Conservatives uses the amygdala which is active in social learning and threat detection and handling and therefore are more social orinetd. Because every society has it won codes, conservative may tend to be more local-culuter oriented, and when they will engage different cultures and especialy very different cultures, they will be more un-knowing and therefore will feel more threathend. In General they feel more threat, and may prefer war over peace, because they feel less pain when evaluating the consequence.

Liberals are more intelligent and will try to solve social and non-social conflicts by thinking. They will avoid risks due to more sensitivity to pain and lost.
