Chapter 2: What is the significance of common knowledge in society?
You're listening to TED Talks Daily, where we bring you new ideas to spark your curiosity every day. I'm your host, Elise Hu. Where does common knowledge come from? Why is it that we know not to lie, or not to insult people to their faces, or even that the use of nuclear weapons is unthinkable today? In this hilarious and poignant talk, the sixth TED Talk, by experimental cognitive scientist Steven Pinker, he digs into the logic of societal norms.
and warns that our common acceptance of the way things are is actually under threat. And what else is at stake if we lose them?
When the little boy said the emperor was naked, he wasn't telling them anything they didn't already know. But he added to their knowledge nonetheless. By blurting out what everyone could see within earshot of the others, he ensured that everyone else knew what they knew, that everyone knew that, and so on. And that changed their relationship with the emperor, from obsequious deference to ridicule and scorn.

and you know it, but in addition, I know that you know it, and you know that I know it, and I know that you know that I know it ad infinitum. Of course, the reason that common knowledge is significant is that it is essential for coordination. In a classic example from Thomas Schelling, a couple is separated in Manhattan, incommunicado, and somehow must find each other.

Chapter 3: How does common knowledge affect coordination in relationships?
Hän tietää, että hän ymmärtää, että hän ymmärtää, että hän ymmärtää, että hän ymmärtää, että hän ymmärtää, että hän ymmärtää, että hän ymmärtää, että hän ymmärtää, että hän ymmärtää, että hän ymmärtää,
Meanwhile, she is whipsawed by the same futile empathy. Nothing short of common knowledge can guarantee that they'll end up at the same place at the same time. Of course, no one can think an infinite Russian doll of I know that she knows that I know that she knows thoughts. Our heads start to spin with three or four layers, let alone an infinite number.
In a well-known episode of Friends, Phoebe says to Rachel, they don't know we know, they know we know. Joey, you can't say anything. And he replies, I couldn't even if I wanted to.
Yleensä yleinen tieto voidaan käsitellä yksinkertaisella mentaali-intuisialla, että jotkut asiat ovat yleisöllä, yksinkertaisilla tai ulkopuolella. Tämä voidaan käsitellä suoraan puheeseen, kuten meidän yksiköiden tapauksen tapauksessa, telefonin puheluun. Oikeastaan koordinoinnin ratkaiseminen voi olla syytä, miksi kielten käsitys alkoi ensimmäiseksi.
In the absence of a public event, the next best thing is conspicuous salience, or a focal point. Schelling suggests that our couple might gravitate toward the big clock in Grand Central Station, even if it wasn't particularly close to the point at which they'd been separated, simply because each might anticipate that it would pop into the mind of the other.
A third solution is a convention. A tacit agreement to do something in a certain way for no other reason than they have agreed to do it that way, which is reason enough. Our separated couple might agree that should they ever be separated in the future, they will adopt the convention of chivalry and go to the bookstore. Or patriarchy and go to the camera store.
or whimsy and go to a lost and found in a department store, or fairness and take turns or flip coins. At larger scales, common salience or focal points and conventions drive a lot of our legal and financial coordination. An everyday example is driving on the left.
tai toisella puolella. Se ei välttämättä välttämättä välttämättä, kun kaikki yrittävät mennä samalla puolella. Kuten jokaisella naisella, joka kutsuu isänsä huomenna päivänä ja sanoo, että ole varma, kaveri, radio kertoo, että on maniakki, joka käy väärällä puolella. Hän sanoo, että on yksi maniakki, jolla on kymmeniä.
Another everyday example is money. I accept a piece of paper in exchange for an old chair because I know that my grocer will accept it in exchange for some groceries because he knows his supplier will accept it, and so on. Now, not all the examples are this obvious.

Chapter 4: Why do autocrats fear public protests and demonstrations?
Yhteistyön ja yhteiskunnallisen tietojen logiikki tarkoittaa, miksi me kaikki haluamme hyppokriisiä, valkoisia lieviä ja yksityiskohtaisia yhteiskunnallisia sopimuksia, mutta emme halua elää ilman niitä, kuten dystopialliset komediit kuten Liar Liar sopivat.
Olemme yhdessä yhdessä ymmärrettynä yksinkertaisesta loistumisesta ja rauhallisuudesta. Olemme yksinkertaiset, me tiedämme, että ne ovat fiktioita, mutta tekemällä näitä rauhallisia asioita yksinkertaisena tietoana, voidaan rauhoittaa yksinkertaiset ajatukset, jotka voivat saada meidät mukaan.
We also have to get along in less intimate relationships, and in those cases we rely on norms, ways of living together that aren't written down by lawgivers or enforced by the police, but exist because everyone knows they exist. In social life, basic civility depends on norms, such as that you don't brazenly lie, you don't insult people to their faces, you don't prosecute personal vendettas.
Antarkalaisessa globaalisessa arenaa rauha riippuu normeista, kuten se, että kansanvaltioita on imortaleja, kansalliset rajoitteet ovat perustettuja, rauha on epätarkoitettavaa ja sotilaalliset sotilaat ovat epätarkoitettavaa. Nämä normit ovat rauhoittaneet mitenkään muuta kuin yksinkertaiselta, joten ne ovat vaikuttavia rauhoittamiseen, jos ne ovat yksinkertaisesti rauhoittaneet, tai vaikka niistä rauhoittamista ei ole mitenkään.
I hope that having explained the logic behind human harmony, I don't have to explain how these norms are currently under threat or what is at stake if we lose them. As a man once said, what's there to say is so obvious. Thank you. That was Steven Pinker at TED 2025.

Chapter 5: What examples illustrate the impact of common knowledge on investing?
On the TED Radio Hour. Don't you hate it when leftover cilantro rots in your fridge? I have to tell you, cilantro is like my nemesis. Food waste expert Dana Gunders says that's just a hint of a massive global problem. Food waste has about five times the greenhouse gas footprint of the entire aviation industry. Ideas about wasting less food. That's next time on the TED Radio Hour from NPR. Listen and subscribe to the TED Radio Hour wherever you get your podcasts.
