Recommended Read: Tuschman's "Our Political Nature."

I can personally recommend this book, which is subtitled "The Evolutionary Origins of What Divides Us."  The author is an evolutionary anthropologist.  If you are interested in ideology, politics, political polarization, personality and political attitudes, evolution and attitudes/personality, etc.,  this is a book for you.  There are lots of current examples and the book helps make sense of them.  The author is not a biological determinist and also shows how other factors are influential.  However, the author misses some important points about authoritarianism and generally fails to deal with left-wing authoritarianism.  However, there's no need for me to reinvent the wheel, read this review from the Economist.
