This seems like a jump. Two, actually. First, that academics, who work in a charged political environment and with college students, are sheltered. Second that the majority of humans prefer jerks. I don't know that we can substantiate either of those claims.
It's true that jerks can be in positions of power, but it's hard to say that people prefer them. Indeed, it appears that many people strongly dislike them, but that they are protected by their power and other people with power (a distinct minority).
