Invariance Violations and the CNI Model of Moral Judgments

A number of papers have applied the CNI model of moral judgments to investigate deontological and consequentialist response tendencies. A controversy has emerged concerning the methodological assumptions of the CNI model. In this article, we contribute to this debate by extending the CNI paradigm with a skip option. This allows us to test an invariance assumption that the CNI model shares with prominent process-dissociation models in cognitive and social psychology. Like for these models, the present experiments found violations of the invariance assumption for the CNI model. In Experiment 2, we replicate these results and selectively influence the new parameter for the skip option. In addition, structural equation modeling reveals that previous findings for the relationship between gender and the CNI parameters are completely mediated by the association of gender with primary psychopathy.
