Most leaders think their job is to resolve uncertainty — to walk into the room with the answer. But Marcus Aurelius, who ran an empire while battling plague and war, spent his private notebooks not consolidating certainty but deliberately dismantling it. What's interesting is that the psychologist James Reason, in his research on organizational accidents, found the same pattern in reverse: high-reliability teams like nuclear plant operators and aircraft crews are trained to treat confidence itself as a warning signal, a state that's statistically correlated with error. Together, these two — a Stoic emperor and an industrial psychologist — point at the same uncomfortable truth: the leader who says 'I've got this figured out' has usually just stopped looking. The practical move today is small. Before your next important decision, name one assumption you haven't questioned. Not to abandon it — just to hold it up to the light for a second.

When did you last change your mind about something in your own domain — and what finally made you do it?
