Reputation depends partly on what people expect you to do when nobody can check.

Reputation is really a forecast of your unobserved behavior. People have decided what they think you do when there is no audit, no witness, and no consequence, and that estimate is the thing that determines how much is entrusted to you. It is built from small tells over years, and it is more accurate than most people realize.

Pay attention to the situations where nobody could check. Those are the ones actually forming the estimate, in you and in how others read you. Behaving the same way unobserved is not just integrity; it is what makes the reputation real.
