Episode Details

Tonight I sat down with Dr. Mark Defant, a geologist and geochemist whose work on volcanoes and continental crust formation led him into a broader public conversation about science, ideology, gender, and how culture can distort evidence.

We covered his fieldwork from Kamchatka to Central America, why adakites matter to understanding early continental crust, and the pitfalls of centrally planned systems he witnessed in the late Soviet Union. From there, we dug into evolutionary psychology: sexual selection, why men and women tend to want different things in mates, how “patriarchy” can be understood through evolutionary pressures, the pay gap as a story of preferences and trade-offs, and why slogans like “health at any size” conflict with medical evidence. We also talked about the state of academia, DEI policy swings, free speech, and why open inquiry matters more than ever.

I closed with a reminder that science isn’t about pleasing narratives—it’s about testing ideas against data, even when conclusions are uncomfortable. Stay curious, examine claims, and don’t be afraid to ask hard questions; that’s how knowledge moves forward. If you enjoyed this one, share it, leave a comment, and let us know what you want us to cover next.

Resources mentioned: Dr. Defant’s site (markdefant.com), his recent Skeptic magazine piece on interstellar objects, his book “Voyage of Discovery,” evolutionary psychology literature on sexual and natural selection, and classic Twilight Zone episodes referenced (“The Obsolete Man”).
