I will say that I think I agree with your dad. My own experience with Ph.D.'s, of which there has been much, has been that they definitely put a LOT of effort into being twits and do a spectacular job (when they are not being nice, reasonable people who just happen to have Ph.D's, like plenty of academics -- in fairness).

I've met many uneducated twits, too, of course, but they don't have the same appallingly condescending pseudo-intelligent swaggering babble that makes for a really, really delightful twit.

IMHO, of course.
