Sunk cost fallacy

Definition

The sunk cost fallacy is a cognitive bias that occurs when individuals continue to invest in a decision based on the cumulative prior investment, rather than on the future potential of that decision. This fallacy often leads to irrational decision-making, where people feel compelled to stick with a failing course of action simply because they have already invested time, money, or effort into it. Recognizing this fallacy is essential for making rational choices based on current circumstances and potential outcomes.
