What seems stupid to you is usually reasonable in their reference frame. The example du jour is any type of strongly held belief, whether that be in religion or politics, or whatever else. Someone can hold a fundamental, axiomatic view such that the logical consequences of that view might seem stupid to us, but we don't hold those same axioms.
So, we had manager who systematically misinterpreted what people said. Sometimes with bad intention, other times honestly no understanding and making absurd guesses.
Having to watch the consequences of that, that person was not doing something reasonable from different point of view. It was not about axioms. It was harming everyone including that manager. (That the manager got or kept position is indictment of our company. I am fully aware.)
