The Behavioral Immune System with Josh Tybur
Podcast: Evolutionary Psychology (the podcast)Published On: Tue Feb 03 2026
Description: 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
