Sunk Cost Fallacy: Why We Stick with Bad Decisions

     Consider that you have been working on a project for several months, but it isn't going as you had hoped. It seems like a losing struggle now that you've invested so much time and energy in it. You convince yourself that you've already invested too much to give up, but you persist even though you know it won't go away. This is a typical psychological pitfall known as the "sunk cost fallacy," wherein people continue to make poor judgments based only on past investments.

Psychologically, the sunk cost fallacy is driven by loss aversion—the fear of losing what we’ve already invested outweighs the potential benefits of starting fresh. For instance, think about the last time you stuck with a bad meal at a restaurant because you'd already paid for it. Even though you weren’t enjoying it, you forced yourself to eat more, thinking, "I spent money on this, so I can’t let it go to waste." The truth is, by finishing the meal, you’re not getting any of that money back, but you’re adding discomfort to your experience. This same logic applies to decisions like staying in a dead-end job or continuing a failing relationship—just because you've invested time or effort doesn't mean it’s worth sticking with.

In order to escape this trap, we must change our perspective. Consider this alternative scenario: you spend hours binge-watching a TV show, but after a few episodes, you decide it's not that great. Do you keep watching since you've already invested some time in it? Because giving up feels like a waste of time, many individuals do. Still, pausing frees up time for more pleasurable activities. It's important to consider the rewards you'll receive in the future when deciding whether to stick with it or give up. Letting go of investments from the past that are "sunk" and cannot be retrieved allows you to make better decisions and seize opportunities that will ultimately produce more satisfying results.
