>Disagreeable personalities are definitely a thing, and some have some other stuff stacked on top that can make for persistently unreasonable people. I score in the bottom 3rd percentile for trait agreeableness. I'm mostly polite unless perhaps I know something is not right and someone is trying to pull a fast one. I can totally see how low agreeableness combined with being towards the lower end of the distribution on intelligence would make a default strategy of loudly saying your piece and being too dense to a) know you shouldn't do that, b) consider your lack of understanding might be the root of the problem and c) comprehend the implications of what you're being told so that you can calm the heck down. I really feel for those people.
