The influence of decision time on sensitivity for consequences, moral norms, and preferences for inaction: Time, moral judgments, and the CNI model

摘要

It is often discussed that moral judgments are either consistent with the principle of utilitarianism or with the principle of deontology. Utilitarianism is a moral principle stating that the right act is the one that produces the best overall outcome. Deontology represents an ethical position indicating that the morality of an action depends on the intrinsic nature of the action regardless of the consequences. Criticism on the structure of moral dilemmas includes the problem that these dilemmas confound norms and consequences. Recently, a multinomial model (the CNI model) was developed to disentangle and measure sensitivity to consequences (C), sensitivity to moral norms (N), and general preference for inaction versus action (I), respectively. In Experiment 1, we examined the influence of time pressure on moral judgments using the CNI model. We found that time pressure influenced moral dilemma judgments by decreasing participants' sensitivity for consequences. There were no significant effects of time pressure on participants' sensitivity to norms and general preference for inaction. Furthermore, in Experiment 2, we examined the link of reaction times to moral judgments more closely by fitting a hierarchical Bayesian version of the CNI model. Longer reaction times lead to an increase in parameterN, and there was no influence of reaction times on parameterCorI.
