Royzman and Kurzban suggest that disgust-related facial activity in response to unfairness may reflect a metaphorical communication rather than genuine feelings of disgust. We argue that this is a partial reading of our findings and that our experimental data, and those of others, are inconsistent with a social metaphor interpretation.

Aiming to circumvent metaphor-prone properties of natural language, Chapman, Kim, Susskind, and Anderson (2009) recently reported evidence for morally induced activation of the levator labii region (manifest as an upper lip raise and a nose wrinkle), also implicated in responding to bad tastes and contaminants. Here we point out that the probative value of this type of evidence rests on a particular (and heavily contested) account of facial movements, one which holds them to be “expressions” or automatic read-outs of internal (...) states. We also observe a largely neglected difference between morally induced disgust and moral disgust proper, arguing that data such as Chapman et al.’s (2009) provide evidence only for the former.
