I think a lot of people are willing to listen, but there is a some amount of evidence that indicates political leanings may have some basis in biology:
> Studies have found that subjects with right-wing, or conservative in the United States, political views have larger amygdalae and are more prone to feeling disgust. Those with left-wing, or liberal in the United States, political views have larger volume of grey matter in the anterior cingulate cortex and are better at detecting errors in recurring patterns. Conservatives have a stronger sympathetic nervous system response to threatening images and are more likely to interpret ambiguous facial expressions as threatening. In general, conservatives are more likely to report larger social networks, more happiness and better self-esteem than liberals. Liberals are more likely to report greater emotional distress, relationship dissatisfaction and experiential hardship and are more open to experience and tolerate uncertainty and disorder better.

> The book is intended as an objective study of the conceptual metaphors underlying conservative and liberal politics although the closing section is devoted to the author's personal views. Lakoff makes it clear however, that there is no such thing as an Objective study of politics, as politics is based in subjective morality.
