BW,
I actually do not mind university professors in principle, on the condition that their work and discipline is backed by evidence or experience. That is why I have a lot of esteem for the hard scientists - their study is supported and more importantly useful. But when we enter disciplines like Psychology, it becomes more difficult to say yes or no. Behaviorism, as first practiced by Skinner, was backed by evidence and it managed to develop solutions to behavioral problems like excessive fears (phobias) or in understanding our learning. On the other hand, detractors to Behaviorist Psychology do not bother to use evidence, or it's weak, and they moreover really aren't that helpful. A few good examples are the Humanists and Neo-Freudians.
Then there are the liberal arts. On personal bias, I like some philosophy such as Analytic Philosophy and have a very negative view of Continental Philosophy (continental as in Western Europe with the exclusion of Great Britain where Analytic Philosophy is popular and owes its origins). AP holds that truth can be discovered, aims to write clearly so people can understand, and AP moreover carefully uses logic and evidence to test and support its philosophical conclusions. CP, on the other hand, will write without evidence, use inappropriately advanced and obscure language to sound profound, and labels AP arrogant for giving less than deserved tribute to past great thinkers by testing the truth of what they say instead. Lol, silly Europeans. As for the other disciplines part of the Liberal Arts curriculum in the US (not to bash the classical definition of Liberal Arts), like multicultural studies, post-modernism, women studies, and political science, the focus is really on the normative (what ought to be) rather than how things are and using evidence to support those conclusions. However, there is one school of thought in political science that is both practical and supported by evidence, and that is real politik. But then, most academic circles in the US and Europe bash real politik by calling it immoral and giving it undeserved criticism. Anyhow bw, you should check out real politik, you might like it.
