"So what innuendo, euphemism, and indirect speech acts do is prevent the proposition from becoming common knowledge. That is, let’s say he said, “Do you want to come up for Netflix and chill?” She says no. She’s a grown-up; she knows this was a sexual invitation. And he’s a...

I'll be giving talks on common knowledge in Australia and New Zealand in February 2026. Tickets : "I begin the book with the story of The Emperor’s New Clothes because it’s the quintessential illustration of common knowledge. When the boy said the Emperor was naked, he wasn’t telling anyone anything they didn’t already know. They could see the Emperor was naked, but he changed the state of their knowledge nonetheless because, by blurting it out within earshot of everyone, now everyone knew that everyone else knew that everyone else knew that everyone else knew that the Emperor was naked. So it shows, first of all, that even though the concept of common knowledge, as I defined it, seems impossible—your head starts to spin after, you know, one or two “I know that she knows,” let alone an infinite number. But what the story shows is that a conspicuous, public, self-evident event—something that you see while you see everyone else seeing it, or you hear when you know everyone else can hear it—can give you common knowledge at a stroke. And the other moral is that it changed the relationship of the people to the Emperor, from obsequious deference to ridicule and scorn. And a major theme of the book is that common knowledge, even though it sounds like this abstruse, recondite academic concept, actually figures into everyday life, figures into our money, and figures into our politics, because it enables coordination and it changes social relationships."

Me: I discuss in the book—it refers to the state where I know something, you know something, I know that you know it, you know that I know it, I know that you know that I know it, and so on ad infinitum. So it differs a bit from the conventional usage, which just refers to something that everyone knows. Here, everyone has to know that everyone knows. Times Radio Interviewer (Daniel Finkelstein Daniel Finkelstein): Can I use this with reference to the interview that I did yesterday with my brother? My brother’s a professor at City University; he’s president of the university, and there’s a campaign at the moment going on against one of their professors who was in the Israeli Defense Forces in the 1980s. We were having a discussion about how the university was standing up for the free speech of its staff, and I’d begun to wonder, as I went home reading your book on the tube, whether I’d made a big mistake—because the protest against this professor is really just a coordination exercise, isn’t it? And maybe I’d aided it by talking about it. Me: Oh yes—protests are coordination exercises. They’re designed to make private knowledge common knowledge. So, in a repressive regime, everyone may know that they despise the government, but because criticism of the government is punished, people might keep their opinions to themselves, with a result that they really don’t know what their fellow citizens think. Each one might think that they’re the only ones that are disgruntled, and so they can’t fear standing up to—they fear standing up to oppose the regime, because they can be picked off one at a time. If everyone were to protest at once, no government has the firepower to intimidate all its citizens at once. In a public protest, people can see other people there, and they know that the people there see other people there, and that can give them the strength and numbers to oppose the regime—sometimes by literally storming the palace, or sometimes just bringing the machinery of the state to a halt through work stoppages. But the crucial thing is that they are coordinated. They can only be coordinated if everyone knows that everyone knows that they hate the regime. Daniel Finkelstein: I suppose that social media is making people—is increasing the stock of common knowledge. We’re all much more aware of what other people like us, in particular like us, know, and we also know that other people know it, and so on, as you put it, and that makes people have more common knowledge. It’s not making us happier though; maybe we’d be better with less common knowledge? Me: Social media are making us more connected within certain circles—that is, those who are receiving the same texts and feeds that we are. It reduces the pool of, or shrinks the largest pool of common knowledge, namely the whole country, which may have been accessible in a day in which, say, in the United States there were three networks, or in Britain everyone was listening to the BBC. And yes, it probably doesn’t make us as happy, because when everything is public, it means that your reputation is on the line for anything you say or do. It means that since social media allow us to generate common knowledge, not just receive it like in the old days, it means that attacks on people’s reputation can be common knowledge, which means that it’s all the more painful for people on the receiving end of the attack. It may have something to do with the fact that in certain demographics—especially young people whose lives increasingly are online—that there’s that much more social competition, opportunities for gossip and ostracism and demeaning comments, and so on.

