Politics in Your Genes

Twin study shows political attitudes are somewhat heritable, more so environmental, but have little to do with upbringing:

To the extent that political ideologies are inherited and not learned, they become more difficult to manipulate. Conservative parents who try to make their children conservative by carefully controlling their children’s environments are probably overestimating the importance of those environments. Offspring of such parents are likely to end up being conservative but less because of the environment created by the parents than the genes passed along by the parents.
