Than scientists?
Yes.
Most physicians, accountants, lawyers take a more narrowly focussed curriculum than most scientists. They possibly have, on the average, lower IQs that scientists, but that's mainly a guess.
Sure, there are exceptions.
My experience suggests: Liberal arts and science faculty tend to be liberal, economics faculty tend toward libertarianism, other business school faculty tend to be a little more conservative than the liberal arts faculty but not to the extreme of Republican party of today. I suspect that education college faculty also tend to be a little more conservative than their liberal arts colleagues, but my evidence is very limited on education colleges.
