The Zeigarnik effect is named after the psychologist Bluma Zeigarnik, whose 1920s experiments suggested that people remember interrupted tasks better than completed ones. Later research has been mixed on the memory finding, but the everyday experience it describes is familiar: open loops keep tugging at your attention until you close them or park them.
Why it matters
Unfinished tasks compete for attention while you try to work on something else. Knowing that helps you deal with them deliberately instead of letting them leak into every focus block.
How to apply it
- Before a focus block, write down every open loop that is nagging you.
- When you stop mid-task, note the very next step — it quiets the loop.
- Use it in your favour: stop for the day just before a natural end, so restarting tomorrow is easy.
