Sunk cost, formally

Evidence

Arkes and Blumer (1985) demonstrated that people continue investing in a failing course of action because of resources already spent, even though those resources are unrecoverable and logically irrelevant to future value. Rationally, only future costs and benefits should shape a decision. Emotionally, past investment feels like it must be honored. This is the sunk cost fallacy.

Escalation as a bigger pattern

Evidence

Staw (1976, 1981) coined 'escalation of commitment' for the broader pattern: individuals and organizations pour additional resources into projects, wars, and relationships specifically because they have already committed publicly. Reversal would require admitting that earlier investment was mistaken; escalation preserves the story. The famous case studies — Vietnam, corporate acquisitions that everyone knew were failing — are shaped as much by identity as by economics.

Identity and reputation

Evidence

Escalation intensifies when the decision-maker is personally responsible for the original choice, when the choice is public, and when self-worth is tied to being right. This explains why founders defend failing products, why governments defend failing wars, and why people defend failing relationships long past the point at which a stranger would have stopped.

The 'start fresh' test

KAF Original

The corrective is to ask, seriously: if I were not already in this, would I start it today with what I know now? If the answer is no, past investment is not a reason to continue; it is information about what to stop. The temple version: honor what was learned by leaving; do not stay in order to protect a story of who you were.

Sunk cost
1. You have invested 6 months in a project that no longer looks viable. What is the correct decision test?

Reflect before you answer

Saved to your Journal

1. Identify one commitment — project, relationship, subscription, belief — you would not start today. What is keeping you in it?

2. For that commitment, write the smallest honest exit or renegotiation. Set a decision date.
