Your phone buzzes. You're in the middle of homework, or a conversation, or just thinking — and the little sound pulls your eyes straight to the screen. You tell yourself you'll just check. Twenty minutes later you surface, and you can't quite remember what you were doing before. This happens all day. Buzz. Look. Lost. The notifications feel urgent — like something is happening that you have to know about right now. Mostly, it turns out, nothing was. It's like there's an invisible string between the phone and your attention, and the phone keeps tugging it.
