This short paper is a commentary on: Chapman, Kim, Susskind, and Anderson (2009), In Bad Taste: Evidence for the Oral Origins of Moral Disgust. Our commentary argues that Chapman et al. have indeed provided useful evidence that disgust is, in its origin, an "oral defense" which has expanded its elicitors so that it now includes many social (moral) elicitors. However, we suggest that Chapman et al. went too far in inferring that all forms of disgust are "the same" just because some of the expressive or other output features of disgust are the same between distaste, core disgust, and moral disgust.
