One decision, audited adversarially. Fill it in honestly; the goal is to be told no.
-
1 · Spot the system
Did this come from fast intuition, or slow, deliberate analysis? A confident gut call dressed as analysis is the dangerous one.
-
2 · Name the biases
Tick the ones at play — and for each, write the exact thing in your reasoning that shows it. No tick without evidence.
Too much information
Not enough meaning
Need to act fast
What we remember & how we judge what happened
Evidence, in my own words:
-
3 · Apply the outside view
Forget this case. What usually happens in cases like this — the base rate — and how far is your estimate from it?
-
4 · Run a premortem
It's a year later and this decision failed. Write the single most likely reason — concretely.
-
5 · Sit with the hard questions
- If you'd never started / already paid / heard that first number — would you still choose this today?
- What evidence would change your mind, and have you actually gone looking for it?
- Are you choosing this because it's best, or because it's the default / what everyone's doing / what you already want?
- What's the realistic downside — and have you priced it in?
-
6 · Recalibrate
The version of the decision that survives scrutiny (not a reflexive "no") — and a confidence level you can defend.
