Moral intuitions and political orientation: similarities and differences between South Korea and the United States.

Koreans and Americans were compared in terms of political ideology and moral attitudes. The pattern found among U.S. participants is that liberals rated moral concerns about harm and unfairness higher than Korean conservatives, but conservatives rated moral concerns about betrayals of the ingroup and violations of social hierarchies and physical/spiritual purity higher. Compared with U.S. data (in which concerns about purity and disgust showed the strongest relation to ideology), Korean data revealed higher purity concerns overall, and a weaker relationship between purity concerns and ideology. Results suggested that while the patterns of ideological difference in moral concerns are the same, the magnitude of the differences depends upon the particular histories, traditions, and socioecological factors of these different cultures. They also emphasize a consistent pattern of overall moral structure: liberals discounted concerns related to group cohesiveness (rating them at best "slightly relevant") and rated only individualistic concerns as "somewhat" to "very" relevant, while conservatives rated all moral concerns in the latter range, nearly equating individual and group moral concerns.
