Bestselling author Nassim Nicholas Taleb continues his exploration of randomness in his fascinating new book, The Black Swan, in which he examines the influence of highly improbable and unpredictable events that have massive impact. Engaging and enlightening, The Black Swan is a book that may change the way you think about the world, a book that Chris Anderson calls, "a delightful romp through history, economics, and the frailties of human nature." See Anderson's entire guest review below.
Guest Reviewer: Chris Anderson
 Chris Anderson is editor-in-chief of Wired magazine and the author of The Long Tail: Why the Future of Business Is Selling Less of More.
Four hundred years ago, Francis Bacon warned that our minds are wired to deceive us. "Beware the fallacies into which undisciplined thinkers most easily fall--they are the real distorting prisms of human nature." Chief among them: "Assuming more order than exists in chaotic nature." Now consider the typical stock market report: "Today investors bid shares down out of concern over Iranian oil production." Sigh. We're still doing it.
Our brains are wired for narrative, not statistical uncertainty. And so we tell ourselves simple stories to explain complex thing we don't--and, most importantly, can't--know. The truth is that we have no idea why stock markets go up or down on any given day, and whatever reason we give is sure to be grossly simplified, if not flat out wrong.
Nassim Nicholas Taleb first made this argument in Fooled by Randomness, an engaging look at the history and reasons for our predilection for self-deception when it comes to statistics. Now, in The Black Swan: the Impact of the Highly Improbable, he focuses on that most dismal of sciences, predicting the future. Forecasting is not just at the heart of Wall Street, but it's something each of us does every time we make an insurance payment or strap on a seat belt.
The problem, Nassim explains, is that we place too much weight on the odds that past events will repeat (diligently trying to follow the path of the "millionaire next door," when unrepeatable chance is a better explanation). Instead, the really important events are rare and unpredictable. He calls them Black Swans, which is a reference to a 17th century philosophical thought experiment. In Europe all anyone had ever seen were white swans; indeed, "all swans are white" had long been used as the standard example of a scientific truth. So what was the chance of seeing a black one? Impossible to calculate, or at least they were until 1697, when explorers found Cygnus atratus in Australia.
Nassim argues that most of the really big events in our world are rare and unpredictable, and thus trying to extract generalizable stories to explain them may be emotionally satisfying, but it's practically useless. September 11th is one such example, and stock market crashes are another. Or, as he puts it, "History does not crawl, it jumps." Our assumptions grow out of the bell-curve predictability of what he calls "Mediocristan," while our world is really shaped by the wild powerlaw swings of "Extremistan."
In full disclosure, I'm a long admirer of Taleb's work and a few of my comments on drafts found their way into the book. I, too, look at the world through the powerlaw lens, and I too find that it reveals how many of our assumptions are wrong. But Taleb takes this to a new level with a delightful romp through history, economics, and the frailties of human nature. --Chris Anderson
Product Description
A black swan is a highly improbable event with three principal characteristics: It is unpredictable; it carries a massive impact; and, after the fact, we concoct an explanation that makes it appear less random, and more predictable, than it was. The astonishing success of Google was a black swan; so was 9/11. For Nassim Nicholas Taleb, black swans underlie almost everything about our world, from the rise of religions to events in our own personal lives.
Why do we not acknowledge the phenomenon of black swans until after they occur? Part of the answer, according to Taleb, is that humans are hardwired to learn specifics when they should be focused on generalities. We concentrate on things we already know and time and time again fail to take into consideration what we don’t know. We are, therefore, unable to truly estimate opportunities, too vulnerable to the impulse to simplify, narrate, and categorize, and not open enough to rewarding those who can imagine the “impossible.”
For years, Taleb has studied how we fool ourselves into thinking we know more than we actually do. We restrict our thinking to the irrelevant and inconsequential, while large events continue to surprise us and shape our world. Now, in this revelatory book, Taleb explains everything we know about what we don’t know. He offers surprisingly simple tricks for dealing with black swans and benefiting from them.
Elegant, startling, and universal in its applications The Black Swan will change the way you look at the world. Taleb is a vastly entertaining writer, with wit, irreverence, and unusual stories to tell. He has a polymathic command of subjects ranging from cognitive science to business to probability theory. The Black Swan is a landmark book–itself a black swan.

