We conducted a four-part study to map out the conceptual space of a diverse set of immoral items, including those that are extreme and/or intergroup (e.g. child sex abuse, genocide, slavery), with the goal of identifying attributes spontaneously used in moral judgment. In Part 1, we identified 56 immoral items. In Part 2, participants completed a similarity-based card sort task of the 56 immoral items. Multidimensional scaling (MDS) indicated that three-dimensional space was needed to capture the perceived differences among the (...) items. In Part 3, regression analysis indicated that perceived similarity among the immoral items related to their commonness, objectivity, forgivability, and legality. In Part 4, regression analysis indicated that the configuration of immoral items corresponded to the amount of anger and disgust the items elicited and items’ perceived harmfulness. We attempt to synthesize these results and answer questions about the roles of anger, disgust, and harm in moral judgment. (shrink)
