Sunk cost fallacy

Definition

The sunk cost fallacy is a cognitive bias where individuals continue investing in a decision or project based on the cumulative prior investment (time, money, resources) rather than the current value or future benefits. This often leads to poor decision-making, as the focus on past costs can overshadow rational evaluation of future outcomes. Understanding this bias is crucial for making effective business decisions that prioritize potential returns over historical investments.
