Hello, OddLots listeners. You are listening to another episode that was recorded live in New York City at our event on June 26th. This time it's with the one and only Nim Nicholas Taleb, distinguished scientist and adviser at Universa Investments.

塔勒布对“美好生活”的定义

主持人: 塔勒布,您对美好生活的定义是什么?我们应该追求什么?

View/Hide Original English

Nim, what's your definition of a good life? What should we be aiming for?

纳西姆·塔勒布: 很多人认为我们生来就是为了快乐等等。事实上,我们被设定为感到“有用”。

View/Hide Original English

I mean the the a lot of people think that we're programmed to be happy and stuff like that. In fact, we're programmed to feel useful.

这就是美好生活。或者说,你不需要成为烈士才能感到有用。事实上,烈士们走得太远了,如果你回顾历史中他们的死亡,你会发现他们本可以再等十年,问题就会自行解决,对吧?所以想想所有的战争,比如越南战争就自行解决了,或者其他什么。所以,让我们忘记殉道,当然,除了在少数情况下,比如你救了某人。所以,核心思想是“对他人有用”,然后,随着年龄增长,分享你的错误,让社会能在此基础上发展。这就是我对美好生活的看法。对很多人来说,美好生活是享乐主义的(hedonic: 追求感官快乐的),比如他们会请欧洲的厨师飞过来,做一些复杂的食物,而我们的朋友可能不会赞同吃那些不是牛排、名字冗长的复杂食物。所以,那是一种享乐主义的方法。而我的方法是让你感到有用。所以,无论你是否有家庭并为他们提供支持,或者对于很多还没有家庭或可能没有家庭的人来说——因为过去大多数人没有家庭,很多人是孤儿,很多人没有存活下来的孩子——所以,核心思想是“对整个社区有用”。

View/Hide Original English

That's a good life. Or I mean you don't have to be martyr to feel useful. As a matter of fact, martyrs go too far and if you look at their death typically in history, you realize they could have waited a decade and the problem was solved itself by self, right? So think of all the wars and hey the Vietnam war took care of the self or the so whatever. So, so let's forget about martyrdom except of course in narrow cases where you save someone. So the idea is to be useful to others and then the idea is you know to share your mistakes as you grow in age to share your mistakes with society so they can build on it. That's my idea of a good life. For a lot of people, good life is hydonic in the sense that they have a chef flown in from Europe to eat some complicated food uh that our friend here, you know, just would not approve eating, you know, not nonstakes and complicated thing with long long names and uh so that that's a hydonic approach to things. Mine is you feel useful. So whether you have a family and you're providing for them or if for a lot of people who don't have a family yet or may not have a family because in the past most people didn't have a family a lot of people were orphans a lot of people were uh had didn't had children who didn't survive so the idea is to be useful to the community in general.

信息消费与贡献

主持人: 我们一开始在市场背景下讨论过这个问题,但你知道,我总觉得有一种冲动,想一直看手机,关注最新的头条新闻。有时我觉得自己不是一个好家长,因为我本该和家人在一起的时候却在看手机,就像你提到的那样。我们如何才能变得有用呢?我们被超出我们控制的事件轰炸着。

View/Hide Original English

So we talked about this in the market context at the very beginning but does you know I feel this poll to basically always look at my phone to monitor the latest headlines. Sometimes I don't think like I'm the best parent because I'm looking at my phone when I should be with my family as you mentioned. How do we be useful? Bombarded time we're just being bombarded with events beyond our control.

纳西姆·塔勒布: 嗯,但我们现在比以前好多了。四十、五十年前,在许多人甚至你出生之前,我们并不了解我们花了一个世纪的时间在电视机前。

View/Hide Original English

Okay. Yeah. But but you're we're better off than we were today. Um 40 years 50 years ago before many were born perhaps even you. Right. So the you don't realize that we spend about a century in front of a TV set.

主持人: 哦,对了。

View/Hide Original English

Oh that's right.

