Fooled by Randomness: The Hidden Role of Chance in Life and in the Markets [Paperback]

Nassim Nicholas Taleb (Author)

Book Description

Release date: August 23, 2005

“[Taleb is] Wall Street’s principal dissident. . . . [Fooled By Randomness] is to conventional Wall Street wisdom approximately what Martin Luther’s ninety-nine theses were to the Catholic Church.”
–Malcolm Gladwell, The New Yorker

Finally in paperback, the word-of-mouth sensation that will change the way you think about the markets and the world.This book is about luck: more precisely how we perceive luck in our personal and professional experiences.

Set against the backdrop of the most conspicuous forum in which luck is mistaken for skill–the world of business–Fooled by Randomness is an irreverent, iconoclastic, eye-opening, and endlessly entertaining exploration of one of the least understood forces in all of our lives.

Editorial Reviews

Amazon.com Review

If the prescriptions for getting rich that are outlined in books such as The Millionaire Next Door and Rich Dad Poor Dad are successful enough to make the books bestsellers, then one must ask, Why aren't there more millionaires? In Fooled by Randomness, Nassim Nicholas Taleb, a professional trader and mathematics professor, examines what randomness means in business and in life and why human beings are so prone to mistake dumb luck for consummate skill. This eccentric and highly personal exploration of the nature of randomness meanders from the court of Croesus and trading rooms in New York and London to Russian roulette, Monte Carlo engines, and the philosophy of Karl Popper. Part of what makes this book so good is Taleb's ability to make seemingly arcane mathematical concepts (at least to this reviewer) entirely relevant in evaluating and understanding everything from the stock market to the success of those millionaires cited in the aforementioned bestsellers. Here's an articulate, wise, and humorous meditation on the nature of success and failure that anyone who wants a little more of the former would do well to consider. Highly recommended. --Harry C.

From Publishers Weekly

In this look at financial luck, hedge fund manager Taleb (Dynamic Hedging) addresses the apparently irrational movement of money markets around the world. Using his own investing experience and examples of others' successes and disappointments, he discusses theories like Monte Carlo math (easy; considered cheating by purists) and the concept of Russian roulette. Taleb tells interesting, well-wrought stories about individual behavior: "While Nero has succeeded beyond his wildest dreams, both personally and intellectually, he is starting to consider himself as having missed a chance somewhere." While serious investors and mathematics enthusiasts will be intrigued, readers looking for practical investment strategies will be disappointed by this rambling intellectual discourse. Tables. 40,000-copy first printing; $150,000 marketing budget.

More About the Author

Nassim Nicholas Taleb has devoted his life to problems of uncertainty, probability, and knowledge. He spent two decades as a trader before becoming a philosophical essayist and academic researcher. Although he now spends most of his time either working in intense seclusion in his study, or as a flâneur meditating in cafés across the planet, he is currently Distinguished Professor of Risk Engineering at New York University's Polytechnic Institute. His main subject matter is "decision making under opacity", that is, a map and a protocol on how we should live in a world we don't understand.

His works are grouped under the general title Incerto (latin for uncertainty), composed of a trilogy accessible in any order (Antifragile, The Black Swan, and Fooled by Randomness) plus two addenda: a book of philosophical aphorisms (The Bed of Procrustes) and a freely available Technical Companion. Taleb's books have been published in thirty-three languages.

Taleb believes that prizes, honorary degrees, awards, and ceremonialism debase knowledge by turning it into a spectator sport.

""Imagine someone with the erudition of Pico de la Mirandola, the skepticism of Montaigne, solid mathematical training, a restless globetrotter, polyglot, enjoyer of fine wines, specialist of financial derivatives, irrepressible reader, and irascible to the point of readily slapping a disciple." La Tribune (Paris)

3.0 out of 5 stars Good, But A Personal Memoir, Not a Treatise September 13, 2005

