In the real world - and even more so in a super privacy-conscious version of the real world - nobody has perfect information about how the other person acts towards others. Politicians renege on public commitments and racists hire minorities to bully all the time.

Suppose you have a hiring manager that expresses racist views about minority engineers but then tells you not to tell anyone. Why on earth should their plea for secrecy and some nonwhite faces in the office lead you to assume that they're scrupulously fair in their decision making?
