The Ulysses Contract and the Snooze Button
Odysseus ordered his sailors to tie him to the mast so his future self couldn't undo what his present self intended. Behavioral economists call this a commitment device. It works for getting out of bed too — if you design it right.

A commitment device is a deliberate constraint a person places on their future self, designed to enforce a decision made by their present self when motivation was higher. Research consistently shows that commitment devices work — but their effectiveness depends heavily on whether enforcement is internal (self-monitored) or external (enforced by another party or system), with external enforcement producing substantially better outcomes.
When Odysseus sailed past the Sirens, he didn’t trust himself. He ordered his crew to lash him to the mast, fill their own ears with beeswax, and ignore whatever he shouted once the music started. His present self built a constraint that his future self couldn’t override. The sailors followed instructions. He survived.
Behavioral economists Richard Thaler and Shlomo Benartzi named this general class of strategy in the academic literature, but the design principle is ancient: you solve the problem of a weaker future self by acting before that self arrives.
Mornings are a particularly demanding context for commitment devices. The self who set the alarm and the self who hears it are the same person in different states — different neurochemistry, different arousal levels, different access to motivation. The alert evening self made a decision; the half-asleep morning self gets to override it. That asymmetry is the problem. Commitment devices shift power back toward the decision-maker.
1. The Witness Design
The simplest and most studied external enforcer is another person.
Dan Ariely’s work at Duke University on precommitment and future-self discounting consistently finds that social accountability changes behavior in ways that private resolve doesn’t. The logic isn’t complicated: when someone else knows what you intended to do, failing to do it carries a cost beyond the internal. There’s a reputational stake. And reputation, unlike willpower, doesn’t deplete at 6 a.m.
The Witness Design applied to waking: tell a specific person your target wake time and require yourself to report in when you hit it. Not a vague “I’m trying to wake up earlier” disclosure — a precise commitment to a specific time, reported to a specific person, with a defined check-in. The more immediate and concrete the report, the more effective the constraint.
Accountability and commitment aren’t the same thing, but they work well in combination: commitment specifies what you’ll do, and accountability makes visible whether you did it.
2. The Financial Design
Money changes the cost calculation in a way that social stakes alone don’t always reach.
Thaler and Benartzi’s 2004 “Save More Tomorrow” program — one of the most rigorously studied commitment devices in behavioral economics — enrolled employees in a plan where retirement contributions automatically increased with each pay raise. After three and a half years, average savings rates climbed from 3.5% to 11.6%. Participants saved roughly three times more than control groups. The design worked because it committed future income before it was felt as current income.
The same principle applies to behavior commitments. StickK.com, a commitment contract platform, publishes data showing financial-stakes commitments complete at roughly three times the rate of non-financial ones. Beeminder operates on a similar model: you define a goal and a schedule, and the platform charges you real money when you break it.
Applied to waking: deposit money into an account that releases to a cause you actively dislike if you fail to wake by a specified time. The activation cost has to be real — nominal amounts don’t produce the friction needed to make the device meaningful.
3. The Physical Arrangement Design
The classical version of this is placing the alarm across the room so you have to get up to turn it off. The observation is obvious; what’s less obvious is why it works as consistently as it does.
The answer isn’t simply that you’re physically awake by the time you reach the alarm. It’s that the design removes one decision from the groggy self’s jurisdiction. The choice isn’t “should I get up?” — the body is already up. The choice collapses to “should I go back?” — a structurally different question asked from a standing position, with slightly more arousal and slightly more momentum against the alternative.
Physical arrangement design generalizes: put the coffee maker across the apartment. Put your gym bag at the front door. Put your work clothes somewhere that requires you to be in the kitchen to retrieve them. Each physical placement is a micro-commitment made by the alert self that nudges the sleepy self along a chosen path with less deliberation required.
The key constraint is that the arrangement has to be set the night before — by the self with access to forward planning.
