Sunk cost fallacy

Definition

The sunk cost fallacy is a cognitive bias that occurs when individuals or organizations continue investing in a decision based on the cumulative prior investment (time, money, resources) rather than the future potential benefits. This fallacy often leads to irrational decision-making because past investments should not influence future choices if those investments cannot be recovered.
