## Resource

It stinks to be sick. Our guest, Josh Tybur (VU Amsterdam), is the one of the foremost experts on how our brain--or better yet, our "behavioral immune system"--helps us avoid pathogens while still navigating the necessities of social and physical life: eating, hugging, parenting, mating, and so on. Topics include whether pathogen avoidance actually drives attitudes towards social outgroups, how disgust, sex, and morality all interact (including David's pet theory of kinky sexual practices), and whether evolutionary mismatch is over-used and under-specified (or not). Oh, that whole world-wide pandemic thing. More about Josh Tybur: https://www.joshtybur.com/ https://scholar.google.com/citations?user=Ash8oRMAAAAJ&hl=en