纳西姆·塔勒布: 或者阅读报纸,你只是被动地接收信息,却没有提供任何回报。那是一个集中的信息时代,始于现代。你会看到家庭在电视机前吃饭。你基本上只是在接收信息,而在过去,我们处理信息的方式是有机地通过“交换”信息。这就像Twitter(推特:一个社交媒体平台)。你发布信息,你接收信息。所以你去理发店,有人给你信息,然后你去买鱼,你给鱼贩信息,然后谣言就开始传播。现在我们又回到了那个时代,因为你不仅仅是接收信息,你也在发推文。尽管你的配偶肯定会告诉你不要在家发推文。那是不对的。

View/Hide Original English

Or reading papers where you're on a receiving end but not providing anything in return. So it was a centralized information uh era that started you know uh with modernity and and you realize you should see the families eating their dinner in front of the TV set. Basically you're receiving information whereas organically in the past the way we dealt with information was by trading it. It's like Twitter. You you you give information, you receive information. So you go to the barber, someone gives you information, and then you go to buy fish, you give the fish monger information, and then rumors start going. So, and now we're close to that period because you're not just receiving stuff, you're also tweeting, you know, so although your spouse, I'm sure, tells you not to tweet from home. That's wrong.

主持人: 是的,没错。我想这是真的。当我们试图引起乔(Joe Weisenthal)的注意时,我们给他发私信,他什么都不回复。

View/Hide Original English

That's correct. That's correct. Okay. I guess it's true. When we're trying to get Joe's attention, we send a DM doesn't respond to anything.

纳西姆·塔勒布: 所以,我确定他正在发推文。所以你觉得你不仅仅是在接收噪音,你还在创造。

View/Hide Original English

So, I'm sure he's tweeting. So you're feeling you're not just receiving noise, but you're creating.

主持人: 所以我正在贡献。我通过贡献噪音而变得有用。谢谢你。非常肯定。

View/Hide Original English

So I'm contributing. I'm being useful by contributing to the noise. Thank you. Thank very validating.

社交媒体与公共形象

主持人: 等等,但您个人喜欢用Twitter吗?因为我读过您的一些推文,有时您看起来有点生气。

View/Hide Original English

Wait, but do you personally enjoy being on Twitter? Because I read some of your tweets and uh you know sometimes you seem a little angry.

纳西姆·塔勒布: 不。如果我现在在你们所有人面前发推文,推文看起来会很生气,但我的脸——我发推文时经常咯咯地笑。

View/Hide Original English

No. So just a little if I were tweeting now in front of all of you. Yeah. The tweet would look angry but my face I'm often giggling when I'm tweeting.

主持人: 好的。

View/Hide Original English

All right.

纳西姆·塔勒布: 我经常咯咯地笑。所以,关键是要把你的公众形象和你的私人生活分开。

View/Hide Original English

I'm often giggling. So, the idea is to separate your your uh public persona from your private life.

主持人: 顺便说一句,在我们忘记之前,在你今晚离开之前,有人私信我,说:“请问纳西姆能不能把我从Twitter上解除屏蔽?”我总是收到这样的请求。这可能是最……在你离开之前提醒我一下。他看起来是个好人。他们都说:“哦,对不起。我喝了酒,或者我不知道。”

View/Hide Original English

By the way, before we forget, before you leave tonight, someone DM'd me and said, "Can you please ask Nim to unblock me on Twitter? I get these all the time. It's probably the most remind me before you leave. It's a seemed like a nice guy." And so, they all say, "Oh, sorry. I had a drink or I don't know."

纳西姆·塔勒布: 等等,我们应该这样做,因为比特币(Bitcoin)的原因,我使用了“链式屏蔽”(chain block: 一种在社交媒体上屏蔽某个用户及其所有关注者或互动者的策略)。不,当有人进行诽谤活动时,你就会链式屏蔽。所以,如果有人欺负你,你也会屏蔽他们的朋友。这在当时是可行的。

View/Hide Original English

Wait, we should actually because of Bitcoin because I chain blocked. No, when you have a smear campaign, you chain block. So the friends, if someone bullies you or pro, you you block their friends as well. Making it was possible at a time.

主持人: 等等,这里有多少人被纳西姆·塔勒布亲自屏蔽过?

View/Hide Original English

Wait, how many people here have been personally blocked by Nim Taleb?

纳西姆·塔勒布: 没那么多。没那么多。数量很少。不是因为……不,不,不。在一个纽约的随机房间里。我几年前就停止使用链式屏蔽器了。

View/Hide Original English

Not that many. Not that many. It's a small number. It's not because No, no, no. a random room in New York. I stopped I stopped a couple of years ago from using the chain blocker.

主持人: 是的。

View/Hide Original English

Yeah.

