Commitment Device
The trick isn't willpower. It's making the bad choice structurally impossible.
Grounded in the research on commitment device
Ancient Trick
Odysseus had himself tied to the mast so he could hear the Sirens without steering the ship into the rocks. That's a commitment device: you constrain your future self before temptation arrives. The core insight is thousands of years old — you can't trust future-you in the moment, so present-you sets a trap. Not a motivational trap. A structural one.
The Science Lands
Richard Thaler and Shlomo Benartzi formalized it in 2004 with Save More Tomorrow (SMarT). Employees committed to directing future raises into retirement savings — money they didn't have yet. Participation rates jumped from 3.5% to 13.6% over 28 months. The commitment worked because it happened before the raise hit. Thaler won the Nobel in 2017. This is the backbone of behavioral economics.
