Research is pointing that social liberals tend to have higher IQ's. It's a very debateable topic, and I'm surprised you would even go there. But here's some information:
Despite their important implications for interpersonal behaviors and relations, cognitive abilities have been largely ignored as explanations of prejudice. We proposed and tested mediation models in which lower cognitive ability predicts greater prejudice, an effect mediated through the endorsement of right-wing ideologies (social conservatism, right-wing authoritarianism) and low levels of contact with out-groups
Here's the abstract for the study:
Bright minds and dark attitudes: lower cognitive ability predicts great prejudice through right-wing ideology and lower intergroup contact
Here's an article on that same study in Discover:
Social conservatives have a lower I.Q.? (probably)
Beezzer, won't you be glad after tomorrow so we can go back to talking about aliens and UFO's?
