Dr. Diana Fleischman has been obsessed with evolution since she was a little girl. Today, she is a leading researcher in the field of evolutionary psychology, a soon-to-be author, and a force in the effective altruism movement. In this interview, Chad and Dr. Fleischman discuss her research, how the EA movement is redefining animal suffering, and how you can minimize your suffering footprint. They also talk about the value of teasing in close relationships and how today’s culture may be going to far to limit healthy humor. This episode is part of our Past, Present, Future theme week.
