KembaraXtra – Psychology: Concorde Fallacy

Definition

The Concorde fallacy is the tendency to continue investing time, money, effort, or emotion in a project because of resources already spent, even when future investment is no longer rational. It is more commonly known as the sunk cost fallacy.

Decision-Making Mechanism

Past costs are irrecoverable and should not determine present choices, but people often feel compelled to justify them. Abandoning a project may be experienced as admitting failure or wasting previous investment. This emotional reaction can lead to further commitment despite worsening evidence.

Role in Cognitive and Social Psychology

The fallacy has been studied in gambling, business, war, relationships, education, and animal behaviour. It illustrates how decisions are influenced by loss aversion, self-justification, anticipated regret, and commitment. The effect may be especially strong when responsibility for the original decision is personal.

Applications and Prevention

A more rational approach is to compare only expected future costs and benefits. Independent review, predetermined stopping rules, and explicit consideration of alternatives can reduce escalation of commitment. The term derives from continued British and French investment in the Concorde aircraft project despite increasing economic concerns.

Summary

The Concorde fallacy is continued investment motivated by past costs rather than future value. It is also called the sunk cost fallacy. The bias can affect financial, interpersonal, and organizational decisions. Focusing on future consequences helps reduce it.
