Podcasts about Common knowledge

What's common about common knowledge, and how does it become common? Common knowledge—the awareness of how others think and even how others think others think—is needed for social coordination, things as basic as driving on the same side of the road or using paper currency. And it has a hidden logic that makes it all work. Cognitive psychologist and author Steven Pinker returns to Commonwealth Club World Affairs in Silicon Valley to explore some of the paradoxes of human behavior. It's the subject of his latest book, When Everyone Knows That Everyone Knows . . .: Common Knowledge and the Mysteries of Money, Power, and Everyday Life. Pinker addresses issues as seemingly disparate as why people hoard toilet paper when an emergency breaks, why crypto ads clog up Super Bowl advertising, why Russian officials arrested a protester carrying a blank sign, or even why everyone seems to agree that life would be unbearable if everyone was completely honest at all times. Tying it all together, he says, is our ability to know what others think and what others think about what others think . . . on and on, ad infinitum. Learn more about your ad choices.

As promised, today we're bringing you a full-length interview with Steven Pinker about his new book, When Everyone Knows That Everyone Knows . . .: Common Knowledge and the Mysteries of Money, Power, and Everyday Life. What is common knowledge? For Steve, it is not conventional wisdom. Instead, it's when everyone knows something and everyone knows that and everyone knows it. That may sound loopy, but the implications of common knowledge — how it's produced, sustained, and manipulated — are profound. “It's common knowledge,” Steve tells Rufus, “that makes humans human. Humans are not solitary. What makes humans humans is that we coordinate in groups — from couples to nations to, in some cases, the entire world — and I think common knowledge is the underpinning, the cement, the foundation of that ability to coordinate.” (8:00) Why “coffee” doesn't just mean coffee (14:40) What blushes and laughter unintentionally reveal (30:39) The real reason brands spend millions on Super Bowl ads (35:00) How common knowledge explains cancel culture (48:43) What happens to society when norms collapse? —

Why do people refuse to say what they see, and, what everyone knows…whether or not they're willing to acknowledge it? Is there some benefit to keeping quiet, adhering to the “unwritten rules,” and, is there a time and place to break tradition? Today, I'm joined by Harvard professor, Dr. Steven Pinker to answer these questions. We also discuss the difference between common knowledge and common wisdom, whether or not it's hypocrisy to stay quiet about the unwritten rules, when to be radically honest or complacently quiet, how to judge risk in your honesty, how the “Abeline Paradox” will serve you, and the importance of male initiation.

Steven Pinker joins to discuss his new book, When Everyone Knows That Everyone Knows: Common Knowledge and the Mysteries of Money, Power, and Everyday Life, exploring how shared awareness coordinates everything from markets to manners. He traces spirals of silence, costly signals, and why a single public moment can flip private hunches into history. Also: the sentencing in the intended assassination of Justice Brett Kavanaugh — what the court record shows about Nicholas (Sophie) Roske's change of mind, and why eight years can be both just and long. And in the Spiel: the Supreme Court's new term, and an un-panicked look at Trump's shadow-docket “wins,” what the justices actually stayed, and why.

Iconic entertainer Rosie O’Donnell is one of the most fearless voices of our time, a trailblazing comedian, actor, talk show host, and outspoken advocate who’s never shied away from speaking her truth. From her breakout in A League of Their Own and her Emmy-winning daytime show, to her bold activism and heartfelt storytelling, Rosie has spent decades making audiences laugh, think, and feel deeply. Now living in Ireland, she’s finding new meaning in life and motherhood, and she’s in Australia for the very first time with her acclaimed one-woman show ‘Common Knowledge’. In this episode, Rosie opens up about losing her mother as a child, how grief has shaped her life, and the courage it takes to keep standing up even when life (or politics) knocks you down.

