The mechanic had been clear: the engine was beyond economical repair. She had already spent two thousand dollars on parts over the past several months. Each time a new problem surfaced, she bought another component, convinced that one more fix would finally stabilise the car.
Friends recommended a used sedan. She dismissed the suggestion. Walking away would mean admitting that the two thousand dollars was gone - that the decision to repair rather than replace had been wrong from the start. One more part. One more attempt. The car was almost there.
It was not almost there. The repairs continued, and so did the costs.
What It Is
Escalation of commitment is the tendency to continue investing resources into a failing course of action because of prior investments, despite evidence suggesting that stopping would be the better choice. Also known as the sunk cost fallacy, it describes a pattern where the driving force for continued investment is not rational expectation of future returns but a psychological need to justify past commitments.
Escalation of commitment leads to greater financial losses in business projects that continue despite negative feedback. The prior investment - money, time, effort, reputation - becomes the reason to continue, rather than the expected value of continuing.
The Mechanism
Four psychological processes reinforce each other.
Self-justification and cognitive dissonance. People escalate to reduce cognitive dissonance and avoid admitting personal responsibility for a mistake. A decision that is now failing was still made by the same person who is evaluating whether to stop. Stopping means confirming that the decision was wrong. Continuing preserves the possibility - however diminishing - that it was right.
Loss aversion. Abandoning an investment means accepting a definite loss. The psychological pain of a certain loss is greater than the expected pain of a potential further loss. Continuing at least keeps the outcome uncertain.
Regret and blame avoidance. Stopping triggers regret about having started. Continuing defers that regret, keeps it hypothetical. In organisational contexts, stopping also creates accountability - someone decided to stop a project - while continuing distributes that moment across future time.
Illusion of control. A belief that additional effort can turn the situation around. If only one more repair, one more sprint, one more investment - the downward trajectory could reverse. The prior investment is reframed as evidence of commitment rather than evidence of a poor return.
Where It Shows Up
Business and organisational projects. Projects that have missed deadlines, overrun budgets, and produced negative early results are routinely continued because of the scale of prior investment. The language changes - "we've come too far to stop" - but the mechanism is the same.
Government and public policy. Large infrastructure projects, military interventions, and institutional programmes have historically continued long after evidence indicated they would not achieve their stated goals, partly because discontinuation would require acknowledging that prior investment had been wasted.
Personal decisions. A relationship that has required sustained unhappy effort. A degree programme that stopped feeling right two years in. A property purchase that turned out badly. The prior investment makes stopping feel more costly than it objectively is.
What It Is Not
Escalation of commitment is not about money alone. It applies to time, effort, emotional investment, and professional reputation. Any prior investment can become the reason to continue escalating.
The behaviour is also not rational in most contexts. The idea that continued investment is justified if future prospects might improve misunderstands the mechanism - the escalation tends to persist even when objective forecasts remain negative. It is driven by the psychology of past investment, not by analysis of future outcomes.
