This skill should be used when users drop off mid-task, motivation fades, or experiences feel flat. Applies Peak-End Rule, Goal-Gradient Effect, and Zeigarnik Effect.
Applies these laws from lawsofux.com:
People judge an experience based on how they felt at its most intense point (peak) and at its end, not on the average.
Application:
DESIGN FOR:
1. One memorable PEAK moment (delight, success, wow)
2. A strong positive ENDING
The middle can be mundaneβpeaks and ends are remembered.
Techniques:
Motivation increases as progress approaches the goal.
Application:
SHOW PROGRESS VISIBLY:
- Progress bars accelerate motivation
- "2 of 5 steps" creates momentum
- Artificial starting progress works (start at 20%)
- Breaking into smaller goals = more motivation hits
Techniques:
People remember uncompleted tasks better than completed ones.
Application:
USE INCOMPLETENESS STRATEGICALLY:
- Unfinished profiles pull users back
- Draft states create return triggers
- "You're 80% there" is more compelling than "Complete your profile"
- Cliffhangers in onboarding
Techniques:
Apply these diagnostic frameworks to identify flow issues:
FLOW DIAGNOSIS
Peak-End Rule:
Current peak: [moment] or [none]
Current ending: [experience]
FIX: [add peak at X / improve ending Y]
Goal-Gradient Effect:
Progress visibility: [visible/hidden]
Steps shown: [Yes/No]
Artificial progress: [used/not used]
FIX: [add progress bar / show steps / start at 20%]
Zeigarnik Effect:
Incomplete states: [how handled]
Return triggers: [exist/missing]
FIX: [save drafts / show incomplete / add reminders]
| Stage | Law | Technique |
|---|---|---|
| Start | Goal-Gradient | Show progress from step 1 |
| Start | Zeigarnik | Let them begin before account creation |
| Middle | Goal-Gradient | Break into visible milestones |
| Middle | Zeigarnik | Auto-save, show "draft saved" |
| Peak | Peak-End | Add delight at key success moment |
| End | Peak-End | Celebrate completion, clear next step |
| After | Zeigarnik | Show what else is incomplete |
Onboarding:
Bad: 10 required fields, then "Account created"
Good: Start with win (choose avatar),
show "3 of 5 steps",
end with "Welcome! Here's what you can do"
Checkout:
Bad: Long form, then confirmation email
Good: Progress bar, "Almost done!",
celebration confetti,
immediate order summary
