The differences between liberals and conservatives can run even to the brain
In the study, led by Ryota Kanai of the University College London, people who identified themselves as liberals generally had a larger anterior cingulate cortex — a comma-shaped region near the front of the brain that is involved in decision-making. By contrast, those who identified as conservatives had larger amygdalas — almond-shaped structures that are linked with emotional learning and the processing of fear.
liberals tend to be better at managing conflicting information, while conservatives are though to be better at recognizing threats, researchers said.
Well this definitely makes sense! No wonder liberals are more logical and don't fear change, and conservatives fear things that are different, and can't make rational decisions. :-)
