*"Students who reported more "conservative" political views tended to have larger amygdalae,[6] a structure in the temporal lobes that performs a primary role in the processing and memory of emotions. In addition, they found clusters in which gray matter volume was significantly associated with conservativism in the left insula and the right entorhinal cortex.[6] There is evidence that conservatives are more sensitive to disgust[8] and the insula is involved in the feeling of disgust.[9] On the other hand, more 'liberal' students tended to have a larger volume of grey matter in the anterior cingulate cortex,[6] a structure of the brain associated with monitoring uncertainty and handling conflicting information.[6][7] It is consistent with previous research suggesting that individuals with a larger ACC have a higher capacity to tolerate uncertainty and conflicts, allowing them to accept more liberal views.[10] The authors concluded that, "Although our data do not determine whether these regions play a causal role in the formation of political attitudes, they converge with previous work to suggest a possible link between brain structure and psychological mechanisms that mediate political attitudes.""* - *<https://en.wikipedia.org/wiki/Biology_and_political_orientation>*