Recorded live at the Comedy Cellar in New York City: I sat down with Steven Pinker, Harvard psychologist, best-selling author, and world-class debunker of doom, to talk about his new book, When Everyone Knows That Everyone Knows…:Common Knowledge and the Mysteries of Money, Power, and Everyday Life.  We got into this idea of “common knowledge”: what we all know and know that everyone else knows. It may sound abstract, but really it underlies everything. It is our shared awareness that lets us coordinate, bluff, protest, and panic together. We also talk about assassinated Turning Point USA founder Charlie Kirk, the changing style of comedy and its audience, and more. Learn more about your ad choices. Visit megaphone.fm/adchoices

The experimental cognitive psychologist and popular science writer, Steven Pinker delves into the intricacies of human interactions in his latest book, ‘When Everyone Knows That Everyone Knows...: Common Knowledge and the Science of Harmony, Hypocrisy and Outrage'. From avoiding the elephant in the room to the outing of the emperor's new clothes, Pinker reveals the paradoxes of human behaviour. Common knowledge can bind people and communities together in a shared purpose, but Aleks Krotoski, the presenter of BBC Radio 4's The Artificial Human and The Digital Human, journeys to the fringes of human endeavour in The Immortalists. There, Silicon Valley tech billionaires are using their wealth to focus on their own futures, attempting to disrupt and defy their own mortality.How people behave to strangers and how much they're willing to spend to help them, is at the heart of David Edmonds's biography of the philosopher Peter Singer. Death in a Shallow Pond considers Singer's most famous thought experiment and his contention that we're morally obliged to come to the aid of those less fortunate if we can. It's a practical philosophy that has divided opinion, but also inspired a new movement of effective altruism.Producer: Katy Hickman Assistant Producer: Natalia Fernandez

Today's big ideas come to us from Harvard cognitive psychologist, public intellectual, and bestselling author Steven Pinker, who's out with a new book called When Everyone Knows That Everyone Knows… Common Knowledge and the Mysteries of Money, Power, and Everyday Life​. In it, he shows how public, shared awareness shapes everything from markets and politics to first dates and social media pile‑ons, and why understanding it can make you a sharper decision‑maker and a better collaborator.

Steven Pinker's new book argues that all our relationships depend on shared assumptions and “recursive mentalizing” — our constant efforts to understand what other people are thinking. He and Steve talk about the psychology of eye contact, the particular value of Super Bowl ads, and what it's like to get cancelled. SOURCES:Steven Pinker, professor of psychology at Harvard University. RESOURCES:When Everyone Knows That Everyone Knows, by Steven Pinker (2025)."Why I Left Harvard," by Carole Hooven (The Free Press, 2024).Rationality: What It Is, Why It Seems Scarce, Why It Matters, by Steven Pinker (2021)."Economics of Toilet Paper X Thread," by Justin Wolfers (2020)."How a Famous Harvard Professor Became a Target Over His Tweets," by Michael Powell (New York Times, 2020)."Police Killings of Blacks: Here Is What the Data Say," by Sendhil Mullainathan (2015).SuperFreakonomics: Global Cooling, Patriotic Prostitutes, and Why Suicide Bombers Should Buy Life Insurance, by Steven Levitt and Stephen Dubner (2011).Rational Ritual: Culture, Coordination, and Common Knowledge, by Michael Suk-Young Chwe (2003)."Open Letter to the LSA." EXTRAS:"Steven Pinker: 'I Manage My Controversy Portfolio Carefully,'" by People I (Mostly) Admire (2020).

Harvard psychologist Steven Pinker shares five key insights from his brand new book, When Everyone Knows That Everyone Knows. He reveals how “common knowledge” — the hidden force of knowing what others know — shapes everything from financial bubbles and political revolutions to why we say “Netflix and chill.” Then we revisit our 2021 conversation with Steve about rationality, where he explains why smart people believe dumb things, why we're terrible at assessing risk, and how our species can be both brilliantly rational and spectacularly irrational at the same time. ——— Want to connect?

Steven Pinker (When Everyone Knows That Everyone Knows: Common Knowledge and the Mysteries of Money, Power, and Everyday Life) is a cognitive psychologist, psycholinguist, and author. Steven returns to the Armchair Expert to discuss how in general things have gotten better, that tracking the data can make one more optimistic than reading headlines, and the differences between private knowledge and common knowledge. Steven and Dax talk about how evolved language generates common knowledge, the role of conventions and ritual in human coordination, and the power of Super Bowl advertisements. Steven explains the counterintuitive fact that announcing one's philanthropy actually does more good, why we have to expose ourselves to a universe of ideas to find out which ones are good, and why he's not afraid of AI.Follow Armchair Expert on the Wondery App or wherever you get your podcasts.

