Sunk cost fallacy

Definition

The sunk cost fallacy is a cognitive bias that occurs when individuals continue a venture or project due to the resources they have already invested, rather than evaluating the current and future benefits. This fallacy can lead to poor decision-making, as people often irrationally commit to a course of action because they feel the need to justify past investments, despite evidence suggesting that it would be better to cut losses and move on.
