Duke and O'Shaughnessy connect decision-making to the Stoic dichotomy: the decision process is inside your control; the outcome is partially outside your control (affected by luck, timing, and information you couldn't have). Judge yourself on the controllable part.

Resulting — judging decision quality by outcome quality — is the most common and most destructive thinking error in business and investing
Duke explains 'resulting': when an investment doubles, we assume the decision was good. When it crashes, we assume the decision was bad. But good decisions can produce bad outcomes (a 90% probability event still fails 10% of the time), and bad decisions can produce good outcomes (lottery winners made terrible expected-value decisions).Was this useful?
