Escalation of Commitment
Escalation of commitment is increasing investment in a faltering plan despite weak prospects for future gains. Studied by Barry Staw in 1976, it describes repeated decisions shaped by sunk costs, personal responsibility, or pressure to defend earlier choices rather than expected benefits.

01You've seen this when…
- in life
Your car breaks down again after two expensive repairs. You authorize a bigger repair to make the earlier ones worthwhile and skip comparing replacement options.
- at work
The product you championed misses its sales target for the third quarter. You ask for a larger marketing budget and postpone the review that could shut it down.
- out in the world
A city launches a shuttle service that attracts few riders. Officials respond by buying more buses before checking why residents aren’t using the existing ones.
02The idea
A disappointing result should prompt a fresh decision. Sometimes it prompts a bigger investment instead: more money, more people, another deadline, a stronger public promise. Each new commitment makes the next retreat harder.
Escalation of commitment is that pattern of doubling down on a troubled course of action. It becomes a thinking trap when the case for the next investment is weak, but defending earlier decisions keeps it alive.
It overlaps with the sunk cost fallacy, but the emphasis differs. Sunk-cost reasoning treats unrecoverable spending as a reason to continue. Escalation describes a sequence of decisions in which commitment grows despite discouraging feedback. Sunk costs and personal responsibility can play a role, as can reputation and pressure to appear consistent. A manager can escalate a plan before much money has been spent, simply because they publicly backed it.
The diagnostic question is forward-looking: would an informed person free from pressure to defend the original decision approve this additional investment? A bad result alone leaves that question open.
03Why it happens
- Your first decision becomes something to defend. Failure of a plan you chose threatens both the project and your judgment. More investment offers another chance to prove that you were right. Research finds that personal responsibility can increase escalation after negative feedback.
- Stopping creates an uncomfortable contradiction. You see yourself as capable, yet your decision has gone badly. One way to relieve this cognitive dissonance is to revise your assessment. Another is to insist the plan only needs more support.
- Ambiguous feedback leaves room for a rescue story. Poor sales could mean a bad product, weak distribution or an unlucky launch. Motivated reasoning makes the explanation that preserves your plan especially attractive.
- Other people reward resolve. Leaders are often praised for consistency and criticized for changing direction. Reporting systems and public promises can make withdrawal costly even before anyone examines the remaining economics.
- Investment strengthens attachment. Effort can make an undertaking feel more valuable through effort justification. As commitment grows, neutral evaluation becomes harder. These influences can reinforce one another, though none makes escalation inevitable.
04A worked example
Consider a fictional software company. A director sponsors a product for small retailers. After spending $600,000, the team runs a pilot. Few customers pay, and interviews reveal that most already have an adequate alternative.
The director requests another $250,000 for advertising. There is no new evidence that advertising will fix the problem, but the proposal emphasizes how much the company has built and how damaging cancellation would look.
What it looks like Giving a promising product enough support to succeed, rather than abandoning it at the first setback.
What’s actually going on The pilot has weakened the business case, yet the requested commitment has increased. The director is treating a threat to the original decision as a reason to spend more. The relevant comparison is between this new $250,000 proposal and the best alternative use of that money. Framing the choice as success versus admitting failure keeps attention on defending the original decision.
What would have helped An independent review of the remaining investment, using updated demand estimates. If uncertainty remains, the team could run a small paid-acquisition test with a fixed budget and a decision threshold. That buys evidence rather than assuming a larger rollout will rescue the product.
05How to spot it
06What to do instead
- Treat the next investment as a new proposal. Estimate its remaining costs and likely benefits, then compare it with the strongest alternative. Use marginal analysis: assess what this extra commitment buys. Keep the whole project’s original promise separate from the case for investing more.
- Separate evidence from rescue stories. Write down what has changed since the last decision. A plausible explanation for failure and evidence that the proposed fix will work are separate things.
- Set review rules before you need them. Agree on what evidence would justify continuing and what would call for changing course or stopping. This precommitment keeps the decision responsive to new information.
- Give someone else authority over the review. An independent reviewer should examine the same evidence and be able to reject further spending. Merely inviting comments leaves the original sponsor in control.
- Preserve your earlier reasoning. A decision journal records assumptions before hindsight makes every setback seem foreseeable and every extension seem planned.
- Make responsible withdrawal acceptable. Reward useful learning and timely correction. If stopping is always treated as career failure, people have strong reasons to hide problems and keep going.
07When it isn’t irrational persistence
Troubled projects sometimes deserve more investment. A trial may uncover a fixable defect. A nearly completed asset may deliver substantial value for a small remaining cost. Negative results can also be noisy, especially when outcomes take time to appear.
Past investment can change today’s options. You may now own equipment or have staff you’ve trained, and your contracts may impose cancellation costs. Assess the effect of those present circumstances on future options, keeping the unrecoverable spending itself separate.
Reputation can also have future value. Breaking a commitment may damage relationships or make later agreements harder. Count those consequences explicitly, separating future costs from concerns about saving face.
The trap isn’t continuing after a setback. It’s continuing without a convincing updated case, while making the commitment larger. A disciplined recovery plan names a mechanism and tests it while preserving a meaningful exit.
08Roots
Barry Staw’s 1976 experiment put participants in charge of a company that existed on paper. They faced a familiar management problem: allocate a research-and-development budget between divisions, then decide what to fund after receiving performance results.
The crucial difference was ownership of the first decision. Some participants made the initial allocation themselves; others inherited an allocation made by someone else. When results were unfavorable, those responsible for the original choice committed more resources than those who had inherited it. The experiment suggested that bad news could strengthen commitment precisely because the decision-maker had something personal to defend.
Staw titled the paper Knee-deep in the big muddy: A study of escalating commitment to a chosen course of action. The muddy image fit the puzzle: taking another step could feel like the way out while leaving you deeper in.
Later research moved beyond individual self-justification to examine project features, social pressure and organizational incentives. Staw and Ha Hoang’s 1995 study of professional basketball found that earlier draft picks received more playing time and survived longer in the NBA, even after accounting for performance and other factors. That observational result showed how an organization’s original investment could remain influential in later resource decisions. Its design left causation unresolved. Escalation became a research program about how individuals and organizations make repeated choices.
09How solid is this?
Experiments and a substantial meta-analytic literature support escalation and several contributing factors, including personal responsibility and sunk costs. Effects depend on context; field studies are harder to interpret because continued investment can also have legitimate forward-looking benefits.
