Study suggests liberals and conservatives have different brain structures
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.
These structural differences, the authors suggest, support previous reports of differences in personality: liberals tend to be better at managing conflicting information, while conservatives are though to be better at recognizing threats, researchers said. "Previously, some psychological traits were known to be predictive of an individual's political orientation," said Kanai in a press release
. "Our study now links such personality traits with specific brain structure."
