Using the CNI Model to Investigate Individual Differences in Moral Dilemma Judgments

Typical moral dilemmas pitting the consequences of a given action against the action's consistency with moral norms confound several determinants of moral judgments. Dissociating these determinants, the CNI model allows researchers to quantify sensitivity to consequences, sensitivity to norms, and general preference for inaction over action regardless of consequences and norms. However, with the currently available set of dilemmas for research using the CNI model, the model is not suitable for studies with individual-difference designs. To overcome this limitation, the current research investigated the suitability of an extended dilemma battery to make the CNI model amenable for individual-difference research, examining relations of its parameters with psychopathy, empathic concern, need for cognition, self-reported utilitarianism, behavioral activation/inhibition, moral identity, and religiosity. The results support the suitability of the CNI model for individual-difference research with the extended dilemma battery, providing more nuanced insights into the underpinnings of individual differences in moral dilemma judgments.
