In the past, having a college education tended to be associated with voting for Republicans; in recent years, however, this correlation has become weaker; in particular, individuals with a postgraduate education — more than a bachlor’s degree — have become increasingly Democratic — as well as liberal. Also, a higher percentage of voters with only a high school education voted Republican in 2000 and in 2004. In essence, as I have told many of my students, the more education one attains — the more liberal one tends to be.
Liberals are generally convinced that they are smarter than conservatives. Indeed, conservatives treat the term “intellectual” with contempt. But, is there any basis to believe that Liberals are right?
A study published in Nature Neuroscience measured brain activity on Liberals and Conservatives and “found” that “the anterior cingulate cortex (AAC) was twice as active in liberals than in conservatives.” AKA, Liberals were more mentally pliable than Conservatives.
I’d be wary of extrapolating this out too far. But, it certainly raises interesting questions about how brains develop, and what effects certain kinds of stimuli (of a Liberal bent?) have on ones cognitive abilities.
