The Zeigarnik effect is the psychological phenomenon wherein people remember uncompleted or interrupted tasks better than completed ones. It operates through cognitive tension: an uncompleted task creates a mental state of unresolved tension that persists until the task is completed or consciously abandoned. The mechanism functions through working memory prioritization of incomplete goal-sequences, making unfinished tasks more salient in consciousness. This effect has been demonstrated across repeated laboratory experiments and applies to both mundane and meaningful tasks.

The Zeigarnik effect describes how incomplete tasks persist in active recall. Remove working memory — the incomplete task cannot be actively maintained, and the effect ceases to operate. This passes the present-tense removal test of Law 8: the effect literally requires working memory to function, not merely to be said.
