The Sunk-Cost Cockpit

1. INSTALL POINT

   This program first installs when the hidden rule gets confirmed by experience. Something happened — a moment where the belief proved itself correct. The mind files it away: this is how things work.

2. REINFORCEMENT

   Each avoidance that works, each praise withheld, each perfect thing left unstarted — the loop tightens. Every confirmation adds another layer. The script runs faster, quieter, until it sounds like your own voice.

3. NOW

   Today it runs on autopilot. “Two years in means two years owed — turning now would make it all a waste.” Escalation-of-commitment research is blunt: the more we've sunk, the harder we grip a failing course, and founders — whose idea is their identity — grip hardest. The market doesn't refund conviction.

RESEARCH EVIDENCE

1. 1976

   Barry Staw publishes 'Knee-deep in the Big Muddy,' the foundational experiment on escalation of commitment: participants who felt personally responsible for an initial investment continued to allocate more resources to it even as evidence of failure mounted — establishing that prior sunk costs, not expected returns, drive many continuation decisions. ↗
