I agree. Of all the Ph.D graduates I know (about a dozen or so), I would say all but maybe two of them are some of the most ignorant people I know. They only know what they study, which is a rather narrow track of a particular field. Completely clueless outside of their field, and only slightly coherent within it. They only continued from their Master's onto their Ph.D because they couldn't find a job after getting their masters, so they just stayed in school. They received their Ph.D because they spent the maximum allowed time there doing work and the professor felt bad for them. Or, they gave their professor (i.e. the PI) a blow job or sex (no, not a joke). Half are ivy, half are state schooled, and all but two are dumb as a freakin' rock. I have zero respect for Ph.D's.
