You know the feeling. You pick up your phone to check one thing, and somehow 45 minutes vanish into a scroll-hole. It can feel like the screen has a tractor beam aimed straight at your thumb.

Turns out, that pull is real, measurable, and rooted in the same brain systems that drive other addictions. A 2026 study put it to the test, and the results explain a lot about why some people can't seem to put their devices down.

The joystick study

Researchers wanted to answer a simple question: when people with internet problems see online-related stuff (a gaming logo, a social media icon, a shopping app), do they automatically lean toward it, even without meaning to?

To find out, they had 1,015 people play a clever game with a joystick. When images popped up on screen, players either pushed the joystick away from them or pulled it toward them, and the researchers timed how fast they reacted.

The finding: across all groups, people tended to "approach" internet-related images. But the folks with the most serious internet problems showed the strongest pull. They were noticeably faster at yanking internet cues toward them than pushing them away. Their brains were basically saying "gimme" before they could think about it.

Two big ideas behind the pull

This isn't random. Scientists explain it with two main theories.

The "wanting vs. liking" split. This is the surprising one. As an activity becomes more addictive, the brain cranks up wanting it (the craving, the pull) without cranking up liking it (the actual enjoyment). So people end up wanting something more while enjoying it less. That gap, wanting more, liking less, is a hallmark of addiction. One study across many behaviors (gaming, social media, shopping, and more) confirmed it: as problems got worse, "wanting" went up while "liking" stayed flat. The fun fades, but the craving keeps growing. Rude.

The big-picture model (I-PACE). This framework says problematic internet use grows out of a tangle of factors: your personality and brain wiring, your emotional reactions to certain triggers, and how well you can control your impulses. Over time, triggers and weakened self-control team up to turn a habit into something that feels automatic, then compulsive. A 2025 update boiled it down to three forces: "feels better" (it soothes you), "must do" (it's automatic), and "can't stop" (self-control fails).

Triggers are everywhere

Here's the tricky part. The cues that spark cravings aren't just exciting things like a game itself. Studies found that people with internet problems reacted strongly even to neutral triggers, like a device showing a login screen.

For the most affected people, the reaction spread to all kinds of internet cues, not just their specific problem activity. In one striking study, problematic users' brains detected a Wi-Fi signal symbol faster than other people's brains did, before they were even consciously aware of it. Their minds were hunting for connection cues on autopilot. And feeling stressed or down made this automatic radar even more sensitive.

The unsettling takeaway: in a world packed with screens, phones, and Wi-Fi everywhere, the triggers are basically impossible to escape.

A weird wrinkle: when the pull becomes a tug-of-war

One of the most interesting findings is that the relationship isn't a straight line. The pull toward internet cues grew stronger as problems got worse, but only up to a point. At the most severe levels, some people started showing the opposite: an urge to avoid the very cues they used to chase.

Why? It mirrors what happens in serious substance addictions. At the extreme end, the cues get tangled up with guilt, regret, and bad consequences. So people feel torn, wanting it and wanting to escape it at the same time. Scientists call this "motivational ambivalence," which is a fancy term for that miserable push-pull of "I need this" and "I hate that I need this."

This matters for treatment, because people at different stages may need different help.

From measuring the problem to fixing it

Here's the hopeful part. Because that automatic pull can be measured, it can also be retrained. The treatment is called approach bias modification, and it uses the same joystick game.

In training, people practice pushing addiction-related images away and pulling neutral or healthy images toward them, over and over. A 2025 trial found that just five sessions over ten days reduced people's automatic pull, lowered their addiction scores, and cut their gaming cravings compared to a fake version of the training.

Even cooler, brain scans showed the training strengthened the brain's self-control regions and weakened the grip of the reward-driven ones. It's like teaching the brain's "brakes" to work better against its "gas pedal." Even a single session reduced the automatic pull and cravings, and it worked below conscious awareness.

Other approaches help too. Cognitive behavioral therapy (CBT), a well-studied talk therapy, remains the most common treatment. One 2025 trial found that CBT combined with mindfulness worked even better and lasted longer than CBT alone.

The bottom line

That irresistible pull toward your screen isn't just a metaphor or a personal weakness. It's a real, measurable thing wired into the same reward and motivation systems behind other addictions. People with problematic internet use develop a stronger and stronger automatic pull toward online cues, driven by a "wanting" system that runs below conscious awareness.

The bright side is that this same pull can be used to identify who's at risk and can be retrained through targeted exercises. Combine that with proven therapies, and there's a real path forward for people stuck in the scroll.

So the next time the phone seems to grab your hand on its own, know this: there's real science behind that tug, and real tools to loosen its grip.

This article is for general education and isn't medical advice. Problematic internet and gaming use can seriously affect work, school, relationships, sleep, and mood — if any of those are taking real damage, a mental health professional can help, and CBT specifically has solid evidence. If screen time is creating conflict with a partner or affecting parenting, that's worth taking seriously even if it doesn't meet a formal addiction threshold. And if you're using screens to cope with depression, anxiety, or loneliness, the underlying conditions deserve attention too — the 988 Suicide and Crisis Lifeline (call or text 988) is free and available 24/7 if things feel overwhelming.
