The Endowed Progress Effect
Two loyalty cards, eight car washes of real work either way. The card that arrived with two stamps already filled in got completed almost twice as often.
A car wash handed out two loyalty cards. One needed eight stamps for a free wash. The other needed 10, but arrived with two already stamped.
Identical work: eight washes either way. Completion came out at 19 percent for the eight-stamp card and 34 percent for the pre-stamped one. Nearly double, for a head start that was pure decoration.
The mechanism is that people don't respond to the distance left to a goal. They respond to the fraction of it already covered. Zero of eight is a standing start. Two of 10 is something underway, and abandoning something underway registers as losing ground rather than as declining to begin.
Most workplace programs are built as standing starts. Empty training path, blank profile, zero of 12 modules complete, day one of a 90-day plan. Each one announces that nothing has happened yet.
The nudge: Credit what people already did. Open the onboarding checklist with the items completed during hiring already ticked. Start the development plan with the skills they arrived holding. The work ahead is unchanged. The story about it isn't.