纳西姆·塔勒布: 一方面是因为它有很多第二类错误,就是假阳性。另一方面是因为当埃隆(Elon Musk)接管Twitter时,他禁止了这些机器人。

View/Hide Original English

One because it had a lot of type two error that the you know the false positives and uh the other reason is uh because when Elon took Twitter he banned these uh bots.

主持人: 是的。

View/Hide Original English

Yeah.

纳西姆·塔勒布: 所以它们不能再运作了。你必须手动操作。

View/Hide Original English

So so they can't operate anymore. You got to do it manually.

主持人: 哦,就像你用来屏蔽某人及其朋友、朋友的朋友,以及所有这些的第三方应用程序?

View/Hide Original English

Oh like the third party apps that you Yeah. Yeah. Exactly. They could use to block someone their friends the friends of their friends. a friend and friends of the friends and all of that to yourself.

市场波动与特朗普的关税政策

主持人: 您是否惊讶,在一个似乎日复一日地出现令人难以置信的头条新闻、多场战争正在进行、更不用说贸易战以及所有其他事情(比如狗狗币等等)的年份里,市场并没有比现在更疯狂?

View/Hide Original English

Are you surprised that in a year of just like unbelievable headlines seemingly day after day multiple wars going on not to mention the trade war and all of that everything else Doge etc that the markets are not crazier than they are

纳西姆·塔勒布: 让我来写一条推文,也许我会发布。关于特朗普一世(Trump 1: 指特朗普第一次担任总统),他的敌人从字面上理解了他的话,而他的朋友则从隐喻上理解。特朗普二世(Trump 2: 指特朗普第二次竞选总统),他的敌人从隐喻上理解他的话,而他的朋友则从字面上理解。

View/Hide Original English

let me compose a tweet that maybe I'll post is uh for Trump one okay Trump one was taken uh literally by his enemies by his uh and metaphorically by his friends. Okay. Trump too is taken metaphorically by his enemies and literally by his friends.

主持人: 解释一下。

View/Hide Original English

Explain.

纳西姆·塔勒布: 所以他现在说的任何话,他都差不多会付诸实施。你相信他会开始征收这些关税吗?它们毫无意义。我的意思是,它们在宾夕法尼亚州(Pennsylvania)赢得选举可能是有意义的,但我的意思是,这并不是你真正会做的事情。结果他真的这么做了。这不仅仅是一个模糊的口头比喻,它是真实的。他想要关税。所以也许他想摧毁美国经济。也许这就是他的愿望。而且,你可能会造成一些损害。

View/Hide Original English

So whatever he's saying now, he's pretty much doing I did you believe that he was going to start these tariffs. They make no sense. I mean it make sense to get elected in Pennsylvania, but but I mean it's not a kind of thing you do really. And and it turned out he he meant it. It was not just, you know, uh, a vague, uh, it's really an oral metaphor. It was real. He wants tariffs. So maybe he wants to destroy the American economy. Maybe that's his wish. And, uh, and you could probably put a dent.

主持人: 然而,这并没有奏效,因为股市处于历史高点。

View/Hide Original English

And yet, but it's not work where stock market's at alltime high.

纳西姆·塔勒布: 抱歉。股市……首先,你必须把美国公司的健康状况分开。

View/Hide Original English

Sorry. The stock market is first of all, you have to separate the health of American companies.

主持人: 我明白。

View/Hide Original English

No, I get that.

纳西姆·塔勒布: 那些去Stop and Shop或你们当地的商店(不是Whole Foods,你们这些人都去Whole Foods,但普通人去Costco之类的)购物的美国人的收入,然后你看看你的账单,对吧?几乎所有东西的账单都上涨了,而他们的收入却没有。即将到来的减税政策对那些不去豆腐店购物的人没有帮助,因为穷人反正不用交税,所以他们不会从中受益。所以,这些关税政策是疯狂的。我能理解我们需要保护制药业,我们在这方面有一些战略利益。好的,你保护这个行业,你希望确保你不依赖中国来获取其他东西,但这是一种疯狂,试图在美国失业率只有4%左右的情况下,从高利润(你们都是高利润人群)转向低利润行业。