Steven Pinker returns to Conversations with Tyler with an argument that common knowledge—those infinite loops of "I know that you know that I know"—is the hidden infrastructure that enables human coordination, from accepting paper money to toppling dictators. But Tyler wonders: if most real-world coordination works fine without recursively looping (a glance at a traffic circle), if these models break down with the slightest change in assumptions, and if anonymous internet posters are making correct but uncomfortable truths common knowledge when society might function better with noble lies, is Pinker's theory really capturing how coordination works—and might we actually need less common knowledge, not more? Tyler and Steven probe these dimensions of common knowledge—Schelling points, differential knowledge, benign hypocrisies like  a whisky bottle in a paper bag—before testing whether rational people can actually agree (spoiler: they can't converge on Hitchcock rankings despite Aumann's theorem), whether liberal enlightenment will reignite and why, what stirring liberal thinkers exist under the age 55, why only a quarter of Harvard students deserve A's, how large language models implicitly use linguistic insights while ignoring linguistic theory, his favorite track on Rubber Soul, what he'll do next, and more.

As a leader, psychology is fundamental to your success - whether that means understanding consumer behavior, team dynamics, or even your own biases and blind spots. Harvard professor Steven Pinker says that an important phenomena to understand is that of common knowledge and its downstream effects. It's the idea that there is power in knowledge, but also power in knowing what other people know - and that when a large group of people know what others around them know, and vice versa, that's when major change can happen. He explains how common knowledge underlies meme stocks, the rise of crypto, meeting etiquette and the success of Super Bowl ads. Pinker wrote the new book When Everyone Knows That Everyone Knows . . .: Common Knowledge and the Mysteries of Money, Power, and Everyday Life.

It's common knowledge, say, that every driver stops for a stop sign – and we shouldn't take that shared understanding for granted. Steven Pinker is the Johnstone Professor of Psychology at Harvard University. He joins host Krys Boyd to discuss the rules of society we all know and follow and the ways our world would fall apart if people disregarded this social contract. His book is “When Everyone Knows That Everyone Knows . . .: Common Knowledge and the Mysteries of Money, Power, and Everyday Life.” Learn about your ad choices: dovetail.prx.org/ad-choices

Common knowledge is necessary for coordination, for making arbitrary but complementary choices like driving on the right, using paper currency, and coalescing behind a political leader or movement. It's also necessary for social coordination. Humans have a sixth sense for common knowledge, and we create it with signals like laughter, tears, blushing, eye contact, and blunt speech. But people also go to great lengths to avoid common knowledge—to ensure that even if everyone knows something, they can't know that everyone else knows they know it. And so we get rituals like benign hypocrisy, veiled bribes and threats, sexual innuendo, and pretending not to see the elephant in the room. Pinker shows how the hidden logic of common knowledge can make sense of many of life's enigmas: financial bubbles and crashes, revolutions that come out of nowhere, the posturing and pretense of diplomacy, the eruption of social media shaming mobs and academic cancel culture, the awkwardness of a first date. Steven Pinker is the Johnstone Professor of Psychology at Harvard University. He is an elected member of the National Academy of Sciences, a two-time Pulitzer Prize finalist, and one of Time's “100 Most Influential People in the World Today.” He has won many prizes for his teaching, his research on language, cognition, and social relations, and his twelve books. His new book is When Everyone Knows That Everyone Knows: Common Knowledge and the Mysteries of Money, Power, and Everyday Life.

