Commitment Device
A commitment device is a structure an agent adopts to constrain her own future behavior. The smoker who throws away the pack. The writer who disables her internet connection. The team that schedules mandatory offline hours. The organization that builds structured pauses into its workflow. The device works by raising the cost of defection — making it harder or more expensive for the future self to undo the choice the present self has made. In Becker-Murphy's rational addiction framework, commitment devices address the core problem that drives addiction: the agent's discount rate is pushed higher by the consumption itself, making the future self progressively less capable of resisting continuation. A commitment device counters this by installing constraints the future self cannot easily override.
In the AI Story
The Berkeley researchers' proposal for AI Practice — structured pauses, sequenced workflows, protected offline time — is, in Becker's terms, a set of commitment devices designed to counteract the adjacent complementarity of productive AI use. The commitment device works not by reducing the utility of the AI session but by raising the cost of extending it beyond the structured limit. The cost is social (the team norm is to stop), institutional (the schedule enforces the pause), and informational (the pause creates a space in which the accumulated costs of extended use become temporarily visible).
Whether these devices will prove sufficient is an empirical question. Becker's model is not optimistic about the prospects for commitment devices in the face of strong adjacent complementarity, because the same rationality that makes the agent adopt the device also makes the agent circumvent it when the present return is sufficiently high. The smoker who throws away the pack at night buys another in the morning. The builder who sets a timer for two hours disables the timer at one hour and fifty-nine minutes because the feature is almost done and stopping now would waste the context.
The effectiveness of commitment devices depends on how costly they make defection. Individual self-imposed devices are weak because the individual can always undo them. Social commitment devices — team norms, organizational schedules — are stronger because undoing them requires coordination with others who have their own stake in the device's maintenance. Institutional commitment devices — regulations, professional standards, cultural expectations — are strongest because undoing them requires broader social change.
The productive addict faces a problem the substance addict does not: the addiction produces genuine value. The cigarette provides a private pleasure whose cost is borne by the smoker alone. The building session produces code that other people use, products that generate revenue, solutions that serve real needs. The social cost of intervening is visible and immediate: lost output, delayed shipment, reduced competitiveness. This asymmetry is the deep structural reason why productive addiction commitment devices are harder to build than substance addiction ones.
Origin
The formal analysis of commitment devices in economics developed through Thomas Schelling's work on self-command in the 1970s and 1980s, elaborated in game-theoretic terms and applied across domains from savings behavior to smoking cessation. The application to rational addiction extends Becker-Murphy's framework by identifying the specific leverage points at which the discount-rate dynamics can be interrupted.
Key Ideas
Raising the cost of defection. The device works not by reducing the utility of the addictive consumption but by making continuation beyond the limit more expensive.
Social devices are stronger than individual ones. Commitment that requires coordination with others to undo resists defection better than commitment that depends on individual willpower.
The productive addiction asymmetry. Because productive addiction generates genuine economic value, social commitment devices face resistance that substance-addiction devices do not encounter.
Institutional commitment devices as dams. The structures the transition requires must operate at institutional scale to survive the pressure of individually rational circumvention.
