Watch how someone behaves in a deal where they gain zero. That’s their real résumé.

Behavior under incentive tells you very little, since almost anyone performs well when there is something in it for them. The real information sits in situations with no upside: how they treat the server, whether they follow through on what cannot be checked, what they do when walking away would cost nothing. Character lives in those places.

Watch those moments rather than the impressive ones when deciding whom to trust. Notice the same test running on you, because other people are reading it. Do the small unrewarded thing properly, since that is the part they will remember.
