Why can't I stop scrolling?

The short version: you can’t stop scrolling because the feed never gives you a place to stop. Each swipe might bring something good, the app keeps learning what holds your attention, and opening it has become a habit that fires on cues like boredom. Stopping gets easier when you put back what the feed removed: an end point, fewer cues, a small obstacle, and something else to do.

The feed has no last page

A book has chapters. A TV episode ends. A newspaper runs out of pages. Each of those gives you a moment where stopping is the default and carrying on is a choice. Infinite scroll and autoplay take that moment away. The next post loads before you’ve decided whether you want it, so stopping becomes the thing you have to choose, over and over.

Researchers at Ulm University followed 46 people for a week and logged 6,605 sessions in Facebook, Instagram, TikTok, Reddit and Twitter. They describe two loops. The inner one keeps a session going once you start scrolling. The outer one is the habit that brings you back to the app again and again. Most of the reasons people gave for ending a session came from outside the app: a task, another person, a basic need. The feed rarely gave them a reason to leave.

A study of YouTube users points the same way. In a survey of 120 people in the US, autoplay and recommendations mostly lowered people’s sense of being in control of their viewing, while search and playlists raised it. When you pick what to watch, you tend to stop when you’re done. When the app picks, there is no done.

The next post might be the good one

Most of what you scroll past is forgettable. Every so often something is funny, useful or about someone you know. You can’t predict which swipe will bring it, and that uncertainty is part of the pull. Psychologists call it partial reinforcement: a behaviour that is rewarded only some of the time is harder to drop than one rewarded every time. Critics of the tech industry have compared the feed to a slot machine for this reason.

The comparison is a useful picture, but be careful with how far it goes. The best direct evidence is about posting, not scrolling. A 2021 study in Nature Communications analysed over one million posts from over 4,000 people across several platforms and found that people timed their posts in a way that fits reward learning, with likes as the reward. That supports the idea that social rewards shape how we use these apps. It doesn’t prove that each swipe works like a pull on a lever, and claims about a “dopamine hit” per post go further than the research does.

The app learns what keeps you watching

A chronological feed of friends runs dry. A recommended feed doesn’t, because it can draw on everything posted by anyone. TikTok explains that its For You feed weighs your interactions (what you like, share, follow and comment on), details of each video like captions and sounds, and to a lesser degree your device and language settings. One of the strongest signals it names is whether you watch a longer video all the way to the end.

So the more you watch, the better the feed gets at showing you things you’ll watch. That’s convenient when you want to be entertained and a problem when you want to stop, because the content that comes next has been chosen for you.

Your thumb opens the app before you decide to

A lot of scrolling doesn’t start with a decision. A 2012 study by researchers at Aalto University described a checking habit: a quick look at the phone, usually under 30 seconds, opening one app. These checks didn’t happen at random. They were tied to a small set of situations, like reading email while commuting or checking news when bored. People in that study didn’t describe it as addiction. They called it overuse and an annoyance.

We also check far more than we think. In a 2015 study, 23 people had their phone use tracked for two weeks. They used their phones about 85 times a day, for about five hours in total, and 55% of those uses lasted less than 30 seconds. Asked to estimate, they guessed about 37 times a day, and their guesses didn’t match what the phone recorded. It was a small sample, but the gap is hard to ignore.

Each quick check is a chance for the inner loop to start. You open the app to look at one thing, and the feed is right there.

Boredom does a lot of the work

The phone is the easiest way out of a dull moment: a queue, an ad break, the minute before a meeting. A 2025 systematic review of 28 studies found that people who get bored easily are more likely to report problematic use of smartphones, social media and games. Nearly all of those studies were cross-sectional, which means they show a link, not that boredom causes overuse. Still, the pattern fits what people describe. The scroll fills the gap, and then it keeps going after the gap has closed.

Why it’s harder at night

In the Ulm study, most sessions ended because something outside the app called people away. At night, in bed, nothing does. There’s no meeting, no bus stop, no one asking for you. You’re also tired, and tired is a bad state for stopping anything.

Researchers have a name for staying up when nothing is keeping you up: bedtime procrastination. In a survey of 177 people, it was linked to lower self-control and to getting too little sleep. For what to do about the late-night version, see our guide on how to stop doomscrolling before bed.

Is it an addiction?

You’ll see “scrolling addiction” everywhere, but the science is less settled than the headlines. A 2018 review in the Journal of Behavioral Addictions looked at the case for smartphone addiction and concluded that the research doesn’t support calling it addiction. The authors suggested “problematic use” instead, and argued the consequences usually don’t reach the severity of addiction.

That matters less than it sounds. You don’t need a diagnosis to decide you want your evenings back. And if the problem is mostly design and habit, then changes to design and habit should help, which is what the research on fixes suggests.

What follows from each cause

• No end point, so add one. Decide the stop before you start: a set number of minutes, one video, the end of a chapter. Turn off autoplay where the app allows it, and use search or a following-only feed instead of recommendations when you can.
• Cues start the habit, so remove them. Turn off notifications for the apps you overuse, move them off your home screen, and keep the phone out of reach at the times you check without thinking.
• Opening is automatic, so add friction. A small obstacle gives you a second to decide. In a six-week study of the app one sec, which shows a short pause before a chosen app opens, 280 people closed the app again 36% of the time, and their openings of those apps fell by 57% by the end.
• Boredom pulls you in, so replace the habit. Give the same moments a different default: a book, a walk, a call. Expect it to take a while. In a study of 96 people building a new daily habit, the time it took to become automatic ranged from 18 to 254 days, and missing one day didn’t derail it.

Where FirstPage fits

You may not need an app for any of this. Android’s Digital Wellbeing can set a daily timer for an app for free, a phone charging in another room removes most cues, and a paper book is the best replacement there is. Try those first.

If you want the end point, the friction and the replacement in one place, FirstPage is a reading app blocker for Android. You pick the apps to lock, such as Instagram, TikTok or YouTube, and set a daily reading goal in pages or minutes. Until you’ve read today’s goal, opening a locked app shows how many pages are left and a button back to your book. The book has a last page, and the feed waits until you’ve reached it.

You can also lock everything on purpose for 30 minutes, an hour or two hours, and the stats show your reading time next to your time on social apps, day by day. The free version covers two locked apps and one book. If you’d rather skip the lock, it works as a plain reading habit app with a goal, streak and reminders. For a comparison with other apps like it, see the best reading app blockers.
