Effects of specialization
Australian National University
It's interesting to compare answers to a question between the whole target faculty population and those who work in the AOS associated with the question. The biggest differences by far, unsurprisingly, concern theism and the philosophy of religion. The next biggest differences are in decision theory (two boxing), philosophy of physical science (B-theory), philosophy of mathematics (Platonism). Then epistemology (invariantism and to a lesser extent internalism), general philosophy of science (Humeanism), social and politlcal philosophy (egalitarianism), metaphysics (non-Humeanism). And smaller differences in many other areas.
Of course those differences could be due to (i) specialists making better-grounded judgments, (ii) selection effects in entering the speciality, (iii) specialists' judgments corrupted by an insider literature, and various other sources. I suspect that most philosophers will agree that each of these sources are at play in some cases, while they'll disagree about which are most at play in which cases!