View/Hide Original English

your the income of the American who went to uh Stop and Shop or what's this thing in your area? Not Whole Foods. You know, you guys go to Whole Food, but normal people go to Costco, whatever. Then you look at your bill, right? And and the bill went up practically for everything and their income did not. and tax breaks to come are not going to help those who don't shop at tofu because it's the the the poor people you don't pay taxes anyway so so they're not going to get break from that so the idea is there's a lunacy in in these tariffs I can understand that we need to protect pharma we have some strategic interest in this okay you protect the industry you want to make sure you don't depend on China for other things but it it's a lunacy to try to switch with 4% unemployment in America plus or minus from high margin you guys are all hard margin all right to low margin right high margin audience yeah we have a high margin audience to low margin right occupations right

主持人: 是的,我们有一个高利润的受众。

View/Hide Original English

yeah we have a high margin audience to low margin right occupations right

纳西姆·塔勒布: 所以现在我们要生产袜子,你能想象吗?高利润的行业,比如制作电影,我们要去生产袜子。而且,对贸易会计中很多事情的整个过程也存在误解。他们说:“哦,他们正在敲诈我们。”我的意思是,我是一个牙医,我去买面包,这难道是在敲诈我吗?我应该自己做面包,然后总统,也许面包师应该成为牙医。所以,整个想法是不成立的。而且,你知道,如果一个人不是很聪明或不是很熟练,你就能发现。这就像套利者。你们是金融界的听众,我们称之为“自相交易”(trading against themselves)。他们进行一系列交易,最终形成一个循环,但却是亏损的。他们以前称之为“德州交易”(Texas trades),但我认为德克萨斯州(Texas)受到了不公平的诽谤。是的。一般来说,德州交易。其中之一是“德州对冲”(Texas Hedge)。所以,举个例子,他们对你用来在纽约地下室组装电脑的零部件征收关税。但是如果你购买Apple产品,就没有关税。尽管那是在海外制造的,所有东西都是在海外制造的。所以,这是一个不一致的地方。

View/Hide Original English

so now we're going to make socks can you imagine the high margin so making u making films we're going to make socks and and then also misperception of the whole process of a lot of things in um in in basic uh you know uh trade accounting like uh they say oh they're rip they're ripping us off I mean I'm a dentist all right and I go buy my bread it's ripping me off right I should make my own bread and and then the president probably the baker should be a dentist so the the whole the whole idea is not is it doesn't stand on and plus they have You you know if someone is not very intelligent or not very skilled and you can detect that at at it's like arbitragees. You guys are from financial audience and we call that trading against themselves. They do a series of trades that end up being closing a loop being circular but was a loss. All right. They used to call that Texas trades but I think that the state of Texas has been uh unfairly you know defamed. Yeah. Know Texas trades in general. One of them is Texas Hedge, right? So the So for example, they have tariffs on components that you would use to build a computer in your basement in New York. Okay? But if you bought an Apple product, then there's no tariff. Although that's made in over everything is made overseas, manufactured. Okay. So this is an inconsistency.

主持人: 所以有很多类似的不一致之处。

View/Hide Original English

So there are plenty like that. Sure.

纳西姆·塔勒布: 还有那个谁?商务部长。他绝对应该被雇去演喜剧,因为他首先说他想要……他没有意识到这种不一致。他说:“哦,我们将从关税中筹集到这么多钱。”然后当你问他:“你的意思是经济不会通过替代来适应你的关税吗?”他没有想过这个问题。他希望我们生产……对香蕉征收关税,所以我们会有替代品。或者他谈到葡萄酒。他说:“哦,人们会购买美国葡萄酒。”但是如果法国葡萄酒的价格上涨了呢?

View/Hide Original English

And there's also what's his name? Um the secretary of treasury is like secretary not treasury secretary of commerce is yeah he he he definitely someone should hire him for comedy because he was saying first of all he wants he he he he doesn't the inconsistency he didn't realize he said oh we're going to raise so much money from tariffs and and and then when you ask him you mean that the economy will not adapt to your tariffs by by replacement he didn't think about it and and and he wants us to produce to pay tariffs on bananas so we're gonna have substitutes or he he spoke about wine he said oh people will buy American wine but what happens if French the price of French wine goes up okay

主持人: 好的。

View/Hide Original English

okay

纳西姆·塔勒布: 有一种东西叫做“替代”(substitution)。我不知道欧洲人是否这样做,他们在高中就教经济学,我的意思是,他们教孩子们替代。所以这是基本的。我的意思是,我说特朗普应该雇佣……如果你能找到一些有技能的人。

View/Hide Original English

there's something called substitution I don't know if people do that in Europe they teach high school economics I mean for ch children where they teach substitution right so it's elementary me I mean I'm saying that he Trump should have hired If you if you could find people who have some skills. All right.

