SUNK COSTS: The Fallacy

By Staff Reporters



A common term in business, the sunk cost fallacy applies to our choices and activities made daily.


A sunk cost fallacy is a simple logical fallacy that means sticking with a losing or failed venture or activity because you have already invested considerable time, energy, money, or other things you can’t get back. It’s the idea that because you already have incurred costs, you stick with it to  “get your money’s worth.”

The sunk cost fallacy differs from other logical fallacies because it’s not a rhetorical fallacy. You may also experience a discussion with a “red herring” or “straw man” fallacy with someone. But the sunk cost fallacy is an illogical choice as a way to justify to yourself why you keep doing something.
