Abstract

A recent paper by Tybur and colleagues presents a theory of the evolved functions of disgust based on biological evolution. This work furthers our understanding of disgust and is the first to detail the computational mechanisms involved in detecting and evaluating disgust-related risks. However, because this approach ignores the powerful role of cultural evolution, its ability to encompass the wide and culturally variable range of disgust is limited.
