Experimental philosophers and psychologists investigate whether people perceive moral judgments to be objectively true or false. Existing research focuses on a single dimension of ‘perceived objectivity’. The present research examines whether multiple dimensions of folk moral objectivity underlie moral judgments. It also examines whether such dimensions relate to perceived objectivity, tolerance, and people’s behavioral intentions to punish norm-violators. Exploratory factor analysis on twenty ethical items revealed three different ways of perceiving moral truth (Independent Truth, Universal Truth, Divine Truth), which each form reliable subscales (Study 1). This three-factor structure was supported by confirmatory factor analysis (Study 2). Each of the dimensions is differently related to perceived objectivity (Study 3). With respect to tolerance, perceived objectivity is a mediator in the relationship between perceiving moral truth as absolute or universal and tolerance (Study 4). With respect to a willingness to harm measure, Independent Truth is negatively related and Universal Truth is positively related, to people’s punitive attitudes toward norm-violators.

A prevalent assumption in metaethics is that people believe in moral objectivity. If this assumption were true then people should believe in the possibility of objective moral progress, objective moral knowledge, and objective moral error. We developed surveys to investigate whether these predictions hold. Our results suggest that, neither abstractly nor concretely, people dominantly believe in the possibility of objective moral progress, knowledge and error. They attribute less objectivity to these phenomena than in the case of science and no more, or only slightly more, than in the cases of social conventions and personal preferences. This finding was obtained for a regular sample as well as for a sample of people who are particularly likely to be reflective and informed (philosophers and philosophy students). Our paper hence contributes to recent empirical challenges to the thesis that people believe in moral objectivity.

In this paper I argue that there are at least two ways in which people can be moral objectivists, namely implicitly and explicitly. It is possible to explicitly deny being a moral objectivist while being implicitly committed to it. (Enoch, Shafer and Landau (eds), The Ethical Life: Fundamental Readings in Ethics and Moral Problems, 192–205, Oxford University Press, New York, 2014) presents three thought experiments to convince his reader that they are moral objectivists even if they explicitly think otherwise. As it happens, Enoch’s tests, which he uses as intuition pumps, provide excellent measures of implicit metaethical commitments. In this paper I use each of them as material for survey experiments to test whether people are implicit moral objectivists. Overall, results provide support for the idea that people are moral objectivists.
