Quantitative, contrarian, and nuanced: these are the hallmarks of the Freakonomics approach. Hear journalist and podcaster Stephen Dubner speak with EconTalk's Russ Roberts about the 20th anniversary of the popular-economics book Dubner co-authored with Steven Levitt. They discuss how the book came to be, how the journey changed Dubner's life, and how it changed his thinking about various economics issues. The conversation includes a lengthy discussion on the role of private equity in the American economy, and Roberts's claim that Dubner and co-author Steven Levitt's treatment of incentives overlooks the role of competition and markets.

What drives the seeming relentless dynamism of Tokyo? Is there something special about Japanese culture? Joe McReynolds, co-author of Emergent Tokyo, argues that the secret to Tokyo's energy and attractiveness as a place to live and visit comes from policies that allow Tokyo to emerge from the bottom up. Post-war black markets evolved into today's yokocho--dense clusters of micro-venues that turn over, specialize, and innovate nightly--while vertical zakkyo buildings stack dozens of tiny bars, eateries, and shops floor by floor, pulling street life upward. The engine? Friction-light rules: permissive mixed-use zoning, minimal licensing, and no minimum unit sizes let entrepreneurs launch fast and pivot faster. And surrounding this emergent urban landscape there's plenty of new housing with excellent transportation infrastructure to let ever-more people enjoy Tokyo's magic.

Status isn't fixed; it's transferred and "bestowed," shaping who gets resources, attention, and opportunity. So argues author Toby Stuart of UC Berkeley in his book, Anointed. He and EconTalk's Russ Roberts explore why hierarchies persist--reducing conflict, allocating scarce resources, and curating our overwhelming choices--and how endorsements, blurbs, and brands quietly steer our judgments, from bookstores to wine shops and art galleries. At the end, Stuart reflects on imposter syndrome and how thinking deeply about the anointed changed how he sees success.

Losing weight should be simple: eat less, exercise more. But according to author and health journalist Julia Belluz, it's complicated. Listen as Belluz talks with EconTalk's Russ Roberts about her new book, Food Intelligence. Belluz argues that a calorie is pretty much a calorie whether it's carbs or fat. Keeping calories under control is often harder than it sounds. The message isn't blame; it's agency with compassion: understand your body's feedback loops, redesign the choices around you, and choose a sustainable way to enjoy food. At the end of the conversation, Belluz makes the case for government intervention of various kinds to help us make what she sees as better food choices; Roberts pushes back.

Why are Super Bowl ads so good for launching certain kinds of new products? Why do we all drive on the same side of the road? And why, despite laughing and crying together, do we often misread what others think? According to bestselling author and Harvard psychologist Steven Pinker, it all comes down to common knowledge, or the phenomenon that happens when everyone knows that everyone else knows something. Hear Pinker and EconTalk's Russ Roberts explore the necessary conditions for that knowledge, and how it can be both vital and dangerous to societies, depending on how it's used. They discuss, among other things, game-theory puzzles, how laughter spreads, how totalitarian regimes exploit uncertainty about who knows what (even when they don't), and why we often don't say explicitly what we really mean to say.

American manufacturing of aircraft during WWII dwarfed that of its enemies. By the end of the war, an American assembly line was producing a B-24 bomber in less than an hour. But that success was far from inevitable. Structural engineer and writer Brian Potter speaks with EconTalk's Russ Roberts about the logistical challenges of ramping up production from virtually nothing, and the incredible balance of precision and improvisation required to respond to constantly changing aircraft designs. They also discuss the limits of industrial mobilization, why early preparation proved so critical, the role of women in the production process, and what lessons this experience can offer today's debates about supply chains and defense readiness.

What makes some groups thrive while others crash and burn? According to organizational-behavior scholar Colin Fisher, the real villains are rarely individuals, but dysfunctional teams and organizations.

They speak about why most team-building exercises are usually a waste of time, and why the best way to build trust is simply to do the work. Finally, they explore the role of great leaders from Steve Jobs to Bill Belichick in elevating groups into teams, and offer lessons from history's great projects for increasing productivity.

Listen as she speaks with EconTalk's Russ Roberts about how research has skewed our understanding of animals' capabilities, the surprising inner lives of animals, and how a shift from dominance toward connection with the larger living world can help humanity.

Former submarine commander David Marquet joins EconTalk's Russ Roberts to explore how distancing--thinking like someone else, somewhere else, or sometime else--can unlock better choices in business and life. They talk about leadership without giving orders, how to empower teams, and what it means to see yourself as a coach rather than a boss. Along the way, they discuss Jeff Bezos's leap to start Amazon, Steve Jobs' unique vision, and how a simple mindset shift can transform a struggling crew--or your career.

What do we lose when every moment is recorded, every action scrutinized, and every past mistake preserved? Philosopher and author Lowry Pressly joins EconTalk's Russ Roberts to discuss why privacy isn't just about secrets or information control, the necessity of spontaneity, the importance of moral growth, and what we need to become fully human. From photography to forgetting, surveillance to selfhood, this episode challenges our assumptions about what it means to be seen--and unseen--in a data-driven world.

Many students graduate high school today without having read a book cover to cover. Many students struggle to learn to read at all. How did this happen? Listen as educator and author Doug Lemov talks with EconTalk's Russ Roberts about the failed fads in reading education, the mistaken emphasis on vocabulary as a skill, and the importance of background knowledge for thinking and reading comprehension. Lemov and Roberts also discuss their love of difficult-to-read authors, the power of reading in groups, the value of keeping a reading journal, and how even basketball can be more enjoyable when we have the right terminology.

Is long form reading a dying pastime? Journalist and cultural critic James Marriott joins EconTalk's Russ Roberts to defend the increasingly quaint act of reading a book in our scrolling-obsessed, AI-summarized age. He urges juggling a paper book and a Kindle, recounts ditching his smartphone to rescue his attention, and shares tactics for finding the "right" beach novel and biography. He and Russ also debate the value of re-reading, spar over Dostoevsky, celebrate Elena Ferrante, and swap suggestions for poetry that "puts reality back in your bones." Throughout, they argue that the shallowness of social media makes the best case for diving into the dense, intellectually difficult, yet uniquely transformative power of books.

Chris Arnade speaks with EconTalk's Russ Roberts about a different way to travel. Listen as Arnade shares what he learned from Istanbul's small community mosques and how Avignon's Congolese-neighborhood cathedrals provided moving moments of spirituality. He also explains why Japan and Vietnam's emphasis on community lends itself to more happiness than America's "me-focused" approach, and what gear he carries--and leaves behind--for his extremely long walks through the world. Finally, he offers suggestions for choosing places to eat on the road that can elevate meals into meaningful experiences. This is a thoughtful conversational journey about veering off the beaten path to find home in surprising places.
