specific, high-stakes uncertainty of whether my chapter is any good.” She paused. “I just never thought of it as meeting a need before. I always thought of it as failing.”
That distinction, between a moral failure and a functional behavior, is where the conversation about doomscrolling keeps getting derailed. The addiction framework turns scrolling into something you’re doing wrong, a weakness to overcome. The controllable-uncertainty framework turns it into something your psyche is doing for you, clumsily, with real costs, but with a logic you can actually work with once you see it.
Consider what this means for the advice we give. “Just put the phone down” makes as much sense as telling someone with chronic pain to “just stop hurting.” If doomscrolling is serving a regulatory function, if it’s your nervous system’s attempt to metabolize uncertainty in a manageable dose, then removing the behavior without addressing the underlying need just creates a vacuum. That vacuum gets filled by other compulsive behaviors. Snacking. Shopping. Picking fights about nothing. As We wrote about couples who last being the ones who can sit with boredom together, there’s a profound difference between eliminating discomfort and learning to tolerate it. The same principle applies here.
There are counterarguments worth taking seriously. Some researchers, including scholars at Stanford’s Persuasive Technology Lab, maintain that design features (autoplay, infinite scroll, notification patterns) bear primary responsibility for compulsive use. And they’re right that the architecture matters enormously. A slot machine’s pull frequency is designed to exploit variable reward schedules, and social media feeds are engineered with the same precision. But blaming design alone creates a kind of learned helplessness. If the app is the predator and you’re the prey, the only option is avoidance. The controllable-uncertainty framework offers something more useful: understanding. You’re not prey. You’re a person with a legitimate psychological need that’s being met by the cheapest available option.
The more interesting question is what happens when you start meeting that need deliberately, with higher-quality sources of controllable uncertainty. Brewer’s own research points toward curiosity as the bridge. When you notice the urge to scroll, he suggests getting genuinely curious about the urge itself. What does it feel like in your body? What were you thinking about right before? This isn’t mindfulness as a platitude. It’s redirecting the uncertainty-seeking mechanism toward internal experience, which is endlessly unpredictable and completely safe.
Other researchers have pointed toward activities that provide structured novelty: walking an unfamiliar route, cooking without a recipe, reading fiction (where the uncertainty of narrative provides the same micro-surprises without the algorithmic manipulation). A 2022 study in Computers in Human Behavior found that participants who replaced 30 minutes of daily scrolling with 30 minutes of reading fiction reported lower anxiety and comparable satisfaction of what the researchers called “novelty needs.” The unpredictability was still there. The safety was still there. But the cost to attention, mood, and sleep was dramatically lower.
As DM News reported in a piece on super agers who produce new brain cells into their 80s, the habits that protect cognitive function over a lifetime are surprisingly ordinary: consistent social engagement, learning new skills, maintaining curiosity. What these habits share is exactly what Brewer is describing. They provide controllable uncertainty. They keep the brain’s novelty circuitry active without flooding it. And they do it in a way that actually builds capacity over time rather than depleting it.
David, a 52-year-old electrician in Tucson, put it to me plainly: “I started playing chess online instead of scrolling the news. I’m terrible at it. But I noticed I sleep better. My wife noticed I’m less irritable.” He laughed. “I’m losing at chess and winning at everything else.” What David stumbled into, without knowing the terminology, was a substitution that preserved the psychological function (controllable uncertainty, low-stakes unpredictability, a stream of outcomes he couldn’t predict) while removing the elements that were quietly degrading his well-being: the emotional manipulation, the outrage cycles, the anxiety spirals about health threats he couldn’t do anything about at 11 p.m.
Elena, the UX designer who started this whole conversation with her two-hour timer, sent me a follow-up message a few weeks later. She’d started keeping a sketchbook on her nightstand. Nothing disciplined, nothing goal-oriented, just drawing whatever came to mind before sleep. “It scratches the same itch,” she wrote. “I don’t know what I’m going to draw until I draw it. There’s a tiny surprise every time. But when I close the book, I feel like I made something instead of just consuming something.”
That last sentence is where I keep landing. The need for controllable uncertainty is real. It’s not a character flaw, and it’s not going away. Our brains evolved to scan for novelty because, for most of human history, the creature that noticed the unexpected thing in the grass was the one that survived. That scanning impulse doesn’t care that the grass is now a 6.7-inch screen. It just wants to find something. The question isn’t whether to honor that impulse. It’s whether what you’re feeding it is nourishing anything at all, or just keeping you full enough to forget that you’re still hungry. The people who stop doomscrolling don’t become people who stop seeking uncertainty. They become people who found a better place to look for it.
