Causality is....well...causality...it's hard to explain. And that's exactly what Tadeg Quillien (Edinburgh) does: figure out what the heck causality is, and how our mind does it. Other topics include domain generality vs. specificity, counterfactuals, relevance, morality, beliefs and theory of mind, and what it means to be computational, and how David Hume was pretty cool.

A guest who needs no introduction. Leda Cosmides (UCSB) talks about how she and John Tooby co-founded the enterprise "evolutionary psychology"---including the how's, when's and why's---and what she thinks about current work. Other topics include why it's good for science to not be a jerk, and how she's come to understand what the heck behavioral and experimental economists are up to.  More about Leda Cosmides: https://psych.ucsb.ed...

Along with Margo Wilson, Martin Daly (McMaster) is one the founding pioneers of evolutionary psychology. In this episode, we get Martin's take on the history and the field. Topics include studying real-world phenomena (like homicide), inequality, and how evolutionary biologists like Williams and Hamilton supported the upstart approach (and whether it's really a different approach at all), and what happens when you give a lab-reared...

Other topics include development, supposedly "over-active" stress responses, rage-bait, chilling out, obesity, parenting, status, teaching history, and much more.

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.

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?

Other topics include the distribution of conflict, the Omo valley research project, and how to think about our own s...
