Sunk Cost Fallacy: Why Past Expenses Can Hinder Decision-Making

Sunk cost refers to past expenditures that cannot be recovered. In project management, sunk cost involves expenses that have already been incurred and cannot be retrieved, such as investment in equipment, research and development costs, and marketing expenses. Considering sunk costs in decision-making can lead to the sunk cost fallacy, where individuals continue to invest in a project despite its low probability of success due to previous investments. This irrational behavior can result in further losses, emphasizing the importance of making decisions based on objective evaluations rather than past expenditures.