4. The Identity Declaration Design
Public statements about who you are constrain future behavior differently than statements about what you’ll do.
This distinction matters. “I’m going to wake up at 6 a.m.” is a behavioral intention. “I’m someone who gets up when the alarm goes off” is an identity claim. The violation costs are different: behavioral intentions are broken routinely and forgiven easily; identity claims, when made publicly and specifically, carry a heavier consistency requirement.
Robert Cialdini’s research on commitment and consistency — documented extensively in Influence — demonstrates that written and public commitments produce stronger follow-through than private ones, and that identity-level statements produce stronger follow-through than behavioral ones. The specificity matters: “I’m an early riser” is vaguer and less binding than “I wake at 5:45 every weekday.”
The failure mode to avoid here is the guilt loop: identity declarations that are too ambitious create fragility, because a single failure becomes a self-concept threat rather than a behavioral lapse. Effective identity design scales to something you can actually execute, then tightens incrementally.
5. The Algorithmic Design
The most robust commitment devices are ones that don’t require you to make a choice in the moment, because the system has already made it for you.
Consider how git handles version history: commits are immutable. You can’t silently overwrite a commit once it’s been pushed to a shared repository. The write-once property isn’t just a technical constraint — it’s a commitment device baked into the tool. Future-you can’t revise the record.
Algorithmic design applied to waking means pre-deciding and automating as much as possible the night before. Calendar blocks that auto-mark you unavailable until a certain time. Smart home automations that turn on lights and increase room temperature at a fixed time. Work commitments — a 7:00 a.m. call that you scheduled two weeks ago — that effectively precommit you to a wake window whether or not you feel like it.
The limitation of algorithmic design is that most wake-up contexts still require a final human action. You can automate the cues but not the getting out of bed. Algorithmic design is best combined with another mechanism that addresses the execution gap directly.
6. The Collaborative Design
A Ulysses contract that commits two people simultaneously is structurally harder to break than one that only commits one.
The design: two people share a wake target and link consequences. If one fails, both lose something. The social cost is no longer “my friend will know I failed” — it’s “my friend will also suffer because I failed.” Mutual loss changes the calculation. You’re not just managing your own motivation; you’re being held by someone else’s stake.
This is distinct from the Witness Design, where the witness has no skin in the game. The Collaborative Design requires that both parties have something at risk, which creates a more durable enforcement structure. Trust compounded with shared stakes produces different behavior than trust alone — the relationship itself becomes part of the commitment architecture.
Practical implementations: two people commit to the same wake time and must video-check-in within five minutes. Failure by either party costs both an agreed-upon amount, or triggers an agreed-upon consequence. The specificity of the consequence matters more than its magnitude.
Frequently Asked Questions
What makes a commitment device actually work vs. fail?
External enforcement is the primary differentiator. Commitment devices that rely on you monitoring your own compliance have a structural weakness: you can renegotiate with yourself at any moment. Devices that involve another person, a financial stake, or an automated system remove your authority over enforcement. The research — including Ariely’s precommitment studies and StickK’s completion data — consistently shows external enforcement outperforms internal monitoring.
Isn’t this just willpower by another name?
No, and the distinction is important. Willpower is an in-the-moment resource that depletes and fluctuates. Commitment devices are structural interventions made before the moment of temptation, designed so that the depleted future self doesn’t need to exercise willpower. Thaler and Benartzi’s Save More Tomorrow program worked precisely because it didn’t ask employees to repeatedly choose to save — it moved the decision upstream and automated the outcome.
How do I pick the right design for my situation?
Match the design to where your constraint actually breaks down. If you turn off the alarm and don’t remember doing it, physical arrangement or algorithmic design addresses the execution gap. If you remember turning it off but justify going back to sleep, financial or collaborative design adds costs to the justification. If you’re consistent some weeks and not others, identity declaration adds durability to periods of lower motivation. Most robust implementations combine two or more designs from different categories.
