Escalation of commitment
Escalation of commitment is the tendency to invest further in a failing course of action to justify what has already been spent.
The deeper people get into a failing course, the harder they find it to stop, and the more they pour in. Escalation of commitment is that doubling down.
Escalation of commitment is the tendency to increase investment in a failing course of action to justify the resources already committed, rather than cutting losses. It is the active, dynamic cousin of the sunk cost fallacy: not merely continuing, but committing more.
Throwing in more, not just staying in
Where the sunk cost fallacy describes persisting with a losing course, escalation describes intensifying it, raising the stakes to vindicate the original decision. The struggling project gets a bigger budget; the losing position is doubled; the failing strategy is pursued harder rather than abandoned. Each new commitment is meant to rescue the previous ones and instead deepens the eventual loss.
Why people escalate
Several forces combine. There is the sunk cost pull and the wish not to waste what is spent. There is the self-justification motive, the need to prove the original decision was right, which makes admitting error feel intolerable. There is the public dimension: having committed visibly, people escalate to avoid losing face. And there is the gambler's hope that one more push will turn things around. Together these can drive intelligent people to pour resources into manifestly lost causes.
Breaking the spiral
Escalation is hardest to stop for the person who made the original decision, which points to the cure: separate the decision to continue from the people invested in the decision to begin. Independent reviews, pre-set limits and kill criteria fixed before emotions are engaged, and a culture that rewards cutting losses rather than punishing the admission of error all help. Naming the dynamic out loud, recognising that this is escalation, can itself break the spell.
Escalation of commitment turns a single bad decision into a series of worse ones, and it lies behind many of the most spectacular failures in business, finance, and war. The discipline it demands, to judge a course by its future alone and to treat stopping as a success rather than a defeat, runs against pride, and pride is exactly what is at stake.
