Abstract
Background
Contemporary societies are rife with moral disagreement, resulting in recalcitrant disputes on matters of public policy. In the context of ongoing bioethical controversies, are uncompromising attitudes rooted in beliefs about the nature of moral truth?
Methods
To answer this question, we conducted both exploratory and confirmatory studies, with both a convenience and a nationally representative sample (total N = 1501), investigating the link between people’s beliefs about moral truth (their metaethics) and their beliefs about moral value (their normative ethics).
Results
Across various bioethical issues (e.g., medically-assisted death, vaccine hesitancy, surrogacy, mandatory organ conscription, or genetically modified crops), consequentialist attitudes were associated with weaker beliefs in an objective moral truth. This association was not explained by domain-general reflectivity, theism, personality, normative uncertainty, or subjective knowledge.
Conclusions
We find a robust link between the way people characterize prescriptive disagreements and their sensibility to consequences. In addition, both societal consensus and personal conviction contribute to objectivist beliefs, but these effects appear to be asymmetric, i.e., stronger for opposition than for approval.
From the Discussion
The evidence is now strong that individuals tend to embrace rather diverse metaethical attitudes regarding moral disagreement, depending on the issues at stake (eg. Cova & Ravat 2008; Pölzler & Cole-Wright 2020). Thus, we believe that the time is ripe for empirical bioethics to update this assumption.
