Today, I had the privilege of speaking to one of the most influential psychologists in history, Dr. David Buss.

In this episode, you'll get to hear our guest explain sexual conflicts theory.

You'll hear us debate some of the lines of evidence for why female humans and long-term pair bonds have clandestine affairs, or

alternatively, why married women cheat. We discuss intimate partner violence, both physical and

verbal abuse, and Buss explains that these behaviors, while totally evil, are also perhaps
