According to a British scientist, Prof Geraint Rees of University College London, they do. Conservatives have "larger amygdalas, almond shaped areas in the center of the brain often associated with anxiety and emotion, and smaller anterior cingulates, an area at the front of the brain associated with courage and looking on the bright side of life." Very interesting. And liberals have larger anterior cingulates, an area at the front of the brain hence more courage and ability of looking on the bright side of life.
Okay I don’t totally believe in physical basis of liberalism and conservatism. A lot of it is a result of social environment. If a child is born to a conservative family and brought up in a conservative environment then chances are the child will grow up to be a conservative. On the other hand, if the same child is exposed to a lot of liberal educational environment in school, college and university the child may grow up to be a liberal. However, if a child is born to conservative parents and gets no education then he is doomed to be a conservative for rest of his life. Conversely a child born to liberal parents may remain liberal despite lack of education as the child is exposed to liberal environment and liberal values growing up.
