The Sunk Cost Fallacy In Business: Knowing When To Pivot

A project can consume months of work, a substantial budget and the energy of a capable team. Those investments create pressure to keep going, even when the evidence shows that customers are not responding or the commercial model no longer makes sense.

This is the sunk cost fallacy in business: allowing resources already spent to influence decisions about the future. Past expenditure cannot be recovered, yet it often becomes the strongest argument for continuing with a weak product, service or strategy.

The more senior the sponsor, the harder it can be to change direction. A leader may worry about reputational damage, internal politics or the appearance of having made a poor call. In practice, refusing to pivot can turn a manageable setback into a much larger operational and customer experience problem.

Australian organisations face familiar versions of this dilemma, from a digital transformation programme in Sydney to a government contract in Canberra or a new retail concept tested in Melbourne. Clear decision rules help teams avoid throwing good money after bad while still giving promising ideas a fair go.

Why Sunk Costs Distort Business Judgement

A sunk cost is a past expense that cannot be recovered, whether it involves money, time, recruitment, technology or political capital. Rationally, it should have no bearing on the next decision. The relevant question is whether another dollar, hour or meeting will create enough future value.

Human judgement rarely works that cleanly. Loss aversion makes stopping feel like accepting failure, while the endowment effect can make an internally developed product seem more valuable than an equivalent option bought from outside. Escalation of commitment then encourages further investment to justify earlier choices.

The Signals That A Pivot May Be Needed

Warning signs often appear in customer behaviour before they reach financial reports. Trial users may fail to return, employees may create workarounds, or customers may describe the service as useful while declining to pay for it. A high volume of complaints can be informative, but silence and low adoption can be even more revealing.

Look for repeated evidence across channels. In Australia, a concept that performs well in a workshop with inner-city Melbourne professionals may struggle in regional Queensland, where distribution, connectivity and household budgets differ. Segment-level behaviour is more useful than an average result that hides important variation.

Separate Learning From Losing

Stopping a project does not mean the work was worthless. Research may have clarified a customer need, prototypes may have exposed a usability issue, and a failed pilot may have prevented a national rollout. The task is to preserve learning without treating every previous decision as a reason to continue.

Teams should document what has been learned, what remains uncertain and which assets can be reused. This creates a psychologically safer distinction between “the idea did not work as designed” and “the people involved failed”. Nick Naumof’s practice applies behavioural science to these practical decisions across services, products and experiences.

Use A Forward-Looking Decision Rule

Before a major initiative begins, define the conditions that would justify continuing, changing or stopping. These might include repeat usage, conversion, cost to serve, customer satisfaction, operational reliability or a measurable shift in employee behaviour.

A useful review asks: if we were starting today with no previous investment, would we fund this next phase? The answer should be based on expected future returns, opportunity cost and risk. Compare the initiative with credible alternatives, including doing less, partnering, buying an existing solution or redirecting the team.

Make Pivoting Safe For People

Employees often defend a failing project because they fear blame, lost status or redundancy. Senior leaders can reduce this defensive behaviour by rewarding early disclosure of weak signals and making review points routine rather than punitive.

Language matters. “What have we learned?” supports analysis; “Who got this wrong?” invites concealment. In a large organisation, especially one with layers of approval, a small experiment can be a better route to truth than another elaborate business case.

Recommendations For Better Pivot Decisions

Use the following practices to reduce escalation of commitment and improve decision quality:

• Record sunk costs separately from future investment requirements.
• Set measurable continuation and stopping thresholds before launch.
• Review customer behaviour alongside financial and operational data.
• Test the proposition with distinct Australian customer segments.
• Appoint someone to challenge the preferred narrative.
• Hold short, regular decision reviews rather than waiting for annual planning.
• Capture transferable learning when a project is stopped or redirected.

These practices work best when supported by disciplined research rather than intuition alone. Organisations can draw on behavioural insights communities such as the Behavioural Finance and Consumer Insights network to build internal capability, challenge assumptions and improve how evidence is interpreted.

Turn A Failed Bet Into A Better Direction

A pivot is not automatically a retreat. It may mean narrowing the audience, changing the service journey, revising the pricing model, removing an unnecessary feature or moving from a build strategy to a partnership. The right change preserves what has value while releasing the assumptions that no longer hold.

For Australian businesses, this discipline can protect scarce talent, capital and customer trust. Whether the decision concerns a new app, a frontline service, an employee experience programme or a public-sector initiative, the strongest next step is the one supported by future evidence rather than past expenditure.

Bring a behavioural science perspective to the decision before another round of investment is approved. Work with an experienced service design researcher and consultant to identify the real barriers, test viable alternatives and make the pivot practical.
