Behavioral Grooves Podcast

What if your mood, focus, and energy aren’t random—but driven by internal clocks you rarely think about? This week, circadian rhythm expert Daniel Forger explains why jet lag hits so hard, why sleep timing may matter more than sleep duration, and what your wearable data actually means. If you’ve ever questioned your “sleep score” or wondered whether you’re a morning person by design, this conversation will change how you understand your body’s timing system.

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.

You think you know what you want in a partner, but behavioral science says attraction doesn’t work that way. Relationship scientist Paul Eastwick breaks down why dating apps and checklists fail, how attraction actually forms, and why real compatibility grows through interaction, timing, and shared history.
