What truly helps people live longer, healthier lives? In this episode, we talk with journalist and author Ken Stern about the science behind longevity and why social connection may matter more than diet or exercise alone. From loneliness being compared to smoking 15 cigarettes a day to cultures that keep older adults engaged through work and community, we explore how purpose, relationships, and social structures shape healthy aging.

Innovation does not always come from inventing something entirely new. Often, the natural world has already solved the problem. In this throwback conversation, we explore the concept of biomimicry with behavioral scientist Sam Tatam, author of Evolutionary Ideas: Unlocking Ancient Innovation to Solve Tomorrow’s Challenges. We discuss how looking to nature can inspire creative solutions in behavioral science and beyond, from the principles of biomimicry to frameworks like the Theory of Inventive Problem Solving (TRIZ) and the Goal Gradient theory. Along the way, we also wander into lighter territory, chatting about the musical artist Sam once traveled to Italy with and the cultural differences between pubs in London and Sydney.

In this special Grooving session, we unpack what happens when shared facts collapse and preferred beliefs take their place. Sparked by Kurt's firsthand experience during unrest in Minneapolis, this conversation explores why people reject lived experience, how identity defense and motivated reasoning shut down dialogue, and when it’s rational to stop trying to persuade altogether. Drawing on behavioral science, persuasion research, and real-world encounters, we examine how to choose your battles, why stories succeed where arguments fail, and what it actually takes to find common ground in a belief-first world.

Dating in 2026 feels broken. The apps promise infinite choice, rom-coms on our screens promise “the one”, and yet frustration, ghosting, and mismatched expectations seem to be more normal than anything actually working out. This week, Tim Ash, author of Primal Dating, joins us as we explore why dating in the modern world feels so unstable and why many of today’s relationship struggles aren’t personal failures, but predictable outcomes of our ancient instincts clashing with modern environments and expectations.
