Escalation of commitment is a pattern where people pour more time, money, or effort into a failing project despite clear evidence that it will not succeed. It happens because walking away forces the person who started it to admit they were wrong. Continuing lets them protect their reputation and justify their original choice, even when stopping would cost far less.
By the edgi team We find the most surprising true thing about an idea and build a 60-second lesson around it.
Pete Seeger has a song about a platoon wading a river on a practice patrol. The water reaches their necks and the captain keeps saying push on. The captain is the one who drowns. Barry Staw borrowed the title for the founding study. He sat business students down with a fictional company and had each of them hand research money to one of its two divisions.
Later in the story, the division they had chosen was doing badly. They were handed $20 million more and told to place it wherever they liked. They put an average of $13.07 million of it straight back into the division they had watched fail.
It is the decision, not the money
Other students in the same study inherited the failing division as somebody else's decision. Same case, same losses on the page, and they moved the money out far more readily. So the money already spent is not what holds people. It is identical in both versions. What differs is who has to be wrong for the project to stop.
If you approved it, cancelling it files a public verdict on your judgement, and continuing files nothing at all. The cheapest way to go on being right is to go on. Psychologists call it self-justification. It is what separates escalation of commitment from throwing good money after bad: you are defending your own judgement, not the investment.
Who should be asked
Which tells you who is least able to make the call: whoever made the last one. The question "should we keep going?" is one question for a new hire and two questions for the founder. The second question is "was I right?" It gets answered first, quietly, before anyone says anything out loud about the project.
So put the question to somebody who was not in the room when it started. They are the only person who can answer it about the project.
How escalation of commitment happens
A typical escalation occurs across three stages. First, a leader commits substantial resources like time, money, or staff to a specific course of action. Second, the project runs into trouble, failing to meet expectations or slipping into decline. Third, the leader faces a choice: cut losses and cancel the project, or pour in more resources to push it through to completion.
When faced with this choice, standard economic reasoning says to weigh future costs against future benefits. Escalation happens because leaders instead use past, unrecoverable resources to justify new spending. This violates standard cost-benefit logic and persists even when better alternatives exist.
Why self-justification drives the trap
The psychological driver behind escalation is self-justification. Managers strive to keep their current actions consistent with their past choices. If an outside party or a team member sees inconsistent decision-making, it threatens the manager's authority and status.
To protect their role, leaders recall and prioritize information that supports their past behavior. They try to prove to themselves and their peers that their initial choice was sound. The need to avoid public failure often outweighs the objective facts of the failing project.
Escalation in government and policy
Escalation of commitment extends far beyond corporate budgets into international politics. In 1965, U.S. diplomat George Ball warned President Lyndon Johnson about deepening military involvement in the Vietnam War.
Ball pointed out that once large numbers of troops took heavy casualties, backing out would feel impossible without national humiliation. The heavy costs already paid would lock the nation into an open-ended commitment, forcing leaders to chase complete objectives long after success became unlikely.
Test yourself
You are put in charge of a project you argued against from the start. Now what?
You can kill it cleanly, because ending it proves you were right. Escalation needs your own judgement on the line. Here the judgement on the line points the other way, so the one thing that normally makes a project impossible to stop is the thing making it easy.
A friend is two years into a course she dislikes. Which question gets the most honest answer?
"Would you enrol today?", because it lifts her out of the original choice. Two of these ask her to weigh what is already gone, which is the thing she cannot weigh honestly. The other hands the decision to somebody who never made it, and on this one day that person is her.
Escalation of commitment is primarily driven by future profit projections rather than past resource allocation.
False. A hallmark of this bias is that decisions are heavily influenced by 'sunk costs', what has already been spent, rather than future utility.

What is the difference between escalation of commitment and the sunk-cost fallacy?
The sunk-cost fallacy is the general economic tendency to justify new investments using unrecoverable past costs. Escalation of commitment focuses on the behavioral and social drive to protect one's personal judgement and past choices.
What is de-escalation of commitment?
De-escalation of commitment is the reverse process, where individuals or organizations successfully reduce or withdraw support from a failing initiative. Researchers study it through tools like mental accounting and formal budgeting limits.
What is expectancy theory in this context?
Expectancy theory explains how decision-makers assess the likelihood that additional resources will achieve their goal. Leaders weigh the expected rewards against future costs to calculate the subjective value of continuing.
