Sunk Cost Fallacy

Definition

The sunk cost fallacy is a cognitive bias that leads individuals to continue investing in a decision based on prior investments (time, money, or resources) rather than evaluating the current situation objectively. This fallacy often results in irrational decision-making, as individuals may hold onto unproductive ventures simply because they have already committed significant resources, preventing them from cutting their losses and moving on to more beneficial options.
