This paper calls into question the idea that moral disgust is usefully regarded as a form of genuine disgust. This hypothesis is questionable even if, as some have argued, the spread of moral norms through a community makes use of signaling mechanisms that are central to core disgust. The signaling system is just one part of disgust, and may well be completely separable from it. Moreover, there is plausibly a significant difference between the cognitive scientist’s concept of an emotion and the everyday notion of that emotion. Finally, even if, as this paper contests, some form of disgust were directly elicited by the moral wrongness of certain kinds of behavior, research on the socio-moral elicitors of the disgust mechanism would still be unlikely to shed much direct light on the nature or content of morality.

These results suggest that immorality elicits the same disgust as disease vectors and bad tastes’. This is a conflation of (1) and (2).

Naturalism Without Mirrors (New York: Oxford University Press, 2011), chapters 2, 9 and 12, present the kind of general pragmatist semantic view I favor. Such a view need not deny that ‘water’ refers to H2O, or that it does so in virtue of a story of the sort Saul Kripke tells in Naming and Necessity (Cambridge: Harvard University Press, 1980). But it need not model all reference in the same way.

    Simpson et al., ‘Is Disgust a Homogeneous Emotion?’, p. 39, also highlights some other observable differences: socio-moral disgust intensifies over time, while “core” disgust weakens. Also, general sensitivity to “core” elicitors does not predict sensitivity to socio-moral elicitors.
