Introduction
Sunk-cost framing is one of the most powerful ways that decisions become trapped. Once substantial time, money, effort or reputation has been invested, abandoning a project often feels like admitting failure. The psychological mistake is subtle: past, unrecoverable costs become treated as a reason to spend even more future resources, even though those past costs cannot be changed. Rationally, only future costs, future benefits and realistic alternatives should determine what happens next. Yet the emotional baseline shifts. Instead of asking, “Is this still the best use of our resources?”, people begin asking, “How can we justify everything we’ve already spent?” Research in behavioural decision-making consistently shows that this shift encourages escalation of commitment, particularly when projects encounter setbacks rather than clear success.

Why past investment changes the emotional baseline
Sunk costs are investments that cannot be recovered. They include obvious financial spending but also months of work, years of education, emotional effort, political capital and public promises. None of these should influence whether additional investment is worthwhile. However, people rarely experience them as psychologically neutral.
Instead, previous investment changes the reference point from which future decisions are judged. Stopping no longer feels like choosing between two future paths. It feels like accepting a definite loss. Continuing, by contrast, preserves hope that the earlier investment might eventually be justified. This is one reason sunk-cost framing often becomes intertwined with the loss-focused thinking described by prospect theory: people become willing to accept larger future risks in order to avoid recognising an existing loss.

The classic experiments by Hal Arkes and Catherine Blumer demonstrated that people become more likely to continue an activity after making larger prior investments, even when those investments are irrelevant to the current decision. Their theatre-ticket field study, for example, found that customers who had paid more for season tickets attended more performances despite identical future enjoyment, suggesting that people try to avoid “wasting” previous expenditure rather than maximising future value.

The emotional shift is important because the decision frame quietly changes:
- Forward-looking frame: “What option creates the best outcome from today onward?” [sunk]dictionary.cambridge.orgEnglish meaning - Cambridge Dictionary7 days ago — Meaning of sunk in English… experiencing serious trouble, or unable to solve a pr… Sunk-cost frame:** “How do we avoid wasting everything already invested?”
Those questions appear similar but produce systematically different choices.
How escalation of commitment appears in projects
Escalation of commitment occurs when decision-makers continue investing in a failing course of action despite mounting evidence that changing direction would produce better outcomes. Barry Staw’s pioneering organisational research identified this pattern decades ago, and later reviews have shown that it appears across business, government, engineering and personal decisions. [Wikipedia]WikipediaEscalation of commitmentEscalation of commitment
Several reinforcing mechanisms make escalation particularly difficult to recognise while it is happening.
Each new investment increases the pressure to justify previous ones. After spending £1 million on a troubled software project, another £100,000 may appear relatively small compared with admitting the original investment produced little value.
Responsibility becomes personal. Managers who approved the initial decision often experience withdrawal as an admission of poor judgement. Continuing allows them to preserve consistency, at least temporarily, even if objective evidence has deteriorated. Research identifies self-justification as an important contributor to escalation in organisational settings. [Wikipedia]WikipediaEscalation of commitmentEscalation of commitment
Hope competes with evidence. Once substantial resources have been committed, even weak positive signals receive disproportionate attention. A minor improvement becomes interpreted as proof that recovery has begun, while warning signs are discounted.
Near-completion becomes emotionally compelling. Projects approaching an apparent finish line often receive additional funding because abandoning them feels especially wasteful. Yet the amount already completed says little about whether the remaining investment will create sufficient future value.
Large infrastructure projects provide familiar illustrations. The term “Concorde fallacy” emerged because governments continued supporting the supersonic aircraft programme long after its commercial prospects had deteriorated, with previous investment becoming part of the justification for continued expenditure rather than remaining irrelevant to future decisions. While many complex projects continue for multiple reasons, sunk-cost thinking has become one of the defining explanations for this pattern.

Why time and effort can be even more persuasive than money
People often assume sunk costs are mainly financial. Research suggests otherwise.
Time, effort and personal identity frequently create even stronger commitment because they become intertwined with how people evaluate themselves. Leaving a long-term career path, ending an unproductive research project or abandoning years of training may feel like declaring those years meaningless, even when changing direction would improve future outcomes.
Recent research also suggests that social expectations strengthen this effect. People become more willing to continue investing when they believe others expect persistence or when continuing appears socially normal. This means escalation is not driven solely by individual psychology; organisational culture and perceived norms can reinforce it as well.

This helps explain why teams sometimes persist collectively even when many individuals privately doubt the project’s value. Each person assumes that stopping would require explaining both the previous investment and the decision to colleagues, managers or stakeholders.
Reframes that separate past costs from future value
The most effective countermeasure is not pretending sunk costs never happened. They matter for learning, accountability and understanding why the situation arose. They simply should not determine whether additional investment is worthwhile.
Several practical reframes help restore forward-looking judgement.
Ask the restart question. Instead of asking whether to continue, ask: If this project did not already exist, would we choose to begin it today using the resources still required? If the answer is no, previous investment may be driving the decision more than future value.
Separate evaluation from responsibility. A decision to stop does not necessarily imply the original decision was irrational. Circumstances change. New information becomes available. Markets evolve. Evaluating today’s choice independently reduces pressure for self-justification.
Treat previous costs as tuition, not targets. Money or effort already spent may generate useful experience even if the project itself should end. Recovering lessons is often more realistic than recovering the investment.
Compare with alternative uses of resources. Every additional month or budget allocation has an opportunity cost. Asking what else those resources could achieve shifts attention back to future returns instead of historical expenditure.
Invite independent review. People who were not involved in the original commitment are less likely to experience reputational pressure or emotional attachment, making them more willing to judge projects on expected future outcomes rather than past investments. Research on de-escalation strategies suggests reducing self-justification pressures can improve decision quality.

The question that breaks the sunk-cost frame
One question captures the essential reframe:
Would I choose this course of action if none of the previous money, time or effort had already been spent?
If the honest answer is no, then continuing requires a separate justification based on future value rather than past sacrifice.
This question does not guarantee the correct decision. Some struggling projects genuinely deserve continued investment because their expected future benefits still exceed their remaining costs. The crucial distinction is that the decision should be based on those future expectations alone. Once past investment becomes the main reason for continuing, sunk-cost framing has transformed persistence from a potentially rational commitment into an escalating one.
