This is interesting:
Intelligent people, however, have a tendency to overapply their analytical and logical reasoning abilities derived from their general intelligence incorrectly to such evolutionarily familiar domains and, as a result, get things wrong. In other words, liberals and other intelligent people lack common sense because their general intelligence overrides it. They think in situations where they are supposed to feel. In evolutionarily familiar domains such as interpersonal relationships, feeling usually leads to correct solutions whereas thinking does not.
