Most of us learn about sunk cost fallacy in the context of financial investments: the idea that we continue pouring money into something simply because we’ve already spent money on it. However, sunk costs can also be any past investment you can’t recover, such as time, effort, emotional energy, or identity. When we shape decisions based on what we've already invested, rather than what we stand to gain in the future, we limit our ability to adapt.
This bias manifests itself in the systems we continue to use, the clients we retain, how we structure our teams, and how we define our culture. In this fast-paced world, clinging to outdated decisions may be one of the biggest obstacles to flexibility and long-term success.
To recognize where sunk costs shape our choices, we first have to understand why letting go feels so hard.
Why we resist change, even when it’s positive
Our brains prefer predictable routines. Disrupting them requires effort, which is why sticking with an old system or an outdated method can feel easier in the short term, even when it creates friction long term.
We also tend to overvalue things we’ve built ourselves. This phenomenon is known as the IKEA effect, and it manifests in various ways within organizations: the homegrown spreadsheet to which someone is emotionally attached, the process a team created from scratch, or the cultural philosophy that once energized the business.
Most importantly, we often believe motivation precedes action, that we’ll make a change when the timing is right, when inspiration strikes, or when the team is finally “ready.”
However, a lack of movement, whether in personal habits or organizational processes, can create fatigue.
For instance, how does it feel when you stop exercising or fall into poor eating patterns? Your energy dips. Not because you do too much, but because you do less of what fuels you. The same phenomenon plays out inside organizations. The longer teams stay in an inactive state, the heavier the change feels.
Hidden places where sunk cost fallacy affects your business
Legacy systems
Teams continue using outdated tools because switching feels like a major undertaking. People have learned to "work around" the inefficiencies, and the thought of retraining the team or rethinking the workflow is overwhelming. But the cost of sticking with an outdated system exceeds the cost of replacing it.
Hiring decisions
Leaders keep employees who are misaligned with the culture or role because they’ve invested heavily in hiring, training, and onboarding. Even when someone’s performance doesn’t support the organization, leaders hesitate to make changes because it feels like wasting the initial investment, but lost momentum, morale, and performance compound over time.
Client relationships
Some clients require a lot of energy, disrupt workflow, or strain the team. Yet businesses keep them because “they’ve been with us for years.” Longevity becomes justification for tolerating misalignment.
Cultural values and methodologies
Values that once energized the organization can become limiting if never revisited. Cultural norms become habits. Habits become rules. And rules become unquestioned truths, even when they no longer accurately reflect the organization's needs.
Acknowledging these patterns doesn’t mean past decisions were wrong. It simply means the business has evolved, and its structures should evolve with it.
Action = energy, not the other way around
Movement is one of the most reliable antidotes to stagnation. When leaders make incremental adjustments like:
- Refining a process
- Updating a tool
- Inviting new ideas
- Reevaluating long-standing assumptions
They renew energy across the team. People feel a sense of momentum and see improvement is possible. They feel invited into change rather than forced into it.
That momentum doesn’t happen by accident.
Change requires consistent, purposeful action, and action communicates, “We are learning, adapting, and moving forward.” In organizations where leaders model flexibility and curiosity, teams respond with more engagement and creativity, and change becomes a shared effort rather than a top-down mandate.
How to evaluate whether something is truly serving your business
To identify where sunk costs may be influencing your decisions, consider these questions within your leadership team:
- Are you genuinely open to alternatives?
Leaders set the tone. When they demonstrate willingness to challenge their own assumptions, teams feel safer doing the same. - How does your culture respond to new ideas?
Do people feel encouraged to ask, “Is there a better way?” Or do they feel pressure to preserve the status quo? - Are managers equipped to drive innovation?
Managers need training in maintaining systems, but more importantly, they need to be well-versed in evaluating risk, navigating uncertainty, and improving processes. - Are your processes aligned with your current goals?
A simple question often reveals a great deal: “If we were building this today, would we design it in the same way?” - Do your values still activate your team?
Values should evolve as the organization evolves. When they remain static, they risk becoming limiting beliefs.
Letting go is a leadership skill
The sunk cost fallacy is powerful because it hides behind good intentions: commitment, loyalty, tradition, and optimism. But clinging to something simply because you've invested in it is not a sustainable strategy.
If you want an agile, resilient organization that can adapt to a constantly changing world, the first step is asking an honest question: “What are we holding onto simply because we’ve already invested in it?”
The willingness to answer and act on the answer is where meaningful change begins.