By Bradley A. Swope

Format:Hardcover

REVIEW: This book tends to elicit very strong opinions about its quality (both very good and very bad) so it is important to know which camp you are in before you purchase it or you may be very disappointed. I found that both the very bullish and the very bearish reviews have significant merit. On the plus side Taleb aggressively addresses a topic that many readers will be interested in - randomness in our daily lives. He discusses many important concepts that are not known or at least not very well understood by the general public and experts alike. These include: 1) that uncertainty and luck play a large role in the outcomes of human activities (much more than most people think); 2) that a correlation between two types of events does not necessarily mean that one causes the other; 3) that statistics and the rare random event are poorly understood by almost everyone; 4) that small differences in performance and ability can cause very large differences in the rewards or difficulties that people obtain in life; and 5) that humans are very irrational beings and are not very good at thinking probabilistically and understanding the probabilities of even everyday events rationally. All of these are important points that I commend Taleb for bringing to our attention.

However, there are significant drawbacks to this book, which to some readers will make the book significantly unenjoyable or even impossible to read. While it did not significantly bother me, Taleb does have an attitude or style which at times tends to the snobbish. The author repeatedly reminds readers that he is well traveled, is a "voracious" reader, pursues his exercise routines "assiduously", and is from upper class Mediterranean roots. Further, at some points in the book, he writes from a bitterness and contempt (which he admits) for journalists, economics, others in his profession, and generally those who are not "literate persons". In general, I would have preferred that Taleb left most of these personal issues out of the book and that he have written it with a little more rigor. But in fairness Taleb clearly warns the reader that his book is a personal memoir and not a treatise. Unfortunately, I believe this is mostly a cop-out to avoid addressing his critics on the merits. The book has the look and feel of a treatise, and I was hoping for a treatise, but it doesn't deliver.

STRENGTHS: Addresses an important topic not well understood and not written about enough; most people will benefit from a better understanding of the major concepts brought out in this book; the author is well read and not afraid to offend and pursue the material aggressively

WEAKNESSES: I hate to say it because I find the author likeable in many ways, but too much of the author's personality comes through and what it suggests to me is that he may have significant insecurities and passive aggressive issues that may even be pathological; many readers will have a hard time getting past the author's aggressive style or perceived "bad attitude", some readers may even see the book as political; the book is "a personal memoir and not a treatise" and thus lacks the rigor that many would expect; the author takes great pains to try to avoid addressing any substantial criticism (this is the first book I've read where the author feels the need to attack the credibility of Amazon reviewers calling them "unqualified" to comment on his book)

5.0 out of 5 stars Essential for understanding the workings of the world March 11, 2002

By A Customer

Format:Hardcover

Anyone who holds any doubts in regards to the validity of this book must read Edward Chancellor's 'Devil Take the Hindmost,' which provides a history of financial markets from the dawn of the Roman Empire up to now. After reading such a sweeping historical account, one sees the financial markets for exactly what they have always been: one vast bubble machine where people have even invested in, according to Chancellor, a company that refused to explain anything about what it did but simply assured the investors that it had a great idea for making money. Sounds rather similar to some of the dot coms in recent years. Through a compliation of both antecdotes and thoughts, Taleb provides an explanation as to why the markets work in this way, why so many fail to realize this, and how these issues are mirrored in our everyday lives. He addresses many issues that everyone should understand in order to view the world in a realistic manner. Evolution is not a one way road to nirvana but rather the process through which those adapted to the current situation fare better, and they may not be best adopted when things change. When judging the validity of any strategy in business or in life one must consider that the winners write the history books; you can only talk to survivors of war but that certainly doesn't mean that everyone survives it. When deducing anything from viewing a sample you must consider the forces that created that sample: should you consider yourself unintelligent because you're behind your classmates at a top law school? Are a good outcome and a good decision the same thing, and likewise for a bad outcome and a bad decision? And the list goes on.

While Taleb does not fully dive into this issue until later in the book, the primary conjecture of the piece is that human beings are psychologically prone to misinterpret random events. We need to explain things, whether it be in the social sciences, art and literature, or the natural sciences, so we find ways to explain them. Considering the infinite quantities of data at our disposal, no statistician denies that extremely powerful correlations will occur simply out of chance. Certain aspects of an author's life will be almost identical to passages in his or her novels, certains stocks will share perfect correlations, and we are creatures in need of explanation, and whole industries have been created to mine the data and tell us why things occur.

