Jonathan Haidt turns his attention from understanding liberal and conservative intuitions about morality toward understanding libertarian morality — and what he and his colleagues conclude is not exactly earth-shattering:
We found that, compared to liberals and conservatives, libertarians show 1) stronger endorsement of individual liberty as their foremost guiding principle and correspondingly weaker endorsement of other moral principles, 2) a relatively cerebral as opposed to emotional intellectual style, and 3) lower interdependence and social relatedness. Our findings add to a growing recognition of the role of psychological predispositions in the organization of political attitudes.
