Great Book

What a great book! For all of us hard decision makers out there, this book really helps the psyche and will to "just do it." If you are looking for a book that will help you lose control and gain mental health, this is a good one. http://www.netvibes.com/lenny3

We are experiencing a dramatic shift in America where individuals are assuming greater risks. The old defined retirement benefits plans are being replaced by defined contribution plans (i.e. 401k plans). Under these contribution plans, it is the employee who makes the investments decisions and faces a loss in retirement wealth when these investments sour. Job security is not what it once was. Our future well being is becoming increasingly dependent on random events. This makes the topic in Taleb¿s ¿Fooled by Randomness¿ very timely. In order to make good decisions, we need to be both financially and statistically literate. Taleb¿s book gets us off to a good start. All too often we mistake random events with deterministic ones particularly when judging a person¿s past performance. If this book is worth buying it is because of the Table P.1 that summarizes how we can make faulty judgments by ¿being fooled by randomness.¿ After this, it deteriorates. He does not explain important concepts correctly, and he tries to give the impression that nobody accounts for randomness. He criticizes mathematicians for ignoring randomness, even though there is an entire field in mathematics devoted to understanding randomness. Taleb is confused. Risk adverse individuals attempt to avoid the potential ill effects of randomness however, this does not mean that they avoid the understanding of randomness. Randomness can be synonymous with vulnerability. The book is filled with contradictions where he says one thing and a few pages later reverses himself. For a PhD he has an amazingly poor grasp of probability theory. No wonder he does not like mathematicians, he does not understand the discipline. Although he claims that financial markets are unpredictable, he claims to have a trading strategy that guarantees him positive profits. Go figure. No where in his book does he discuss the concept of conditional expectation. His fictional characters are not convincing. The ¿risk averse¿ Nero is supposedly buying Treasuries when he could get a higher and equally safe after tax return with buying municipal bonds. The worst part of this book is the moral implications. All of life is uncontrolled randomness. Our decisions and our efforts do not matter and there is no role for personal responsibility. People who do try to explain randomness or who try to take responsibility are personally attacked. After writing this book, Taleb appeared on CNBC TV. He told the announcer that if a person comes into your office and uses the word ¿standard deviation¿, you should throw him out. The announcer asked Taleb why this should be done. And Taleb responded, ¿Because everything is not normally distributed.¿ Do I need to say anything more?

    Good Read

    Simply put, this book breaks down many of our preconceived notions of probability.
