Engineered Hook
A design element built specifically to capture and hold attention beyond the user's intent — autoplay, infinite scroll, variable-reward notifications. The hook is not a flaw; it is the product working as designed.
The word I want to defend here is engineered. A hook is not an accident, not a bug, not a regrettable side effect that someone is rushing to patch. It is the feature. Autoplay, the infinite scroll, the pull-to-refresh that resolves like a slot-machine lever, the notification that arrives on a variable schedule — each was designed, tested, and shipped because it raised the metric it was meant to raise.
The clearest lineage runs through gambling. Natasha Dow Schüll's study of machine design showed that the "zone" players describe — time dissolving, the world narrowing to the next pull — is not a happy accident of the games but the explicit target of their design (Addiction by Design, 2012). The variable-reward schedule that keeps a player at a machine is the same mechanism behind a feed that refreshes to something new every time you tug it.
I should steelman the other side, because there is one. Many of these features genuinely improve the experience — autoplay can be a kindness when you want the next episode. The problem is not that hooks exist; it is that they are optimized against your stated intent rather than for it. The feed wants one more minute even when you've decided you're done.
To name a hook while it has you is to break the zone for a second. That second is the whole opening.
