zeigarnik_effect
The tendency to remember uncompleted or interrupted tasks better than completed ones. The human mind creates a kind of cognitive tension for unfinished tasks, keeping them active in memory until resolution. Once a task is completed, this tension dissipates and the memory fades more quickly.
A waiter can remember complex orders for multiple tables while they are being served, but struggles to recall any details of those orders once the meals have been delivered and the checks paid.
A programmer leaves a bug half-fixed at the end of the workday and finds themselves mentally running through possible solutions during dinner and even in the shower — yet once the bug is resolved the next morning, they barely recall the specifics of the problem.
A novelist who stops writing mid-chapter finds the unfinished scene lingering in her mind all evening, with dialogue and plot ideas surfacing unbidden. Once she completes and publishes the chapter, those details fade almost entirely from memory.
Binary (yes/no) questions an LLM must answer to identify this aspect:

Unfinished tasks create a state of cognitive tension that keeps them accessible in working memory. This may have evolved to ensure important unfinished goals are not forgotten, functioning as an internal task management system.
Use this effect productively by starting tasks to create cognitive commitment. If intrusive thoughts about unfinished work are causing stress, write down a specific plan for completing the task — research shows this reduces the effect.
The Zeigarnik effect is used in cliffhangers in television and serialized fiction, in gamification and progress bars, and by productivity systems that advocate starting tasks even when you can't finish them.
