What is the difference between a modern American social science or humanities professor and a fool?

The fool knows he's full of it while the academic actually believes the drivel he writes.  Here'e the latest joke from our tenured twits:

Good news: A new “groundbreaking” research project has found that conservative brains are structured to be “fearful” and “reflexive,” while liberal brains are structured to be “courageous” and “optimistic.” Over at the New York Post, Kyle Smith discovers that this important study has cleared up some confusing discrepancies in his own life: “[Professor] Rees has the answer to why, in my Army career, I kept running into so many conceptual performance artists from San Francisco and Chelsea. Seldom did I do a push-up or clean my M16 without finding myself amid heated debate from the officer class about whether Walter Mondale or Eugene McCarthy was the most inspiring American political leader of our era.”
