Haidt & Graham --

Most academic efforts to understand morality and ideology come from theorists who limit the domain of morality to issues related to harm and fairness. For such theorists, conservative beliefs are puzzles requiring non-moral explanations. In contrast, we present moral foundations theory, which broadens the moral domain to match the anthropological literature on morality. We extend the theory by integrating it with a review of the sociological constructs of community, authority, and sacredness, as formulated by Emile Durkheim and others. We present data supporting the theory, which also shows that liberals misunderstand the explicit moral concerns of conservatives more than conservatives misunderstand liberals. We suggest that what liberals see as a non-moral motivation for system justification may be better described as a moral motivation to protect society, groups, and the structures and constraints that are often (though not always) beneficial for individuals. Finally, we outline the possible benefits of a moral foundations perspective for System Justification Theory, including better understandings of 1) why the system-justifying motive is palliative despite some harmful effects, 2) possible evolutionary origins of the motive, and 3) the values and worldviews of conservatives in general.