Prior to this book, Taleb had already written 'Dynamic Hedging,' considered by many, including myself, to be one of the best books ever written on exotic and vanilla options. That book is not for anyone who has not spent years studying (or preferably practicing) options, but in 'Fooled by Randomness' he illustrates his ideas in terms that anyone could understand. In 'Dynamic Hedging' he provides more insights into his trading strategies than he would have done had he been solely profit motivated, and likewise, as the boss of a fund that profits from other people's misconceptions of probability, he cannot have any reason to try to increase people's awareness of how the world really works other than a genuine desire to play the role of the teacher. Many have attacked the book as arrogant, but it must be remembered that anyone who goes against the common ways of thinking is essentially suggesting that he or she understands things better than do most people and therefore cannot help but come off as arrogant. Several times in the book Taleb specifically states that he falls victim to the tendencies that he condemns, and that the main difference that he sees between himself and others is that he is at least aware of it.

Considering the fact that Taleb blatantly argues that many who consider themselves the rulers of the universe were in fact a group of lucky fools, it is inevitable that many will come away from it with a sense of anger and a refusal to believe it. I am therefore almost surprised that the book has not drawn harsher reviews than it has, for Taleb was certainly not seeking to make friends through the publication of it. I suspect that those who rate the book as poor fall into two general categories: those who were troubled by the thought that a considerable portion of their success may have resulted from luck, and those who are attached to their current views on the workings of the markets and are hostile to any new views on them. These two categories naturally overlap quite often. An important thing to remember is that even if you work very hard, not only are the outcomes of your projects the result, to varying extents, of chance, but chance also played a role in getting you to the position where you can work hard and actaully see it pay off. Considering the complexity of the world we live in, and the infinite forces that push and pull on our lives, this book is critical to anyone who desires an objective veiw of how things come to be...

3.0 out of 5 stars Intiguing but ultimately unsatisfying April 30, 2002

By David Amann

Format:Hardcover|Amazon Verified Purchase

I bought FOOLED BY RANDOMNESS after reading the Malcolm Gladwell profile on Nassim Nicholas Taleb in the April issue of the New Yorker. Like others who have reviewed this book, I found that Gladwell captured the most important details of Taleb's thoughts in a shorter, more entertaining way. However, I thought that this book can be a worthwhile read for those with a passion for this type of book.

FOOLED BY RANDOMNESS is an introduction to the difficulties human beings have at reasoning around probability. Taleb argues that human beings are genetically hardwired to misattribute the results of human endeavors to skill and knowledge that are, in fact, just coincidental, random events. Taleb discusses the results of this embedded flaw in human reasoning in three areas.

In part 1, Taleb discusses impacts of `rare events' on both financial markets and on human history. Taleb argues we should beware seemingly successful strategies if they are not proven by the test of history. In particular, we should examine human history in the long term for general trends and treat skeptically claims that humanity has reached `the end of history' or `a new economic model' where the old, proven rules do not apply.

In part 2, Taleb discusses the `survivor effect', or mistaking success based on luck for success based on skill. In particular, Taleb warns against judging a strategy by its actual results. Instead, we should judge strategies based upon a sum of all possible outcomes.

In part 3, Taleb briefly discusses `tricks' he has developed to try and derail his flawed, ingrained, statistical reasoning and live a rational and, to a great degree, classical life based upon a good understanding of the effect of randomness on our lives.

The book is peppered with classical references to ancient philosophers and literature, as well as humorous anecdotes to Taleb's own experience in the world of Wall Street. Unfortunately, interesting nuggets and provocative thoughts throughout the book are rarely fully explored. While I was entertained and intrigued, when I got to an end of a chapter or section, I often felt dissatisfied, as if I was trying to wrap my arms around some meaty ideas and came away with empty air.

Unlike other reviewers, however, I did not find Taleb particularly pretentious. In fact, I often felt that Taleb was more than open with his own particular foibles and failings. His only source of pride seemed to be in realizing that he had these failings. Ironically, Taleb attributes this understanding to the experiences suffered in his own personal, contingent history.

Overall, I found the book to be like a good Chinese dinner: entertaining at the time of reading, but left hungry an hour later.
