Sunk Cost Fallacy

What It Looks Like:

The tendency to continue investing in a failing course of action because of previously invested resources (time, money, effort), even when it no longer makes sense.

Sarah, a senior manager, continues to invest time and resources into a failing project because of the significant amount already spent, despite clear signs that it’s no longer viable. Her attachment to past investments causes her to overlook more promising opportunities, resulting in wasted resources and missed chances for success.

What if overcoming the sunk cost fallacy isn’t just about letting go, but about how you focus on future potential and make decisions based on the best path forward, rather than past investments?

After Implementing Behavioral Insights:

Sarah learns to recognize when past investments should no longer influence her decisions. She develops the ability to assess situations with a forward-thinking mindset, focusing on the potential future value rather than past costs. In her next decision, she halts the failing project and redirects resources toward more promising opportunities, helping the team shift focus and move forward with confidence.

Business Impact:

  • Improved decision-making by focusing on future potential.
  • Increased team efficiency and resource optimization.
  • Enhanced organizational adaptability by learning from past mistakes and pivoting when necessary.

Characteristics:

  • Refusing to shut down failing projects due to past investments.
  • Continuing bad hires instead of restructuring teams.
  • Resisting process improvements because of past infrastructure spending.
  • Defending poor strategic decisions instead of pivoting.

Contributing Factors (Causes):

  • Fear of admitting failure: Ego & reputational risk.

Triggers:

  • Public commitment to an initiative: Makes reversal seem like failure.
  • Fear of stakeholder backlash.

  • Use Data, Not Emotion: Regularly assess ROI & opportunity costs.
  • Normalize Reversals: Highlight companies that have pivoted successfully.
  • Separate Decision-Makers: Have fresh leadership assess troubled projects objectively.
  • Encourage Agile Thinking: Reward teams for adapting vs. persisting blindly.

Business Outcomes (KPIs):

  • Increase in Project Termination Efficiency: Faster course corrections.

By addressing this bias, leaders like Sarah can improve resource allocation, enhance team morale, and foster an agile, forward-thinking organizational culture.
