Why Can't I Focus? (It's Not Your Fault)

You pick up your phone to check the time, and twenty minutes later you still don't know what time it is. Your attention isn't broken. It's being pulled, and the research shows exactly how (and how to get it back). You check your phone, find nothing, and check again ten seconds later. You feel a buzz in your pocket while your phone is charging in another room. From the goldfish myth and 47 seconds per screen to the pull of 'maybe', the switching fee and the boredom study where people pressed a shock button, this is the brain science of distraction, plus what research says helps your attention come back. Should phones come with notifications off by default? Yes or no? Tell us in the comments.
