Ethical Guardrail
Agents must offer commitment devices only when the user explicitly expresses a goal. Must be voluntary and transparent. Never shame users for breaking commitments.
Design Intent
Humans are great at making plans and terrible at sticking to them. A Commitment Device locks in future behavior by raising the cost of deviation. They work by leveraging present bias and loss aversion to protect future selves.
Psychology Principle
Humans are great at making plans and terrible at sticking to them when future temptations arise.
Description
Mechanisms that lock in future behavior by raising the cost of deviation, bridging the gap between today's motivation and tomorrow's action.
When to use
Any long-term goal feature where follow-through is historically low -- fitness goals, savings, learning streaks, project deadlines.
Example
Strava Monthly Challenge + Stickk-style bet: User commits to Run 100 km this month + optional $25 on the line with public leaderboard visibility.
Autonomy Compatibility
Behavioral Objective
Users honor their pre-committed goal because the cost of deviation is now higher.
- Increased follow-through on long-term habits and goals
- Stronger sense of personal accountability
- Reduced decision fatigue on repeated choices

Execution Model
commitment_creation
User voluntarily locks in a specific future behavior.
No commitment is made despite stated goal.
cost_of_deviation
Make breaking the commitment meaningfully costly.
User easily abandons without feeling any real cost.
visibility_and_support
Keep the commitment visible and supported throughout the journey.
Commitment is forgotten until too late.
Failure Modes
Commitment feels too rigid or punitive
Make every device optional and easily adjustable
User sets unrealistic commitments and fails
Agent gently suggests realistic scope before locking in
Social accountability backfires into shame
Keep public commitments opt-in and positive-only
Monetary devices create stress
Cap amounts and require explicit user consent
Overuse leads to commitment fatigue
Limit active commitments per user
Agent Decision Protocol
Triggers
- User expresses a clear long-term goal
- Historical follow-through on similar goals is low
- User asks for accountability or 'help me stick to this'
Escalation Strategy
L1: Diagnose whether a commitment device is appropriate for this goal
L2: Nudge -- offer voluntary commitment with clear opt-out
L3: Restructure -- adjust commitment scope or switch device type
L4: Constrain -- limit active commitments to prevent fatigue
L5: Yield -- flag for human behavioral designer review
Example
User wants to run 3x per week -> agent offers 'Commit publicly to your friends or put $20 on the line -- I'll track it for you.'
Behavioral KPIs
Primary
- % of commitments successfully completed
- Follow-through rate increase vs. non-committed users
- Retention of habit after commitment ends
Risk
- Commitment abandonment or reset rate
- User complaints about pressure or shame
Trust
- User-reported sense of empowerment from commitments
- Autonomy Dial usage when agent offers commitment options

Decay Monitoring
Revalidate when
- User base changes in risk tolerance or financial situation
- New platform features enable stronger commitment mechanics
- Cultural attitudes toward self-binding shift
Decay signals
- Rising commitment reset or abandonment rates
- Drop in user-initiated commitment creation
- Feedback that commitments feel burdensome
