Surprise! A new study says there are brain differences between conservatives and liberals.
This is going to sound sort of obvious, but here we go: A study from University College London published this week in Current Biology has discovered that there are actually differences in the brains of liberals and conservatives. Specifically, liberals' brains tend to be bigger in the area that deals with processing complex ideas and situations, while conservatives' brains are bigger in the area that processes fear.
According to the report: "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."
