Memory & Recall
Peak-End Rule
Experiences are judged by their peak moments and the ending.
In practice
Takeaways
- 1
The most intense moment and the final step shape memory.
- 2
Painful endings erase otherwise good experiences.
- 3
Success states should feel intentional and supportive.
Origins
People rarely evaluate an experience by averaging every second of it. They remember standout highs and lows, with special weight on how things ended.
That makes checkout confirmation, error recovery, and cancellation flows disproportionately important.
Design Applications
- Design celebratory but useful completion screens.
- Fix dead-end errors with recovery paths.
- Audit the last step of your highest-value flows first.
