I was reading an interesting article that looked at the differences in brain structure between samples of people who identified themselves as liberal and people who identified as conserative. The study indicates that conservatives have larger amygdalas while liberals have larger anterior cingulate cortexes. The amygdala is involved with memory and processing emotional reactions. This suggest that conservatives are more efficient at processing threats. The anterior cingulate cortex is involved with several autonomic functions, such as regulating blood pressure and heart rate, as well as rational cognitive functions like reward anticipation, decision-making, empathy and emotion. This means that liberals may be more efficient at managing conflicting information Current Biology - Political Orientations Are Correlated with Brain Structure in Young Adults This study says that liberals, on average, have higher IQ's than conservatives: Why Liberals and Atheists Are More Intelligent I can't wait for all of the rants about the supposed "liberal indoctrination" in higher education as a response to this thread.