Why what isn't said can communicate more than what is spoken.We often speak in hints and half-truths, not because we can't be direct, but because subtlety protects our relationships. “An awful lot of the time, we don't just blurt out what we mean,” says Steven Pinker. “We hint, we wink, we beat around the bush — counting on our listener to read between the lines, connect the dots, catch our drift.”Pinker is the Johnstone Professor of Psychology at Harvard University, a celebrated linguist and cognitive scientist, and the author of twelve influential books. His latest, When Everyone Knows That Everyone Knows: Common Knowledge and the Mysteries of Money, Power, and Everyday Life, explores how our shared understanding of awareness — what Steven refers to as common knowledge — and the way we signal it, governs everything from friendships to authority to negotiations. “Common knowledge is what ratifies or annuls social relationships, and that's why blurting something out that contradicts the assumptions of the relationship can blow everything up and be deeply awkward.” In this episode of Think Fast, Talk Smart, Pinker joins host Matt Abrahams to discuss why humans lean on innuendo, euphemism, and strategic ambiguity. They examine how culture and context shape what we hear, why our social fabric depends on more than just literal meaning, and offer practical ways to refine our communication by paying attention not just to what we say, but to what others know we know.To listen to the extended Deep Thinks version of this episode, please visit FasterSmarter.io/premium.Episode Reference Links:Steven PinkerSteven's Book: When Everyone Knows That Everyone KnowsEp.91 Um, Like, So: How Filler Words Can Create More Connected, Effective CommunicationEp.225 Speaking Fluent Internet: How Algorithms Are Changing the Way We Speak  Connect:Premium Signup >>>> Think Fast Talk Smart PremiumEmail Questions & Feedback >>> hello@fastersmarter.ioEpisode Transcripts >>> Think Fast Talk Smart WebsiteNewsletter Signup + English Language Learning >>> FasterSmarter.ioThink Fast Talk Smart >>> LinkedIn, Instagram, YouTubeMatt Abrahams >>> LinkedInChapters:(00:00) - Introduction (02:23) - Why We Speak Indirectly (06:39) - The Role of Context (10:35) - Cross-Cultural Perspectives (11:51) - Hypocrisy as Social Glue (13:43) - Clarity, Conciseness, & Grace (17:07) - Metaphors We Live By (20:06) - The Final Three Questions (24:02) - Conclusion ********Thank you to our sponsors.  These partnerships support the ongoing production of the podcast, allowing us to bring it to you at no cost.Build a better website with Squarespace today.

Listen as I begin this episode by explaining why you most likely could not. https://www.sciencedaily.com/releases/2015/06/150623200016.htm?utm_source=chatgpt.com Common knowledge is something that I know that you know, and you know that I know you know it! And so usually, we never discuss it. Sounds confusing but without common knowledge life would be amazingly difficult and tedious as you are about to discover when you listen to my conversation with Steven Pinker. Steven is a professor of psychology at Harvard University and is the author of 12 books. His latest is When Everyone Knows That Everyone Knows . . .: Common Knowledge and the Mysteries of Money, Power, and Everyday Life (https://amzn.to/46oYRdG). Some people are chronically late. It's as if they have a completely different attitude toward time. Yet their tardiness can infuriate people who are punctual and expect other people to be. Is it rudeness or is it just a different “time personality”? There was an interesting article about this in the New York Times not long ago that got quite a bit of attention. Joining me in this episode is the author of that article, Emily Laber-Warren.

Getting along in society requires that we mostly adhere to certainly shared norms and customs. Often it's not enough that we all know what the rules are, but also that everyone else knows the rules, and that they know that we know the rules, and so on. Philosophers and game theorists refer to this as common knowledge. In Steven Pinker's new book, When Everyone Knows That Everyone Knows..., he explores how common knowledge (or its absence) explains money, power, and a wide variety of subtextual human interactions.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2025/09/22/329-steven-pinker-on-rationality-and-common-knowledge/Support Mindscape on Patreon.Steven Pinker received his Ph.D. in psychology from Harvard University.

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.

Rosie O’Donnell has lived almost every version of life in the spotlight. From her breakout in Hollywood alongside Tom Hanks and Madonna, to her groundbreaking daytime talk show that redefined television, Rosie was one of the most famous women in America. But with fame came ridicule, public feuds, and moments that cut deeply. She’s been celebrated, mocked, and at times turned into the punchline of her own story. And one of the most painful moments came when Ellen DeGeneres told the world they weren’t friends. In this conversation, Rosie is raw, funny and reflective. She speaks about growing up in the shadow of losing her mother, her shy first attempts at romance, the highs and lows of talk show success, and the very public feuds that made headlines. She shares what it was like to be blindsided by Ellen’s rejection, and why that moment stayed with her. And yes, she even talks about her recent return to our screens in And Just Like That. Rosie O’Donnell has lived a big, messy, fascinating life — and in this episode, she tells it all. You can follow Rosie O'Donnell here.
