In this episode I chat to Diana Fleischman. Diana is a senior lecturer in evolutionary psychology at the University of Portsmouth. Her research focuses on hormonal influences on behavior, human sexuality, disgust and, recently, the interface of evolutionary psychology and behaviorism. She is a utilitarian, a promoter of effective altruism, and a bivalvegan. We have a long and detailed chat about the evolved psychology of sex and how it may affect the social acceptance and use of sex robots. Along the way we talk about Mills and Boons novels, the connection between sexual stimulation and the brain, and other, no doubt controversial, topics.
