Liberal professors may be the best example of this phenomena.

Actually, liberal professors seem to gravitate to fields where it's very difficult to demonstrate that they are incompetents.

"Actually, liberal professors seem to gravitate to fields where it's very difficult to demonstrate that they are incompetents."

Not necessarily true. In my experience, the hard sciences (math, physics, chemistry) have as many liberals as the social sciences. Engineering is another matter altogether, however.