On Friday, Bill Maher asked me if what happened with Biden at the disastrous debate with Trump was the same story as the Emperor's New Clothes. Me: The story of the Emperor's New Clothes is a story about common knowledge, because when the kid blurted it out, he actually wasn't telling anyone anything they didn't already know. They could see the Emperor was naked. But he still changed their knowledge, because by blurting it out with an earshot of the others, now everyone knew that everyone else knew that everyone else knew that everyone else knew. And what that allowed them to do is change their relationship with the Emperor, from obsequious deference to ridicule and scorn. And the thing about common knowledge in the social realm is that it's what props up our social relationships. And so when something is blurted out, then it can change everything. It changes the nature of your relationship with someone. Maher: And we do have sort of a modern version of the Emperor parable, which is Joe Biden. I mean, he was the Emperor who everyone wouldn't say had lost his marbles. I mean, is that not really the same story? Me: It is the same story, because opinion polls showed that after that disastrous debate with Trump, the number of people who thought that he was cognitively impaired didn't go up by that much. It went up by a few percentage points. But before, a majority of people thought that he was cognitively impaired. The difference is, when it's on TV, where you're watching it, you know that the rest of the country is watching it, you know the rest of the country knows the rest of the country, it's no longer private. It's common. And that's when he was challenged. That was the end. Bill Maher Real Time with Bill Maher

With The Fifth Column 🖐 talking about common knowledge: “Common knowledge can be generated at a stroke when something is witnessed in a forum where you can witness other people witnessing it. So if something just happens in public and you can see everyone else seeing it, that gives you an instant intuition that there’s common knowledge. Humor, I suggest in one of the chapters, is a common-knowledge generator, usually of some infirmity or indignity or weakness in someone or something. And the laughter, which is conspicuous—you can hear it when someone is laughing; it interrupts their speech and breathing—at the moment of laughter, suddenly becomes common knowledge. Everyone who gets the joke suddenly realizes that someone has been taken down, and they realize that everyone else realizes it. And that’s why freedom of speech and freedom of assembly are suppressed in autocracies. The joke from the Soviet era is about the man handing out leaflets in Red Square. Of course, the KGB arrest him, take him down to headquarters, only to discover that the leaflets are blank sheets of paper. They say, ‘What is the meaning of this?’ And he says, ‘What’s there to say? It’s so obvious.’ And the reason that it was subversive is that he was generating common knowledge. Just the mere fact of trying to make something public, even if you don’t have to stipulate what it is, can generate the coordination—everyone acting together to bring down a regime.”

I’ve had a lot of people say Candace will move to Russia soon. I don’t think so. Her visit didn’t go well. I watched many of the PR interviews they set up for her and they were disasters. I don’t know if it was a language barrier that made her come off as so stupid or if she didn’t want to really talk but she didn’t do well in any of them. She couldn’t even answer the questions they asked many times. One interviewer had to ask her twice many questions. She answered most every question with “family is important” for an hour. It was weird. The next interview (and I’ll post it again here) is a friend of Putin and I guess didn’t know she was Catholic. Because he basically said the Catholic Church was corrupt and satanists. They had become super liberal even so much so that they did same sex marriages. And that France and the opening of the Olympic Games proved it. You could see she was upset and instead of defending the Church as not liberal or corrupt, she went on a Bridgette and France is bad answer. I think one reason she did that is she knew this guy was Putins friend and popular in Russia. She couldn’t push back on him. She was clearly not comfortable the entire interview. 30 minutes in she cut the interview and said we need to close it here. Her interviews were a disaster, her security guy almost died (I’m still on the fence about the story on why he was sick) and Ukraine bombed close to the hotel and event. She can say all she wants Russia is amazing. She’s lying. I think she found out just how not amazing it is.

WATCH: Jill Biden says she had to walk out of the room after Kamala Harris pressured Joe Biden to endorse her immediately after dropping out of the 2024 presidential race RITA BRAVER: So he decided that it was- he was going to drop out. JILL BIDEN: That’s right. BRAVER: It was Sunday, July 21st, 2024. Before your husband made the announcement. he called Vice President Harris to tell her what he had decided, and you said almost as soon as he gave her the news, she demanded that he endorse her right away, and he- he, I mean, did you think something was off about that? BIDEN: You know, I'm sure she thought about it. You know it wasn't like a call out of the blue. I'm sure with everything happening at that time it had to cross her mind so I think, um, I think that's what- BRAVER: When you said it was back and forth because she wanted him, um, to endorse her at the same time he announced that he was dropping out and he wanted to just make the announcement of the dropout first, right? BIDEN: Oh yeah, sure. BRAVER: And you said you even walked out of the room because it was- got too tense maybe? BIDEN: Well, it was just, I'm telling you, it was so hard. I mean this is what Joe had worked for all his life. He loved being a statesman. Um, he loved the job of helping the American people and to give it up. I mean Rita, he did it for over 50 years of his life. That's a long time. And so at some point when all of this is going on. It gets a little overwhelming, and yes, I had to walk out.
