Commitment Device
When your future self cannot be trusted to resist a predictable temptation, transfer enforcement to a person, rule, tool, or cost that the tempted self cannot casually override.
A saint does not need to wake up intending to become a murderer. The danger is a sequence of smaller permissions, each easy to grant from inside the moment. The countermeasure is surprisingly blunt: put the control in somebody else’s hand before the slide begins.
E1Remove the future veto
A commitment device separates two decision-makers who share one body: the planning self, which sees the slope, and the future self, which will face the immediate reward or pressure. The planner uses the present circle of control to alter the later choice architecture—delegating authority, automating a cutoff, or attaching a cost—so temptation must overcome an external barrier rather than merely an internal promise. Unlike escalation-of-commitment, which traps you through accumulated investment, this mechanism deliberately creates friction in service of a decision made while judgment is clearer.
E1The lock can preserve the wrong decision
External enforcement is only as wise as the choice made before it. If circumstances change or new evidence appears, a rigid device can suppress useful uncertainty-driven-exploration and turn foresight into captivity. Preserve a review route for genuine changes in information, but do not let momentary temptation masquerade as one.
Name the gatekeeper tonight
Choose one recurring temptation and identify the exact point at which you usually reverse your earlier intention. Before that point arrives again, transfer one relevant control to a named person or an automatic rule—for example, access, spending authority, or a cutoff—and specify in advance the narrow conditions under which it may be released.
