Ethical Guardrail
Agents must never use fake curiosity. Always deliver on the promise once the gap is closed. Never withhold information the user needs to make an informed decision.
Design Intent
The human brain cannot tolerate an information gap. When we know something is almost known but not quite, we feel a powerful itch to close the gap. Curiosity Gap deliberately creates a small, intriguing information void right before a desired action.
Psychology Principle
The human brain cannot tolerate an information gap. When we know something is almost known but not quite, we feel a powerful itch to close the gap.
Description
Deliberately creates a small information void right before a desired action, leveraging the brain's drive to resolve uncertainty.
When to use
Any prompt, teaser, or entry point where engagement or click-through is low -- feature discovery, content feeds, notifications.
Example
Duolingo Lesson Tease: 'Your friends are learning Spanish... you're only 3 lessons behind them' + one-tap 'Catch up now'.
Autonomy Compatibility
Behavioral Objective
Users take the target action to resolve the curiosity gap they feel.
- Higher open and click-through rates on prompts
- Increased voluntary engagement with new features
- Stronger sense of discovery and delight

Execution Model
tease_creation
Give just enough context to spark a specific question.
User feels no emotional pull to learn more.
gap_highlight
Make the missing piece feel tantalizingly close.
User sees the tease but is not curious enough to act.
easy_closure
One-tap or one-second action to resolve the gap.
User wants to close the gap but the action feels like work.
Failure Modes
Gap feels like clickbait
Always deliver real high-value information
Curiosity is too vague
Make the gap personally relevant and specific
Reveal is disappointing
Ensure the payoff exceeds the tease
Overuse causes curiosity fatigue
Limit gaps to 2-3 per session
Gap hides critical information
Never withhold safety, legal, or high-stakes details
Agent Decision Protocol
Triggers
- Engagement on a new feature or prompt is low
- User is scrolling past opportunities
- User says 'I'm not sure if I need this'
Escalation Strategy
L1: Diagnose low engagement via behavioral_signals
L2: Nudge -- add a personalized curiosity tease with one-tap closure
L3: Restructure -- redesign the entry point with a specific, relevant gap
L4: Constrain -- limit to 2-3 curiosity gaps per session to prevent fatigue
L5: Yield -- flag for human behavioral designer review
Example
User hasn't reviewed their weekly summary -> agent shows 'Your project saved 14 hours last week... here's the one change that made it possible' with one-tap reveal.
Behavioral KPIs
Primary
- Click-through rate on curiosity-teased elements
- Time from tease to resolution
- Session depth after closing a gap
Risk
- User reports of 'tease and disappoint'
- Dismissal rate of curiosity prompts
Trust
- User-reported excitement after resolving gaps
- Autonomy Dial usage when agent creates gaps
Behavioral Signals

Decay Monitoring
Revalidate when
- User base becomes desensitized to common teaser styles
- Platform algorithms change content visibility
- New content types are introduced
Decay signals
- Declining click-through on teased content
- User feedback that 'everything feels like a tease'
- Drop in perceived value after resolving gaps