主持人: 我迫不及待地想发展我的技能,自己种植香蕉。香蕉艺术。抱歉,我今晚说不出话来。好的。我本来想问,您总是宣扬“切肤之痛”(skin in the game: 指个人利益与决策结果紧密相连,从而促使更负责任的行为)。

View/Hide Original English

I can't wait to develop my skills growing my own bananas. Banana arti. Sorry, I can't talk tonight. Okay. I was going to ask, you always preach skin in the game.

Universa Investments的策略与“反脆弱”概念

主持人: 嗯,不像我们记者。所以,我必须问,您仍然是Universa的顾问。那里发生了什么?您的回报如何?告诉我们所有数字。

View/Hide Original English

Um unlike us journalists. So, I got to ask, you're still an adviser to Universa. What's been going on there? What are your returns like? Give us all the numbers.

纳西姆·塔勒布: 好的。不,我……这里不是讨论数字的地方。你不会得到所有信息,但你可以了解我们现在所采用的一般方法和理念,以一种压缩的形式描述我们做什么以及如何做。我们可以肯定地说,像往常一样,我们所做的一切都奏效了。从某种意义上说,这个想法是,你必须看对冲的收益,你必须看被对冲的投资组合的收益,因为这有点像你为你的房子买了保险,对吧?你看到的是“房子加保险”的整体,你不会把保险看作是一个可交易的东西,今天我没有保险,明天我会有,或者它如何盈利?你看到的是一个整体。好的,保险让你能买更大的房子,因为你知道在那种情况下你的总风险更低。

View/Hide Original English

Okay. No, I so this is not the place to discuss numbers. Uh you won't get all right but you can get a general approach and philosophy uh that I have now to describe in in a in a format compressed format of what we do and how we do it. Um we can safely say that as usual uh whatever we're doing worked okay in a sense that the idea the idea let me the idea the idea is that you got to look at the return of that hedge you got to return the portfolio that was hedged because sort of like when you when you have an insurance on your house all right you look at the package house plus insurance you don't look at insurance as a tradable think today I'm not going to have insurance, tomorrow I'll have or how is that paying off? You look at the package. Okay, insurance allows you to buy a bigger house because you know your your total risk is lower in the case of stuff like that.

纳西姆·塔勒布: 所以,情况是一样的,股市上涨了,这意味着不仅对冲做得不错,而且它甚至没有被需要。所以,你就像在你的保险上赚钱。所以,这个故事继续下去,我们现在已经这样做了……时间过得真快。我们现在是2025年,25减去……哦,很多年了,对吧?所以我们已经这样做了18年,直接与Universa合作了18、19年,当然之前也有过迭代。情况就是这样,我们一秒钟都没有改变策略,我们也不会改变策略。所以基本上我们所做的就是同样的事情,只是规模越来越大。

View/Hide Original English

So, it's the same situation and and the stock market rallied which which mean that not only did the hedge do okay, but it wasn't needed. So, you're like making money on your insurance. So netn net that story continued and we've been doing it now for uh time flies. Uh we're in 2025 25 minus uh oh it's a lot right so we've done it for 18 years 18 19 years directly was universal and then before of course an iteration before and it is that it's the same story we didn't change strategy for a second and uh we will not change strategy so basically that's what we do is the same thing it's just it's getting bigger that's it

主持人: 嗯,等等,现在有更多的波动事件。您完全不适应或不考虑这些吗?

View/Hide Original English

well wait there are a lot more volatility events nowadays. Do you not adapt to that at all or take that?

纳西姆·塔勒布: 嗯,让我告诉你,如果你看净值,首先,我不会把波动性看作是波动性。在我的技术工作中,Universa不看波动性。你看到的是,例如,你可以有一个“尾部事件”(tail event: 指概率分布中极端事件的发生),然后你可以有常规波动性。所以很多人被常规波动性所困扰,通常他们所说的常规波动性——我学会了这种商业语言——是当市场下跌时,在过去他们亏钱时,他们会说:“好的。所有市场都在波动。”波动性并不意味着它正在上涨。波动性不是一个绝对的平均偏差。波动性是负回报。所以,很多对波动性的看法都是通过……我的意思是,你们记者这个职业当然非常重要,你可以揭露坏事等等。但通常……

