Sunk Cost Fallacy

Definition

The sunk cost fallacy is a cognitive bias that leads individuals to continue investing in a decision based on previously invested resources (time, money, effort), rather than on future value or outcomes. This fallacy often results in people making irrational choices, as they feel compelled to justify past investments instead of evaluating the current situation and potential future benefits.

Review Questions

• How does the sunk cost fallacy influence decision-making processes in both personal and professional contexts?

For example, a person may stay in a failing relationship because they have already invested a significant amount of time and emotions. Similarly, businesses may continue funding unprofitable projects instead of reallocating resources to more promising ventures. This tendency can hinder growth and lead to further losses.

By recognizing this bias, teams can make better choices about where to allocate resources, potentially avoiding continued investment in failing projects. This shift in perspective can promote efficiency and strategic planning, leading to improved overall performance.
