Sunk cost vs sunk potential
Why the "sunk cost fallacy" is the wrong frame for abandoned projects. What you're actually losing when you walk away is not the time you've spent, but the potential value of the project. The two framings lead to different decisions.

The two frames
The sunk cost frame says: "I already spent so much time on this project, I should keep going." This is the framing that traps people in failing projects. The rational decision is to ignore the past costs (which can't be recovered either way) and focus on the future: what does it cost to finish, and what value does finishing create?
The sunk potential frame says: "This project could be worth X if completed. Is finishing it the best use of my time, or is there a better project to start?" This is the framing that helps you make a clean decision: either finish, hand off, or archive.
The two framings, compared
Side by side:
| Question | Sunk cost frame | Sunk potential frame |
|---|---|---|
| Should I keep working on this? | Yes, you've already spent so much. | Maybe, but only if the future value justifies the future cost. |
| What am I losing by quitting? | All the time you've already invested. | The future value of the project (potentially zero, potentially huge). |
| Is this a sunk cost decision? | Yes, you're deciding based on past costs. | No, you're deciding based on future value. |
| What's the right frame? | The wrong frame. | The right frame. |
What the sunk potential frame unlocks
When you frame the decision as sunk potential, three options open up that the sunk cost frame hides:
- Complete it yourself if the future value justifies the future cost. The classic answer.
- Hand it off if the future value justifies the cost for someone else. This is the BreakPoint model — the project lives, but you don't have to be the one to finish it.
- Archive it if the future value doesn't justify the cost for anyone. The project ends. The work is real, but it's not the right project for you (or for anyone right now).
The sunk cost frame hides options 2 and 3 — it makes you feel like you have to keep going because of the time you've already spent. The sunk potential frame makes all three options visible. The right answer depends on the project, your time, and your goals.
Frequently asked questions
What's the sunk cost fallacy?
The tendency to continue a project because of past costs, even when continuing is worse than stopping.
What's sunk potential?
The future value an unfinished project could create if completed.
Why is this the right frame for BreakPoint?
It makes the handoff and archive options visible. Sunk cost only shows "keep going."
