Hello guys,
let's talk about your phone and slot machines!

↓

This is what usually happens, right? You open the app for “just a second” and mostly you get .. nothing - a recycled meme, an ad, someone’s lunch, a new protest, a new disaster. But every so often you get a message you were waiting for, a video that makes you laugh out loud, or a comment that actually matters. You just never know what's coming next.

And that's the whole trick actually.

In the 1950s, Ferster and Skinner tested exactly this setup on pigeons and rats. The results? Animals rewarded at random kept going long after the rewards stopped - far longer than animals who’d been rewarded every single time. So, unpredictable rewards build the most stubborn habits.

Psychologists call it a variable-ratio schedule. It’s how gambling works. And it’s how your social media feed works.

Dopamine loves surprise

In 1997, Wolfram Schultz and colleagues recorded dopamine neurons and found that they fire hardest when a reward is better than expected. But let's apply this to your phone.

The buzz in your pocket, the red badge - those become the trigger. So the pull starts before you’ve even opened the app. And because the payoff is unpredictable, every refresh feels like it might be the one that’s worth it. It keeps you in the anticipation phase.

If you have ADHD, there’s evidence your brain weighs immediate, uncertain rewards differently from delayed, certain ones. Which might be why this pull feels so much stronger for you than it seems to for everyone else. (If you’ve ever wondered why “just put the phone down” is advice that works for other people and not you - that’s part of it.)

The mistake: cutting down halfway

This is where it gets counterintuitive, so stay with me 🙂

Most of us try to fix this by checking less. Not quitting - just cutting down. We set a limit on the app: 30 min a day. Sounds reasonable.

But remember what the research showed: intermittent rewards are the hardest to extinguish! So, when you go from checking 50 times a day to checking 10 times, well some of those 10 still pay off. You’ve kept it on exactly the schedule that makes habits most durable - the occasional, unpredictable win.

You’re not loosening the grip; you’re practising the most addictive version of the pattern 🥲 (I've done it too.. many (1000+) times..)

There’s a second effect too. A behavior that seems gone can come back after a break, and psychologists call this spontaneous recovery. If the urge returns after a good week, that doesn’t mean you failed. It’s a predictable part of the process. (just keep this in mind instead of calling yourself weak, and stupid and whatnot)

What Helps

The theme here is simple: stop playing the slot machine, change the machine.

Make it boring. Check at fixed, scheduled times, for example 12:00 and 18:00. Predictable rewards produce far less dopamine surprise, and fixed schedules tend to create a natural pause after each check instead of the constant itch.

Remove the cues. Notifications off and apps off the home screen. Your brain learned to respond to the signal so take the signal away.

Reduce the jackpots. Hide like counts, use a following-only or chronological feed, and unfollow the accounts that occasionally deliver the big hit. A slot machine with fewer jackpots is just less interesting to sit at.

Expect the urge to come back. Plan for it, so when it shows up it reads as “ah, there’s the spontaneous recovery!” and not “I’ve blown it again..”

And the reframe I actually want you to leave with: when you’ve lost an hour to scrolling, you didn’t fail at anything. You responded exactly the way a well-tuned learning system responds to a schedule built to keep you there.

The way out isn’t more willpower. It’s changing the schedule.