I bought the book because it is on best selling list, 4 stars and an interesting topic. However, quite a disappoinment. The black swan idea is quite refreshing but it is revealed completed in the first 20 pages. The rest are just repeative garbage.
I guess the author needs to make a living too and he is obviously paid by the number of pages. He simply turned a good article into a over-weight book.
 A good point, but Taleb overdoes it July 30, 2008

Nassim Taleb has written a very enthusiastic book, and provides some very tasteful food for thought. The problem is, Taleb himself is far too pleased with his own work.
Talebs confidence in his own ideas helps him write a book which is easy and fun to read. For an economist, interested in the philosophical background of the science, he offers plenty of very interesting references. I will most certainly dig more into the thoughts of Karl Popper and Benoit Mandelbrot.
But Taleb's confidence also helps him make several rather banal mistakes. His main adversary is the statistician Gauss and his normal distribution. Taleb is right that many economists and financial analysts rely far too much on normal distribution. But figure 7 on page 238 reveals that Taleb himself does not understand the concept pretty good: "..as your sample size increases, the observed average will present itself with less and less dispersion".
His confidence also makes Taleb jump to conclusions and make banal errors (the French Maginot Line, the main line of defence built in the 1930s, was not built where the Germans attacked France in World War One). Taleb even goes in his own primary trap: the confirmation bias. Every little thing happening by chance is counted as evidence of his Black Swan theory. But the story of penicillin is famous just because it was sensational, not because it is the normal way of making major medical breakthroughs.
It is probably not worthwhile to read this book, although there are grains of gold in it. The book is written in the spring of 2007, before subprime. In a footnote Taleb is writing about the risk of Fannie Mae: it "seems to be sitting on a barrel of dynamite." Touche!
 What we don't know can hurt us July 30, 2008

In 1997 my cousin worked on Wall Street and suggested to her colleagues that the office keep a rubber raft in the storage room in case the World Trade Center gets attacked again. She had to leave soon after that. They thought she was crazy. In fact, she was dead right. She had predicted what this book calls a "Black Swan"...something that most people cannot or will not predict.
One reason why I never bought real estate is because I have always been concerned about the effect of a nuclear bomb or nuclear reactor accident on said purchase. Most people would laugh at me for saying that. I hope that I am never correct, but I fear that somewhere, some day, real estate in a given area will approach zero value because of such a "black swan" event.
This is one of the best books you can read that describes how knowing what you don't know is more important than knowing what you know. It is interesting to know that the US Military takes this book and this author very seriously. Rumsfeld apparently quoted him several times when he was in office.

Very nice book, explains how the tail (outliers) in a bell curve is so imporant. Must read for financial engineers.

I can't comment on the science behind this book. I will say that - at least from this layman's perspective - Taleb offers magnitudes of insight on the ideas of unpredictability and randomness, and does a bang-up job of upsetting the status quo.
The book is centered on the concept of a Black Swan - an event that lies outside the narrow periphery of our knowledge, has an extreme impact or causes a major upset (whether it be cultural, financial, political, et al.), and is characterized by a rampant slew of retrospectives - all the media, the so-called "experts", and the authorities suddenly have the details on why it happened.
For instance, we are told by historians of the outbreak of WW2: "tensions were mounting" throughout Europe, and that there were "escalating crises" abound, but according to bond prices (which offer a good understanding of history, says Taleb), there was no sign of this to speak of! "One would suppose that people living through the beginning of WW2 had an inkling that something momentous was taking place. Not at all."
The idea of retrospective distortion and over-interpretation fascinates me. How people attempt to fit messy empirical reality into neatly organized interpretations! The problem with our predictions, and our retrospectives, is that they are often framed from a naive perspective that we live in a place called Mediocristan, a place where randomness is mild, or Type 01, when we really live in a place called Extremistan - where reality is characterized by wild, unpredictable events that completely upset the averages of the bell curve.
...We come out the other side mistrusting the arrogance of almost all predictions! What does bird poop have to do with one of the most fundamental physical theories? Do we think that our wars are "under-control", or do we consider the unpredictability of conflict - that a small conflict might someday spiral unpredictably out of control and result in the decimation of the entire human race!?! How has the Nobel Prize been exploited to sell methods of market-interpretation that are completely unscientific, yet universally accepted and completely institutionalized? We are treated to an interesting investigation of this arrogance which dominates so many fields of study and indeed, we find that it is an arrogance deeply embedded in our minds!
Despite the seemingly bleak picture, The Black Swan is great fun to read and offers tips ("be as hyper-conservative and as hyper-aggressive as you can!") on how to cope and perhaps even thrive in this chaotic, simmering soup we call Civilization.
If you are like me, you will enjoy reading about things like the narrative fallacy, confirmation bias, the ludic fallacy, the problem of induction, et al. My only criticism of book is it's repetition, but honestly - I hardly noticed.
