Interindividual Differences in the Sensitivity for Consequences Moral Norms and Preferences for Inaction: Relating Basic Personality Traits to the CNI Model

摘要

Research on moral decision making usually focuses on two ethical principles: the principle of (= morality of an action is determined by its consequences) and the principle of (= morality of an action is valued according to the adherence to moral norms regardless of the consequences). Criticism on traditional moral dilemma research includes the reproach that consequences and norms are confounded in standard paradigms. As a remedy, a multinomial model (the CNI model) was developed to disentangle and measure sensitivity to consequences ( ), sensitivity to moral norms ( ), and general preference for inaction versus action ( ). In two studies, we examined the link of basic personality traits to moral judgments by fitting a hierarchical Bayesian version of the CNI model. As predicted, high Honesty–Humility was selectively associated with sensitivity for norms, whereas high Emotionality was selectively associated with sensitivity for consequences. However, Conscientiousness was not associated with a preference for inaction.
