Moral inferences from androgynous faces are beyond categorical uncertainty: Evidence of a positive bias towards androgynous targets

Postulating a negative bias towards social ambiguity, we conducted cross-cultural online research to assess whether categorical discrepancies in the perception of androgynous faces were associated with the uncanny feeling and inferences of different morality. Across four studies, we found that androgynous faces were harder to classify into a binary sex category than sex-typical faces, but this difficulty did not influence social judgements of androgynous targets in a negative fashion. In Study 1 (Spanish-speaking sample, N = 76), we found that androgynous faces were rated as more trustworthy, less creepy, and less morally different than sex-typical faces. Study 2 replicated most of the findings from Study 1 in an Italian sample (N = 45). Positive bias towards androgyny was not replicated with a different set of stimuli featuring faces of diverse ethnic backgrounds (Study 3, Spanish-speaking sample, N = 140). However, results revealed a main effect of ethnicity in participants’ responses. When controlling for the effect of morphing procedures in stimuli selection, an overall positive bias towards androgynous targets arose, especially when compared to masculine targets (Study 4, Spanish-speaking sample, N = 85). These findings suggest that, at least in certain conditions, a positive social bias towards androgynous faces may emerge that does not depend on categorical uncertainty and facial attractiveness.
