Zeigarnik effect
The Zeigarnik effect is the observation that interrupted or unfinished tasks are remembered better and intrude on attention more than completed ones. It comes from Bluma Zeigarnik's 1927 studies, and while the memory effect has replicated inconsistently since, the everyday experience it names, open tasks nagging at you, is widely recognised.

Why it matters for procrastination
Two practical readings survive the shaky evidence. First, just starting a task, even for a few minutes, tends to convert it from a dreaded abstraction into an open loop your mind keeps returning to, which lowers the cost of resuming. Second, Masicampo and Baumeister (2011, Journal of Personality and Social Psychology) found that simply making a concrete plan for an unfinished task reduced its intrusiveness, which supports writing a specific next step before you stop for the day. A caution: the original memory findings have a mixed replication record, so treat the effect as a useful heuristic rather than a law.

Frequently asked questions
Is the Zeigarnik effect real?
The honest answer is partly. Zeigarnik's original 1927 memory advantage for interrupted tasks has failed to replicate in several later studies, so the strong claim is doubtful. The weaker claim, that unfinished goals occupy attention until you finish them or make a concrete plan, has better modern support.
