This page is a laboratory, and you are the subject. Run four short experiments on yourself, see your own data, and learn the first principle of fighting back.
Begin the briefing ↓Whatever has happened to your focus over the past decade, it was engineered - by the most sophisticated persuasion machinery ever built.
"The thought process that went into building these applications, Facebook being the first of them, was all about: How do we consume as much of your time and conscious attention as possible?" Sean Parker — Founding President of Facebook, Axios interview (2017)
Billions of dollars are spent engineering the pings, the bright colors, the infinite scroll. The same variable-reward mechanics that keep gamblers at slot machines now live in your pocket. And the machinery works:
of men chose to electrically shock themselves rather than sit alone with their thoughts for 15 minutes.
WILSON ET AL., SCIENCE (2014) · N=42 [1]of women did the same. One participant shocked himself 190 times.
SAME STUDY · SESSION LENGTH 15 MIN [1]average attention span on any single screen today — down from 2.5 minutes in 2004.
MARK, ATTENTION SPAN (2023) [5]That was 2014 — before TikTok, before infinite AI-generated content. Regulation isn't coming to save us, and the companies won't tie their own hands.
What you need is attentional self-defense — and it starts with feeling the attack in your own hands. So: four trials.
Every glance at your inbox mid-task forces your brain to unload one set of rules and load another. Psychologists call the price the switch cost.
David Meyer, co-author of the landmark study on switching, has said those brief mental blocks can cost as much as 40% of someone's productive time [3]. Measure yours.
Two rounds. Round A: tap the numbers 1–8 in order, then the letters A–H in order. Round B: same 16 tiles, but alternating — 1, A, 2, B, 3, C… Ready?
Same 16 taps. The only difference was switching between two simple rule sets — and this is the mildest possible switch. Now imagine brief-writing → inbox → brief-writing.
Adapted from the alternating-task paradigm in Rubinstein, Meyer & Evans (2001) [3]. Errors add time, exactly as they do in the published work.
In a 2015 lab study, merely receiving a notification — without touching the phone — degraded task performance about as much as actively using the phone [4].
Your brain chases the ping whether you check it or not. Feel it happen.
Eight orange targets will appear, one at a time. Tap each as fast as you can. Round 1 is quiet. In Round 2, notifications will arrive. Ignore them. That's the whole test.
slower while "ignoring" notifications. The ping collects your attention either way.
Adapted from the sustained-attention paradigm in Stothart, Mitchum & Yehnert (2015) [4]. In the published study, a notification more than tripled the probability of error.
B.F. Skinner discovered that rewards delivered on an unpredictable schedule produce the highest, most persistent response rates ever measured in a lab [6]. Casinos are built on it. So is pull-to-refresh.
"If you're an app, how do you keep people hooked? Turn yourself into a slot machine." Tristan Harris — former Design Ethicist, Google (2016)
Go ahead — refresh the feed below. See how long you last.
Most pulls gave you nothing — and that's precisely why you kept pulling. Rewards on a variable schedule keep behavior going through long droughts. Your feed runs that schedule, on purpose, forever.

In a 2017 study, researchers measured working memory while participants' phones sat face-down on the desk, in a pocket or bag, or in another room.
The phones were silenced — and in a follow-up, powered off entirely. It didn't matter [2].
Where is your phone right now? Answer honestly.
Bar lengths illustrate the direction of the published pattern, not exact magnitudes [2]. "We see a linear trend that suggests that as the smartphone becomes more noticeable, participants' available cognitive capacity decreases," lead author Adrian Ward explained. Participants insisted the phone hadn't affected them. The data said otherwise.
Here is the counterintuitive part: distance dissolves the craving itself.
When people surrender their phones for a week-long silent retreat, they expect withdrawal. What they typically report instead is almost immediate relief.
Trial 04 is the same principle measured in a lab: proximity drives the pull. Every notch of distance buys back capacity and quiets the urge.
Where does your phone usually live while you work? Place yourself on the gradient.
Slide to your honest position.
Field experiment you can run this week: walk around the block with your phone. Tomorrow, walk the same block without it. Notice the difference in your own hand twitching toward your pocket.