View/Hide Original English

Well, let me tell you if you look net net first of all I don't look at volatility as volatility okay in in my technical work and universal doesn't look at vol you look at for example you can have a tail event and then you can have or you can have regular volatility so a lot of people are overall by regular volatility and typically what they call regular volatility I learned the linguistics of of that business is when the market goes down they don't in the old days when they're losing money they would Okay. All the markets are volatile. Volatile doesn't mean it's going up. Volatile is not an absolute uh mean deviation. Volatile is negative return. All right. So, so a lot of perception of things of volatility by exact. I mean your profession journalist is of course very important that way you can reveal uh uh bad stuff when it's made and things like that. But but often

主持人: 纳西姆刚才说了记者行业的好话吗?

View/Hide Original English

did Nim just say something nice about journalism?

纳西姆·塔勒布: 是的,是的。不,不,有很多事情。这是一个重要的使命。但是,但是,但是很多时候,规模并不完全匹配。例如,新闻界的人,我在《随机漫步的傻瓜》(Fooled by Randomness)中写过这一点,报纸应该有……现在我们没有报纸了,但你明白我的意思,在股市崩盘的日子里,或者在过去几周,报纸应该那么大,而其他时候应该只有半页,但它们长度都一样。

View/Hide Original English

Yeah. Yeah. No, no, there are a lot of things. It's an important mission. uh but but but very often uh there's the scaling doesn't uh doesn't quite match like for example people in journalism and this I wrote about in fooled by randomness you should have newspapers or they say length of newspapers now we don't have newspaper but you understand what I mean there should be on days like the stock market crash or on last couple of weeks newspapers should be that big and the rest of the time should be half a page but they have the same length

纳西姆·塔勒布: 好的。所以这就是新闻业的规模问题。换句话说,你有14分半钟的新闻,加上中间的Bloomberg广告。所以,我的意思是,新闻快报应该根据事件而变化。你明白我的意思吗?市场波动也是如此。所以我不认为我们正在经历真正的波动性,与可能发生的情况以及我们所见的爆炸性市场相比。

View/Hide Original English

All right. So that's the scaling problem in journalism. In other words, you have the news 14 and a half minutes plus, you know, of course the Bloomberg uh ad in the middle. So so the I mean that that news bulletin should be variable with with with with the events. You see the idea? So same thing with market movement. So I don't think that we are experiencing real volatility compared to what could have happened and what we have seen with explosive uh markets. Yes.

主持人: 所以,如前所述,多场战争正在进行。我们经历了新冠疫情冲击,经历了通货膨胀冲击,政治格局正在发生巨大变化,包括就在纽约市。在您看来,是否有潜在的原因导致我们感觉大事正在发生?

View/Hide Original English

So, as mentioned, multiple wars going on. Uh we had the COVID shock, we had the inflation shock, we have massive changes happening in the political landscape including uh right here in New York City. Is there an underlying reason in your view why it feels as though big things are happening?

纳西姆·塔勒布: 不,我的全部观点是,要回到“尾部”(tail: 指概率分布的极端部分),回到我们所说的“肥尾”(fat tail: 指概率分布中极端事件发生频率高于正态分布的现象)。肥尾意味着最少数量的事件解释了最大数量的偏差。例如,如果你有一千人,存在不平等,那么一个人将拥有大部分财富。同样,少数历史性日子包含了大部分信息。

View/Hide Original English

No my whole point is that what to go back to is go back to tail to to what we call about fat tail. Fat tales means the smallest number of event explains the largest number of uh deviations. For example, if you take a thousand people and you have inequality, one person will have most of the money. Likewise, few historical days have most of the information.

主持人: 嗯。

View/Hide Original English

Mh.

纳西姆·塔勒布: 同样如此。所以这完全是正常的。关键是你无法提前预测你何时会遇到这些日子,或者你会有它的结构,尽管它非常非常稳定。事情往往遵循“幂律”(power law: 一种数学关系,其中一个量随另一个量的幂次变化)。

View/Hide Original English

Like likewise. So this is entirely normal. The point is you can't you couldn't predict ahead of time that you're going to have when you're going to have these days or you're going to have the structure of it is though very very uh uh stable. It is things follow tend to follow a power law. So go ahead.

