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.

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.

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.

Are humans the most intelligent species, or just the most arrogant? NYU primatologist Christine Webb, author of The Arrogant Ape, believes that human exceptionalism is a myth that does more harm than good. 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.

Cold plunges. Exogenous ketones. Pu-erh tea--but hold the breakfast: it's all par for the morning routine, at least if you're entrepreneur, self-experimenter, and king of the lifehacks, Tim Ferriss. From how he manages the challenges of his celebrity to how he manages to stay in great shape; how he does--and when he doesn't--harness the power of AI; and how he preps for a podcast designed to help us live richer, fuller, and healthier lives, the bestselling 4-Hour Workweek author and billion-downloads podcaster speaks with EconTalk's Russ Roberts about what it's really like to be him, and more.

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.

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?

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.
