From one of the world's most celebrated intellectuals, a "fascinating" (Financial Times), brilliantly insightful work that explains how we think about each other's thoughts about each other's thoughts, ad infinitum. It sounds impossible, but "superlatively gifted science writer" (The Times) Steven Pinker shows that we do it all the time. This awareness, which we experience as something that is public or "out there," is called common knowledge, and it has a momentous impact on our social, political, and economic lives.
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: everything from rendezvousing at a time and place to speaking the same language to forming enduring relationships of friendship, romance, or authority. 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. Artists and humorists have long mined the intrigues of common knowledge, and Pinker liberally uses their novels, jokes, cartoons, films, and sitcom dialogues to illuminate social life's tragedies and comedies. Along the way he answers questions like:
-Why do people hoard toilet paper at the first sign of an emergency?
-Why are Super Bowl ads dominated by crypto?
-Why, in American presidential primary voting, do citizens typically select the candidate they believe is preferred by others rather than their favorite?
-Why did Russian authorities arrest a protester who carried a blank sign?
-Why is it so hard for nervous lovers to say goodbye at the end of a phone call?
-Why does everyone agree that if we were completely honest all the time, life would be unbearable?
Consistently riveting in explaining the paradoxes of human behavior, and "one of the most insightful books…about what makes us human" (Bill Gates), When Everyone Knows That Everyone Knows… invites us to understand the ways we try to get into each other's heads and the harmonies, hypocrisies, and outrages that result. Steven Pinker is the Johnstone Professor of Psychology at Harvard University. He has won many prizes for his teaching, his research on language, cognition, and social relations, and his twelve books, including The Language Instinct, How the Mind Works, The Better Angels of Our Nature, and Rationality. 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." "Fred Sanders delivers this audiobook about metacognition with a perfect balance of erudition and approachability. Psychology professor Pinker describes how we understand our thoughts and how we know what others are thinking. To frame this discussion, he evokes the classic moment from the '90s television show "Friends," the one in which Phoebe realizes "they don't know we know they know!" That scene played for laughs, but Pinker is seriously applying this approach to the understanding of shared knowledge, as well as how we can be misunderstood. Social media is rife with examples of attempts at humor or sarcasm being taken out of context. Sanders doesn'