主持人: 哦,我将问一个非常基本的问题,我相信您总是被问到,但我们都非常想知道您的答案。嗯,根据定义,“黑天鹅”(black swans: 指发生概率极低,但一旦发生就会产生巨大影响的事件,且事后看来似乎可预测)是不可预测的,也是不可能预测的。但是您在地平线上看到了哪些黑天鹅?

View/Hide Original English

Oh I'm going to ask a very basic question that I'm sure you get asked all the time but we are all nevertheless very interested in your answer. Um, by definition, black swans, I guess, are unpredictable um, and impossible to forecast. But what black swans do you see on the horizon?

纳西姆·塔勒布: 好的,所以这……让我重新措辞。让我重新措辞。好的,有一种东西叫做“灰天鹅”(gray swans: 指那些虽然发生概率低但并非完全不可预测,且影响巨大的事件)。所以大流行病就是灰天鹅,或者你知道,灰天鹅意味着那些具有以下特征的事件:极少数事件决定了总效应的很大一部分,比如少数战争导致了大多数人的死亡,类似大流行病的事情。所以有灰天鹅,你可以说它们有结构。你无法提前预测它们。你不知道。但是我们所做的是,你可以判断一个环境是否脆弱。在一个脆弱的环境中,你可以说:“好的,如果发生冲击,这很容易崩溃。”就像2007年,我们知道银行是脆弱的。

View/Hide Original English

Okay, so this let me rephrase. Let me rephrase it. Okay, there's something called gray swans. All right. So great pandemics were gray swans or or you know gray swans means events that have these characteristics of very small number of events determine large part of the total effect like small a small number of events uh small number of wars that killed most of people stuff like that pandemics. So there's grace sworns and you can say they have a structure. You predict them ahead of time. You don't know. Okay. But what we do is you can figure out if an environment is fragile or not. And in a fragile environments you can say okay this is prone to break if there's a shock. Like in 2007 we knew that banks were fragile.

纳西姆·塔勒布: 为什么?它们对波动性是净空头(net short volatility: 指从市场波动中获利,但如果波动性大幅增加则会亏损的头寸)。这有点像我在《反脆弱》(Antifragile: 纳西姆·塔勒布的著作,探讨如何从混乱和不确定性中受益)中关于脆弱性的工作。为了回答你的问题,我写了《反脆弱》,这本书本身就成了一个巨著,对吧?但核心思想是弄清楚什么会从冲击中产生连锁反应。好的,正如我在《黑天鹅》(The Black Swan: 纳西姆·塔勒布的著作,探讨不可预测事件及其影响)中写的,说哪种颜色的卡车会压垮一座脆弱的桥梁是愚蠢的。但是说这座桥梁是脆弱的,总有一天会断裂,不要过桥,或者邀请你的敌人过桥,这并不愚蠢。

View/Hide Original English

Why? They were net short volatility. That's sort of my fragility work in antifragile. To answer your question, I wrote antifragile, which on its own became a monster, right? But but the the whole idea is to figure out what can be uh have cascading effects from shocks. Okay, as I wrote to the black swan, it's foolish to say what color truck is going to break a fragile bridge. Okay, but it is not foolish to say this bridge is fragile. It's going to break one day. Don't cross it. Don't don't or or or or invite your enemies to you know

主持人: 好的。您现在看到了哪些脆弱领域?

Okay. Okay. What what areas of fragility do you see right now?

脆弱性领域:赤字与政治系统

纳西姆·塔勒布: 所以第一个我正在学习。好的。所以第一个是,我们有一个……我不知道你是否意识到,也许人们还没有意识到,我们有赤字。

So the first one I'm learning. Yeah. The fir Okay. So the first Yeah. The the first one is we have a I don't know if you're aware of it. Maybe people aren't aware yet that I don't know if we know we have a deficit.

主持人: 哦,我听说过这个。而且你知道你必须借钱来支付利息,你知道,你以前的债务的利息支出。在4%以上,4%到5%的利率下,这是很重要的,意味着你可能会有“滚雪球效应”(snowballing effect: 指问题或债务像滚雪球一样越滚越大)。你不得不借越来越多的钱,而且你知道他们并没有真正解决预算问题,除了口头上说:“嘿,我们要解决预算问题。”你知道,这都是老一套。不幸的是,政治体系的结构正在把我们推向那里。好的。所以,这是脆弱性的一个来源,一个主要的脆弱性来源。好的。政治体系不适应这种事情。所以,在西方世界发生的事情,不仅仅是美国的情况。这是整个西方世界的情况,因为你必须像我在《反脆弱》中描述的那样看待它。想想一条S型曲线S-curve: 描述事物发展过程的曲线,通常分为缓慢增长、快速增长和饱和三个阶段)。

