Disgust is an odd thing. It makes sense that we would feel a sense of revulsion at the thought of putting rotten meat in our mouths – that’s pure evolution. But why would we feel the same emotion at the thought of weird sex or from hearing a racist rant?
# Stuff You Should Know: Disgust
Josh and Chuck dive deep into the fascinating science of disgust in this episode, exploring how this universal human emotion evolved from a simple taste reflex into one of the most complex and defining characteristics of being human. They break down the three types of disgust—core disgust triggered by physical contaminants, animal nature disgust that reminds us we're animals, and moral disgust sparked by unfair or unethical behavior—while examining surprising research showing that the same part of our brain lights up whether we're reacting to feces or witnessing injustice. The guys explore wild territory here, acknowledging the gaps in scientific explanations and diving into how disgust varies wildly across cultures, from what foods are acceptable to eat to how societies view different social behaviors, revealing that this supposedly universal emotion is actually shaped by the beliefs and values of where you grow up.
