How moral perceptions influence intergroup tolerance: Evidence from Lebanon,Morocco,and the United States

Intergroup boundaries are often associated with differences in moral codes. how does the perception of similarity and dissimilarity in moral worldviews influence tolerant relationships between members of different groups? we theorized that the relationship between perceived moral similarity and intergroup tolerance is domain specific. specifically,because people treat autonomy values (e.g.,caring for others,being fair) as denoting universal rights and obligations,but binding values (e.g.,purity) as denoting rights and obligations that apply preferentially for their own group,perceived similarity on autonomy values should be more relevant than perceived similarity on binding values to intergroup tolerance. here,we describe correlational and experimental evidence to support these predictions from studies carried out in lebanon (with sectarian groups),in morocco (with ethnic groups),and in the united states (with ideological groups). implications for understanding intergroup relations and theories of morality are discussed. © 2017 by the society for personality and social psychology,inc.
