The Evolution of Jealousy

This week, Meghan welcomes evolutionary psychologist Diana Fleischman. Diana’s areas of research include human sexuality, the effect of hormones on behavior, and how “disgust” (the condition of being disgusted) is an evolutionary adaptation, especially for women. In this conversation, Diana talks about why the field of evolutionary psychology is subject to such much bad-faith misapplication but why uncomfortable truths about human mating patterns can nonetheless offer important lessons. She and Meghan explore the relationship between female social hierarchies and cancel culture (for instance, do women control cancel culture?) and then get into a deep discussion about polyamory. What does it really mean? What does it take to make it work? And how come most people just don’t have the emotional discipline to succeed at it.

For the bonus portion for paying subscribers, Diana talks about how her younger self would feel about her current self, why she’s a transhumanist, what’s stopping the world from embracing “clean meat," why she donated her eggs several years ago and wrote letters to her future genetic offspring, and whether she’d pick herself out of a genetic lineup of embryos.
