The standard story about founder self-deception is that it's a discipline problem. Smart, rigorous operators don't fall for it. The standard story is wrong. The smartest founders in the room lie to themselves about risk more than the average founder, not less. The rigor is the wrapping, not the antidote.
You'll see why every decision framework, decision trees, Bayesian, scenario planning, fails silently when the operator hasn't done the OS-level work underneath, and the specific practice that inverts the motivated-reasoning circuit before it eats your analysis.
