Sunk cost fallacy

Definition

The sunk cost fallacy is a cognitive bias where individuals continue an endeavor or commitment based on previously invested resources (time, money, effort) rather than current and future benefits. This often leads to irrational decision-making, as people feel the need to justify past investments instead of evaluating the situation afresh. It highlights how emotions can cloud judgment and obstruct effective choices.
