Sunk Cost Fallacy

Definition

The sunk cost fallacy is a cognitive bias that leads individuals to continue investing in a decision based on previously incurred costs, rather than evaluating the current and future benefits. This fallacy often results in irrational decision-making as individuals feel compelled to justify past expenditures, which can negatively impact motivation and reward systems. Recognizing this bias is crucial for making rational choices and avoiding further loss.
