If your search for disconfirming evidence cannot change…
When searching for disconfirming evidence, if your search could not have actually changed your mind, you performed a ritual not genuine disconfirmation—redesign the search until failure is possible.
When This Fires
- You've decided to "consider the other side" before committing to a position
- You're doing due diligence on a decision you've already made emotionally
- Someone asked you to play devil's advocate and you're going through the motions
- You feel good about having "looked at both sides" but your position hasn't budged at all
Common Failure Mode
Searching for disconfirming evidence in the wrong places or at the wrong resolution. You believe your product strategy is correct, so you "look for counter-evidence" by reading industry reports — which are too general to challenge your specific assumptions. Or you ask your team for concerns — but in a meeting format where disagreement has social costs. The search cannot yield disconfirmation because it's structurally incapable of it.
The Protocol
Before searching for disconfirming evidence: (1) Write down: "I would change my mind if I found [specific evidence]." If you can't complete this sentence, you're not ready to search — you need to identify what would count as disconfirmation first. (2) Design your search to go where that specific evidence would live if it existed. (3) After searching, ask: "Did my search have a realistic chance of finding disconfirming evidence if it existed?" If not, redesign and search again.
