Well, I don't have any judgment on that. My point is more basic: generally speaking, conservatives think, and liberals feeeeeeeeeeeel.
A difference in quality of policies generally results.
True, and I'm sure that more math profs would be politically conservative than artsy types; but in turn, more engineering profs would be politically conservative than the pure math or physics guys... because in engineering, it actually *matters* whether you're right or not. We don't live in a perfect, frictionless world, and engineers have to be aware of that. Similarly, public policy does not take place in a perfect world of the best intentions and common interests -- human nature & self-interest introduce other variables.
