This book is about luck -- or more precisely how we perceive and deal with luck in business and life. Set against the backdrop of the most conspicuous forum in which luck is mistaken for skill -- the world of trading -- Fooled by Randomness is a captivating insight into one of the least understood factors in all our lives. Writing in an entertaining and narrative style, the author succeeds in tackling and explaining three major intellectual issues: the problem of induction, the survivorship biases, and our genetic unfitness to the modern world.
The book is populated with an array of characters, some of whom have grasped, in their own way, the significance of chance: Yogi Berra, the baseball legend; Karl Popper, the philosopher of knowledge; Solon, the Ancient World's wisest man; the modern financier George Soros; and the Greek voyager Ulysses. In addition we meet the fictional Nero, who seems to understand the role of randomness in his trading life, but who also falls victim to his own superstitious foolishness.
But the most recognizable character of all remains unnamed -- the lucky fool in the right place at the right time. The embodiment of the "Survival of the Least Fit." Such individuals attract devoted followers who believe in their guru's insights and methods. But no one can replicate what is obtained through chance. A monkey banging on a keyboard may eventually produce the Iliad, but would you sign him to write the sequel? Are we capable of distinguishing the fortunate charlatan from the genuine visionary? Must we always try to uncover non-existent messages in random events? It may be impossible to guard ourselves against the vagaries of the Goddess Fortuna, but after reading Fooled by Randomness we can be a little better prepared.

This book is a complete waste to read. The analysis and arguments are extremely dull and elementary and are written in a very pedantic style. It is more one man's personal insults to all those who have far exceeded him in trading the markets. There is nothing of value in this book.
Taleb doesn't put as much math in the book as I'd like, or expected, but the point he gets across is awesome. Seemingly anecdotal, at times, he incorporates lots of stories which range from Roman rulers to traders on the exchange floor. Absolutely excellent.
The narrator may come across as having a big ego, but he is absolutely charming. He lulls you into his world with a totally different logic. He sees randomness where you suspect none and convinces you.
Every person who is interested in investing should read this book! In investing, few can tell the difference between being lucky and smart. Being successful in the short term can come from either source. If it is coming from unrecognized sources of luck, however, the behavior that the investor associates with success can sink the ship. The cautionary tale of Long-Term Capital Management is cited in the book as an example of this point. ¿If you¿re so rich, why aren¿t you smart?¿ is the wonderful reversal here on the old saw. I see this effect all the time in my consulting practice with helping companies understand how their decisions affect their stock price. A large percentage of people feel that they know all the answers when their stock price is rising. They keep doing the same things when the stocks are falling. Few survive to still have top jobs when the cycle shifts again. Then a new group of self-confident people take over who often don¿t know any more than those who preceded them. It¿s just that their track records look better. Fooled by Randomness will help make you more knowledgeably humble about what you can expect to accomplish with investments. Not only do fewer than one percent outperform the market averages over long time periods, the ones who do are probably often being aided by luck as well. ¿Get thee to the index funds as soon as possible¿ is the message that most should take away from this book. Better yet, buy them when multiples are low! The book¿s fundamental point is that there is tremendous volatility in any investment. Ignore that volatility to your peril. At the same time, you should be cautious about how well you understand the volatility. Stocks at their lows can still go to zero. There are all kinds of events that can happen, that have not done so yet. When they do, throw out all the old rules of investing. The terrorist attacks on the United States last week are probably an example of this. So each investment must be made as though you could be totally wrong. This means that you have to manage your risk exposure to events you don¿t even know how to expect. I loved his example of the joint probabilities of having a rare disease if you get a positive result on a test for that disease. Even most doctors apparently don¿t know how to evaluate that one. If even well educated people cannot quantify two known risks occurring simultaneously in their own field, how can investors be expected to make good decisions? Dr. Taleb has some very good advice for how to handle the psychology of being able to do this. He upholds the Stoic ideal -- ¿the attempt by man to get even with probability¿ which encourages ¿wisdom, upright dealing, and courage.¿ This means not chasing the latest investment fad or fashion, not looking at your investments very often, and being open to both sides of any idea (it could go wrong as well as right --what are the consequences of both?). I especially liked his idea of watching CNBC with the sound off so that the ¿experts¿ seem humorous and you are less likely to hear and follow their advice. Even more poignant was his advice not to live on Park Avenue where living with all of the arrogant, temporarily lucky can make you feel small. Instead, live somewhere that the results of your cautious approach will cause you to be the envy of all. Dr. Taleb impressed me with his willingness to tell stories on himself about how quickly he can become superstitious when things are going well, take on excess risks, and start looking too short term. After all, we are only human! The importance of this book can only be appreciated if you go back and think about your biggest investing successes. How much was luck versus skill? A good way to test is to see if the same approach has continued to work for you whenever you use it. Another good test is to see how often it would have backfired in the past.
