Domains of disgust

Tybur, et al., outlines three domains of disgust: pathogen disgust, which "motivates the avoidance of infectious microorganisms"; sexual disgust, "which motivates the avoidance of sexual partners and behaviors"; and moral disgust, which motivates people to avoid breaking social norms. Disgust may have an important role in certain forms of morality.

Pathogen disgust arises from a desire to survive and, ultimately, a fear of death. He compares it to a "behavioral immune system" that is the 'first line of defense' against potentially deadly agents such as dead bodies, rotting food, and vomit.

Sexual disgust arises from a desire to avoid "biologically costly mates" and a consideration of the consequences of certain reproductive choices. The two primary considerations are intrinsic quality (e.g., body symmetry, facial attractiveness, etc.) and genetic compatibility (e.g., avoidance of inbreeding such as the incest taboo).

Moral disgust "pertains to social transgressions" and may include behaviors such as lying, theft, murder, and rape. Unlike the other two domains, moral disgust "motivates avoidance of social relationships with norm-violating individuals" because those relationships threaten group cohesion.
