Executive coach and author Muriel Wilkins joins us to unpack the invisible beliefs that quietly shape how we lead. We explore why curiosity is the starting point for self-awareness, the common internal blockers she sees in leaders, and why leadership growth is less about changing who you are and more about expanding your mindset. Muriel breaks down how hidden scripts formed early in life can limit our impact later on, and how shifting our beliefs can help us move from stress and suffering to clarity, range, and ease at work. Topics [0:00] Introduction and speed round with Muriel Wilkins [9:33] Are limiting beliefs protective?

In this special episode inspired by questions from our Facebook Community, we explore why big change feels intimidating even though most transformation happens quietly in our daily lives. Kurt and Tim dig into the micro-shifts we overlook, the powerful role expectations play in shaping our confidence and identity, and why surrounding yourself with people who expand your sense of possibility truly matters. They also revisit classic and modern goal-setting research — from Kurt Lewin’s “levels of aspiration” to today’s best evidence — to show how balancing past performance with future dreams helps you find the motivating sweet spot that keeps you moving forward. A Note From Our Team: This show exists because of the community around it — the questions you ask, the curiosity you bring, and the support you’ve given us.

Is violence caused by “bad people,” too many guns, or something deeper? In this episode, University of Chicago researcher Jens Ludwig reveals why most violent acts stem not from evil intent but from ordinary people in unforgiving situations. We explore how behavior, context, metacognition, and split-second decision-making shape violent outcomes — and why small, scalable interventions like pocket parks, foot traffic, and reflective thinking can dramatically reduce harm. If you care about safer communities, more innovative policymaking, or just want to understand human behavior better, our conversation with Jens will forever reshape how you view violence.

Why does gratitude feel so easy to feel yet so hard to say? In this Thanksgiving grooving session, we unpack the psychology behind our awkwardness around expressing appreciation—from miscaliberated assumptions to the belief that people can “just tell” how grateful we are. Drawing on research from Nick Epley and others, we explore how gratitude rewires the brain, boosts well-being, and strengthens relationships, and we share simple, science-backed nudges to help you connect more deeply with the people you love this holiday season.

What if the gender revolution never finished? Economist Corinne Low joins us to unpack why women have transformed the workforce while men’s roles at home have barely changed. Drawing on insights from her book Having It All, Corinne reveals why so many families are stretched thin, caught between data, social pressure, and outdated norms. Together, we explore what it means to “have it almost,” and how smarter boundaries, parental leave, and fairer divisions of labor could finally help us reach true balance at home and at work.  ©2025 Behavioral Grooves Topics [0:00] Intro and Speed Round with Corinne Low [8:30] Gender Roles in Parenting [18:58] Behavioral and Social Norms in Parenting [27:32] Economic Models and Marriage [38:29] Paternity Leave and Gender Roles [44:18] Structural Changes and Workforce Adaptations [52:49] Desert Island Music [55:26] Grooving Session: Finding Balance at Home and at Work ©2025 Behavioral Grooves Links About Corinne Having It All: What Data Tells Us About Women’s Lives and Getting the Most Out of Yours by Corinne Low, PhD Join us on Substack!

Financial advisor and author Mark Matson joins Behavioral Grooves to explore what the American Dream means today—and whether it’s truly attainable for everyone. We dig into his view that fulfillment comes from mindset, not money, and examine how behavioral biases can sabotage our financial decisions. But as we discuss the tension between personal responsibility and systemic headwinds, we also ask: can discipline and optimism alone really guarantee success?

How does framing influence the way we think, feel, and act? Sociologist and author Mikael Klintman joins us to explore how framing shapes nearly every part of life — from art and politics to health and everyday conversations. We discuss how subtle shifts in language and context can change our perceptions, why framing itself is neutral but powerful, and how expanding or contracting our frames can unite or divide us. Tune in for practical insights on recognizing framing in action and using it to see the world differently.

This Halloween, we dive into the spooky science of superstition—why we knock on wood, wear lucky socks, and believe in things that defy logic. From the psychology of control and uncertainty to research on how superstition both stresses and strengthens us, we mix science, humor, and a dash of Stevie Wonder to show why “superstition ain’t the way.” Topics [0:00] Happy Halloween from Behavioral Grooves!

Psychologist and author Dr. Wolfgang Linden joins us to explore why so much of our stress comes not from events themselves, but from our attempts to control them. Drawing on 40+ years of research and clinical experience, he breaks down the “illusion of control” and argues that we only truly have power over two things: how we respond and where we direct our energy. We dive into his emotion–thought–behavior framework, the dangers of suppressing emotions, and how small shifts in attention and behavior can interrupt toxic cycles. From relationships to health to life goals, Wolfgang shows how letting go can actually give us more peace, more agency, and a clearer path forward—sometimes even by knowing when to quit.

We explore the hidden forces of status and anointment with Professor Toby Stuart, author of Anointed: How Status Shapes Our Lives. Status influences careers, relationships, and how we perceive art, yet as AI blurs traditional markers of merit, society is increasingly relying on shortcuts like pedigree and recognition. We examine the risks, opportunities, and compounding effects of status, revealing how small advantages snowball into lifelong impacts and challenging listeners to rethink how status shapes their world. ©2025 Behavioral Grooves Topics [0:00] Intro and Speed Round with Toby Stuart [8:43] Status-based Bias [13:49] Status in Art, Music, and Science [26:34] The Power of Anointment and Status Transfer [39:39] Status Hierarchies, Networks, and Social Groups [43:23] The Cosmic Lottery [48:06] The Future of Status in an AI World [58:47] What is the Matthew Effect?

Bob McKinnon—host of the Attribution podcast and author of America’s Dreaming—joins us to unpack the stories we tell about success and failure. Bob challenges the “fundamental attribution error,” showing how luck, privilege, and social connections shape life outcomes far more than we often admit. Together, we explore the ethics of marketing, the hidden role of systemic barriers, and how reframing our narratives can foster empathy and bridge divides. With storytelling, history, and even music woven in, this conversation reveals how compassionate curiosity can help us see both ourselves and others more clearly.
