Bertram Gawronski and Jennifer S. Beer Department of Psychology, University of Texas at Austin, Austin, TX, USA ABSTRACT ARTICLE HISTORY The distinction between utilitarianism and deontology has become a prevailing framework for Received 6 July 2016 conceptualizing moral judgment. According to the principle of utilitarianism, the morality of an Revised 7 October 2016 action depends on its outcomes. In contrast, the principle of deontology states that the morality Published online 28 October 2016 of an action depends on its consistency with moral norms. To identify the processes underlying utilitarian and deontological judgments, research in psychology and neuroscience has investi- KEYWORDS gated responses to moral dilemmas that pit one principle against the other (e.g., trolley Deontology; measurement; dilemma). However, the interpretation of responses in this paradigm is ambiguous, because moral judgment; omission the defining aspects of utilitarianism and deontology, outcomes and norms, are not manipulated. bias; utilitarianism We illustrate how this shortcoming distorts interpretations of empirical findings and describe an alternative approach that overcomes the limitations of the traditional paradigm.

This rationalist approach has recently whereas deontological judgments are the product of given way to theories that attribute a fundamental role automatic emotional processes that do not necessarily to affective and intuitive processes in moral judgment involve a reasoned application of moral norms (Greene, (Greene & Haidt, 2002). Consistent with the latter idea, Nystrom, Engell, Darley, & Cohen, 2004; Greene, several recent theories argue that moral judgments Sommerville, Nystrom, Darley, & Cohen, 2001).

In the latter case, it measured with scenarios that pit one principle against the would be ill-founded to call the observed responses other.

Thus, acceptance of harmful action because they are in conflict with the moral norm that one in trolley dilemmas (and structurally similar dilemmas) should not kill other people (i.e., it is unacceptable to kill may reflect either (A) a genuine sensitivity to outcomes another person, regardless of the outcome). Thus, partici- or (B) a general willingness to accept harmful actions pants who view these actions as acceptable are usually independent of their outcomes.
