I have just put online the last article I ever had published in a learned journal. It was published in 2004 but I had lost my copy of it. But I recently did a big clean-out of my library and found then that which was lost. It is Ray, J.J. (2004) "Explaining the Left/Right divide". Social science and modern society. 41(4), 70-78 .
The first half of the article does a brief survey of the last 1500 years of history and shows that a concern for individual liberty and a distrust of government has always been central to conservatism.
The second half looks at the various theories about the psychological underpinnings of conservatism. I think all the theories discussed there do reduce to my more recent formulation that conservatives are the dispositionally contented people. For more on that formulation, see here, here and here
