Underneath every feed are two systems being played against you at once. The first is dopamine — which, contrary to popular belief, isn't the pleasure chemical at all. It fires on anticipation, not reward: the seeking, not the getting. Pair that with unpredictable rewards (the design principle behind every slot machine — and the phone in your pocket). The second system is older still: your social brain, which reads a like or an unanswered post as ancient survival data about whether the group still wants you. We'll also look at the real cost — about 23 minutes to fully refocus after an interruption — and what actually helps.
