I think those are key words, here. When I went to college, I studied architecture, and at the time (the early 70s) the school leaned a lot more toward liberal arts than technology, although theoretically it was part of the Institute of Technology.

I believe the program had a grand total of one (count it, one) major engineering course. There were no courses in drafting, architectural technique, or anything like that. You were expected to "pick this up" by working on your own time for architects.

So I'm sure I ran across more "liberal" professors than your average science student might have. I remember getting reamed out once for suggesting that the free market might result in better phone service. Everyone knew that unless the phones were run as a government-controlled monopoly, nobody would have phone service. After all, who could possibly compete when someone already has a phone line to your house?

At Stanford, I dealt personally with mostly technological professors, and interestingly, many leaned libertarian, rather than conservative. But I spent a lot of time in the environment, and there were leftists aplenty in the vicinity. Stanford isn't even all that much of a "leftist" school.
