The room remembers the routine

A cinema can produce a hand reaching for popcorn even when the popcorn is stale. Wendy Wood uses such findings to show how repeated behaviour becomes tied to context: a place, time, preceding action, or familiar object can prompt a routine with little deliberation. The environment begins carrying part of the memory.

This does not make people puppets, and laboratory snacks are not every habit. Motivation matters especially when circumstances are new. But intention is often asked to fight on terrain already arranged for repetition. Moving the bowl, changing the route, or shifting the first minute after arriving home can matter because a cue has changed—not because character suddenly has.
