What is status? What is inspiration? What is personality? It all sounds simple and obvious, but in this episode with Patrick Durkee (CSU Fresno), we make "the familiar strange" and think through how an evolved mind may figure out how to invest our time and energy, what inspiration means, and what personality really is.

It stinks to be sick. Our guest, Josh Tybur (VU Amsterdam), is the one of the foremost experts on how our brain--or better yet, our "behavioral immune system"--helps us avoid pathogens while still navigating the necessities of social and physical life: eating, hugging, parenting, mating, and so on. Topics include whether pathogen avoidance actually drives attitudes towards social outgroups, how disgust, sex, and morality all intera...

Intentions be damned! Whats matter is selection! In this episode, Paul Smaldino (UC Merced) takes us on a tour of his work on social signals, social identities, the perverse incentives of science, the stupidity and yet usefulness of models, and so much else. (Paul also shows us his small model of the solar system in the background).

Consciousness: is it really that hard of a problem? In this episode, we talk to our favorite mechanistically-minded (and possibly clearest) thinker about consciousness we've had the pleasure to stumble across, Michael Graziano (Princeton). Topics include why consciousness has been so hard to study, what it is, and what future (evolutionary) work on consciousness would look like.

The evolution of war has occupied science. But what about the evolution of peace? In this episode, we talk to Luke Glowacki about his framing of peace as requiring just as much, if not more, explanation, than the evolution of war, and how it comes about via cultural technology interacting with our evolved psychology. Other topics include the distribution of conflict, the Omo valley research project, and how to think about our own s...

In this episode, we explore all of these questions and more with Sarah Mathew (ASU), who talks about her work with the Turkana, and her long-term interest in the interplay between our evolved psychology of cooperation...
