Mind & EverydayHow it works
How a feed keeps you without you noticing.
Three mechanisms interlock. Variable reward: you never know if the next post is good, so you keep scrolling. No stopping cue: infinite loading removes the natural end of a page or newspaper. Negativity bias: threatening content grips you more than neutral content. Together they form a loop driven by your attention rather than your intention.
Useful: Build in an ending: a timer, a fixed number of posts, or the phone in another room.
