Why we sit through bad movies, stay in dead-end projects and keep paying for things we don't use. And the one question that gets you out.
Owlthat's you
Penguina friend
A bad movie
1
Owl paid $15 for a movie. Twenty minutes in, it's awful. Owl stays put anyway: "I already paid for it."
What's really going on
2
But the $15 is gone whether Owl stays or leaves. Money, time or effort you can't get back is a sunk cost.
3
So the real choice is only about what comes next: two more dull hours inside, or the evening outside.
4
The test: "If I hadn't already paid, would I choose this today?" If the answer is no, the past shouldn't keep you there.
5
Owl walks out and meets a friend. Same $15 lost, much better evening.
6
The same trap scales up. A project that isn't working gets more time and money because so much went in already.
7
Owl stops stacking the crooked tower and starts something solid. Past effort isn't a reason to keep going.
So, what is the sunk cost fallacy?
Letting money, time or effort you can't get back push you into a choice about the future. Spent is spent. Decide on what's ahead.
Only compare what's ahead
Draw a line at today. Everything to the left of it is gone, whatever you choose. Compare only the options on the right: what each one will still cost you, and what each one will give you.
Three traps
The thoughts that keep us stuck, and one that goes too far the other way.
"I've come too far to quit." Halfway up the wrong mountain is still the wrong mountain."Quitting means it was all wasted." It was spent either way. Staying only adds more."So I should always quit?" No. Keep going when what's ahead is worth it, and count real exit costs, like fees or contracts.
Try the friend test. Imagine a friend in exactly your spot. What would you tell them to do next? It's much easier to ignore someone else's sunk cost than your own.
