"They won't do anything they don't want to do." For example, they would rather die than say things they dont want to say. They would, perhaps, refuse to leave the door open when talking to their students in private so that no one would be able to say that they were piping the grad students (You know? As a form of INSULATION FROM SCANDAL). And they would DEFINITELY not EVER acknowledge someone they didn't want to acknowledge.
Hym "But would 'Disagreeable people' lie blatantly about being Disagreeable? Perhaps.... What would it take for them to lie? Well... Maybe, JUST maybe... "How they might be conceptualized" is higher up on their hierarchy of values than the actual truth. For example, if they engaged in some sort of religious enterprise and you asked them whether or not they believe in God.... They would prioritize how they would be conceptualized for answering over the actual answer. So they wouldn't answer. Why should they? They don't want to. And THEIR will is superordinate to all others and must be preserved at all cost."
