TIP 047: THE BLACK SWAN

W/ PRESTON, STIG, & HARI

28 July 2015

In this episode, Preston and Stig discuss the best-selling book, The Black Swan. This book was highly recommended by billionaire Jeff Bezos.
In the book, the author, Nassim Taleb, thoroughly discusses the mistakes that many people make by thinking the world is normally distributed. In fact, Taleb makes the case that most systems are not normally distributed and provides examples of how these systems can drastically impact the world.

All right, how’s everybody doing out there? This is Preston Pysh. I’m your host for The Investor’s Podcast. And as usual, I’m accompanied by my co-host, Stig Brodersen, out in Denmark.

And today, we’re going to sound a lot better than we usually do, because we have a special guest with you. And his name is Hari Ramachandra. Everybody knows Hari, from our Mastermind Group. He’s always that smart guy that we bring on the show to cover our weaknesses of not knowing what we’re actually talking about at times. And Hari comes from bitsbusiness.com. And the book that we’re going to be talking about this week is a really, really popular book. And this was one of his favorite books. And so, it was a very easy decision to bring him on the show to talk about some of the thoughts that he had on it along with Stig and I as we read this book. And the name of the book is “The Black Swan.” And the subtitle is The Impact of the Highly Probable and this was written by Nassim Nicholas Table‎.

This book is really been one of those books that a lot of different billionaires are talking about specifically Jeff Bezos, who was a huge proponent of this book. Bezos made this a mandatory reading for some time at Amazon for a lot of the executives there. Howard Marks endorses this book very heavily. You have Mohnish Pabrai and Guy Spier, I know that they’re fans of the book. And I’m sure there’s plenty more out there that really this book has had a huge impact on the way that they see markets, the way they see the world, and the way that it operates. And so that’s what we’re going to be talking about today. And it’s really exciting, Hari, obviously some of my joking comments there. But we really do mean it. You add so much value to the podcast when you come on. So it’s awesome to have you with us today.

Hari Ramachandra  02:32

Hey, Preston, thanks for having me. As you mentioned, this is one of my favorite books. And I’m glad to be here talking about this book with you guys.

Preston Pysh  02:42

Always fun, buddy. So let’s go ahead and jump into this one. And let’s just go ahead and start talking about the overall theme of the book. And this is what I took away and I want you guys to shoot some holes. Maybe I didn’t understand it nearly as well as you guys. But the main thing that I took away from this is that the distribution when you talk about statistics and for anybody who doesn’t know Nassim Taleb‎ and what he’s great at, he’s great at statistics. And what he’s talking about here in the book is that distributions are not normal. And I think that whenever people think about statistics, especially in an academic sense, they think about the distribution in the bell curve. And they think that when you model different systems, whether it’s the stock market and the different points on that, or whatever the model might be, everyone thinks of things in the normal distribution. And I think Nassim Taleb would probably take on the approach that it’s never a normal distribution, and it’s slightly skewed. And that because of that, you get these extreme results that can sometimes happen.

And he uses the metaphor of the Black Swan. Everyone thinks that all swans are white, and then you see the Black Swan and then that one event can have such a catastrophic impact on the direction of the future and the way that things emerge. And so that’s really the takeaway that I had. And I’m really curious to hear what Stig and Hari have to say about that idea. Or maybe you guys want to add to some other themes that you really captured from the book. So I’m going to first throw it over to Stig, and then we’ll go to Hari.

Stig Brodersen  04:12

I’ll just continue on what Preston said about the normal distribution because someone might be sitting out there and saying, “What is this normal distribution? What are we talking about?” We’re talking about statistics, and normal distribution that’s basically just that we can more or less rely on the past. We can rely on the past in the sense that we have some occurrences that happen very, very often. And then we have something that happens very rarely. And I think when you’re talking about Black Swans, it’s something that can happen not often, but it’s definitely something that is not very, very rare. And it’s something that has a huge, huge impact when it does happen. So it’s not like the normal distribution, you cannot just plot it in, like the probability of that. Not at all when talking about Black Swans.

And the way that he is displaying that he’s doing that very neatly with an example. So the way he explains this is he’s telling me a story about a turkey, which was being fed for a thousand days. Now for that turkey, the very next day is very predictable. But well, I guess we all know what happens to a turkey around Thanksgiving, right?

So he’s saying, well, Black Swans, they’re relative. It might be more relevant to look at the butcher and talk about what is very common for him and what he can expect the next day. So he’s having all these very, very neat examples of you can really rely on the past, and he’s saying best, the past irrelevant, and the worst, it can be catastrophic. So I guess that was my main takeaway from that. I don’t know about you, Hari. I know that you have read this book multiple times. So I’m really curious to hear what would you say?

Hari Ramachandra  05:52

I agree with both you and Preston. For me, the main message of this book is that we humans are prone to be overconfident. And as we were discussing before the show, ironically, the tone of the author in the book sounds a bit overconfident. But his message is very clear. And this tendency to be overconfident makes us take on risks that can be very harmful, and also makes us think we can predict and control our future. Whereas the world today is a complex system. And as you might have read in the book, he makes it very clear that in a complex system, it’s not only difficult to predict future events, but it’s almost impossible. And that is the problem of induction.

According to Nassim, in the book, the problem of induction is how can yo.u know the properties of the infinite unknown based on the properties of the finite unknown, which goes back to what you and Preston were talking about, which is, using a gaussian or a bell curve to predict a complex system, the future events that can happen.
