AFP: Brain structure differs in liberals, conservatives: study
Curious.WASHINGTON — Everyone knows that liberals and conservatives butt heads when it comes to world views, but scientists have now shown that their brains are actually built differently.
Liberals have more gray matter in a part of the brain associated with understanding complexity, while the conservative brain is bigger in the section related to processing fear, said the study on Thursday in Current Biology.
"We found that greater liberalism was associated with increased gray matter volume in the anterior cingulate cortex, whereas greater conservatism was associated with increased volume of the right amygdala," the study said.
Other research has shown greater brain activity in those areas, according to which political views a person holds, but this is the first study to show a physical difference in size in the same regions.
