File 03 — The Certainty Radius

The Certainty Radius

How far do the consequences of your uncertainty travel?

Answer eight plain questions about a decision and it maps where the decision sits — how much is exposed against how much the truth is being bent to look certain. It lights up how far the harm actually reaches, from you alone out to society, and hands you the six questions to ask before you commit. It does not call anything fraud and it does not call anything safe; it just shows you the structure, including who is being asked to believe you are more certain than you are.

Interactive — the certainty radiusanswer to place the decision

Every decision under uncertainty has two measurements that matter more than the decision itself: how much is exposed, and how much the truth is being bent to make it look certain. Answer eight plain questions. It will not tell you whether to do it. It maps where the decision sits, lights up how far the consequences travel, and hands you the questions to ask before you commit.

01

If this goes wrong, who actually carries the loss?

02

How well can you actually know how this turns out?

03

If you are wrong, how bad is the damage?

04

Can you take it back?

05

Do the people carrying the downside know the risk they are carrying?

06

Are you rewarded for looking more certain than you are?

07

Could someone challenge the optimistic story without being punished?

08

Could an outsider check whether your story is true?

The honest footnote

note This reads the structure of how you described a decision — not the decision itself, and not your situation. It is not legal, financial, or ethical advice. An honest bet can still lose; a high score is not an accusation. The point is narrower: to see how far your uncertainty travels, and who is being asked to believe you are more certain than you are.
