“[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.

Summary: one of the "bestest" book ever
Comment: This book is definitely one of the best books ever...I claim to be a mathematician somewhat having gained straight A's in pure and applied mathematics and advanced mathematics with (a boring) engineering degree at a number of UK univerisities, and after years of dabbling in options trading and having experienced first hand; Black Monday (black swan?), the Asian Economic Crisis, living in the epicentre of SARS (lucky to avoid it), and being in this market whilst we have one of the greatest financial crisis ever since the great depression..this book in my opinion is a real diamond and i reckon Taleb is a genius. I agree with his logic and found his book so good I just could not put it down.. I would recommend this book to anyone trying to find "direction in life"(there is none cos it may be random) or those who are going thru major change in life, or simply those who are bored with life and need another " angle"...I agree totally with his analysis of noise vs market movements, and his view of how so many people misunderstand probablility and statistics...and yes I do have an MBA and did find the degree useless...this book "probably" would have been more useful in my career for sure! brilliant book!! Well done!

Summary: An insightful view of life
Comment: Some years ago, I had a colleague who organized a Mark 6 pool among friends. They had a database of previous Mark 6 results and from it derived that some numbers were more easily drawn than others. They then collectively bet on such numbers which they believed would have a higher probability of winning. I asked him the basis of his action. He explained that the fact some numbers appeared more frequently was real as proven by the statistics. The reason could be the material of the paint of different colour, the difference in the shape of the numbers painted, or their different position before drawing. Although the factors would be too complex to compute, the results shown in the statistics were sufficient to show the bias. By the time I left the department, the pool was still losing money.
It is not a coincident that the essence of the book is exactly on the same thinking. Taleb points out that human beings always overestimate causality, and we tend to view the world as more explainable than it really is. An example used in the book is the performance of stock and option investors. These investors use sophisticated statistical methods to analyze the performance of the market in the past and predict the future. The information they derived from analyzing the past may adequately explained what happened. However, the performance of the market on the following day has no relevance to the past. It is a Brownian movement which only depends on the factors at present. It is actually more random than expected.
For that matter, people always confuse between randomness and causality. The book gives an illustration on the two corresponding sides of such thoughts:
Randomness v Determinism
Probability v Certainty
Belief v Knowledge
Coincident v Law
Forecast v Prophecy
Lucky idiot v Skilled investor
Survivorship bias v Market out-performance
Stochastic variable v Deterministic variable
Noise v Signal
It is not surprising that such thinking would attract objection from the skilled investors. There are a lot of comments on this book defending the reliability and almost certainty of statistical analysis and prediction of market movements. However, from the market performance in recent months, I tend to believe that the market is much more random than we thought.
Since human being developed self-consciousness, or the soul if one likes to call it, we always wonder why things happened. This quest for reasons has also developed into the religion delusion. This innate property of the human mind makes it easy for us to attach reasons, whatever they are, to nearly everything. Thus we are easily fooled by the randomness of nature, which is now beginning to be recognized in modern science such as evolution biology and quantum physics. For the ordinary people, it is useful to reflect on the randomness misconceptions discussed in the book.
There is a survivorship bias in many statistical data we gather. We see the winners and try to learn from them, while forgetting the huge number of losers. The case study used in the book is the survey of the earning ability of the stock and option traders. While a lot of data on the traders in business can be gathered, the survey is actually gathering only the data from the survivors. Data on many traders who lost money and dropped out in the previous years are all ignored. Thus the statistics is unreliable. Let's say we want to survey among government executive officers on how the university graduates adapt to government work. We are only surveying the survivors of the government recruitment. University graduates who do not make it are all missed. If we conduct a survey in an online forum on the habit of people using computer, we are only surveying those surviving in the forum. Such statistics need to be qualified on their target participants. However, there is a misconception that survey with survivorship bias can be applied universally.
Many probabilities have skewed distributions. Many real life situations do not have a 50% probability like the two sides of a coin, but have unusual and counter-intuitive distributions. People can often be fooled by the fact that they won a bet 50 times and think that they will win next time with absolute certainty. Taleb opines that some aggressive stock and option traders eat like chickens and go to the bathroom like elephants. They earn a steady small income from selling the stocks and options, but when a disaster happens they lose a fortune. They are fooled by the randomness of the market which is hidden from them.
There is the story of black swan on probability, on which Taleb eventually wrote another book. Swans in Europe are white. People may take numerous observations to prove that swans are white. So a fact is established that all swans must be white, and the probability is 100%. However, it only takes one twist in the DNA to turn one swan black and the probability is re-written. In fact, black swans are found in Australasia. The impact of the highly improbable is severe. The more improbable it is, the harder the impact when it happens. Another joke on the false improbability is when Taleb observes an old man everyday to see if he is still alive. For eighty years, there have been about 30,000 observations and the old man is still alive. With such a large number of observations, he could conclude that this old man must be a superman who is highly improbable to die. By the track record, he may even live forever. But it only takes one death to turn the probability to zero. The truly scary thing is that the black swan could be a random event. That means it is capable of happening any time to turn a high probability totally upside down.

Summary: Methods of thinking and mental models worth learning
Comment: Every once in a while, someone really intelligent focuses his thoughts on the most valuable skill a human can have--how to think. Nassim Taleb has done an admirable job at just that: not telling us what to think--but showing us how to think in ways we can apply to innumerable life situations. I'm talking about what Charlie Munger refers to as "multiple mental models."
The most important ideas explored are those of Popper--the idea of the open society--one in which no theory is known with certainty--only with probability, and theories continually replace one another as more information comes in. Interestingly Taleb continually cites Soros as a famous investor who utilized Popper's ideas, but Warren Buffett, the ultimate realist, if queried, would no doubt acknowledge Popper in influencing his thinking. In contrast to Soros and Buffett would be Bill Miller, an intensely philosophic investor, who recently has classified himself as an optimist--but not a realist. In any case, the methods of thinking propounded by Taleb fit nicely into what Charlie Munger classifies as "mental models"--doubtlessly useful stuff for the introspective, philosophical investor.

Summary: An Insightful Rant
Comment: This book reads a lot like a self-absorbed blogger's rant, but it is a rant that is highly satisfying to read. Almost all of us have a distant relative or friend who is allegedly a "stock market genius". Taleb argues that it is usually hard to know whether that person is truly skilled or just lucky. He argues that most often trading success is either the result of ones arbitrary trading style happening to jibe with market conditions or a product of exposure to volatility in a way that allows for small regular gains leading eventually to a spectacular blowup.

Summary: An exercise in self-justification
Comment: One of the most self-congratulatory, didactic books I've ever read. Taleb is a convinced ideologue whose expertise in stock trading has created the conviction that he sees the invisible hand at work.
He constantly reminds the reader that he is writing, restating and recasting sections with a reference to his earlier statements (never trust a writer that quotes himself) while dismissing whole schools of thought by selectively quoting from philosophers to make them look silly and misguided--if you read any philosopher, they will eventually prove themselves silly and misguided. It happens when they take themselves too seriously, which Taleb certainly does.
Overall, his ode to skepticism is well conceived, but very thin. Unfortunately, it seems to be the only idea he ever tested. He makes the frequent mistake of confusing the success of a rigorous analysis for the justification of a philosophy as a guiding system to thought for others.
Ultimately, philosophy is what Taleb suggests science is, taking the ideas of Karl Popper over the top and placing them on an alter, "science is mere speculation, mere formulation of conjecture." Popper was a solid skeptic, while Taleb is a convinced acolyte.
