I suggest also that intellectuals are just as adept at self-deception.
"What the intellectual craves above all else is to be taken seriously, to be treated as a decisive force in shaping history. He is far more at home in a society that weighs his every word and keeps close watch on his attitudes than in a society that cares not what he says or does. He would rather be persecuted than ignored."
"One of the surprising privileges of intellectuals is that they are free to be scandalously asinine without harming their reputations."
Eric Hoffer
