In practice
Takeaways
- 1
Incomplete states create psychological pull to finish.
- 2
Show what remains, not only what is done.
- 3
Draft indicators help users resume confidently.
Origins
The Zeigarnik effect suggests unfinished tasks occupy attention more than completed ones. Progress surfaces that highlight remaining work can motivate return visits and completion.
Used ethically, this supports productivity; used poorly, it becomes nagging.
Design Applications
- Display “3 steps remaining” in setup flows.
- Preserve drafts with clear resume entry points.
- Use profile completion meters with transparent value.
