Question

Which logical fallacy occurs when a person continues to pursue a failing course of action simply because they have already invested significant time and money into it?

Accepted Answer

The logical fallacy described is the sunk cost fallacy. This fallacy occurs when an individual makes decisions based on the resources already committed to a course of action rather than focusing on the future utility of continuing that action. A sunk cost is a historical cost that has already been incurred and cannot be recovered, such as money spent on a non-refundable ticket or time spent on a project that is no longer viable. Rational decision-making dictates that sunk costs should be ignored because they are irrecoverable and irrelevant to future outcomes. For example, if a person buys a ticket to a movie but realizes ten minutes into the film that it is poorly made, staying to watch the rest of the movie simply because they paid for the ticket is an example of the sunk cost fallacy. By staying, they lose both the initial money and the additional time, whereas leaving would allow them to reclaim their time for a better purpose.
