The omission effect, first described by Spranca and colleagues, has since been extensively studied and repeatedly confirmed. All else being equal, most people judge it to be morally worse to actively bring about a negative event than to passively allow that event to happen. In this paper, we provide new experimental data that challenges previous studies of the omission effect both methodologically and philosophically. We argue that previous studies have failed to control for the equivalence of rules that are violated (...) by actions and omissions. Once equivalent norms are introduced, our results show that the omission effect is eliminated, even if the negative outcome of the behavior is foreseen and intended by the agent. We show that the omission effect does not constitute a basic, moral disposition but occurs exclusively in complex moral situations. Building on these empirical results, we cast doubt onto two influential explanations of the omission effect, the Causal Relevance Hypothesis and the Overgeneralization Hypothesis, and provide a novel explanation of the phenomenon. Furthermore, we discuss various ramifications of the interplay between our understanding of omissions and legal systems. (shrink)

Legal scholars and philosophers have long debated the moral standing of the act-omission distinction, with some favoring the view that actions ought to be considered as morally different from omissions, while others disagree. Several empirical studies suggest that people judge actions that cause harm as worse than omissions that cause the same harm with the implication that our folk psychology commonly perceives this distinction as morally significant. Here we explore the robustness of people's moral intuitions, and in particular, whether the (...) omission bias can be eliminated in the face of explicit and familiar laws that take away the moral standing of the distinction between actions and omissions. We show that although Dutch law allows both active and passive euthanasia, and although our Dutch participants were well aware of this law and supported it, they nonetheless showed a robust omission bias across a wide range of moral dilemmas. We conclude by discussing the relationship between our folk moral intuitions and explicit moral rules that are handed down by law and religion. (shrink)

This article proposes a way to disambiguate the evaluative states currently identified as “adaptive preferences” in development literature. It provides a brief analysis of Serene Khader's Deliberative Perfectionist Approach, and demonstrates that distinguishing between adaptive states has important implications for the theory and practice of development intervention. Although I support Khader's general approach and consider my project to be complementary, I argue that the term preferences be replaced with four distinct terms: beliefs, choices, desires, and values. Distinguishing among adaptive states (...) can serve to prevent inappropriate intervention and appreciate the costs of transforming inappropriate adaptations. I argue that adaptive values are especially problematic, given how central a person's values are to their sense of meaning and self. Attempts to transform adaptive values are likely to produce internal conflict, resulting in psychological distress and diminished agency. Furthermore, some values preclude deliberation and comparison given their communal status as infinitely valuable. To deliberate about sacred values is to violate them. The emotional and psychological damage that may result from value transformation is thus likely to be extensive, and must be taken into account when determining whether, and what type of, intervention is justified.
