PsychologyLesson on requestFree to read

Quick answer

The Zeigarnik effect is the tendency to remember unfinished or interrupted tasks better than completed ones. Our minds keep nagging us about what's left undone — which is why a half-finished task can stick in your head all day. We remember incomplete tasks better than finished ones.

Key things to understand

  1. We remember incomplete tasks better than finished ones.
  2. The mind keeps 'open loops' active until closed.
  3. It can fuel both motivation and mental clutter.
  4. Writing down tasks can quiet the nagging.
