>[!abstract] >Pathogen avoidance is the set of innate and learned behaviors that organisms use to evade infection from microorganisms like viruses, bacteria, and parasites. In humans, it typically manifests as disgust following some stimulus, such as seeing a cockroach or smelling rotten food. Interestingly, this emotion of disgust is also socially situational: >[!quote] >Several studies support the assumption of lower feelings of disgust when we share a social identity. Mothers, for example, perceive their own baby’s fecal smell as less disgusting than that of someone else’s baby. Likewise, university students rated a sweaty t-shirt with the logo of their own university as less disgusting than one with the logo of another university. Thus, this source effect posits that the feelings of disgust elicited by a person will differ depending on one’s familiarity with that person: strangers will elicit more, familiar people less disgust ([[Taubert et al., 2023]]). >[!related] >- **North** (upstream): — >- **West** (similar): — >- **East** (different): [[Kindchenschema]] >- **South** (downstream): —
