I guess I’ll drop in before this spirals off to GD with some anecdotal observations. I’ve known and know several people with Ph.D.s. My father was an anthropology professor, my mother was an archeology lecturer and I grew up with the world of academe around. I’ve worked with several Ph.D.s and I have friends who have achieved that level of education.
I’m thinking of two good friends of mine who are both Ph.D.s (in psychology), one female, one male. The woman is a sharp person, and knows her stuff, or so it appears to me. But she doesn’t know squat about science. Zip physics, math, chemistry, biology (wasn’t there a thread not too long ago addressing the differences between psychologists and psychiatrists?); and, for that matter, history; you don’t need to know that stuff to be a Ph.D. Our discussions over the years have revealed to me that she has essentially no opinions on foreign policy, defense, the budget, taxation, etc. She does care about health, and particularly mental health, care. But she isn’t really given to approaching the how of it all. Abortion is the only issue on which she’ll voice an opinion; on that subject she’s an uneasy (Catholic) pro-choice voter. In the complete absence of concern over other issues, that makes her a liberal. She votes Democrat largely because (almost - hehe) all of her friends and associates do. Sharp cookie, though.
The guy is not even a particularly sharp tack. I don’t mean he’s stupid, just not really a lofty thinker. A diligent fellow, to be sure, he knocked on the door for fourteen years and brought that Ph.D. home. He’s gay, and inclined to stay up to date on gay political issues (forever emailing me 'net petitions and the like), but he’s disinclined to gnaw on geopolitics, taxation, etc. Unsurprisingly, he votes Democrat.
My daddy was a Ph.D., in anthropology. The nature of that field did demand that he attempt to integrate knowledge from disparate fields of study, and I’d say he had a better global perspective than either of the two friends mentioned above. And he was your classic 1950s flaming liberal ivory tower academic (immigrant, to boot). He was a sharp cookie who did try to swallow it whole, and voted Democrat.
One of my better friends holds a Ph.D. in physics. He’s one of those naturally curious folks who is continually scratching at new stuff, and generally does a decent job. His view of the world is much more encompassing than either of my psychologist friends’, and he is unflinchingly conservative (and an immigrant - hmm…is that a factor?). Perhaps a varied background has something to do with it - he spent a good part of his formative years and early adulthood as a tattoo artist in Hong Kong, emmigrated to go to school in Ohio and finally came to the oil patch in Texas.
The point of this long winded meander (the coffee was strong this morning) is that attaining a Ph.D. does not necessarily mean one is generally knowledgable, or even truly sharp, it just means that one has devoted enough effort to grasp a certain field of study to a degree that allows them to contribute to that field. While there are certainly (thankfully) a smattering of global intellects out there, I’m inclined to think that as the body of human knowledge continues to expand, more and more specialization will be demanded in most fields and the end result will be manny more Ph.D.s who don’t know any more about the world as a whole than the average bear.
This makes me wonder if the Conrad Hilton School of Hotel and Restaurant Management has a doctoral program.
I’ll tack on a little something to gnaw on as you ponder your generalizations; for the folks addressed in this thread (and me):
Shrink #1 - “liberal” - devout (though troubled) Catholic
Shrink #2 - “liberal” - non-specific Christian
Daddy-o - “liberal” - atheist
Tattoo artist - “conservative” - devout Christian
Moi - “conservative” - atheist
