The Cost of Notifications
We tend to price an interruption by its length. A notification takes two seconds to read, so we tell ourselves it cost two seconds. This is the accounting error at the center of modern work.
The real cost is on the other side of the interruption. Psychologists call it attention residue: after you switch tasks, a part of your mind stays behind, still chewing on the thing you left. The two-second glance at your phone doesn't cost two seconds. It costs the two seconds plus the several minutes it takes to fully arrive back at what you were doing — if you arrive at all.
I ran a small experiment this spring. For two weeks I turned off every notification except calls from a short list of people. No badges, no banners, no counts. The first day was uncomfortable in a way I found embarrassing to notice — I kept reaching for a phone that had nothing to say.
By the end of the second week, something had shifted. I wasn't more productive in any way I could put on a chart. But work felt less like wading through interruptions and more like actual thinking. I finished things. I had ideas that needed a long runway, the kind that never survive a buzzing pocket.
The tools aren't going to fix this for us. Every default is set against sustained attention, because sustained attention is bad for business. The good news is that the defaults are only defaults. You are allowed to change them. Almost no one will notice, and the few who do can call.
