Even if we know all relevant descriptive facts about an act, we can still be uncertain about its moral acceptability. Most literature on how to act under such normative uncertainty operates on moral realism, the metaethical view that there are objective moral facts. Lay people largely report anti-realist intuitions, which poses the question of how these intuitions affect their interpretation and handling of normative uncertainty. Results from two quasi-experimental studies (total N = 365) revealed that most people did not interpret (...) normative uncertainty as referring to objective moral facts but rather as uncertainty regarding one’s own view, uncertainty regarding the culturally accepted view or as the result of ambivalence. Especially the anti-realist majority of participants interpreted normative uncertainty different to how it is described in the literature on choice under normative uncertainty. Metaethical views were also associated with lay peoples’ choice of uncertainty reduction strategies and with assumptions about the intended aim of such strategies. The current findings suggest that empirical investigations of normative uncertainty might benefit from considering folk metaethical pluralism, as the lay public largely disagrees with the metaethical assumptions underlying the current discourse on choice under normative uncertainty.

Prior work has established that laypeople do not consistently treat moral questions as being objectively true or as merely true relative to different perspectives. Rather, these metaethical judgments vary dramatically across moral issues and in response to different social influences. We offer a potential explanation by examining how objectivists and relativists are evaluated in different contexts. We provide evidence for a novel account of metaethical judgments as signaling tolerance or intolerance of disagreement. The social implications of signaling tolerance or intolerance (...) in different contexts may motivate different metaethical judgments. Study 1 finds that relativists are perceived as more tolerant, empathic, having superior moral character, and as more desirable as social partners than objectivists. Study 2 replicates these findings with a within-participants design and also shows that objectivists are perceived as more morally serious than relativists. Study 3 examines evaluations of objectivists and relativists regarding concrete moral issues, finding these results vary across situations of moral agreement and disagreement. Study 4 finds that participants' metaethical stances likewise vary when responding in the way they think would make a person who agrees or disagrees with them evaluate them more positively. However, in Study 5, we find no effect on metaethical judgment of telling participants they will be evaluated by a person who agrees or disagrees with them, which suggests either a failure to induce reputational concerns or a more limited influence of reputational considerations on metaethical judgments, despite strong effects on social evaluation.
