http://www.nytimes.com/2004/08/22/magazine/22IDEA.htmlA few months before retiring from public office in 2002, the House majority leader Dick Armey caused a mini-scandal when he announced during a speech in Florida,
''Liberals are, in my estimation, just not bright people.'' The former economics professor went on to clarify that
liberals were drawn to ''occupations of the heart,'' while conservatives favored ''occupations of the brain,'' like economics or engineering.The odd thing about Armey's statement was that it displayed a fuzzy, unscientific understanding of the brain itself: our most compassionate (or cowardly) feelings are as much a product of the brain as ''rational choice'' economic theory is. They just emanate from a different part of the brain -- most notably, the amygdala, the almond-shaped body that lies below the neocortex, in an older brain region sometimes called the limbic system. Studies of stroke victims, as well as scans of normal brains, have persuasively shown that the amygdala plays a key role in the creation of emotions like fear or empathy.
If amygdala activity is a reliable indication of emotional response, a fascinating possibility opens up: turning Armey's muddled poetry into a testable hypothesis. Do liberals ''think'' with their limbic system more than conservatives do? As it happens, some early research suggests that Armey might have been on to something after all.
As The Times reported not long ago, a team of U.C.L.A. researchers analyzed the neural activity of Republicans and Democrats as they viewed a series of images from campaign ads. And the early data suggested that the most salient predictor of a ''Democrat brain'' was amygdala activity responding to certain images of violence: either the Bush ads that featured shots of a smoldering ground zero or the famous ''Daisy'' ad from Lyndon B. Johnson's 1964 campaign that ends with a mushroom cloud. Such brain activity indicates a kind of gut response, operating below the level of conscious control.

I don't know about you guys, but being described as "not bright" by a fuck-wit like Armey just defies description.
