Verbal intelligence is correlated with socially and economically liberal beliefs
Abstract
Research has consistently shown that intelligence is positively correlated with socially liberal beliefs and negatively correlated with religious beliefs. This should lead one to expect that Republicans are less intelligent than Democrats. However, I find that individuals who identify as Republican have slightly higher verbal intelligence than those who identify as Democrat (2–5 IQ points), and that individuals who supported the Republican Party in elections have slightly higher verbal intelligence than those who supported the Democratic Party (2 IQ points).
