I agree that the fact that (for the most part) education leads to liberalism has more to do with our higher education system than anything else.

In conservative countries like Afganistan, the Taliban (which I believe means "the students" in their language) was started by students and religious teachers. All quite well educated in their own way.

Personally, I agree with Lemur's statements that most of us are more or less the same (moderates), it's the people on the far left and far right that not only seem to be the most irritating, but they also seem to be the same people who AREN'T thinking for themselves and simply spouting off what their favorite radio/television show tells them (Daily Show or Fox News).

The study seems to be rather vague and I'm not sure what the point is other than to tick people off. You might as well do a study to see if blond people hate astronomy. I'm sure you'll see some startling results there too. Purely random, but still something you can make wild generalizations over.
