People’s beliefs about normality play an important role in many aspects of cognition and life (e.g., causal cognition, linguistic semantics, cooperative behavior). But how do people determine what sorts of things are normal in the first place? Past research has studied both people’s representations of statistical norms (e.g., the average) and their representations of prescriptive norms (e.g., the ideal). Four studies suggest that people’s notion of normality incorporates both of these types of norms. In particular, people’s representations of what is (...) normal were found to be influenced both by what they believed to be descriptively average and by what they believed to be prescriptively ideal. This is shown across three domains: people’s use of the word ‘‘normal” (Study 1), their use of gradable adjectives (Study 2), and their judgments of concept prototypicality (Study 3). A final study investigated the learning of normality for a novel category, showing that people actively combine statistical and prescriptive information they have learned into an undifferentiated notion of what is normal (Study 4). Taken together, these findings may help to explain how moral norms impact the acquisition of normality and, conversely, how normality impacts the acquisition of moral norms. (shrink)

Tyler conducted a longitudinal study of 1,575 Chicago inhabitants to determine why people obey the law. His findings show that the law is obeyed primarily because people believe in respecting legitimate authority, not because they fear punishment. The author concludes that lawmakers and law enforcers would do much better to make legal systems worthy of respect than to try to instill fear of punishment.

People disagree about whether “moral facts” are objective facts like mathematical truths (moral realism) or simply products of the human mind (moral antirealism). What is the impact of different meta-ethical views on actual behavior? In Experiment 1, a street canvasser, soliciting donations for a charitable organization dedicated to helping impoverished children, primed passersby with realism or antirealism. Participants primed with realism were twice as likely to be donors, compared to control participants and participants primed with antirealism. In Experiment 2, online (...) participants primed with realism as opposed to antirealism reported being willing to donate more money to a charity of their choice. Considering the existence of non-negotiable moral facts may have raised the stakes and motivated participants to behave better. These results therefore reveal the impact of meta-ethics on everyday decision-making: priming a belief in moral realism improved moral behavior. (shrink)

Moral judgment constitutes an important aspect of adults’ social interactions. How do adults’ moral judgments develop? We discuss work from cognitive and social psychology on adults’ moral judgment, and we review developmental research to illuminate its origins. Work in these fields shows that adults make nuanced moral judgments based on a number of factors, including harm aversion, and that the origins of such judgments lie early in development. We begin by reviewing evidence showing that distress signals can cue moral judgments (...) but are not necessary for moral judgment to occur. Next, we discuss findings demonstrating that both children and adults distinguish moral violations from violations of social norms, and we highlight the influence of both moral rules and social norms on moral judgment. We also discuss the influence of actors’ intentions on moral judgment. Finally, we offer some closing thoughts on potential similarities between moral cognition and reasoning about other ideologies.
