You buy a piece of clothing. It doesn't quite fit your style, but it was expensive. So it hangs in your closet, unworn, year after year. You can't quite bring yourself to give it away. After all, it's almost new, and you paid a lot for it.
This is the sunk cost fallacy in its mildest form. Harmless, really. Just a shirt taking up space.
But the same psychological pattern shows up in places where the stakes are much higher.
When Sunk Costs Keep Us Stuck
People stay in unfulfilling relationships for years because leaving would mean admitting they wasted all that time. They remain in jobs they hate because changing direction would make the past decade feel pointless. They continue down paths that clearly aren't working because turning back feels like admitting failure.
The longer you stay, the higher the sunk costs climb. And the higher the sunk costs, the harder it becomes to leave. It's a feedback loop that can trap people for years—sometimes for life.
Sunk costs fuel ambivalence about change. They make us weigh past investments more heavily than present reality or future possibility.
The Logic Trap
Here's the uncomfortable truth: the time, money, and effort you've already spent are gone. They're not coming back regardless of what you do next. Staying in a bad situation doesn't recover those investments. It just adds more to the pile.
Rationally, the only relevant question is: "What's the best choice from here forward?" But emotionally, we struggle to let go of what we've already put in.
A Useful Question
If you had never gotten into this situation, would you choose to get into it now?
This question strips away the sunk costs and asks you to evaluate the situation as it actually is. Not as a continuation of past investment, but as a fresh choice.
If the answer is no—if you wouldn't choose this job, this relationship, this path if you were starting fresh—then you're likely being held hostage by sunk costs rather than making a decision aligned with your present values and future wellbeing.
Awareness Creates Options
I'm not suggesting that every difficult situation should be abandoned. Life is complex. There are genuine reasons to persist through hard times.
But when you find yourself unable to make a change that some part of you knows you need, it's worth asking: Am I making this decision based on where I want to go? Or am I just trying to justify where I've already been?
Recognising sunk costs for what they are—past investments that can't be recovered—allows you to make decisions based on present circumstances rather than accumulated history.
That unworn shirt in your closet? Give it away. The life you're living? That deserves at least as much honest assessment.
