OVERLAP IN MORALS, FACTS, AND PREFERENCES
2Metaethical judgments refer to judgments about the information expressed by moral claims.Moral objectivists generally believe that moral claims are akin to facts, whereas moral subjectivists generally believe that moral claims are more akin to preferences. Evidence from developmental and social psychology has generally favored an objectivist view; however, this work has typically relied on few examples, and analyses have disallowed statistical generalizations beyond these few stimuli. The present work addresses whether morals are represented as fact-like or preference-like, using behavioral and neuroimaging methods, in combination with statistical techniques that can a) generalize beyond our sample stimuli, and b) test whether particular item features are associated with neural activity. Behaviorally, and contrary to prior work, morals were perceived as more preference-like than fact-like. Neurally, morals and preferences elicited common magnitudes and spatial patterns of activity, particularly within dorsal-medial prefrontal cortex (DMPFC), a critical region for social cognition. This common DMPFC activity for morals and preferences was present across whole-brain conjunctions, and in individually localized functional regions of interest (targeting the Theory of Mind network). By contrast, morals and facts did not elicit any neural activity in common.Follow-up item analyses suggested that the activity elicited in common by morals and preferences was explained by their shared tendency to evoke representations of mental states. We conclude that morals are represented as far more subjective than prior work has suggested. This conclusion is consistent with recent theoretical research, which has argued that morality is fundamentally about regulating social relationships.Keywords: metaethics, morality, social cognition, fMRI, theory of mind
OVERLAP IN MORALS, FACTS, AND PREFERENCES
3Examining overlap in behavioral and neural representations of morals, facts, and preferences.Moral claims (e.g. "eating meat is wrong") can be evaluated on multiple levels. One may agree or disagree with a given claim (a first-order judgment); however, independent of this, one may make a second-order (i.e. metaethical) judgment-regardless of whether you agree or disagree, what information does the claim express? Moral objectivists generally believe that moral claims are either true or false, and that this truthfulness is independent of anyone's personal beliefs (i.e. moral claims are akin to facts). By contrast, moral subjectivists believe that personal beliefs govern whether moral claims are true-or that moral claims cannot be true or false at all (i.e. moral claims are akin to preferences; Sayre-McCord, 1986; for review, see Goodwin & Darley, 2010). Metaethical questions are the subject of intense philosophical debate, yet they are highly relevant to cognitive, social, and moral psychology. Metaethical questions ask how moral information is represented. It is possible that morals are represented...