Oh, I heard about this. And you know that that you have to borrow, you know, to pay for the interest rates for the interest uh uh ex you know the the uh the the debt that you've had before. And at four north of 4% interest rates, four to 5% interest rate, this is significant means you can have a snowballing effect. You had to borrow more and more and you know that they're not fixing the budget problem except verbally. Hey, we're going to fix the budget. You know, it's all the same story. Uh the structure of the political system unfortunately is driving us there. Okay. So, this is one source of fragility, one main source of fragility. Okay. That the political system is not adapted to that kind of thing. So, what happened in the western world, it's not just a case of United States. It's a case of the western world because you got to look at it as I describe in antifragiles. Think of an S-curve

西方经济增长的结构性衰退

纳西姆·塔勒布: 就像中国可以实现快速增长,因为他们把人们从风景优美的乡村拉出来,把他们安置在公寓楼里,这可能对人们来说并不愉快,你知道,住在盒子里,但这产生了巨大的经济增长。好的。所以很多人都在所谓的“发展规模”上上升。你处于S型曲线的“凸性部分”(convex part of the S-curve: 指S型曲线中增长加速的阶段)。好的。西方处于S型曲线的“凹性部分”(concave part of the S-curve: 指S型曲线中增长减速的阶段)。

like China can have rapid growth because they're pulling people out of their beautifully landscaped countryside to pull them in apartment blocks that maybe it's not pleasant for for the people, you know, to to live in in boxes, but that generates a huge amount of economic growth. Okay. So, a lot of people going up the so-called development scale. You're you're on the convex part of the S-curve. Okay. The west is on a concave part of the escort.

纳西姆·塔勒布: 这意味着你拥有两辆车……除了纽约人,纽约人住在像中世纪穷人一样的小盒子里,但在纽约市以外的真正地方,大多数人都有两车位的车库之类的。所以你无法增长,你没有穷人,所以你必须从萨尔瓦多(El Salvador)、巴拿马(Panama)等地进口他们,很多人你没有穷人。所以,你不需要创造那种东西,甚至现在你也不想要他们了。你不想……你不想每个人。所以,他们有一个问题,那就是美国的增长在结构上正在下降。

So which means that you have two car most except New York New Yorkers live in small boxes like like like uh poor people in middle ages but outside New York City in a real most people have two car garages stuff like that. So you you you we can't you can't grow right and you don't have poor people so you have to import them from El Salvador Panama a lot of people you don't have poor people. So, so you don't to create that kind of thing and and and even and now you don't want them anymore. You don't they don't want you don't want everybody, you know. So, so they have a problem that growth in America is structurally declining.

主持人: 是的。

View/Hide Original English

Yeah.

纳西姆·塔勒布: 同时,债务负担在结构上不断增加。你看到了这种分歧,这适用于其他发达国家,因为你发展了,你到达了目的地。你为什么还在借钱?问题是大多数国家在已经富裕的时候倾向于借钱,当他们不再需要的时候。就像人们,看看华尔街(Wall Street)的人。这些人都在华尔街。他们现在可能已经很富有了,但仍然借了很多钱,对吧?而穷人却不借钱。所以这是一个大问题。这是第一个问题。

View/Hide Original English

Well, at the same time, the debt burden is structurally increasing. You see that diversion and that applies to the rest of the developer because you develop, you're arriving to destination. Why are you still borrowing? The problem is most countries tend to borrow when they're already rich, when they don't need it anymore. Just like people, see like people on Wall Street. These people are on Wall Street. They probably borrow a lot now already rich. All right? Whereas poor people don't borrow. So that's a big problem. That's number one problem.

全球力量平衡的转变

纳西姆·塔勒布: 第二个问题是中国在全球GDP中所占的份额越来越大。所以你会认为地缘政治不会再像以前一样了。你不想活在错误的世纪里。你以为你活在这个世纪,但你以为你活在另一个世纪。

View/Hide Original English

The second one is China is representing a larger larger share of GDP of the world. And so you're going to think that geopolitics aren't going to be the same. And you don't want to live, you know, in the wrong century. Think you're living in this century, think you're in a different century.

主持人: 好的,纳西姆。非常感谢您。
