Pompous and annoying July 17, 2008 7 out of 10 found this review helpful
As others have observed, there are a couple of good ideas in this book. The style, however, makes it practically unreadable. I actually listened to the audiobook; one of the editorial reviews comments that the reader salvaged the work somewhat by softening the sarcastic and annoying tone; I did not find that to be the case. It's hard to blame the narrator, as he seems to have captured more-or-less the author's intent.
The "couple of good ideas" are fairly straightforward. One, don't assume that you know the form of the probability distribution of any given social or economic phenomenon. That's good advice. It's often easy to find a function and a set of parameters that appear to fit a given historical data set; but just because the function appears to fit historically doesn't mean it's going to be predictive. Two, if the form of the distribution is unknown and unknowable, then computed measures of "risk" are not reliable, as risk is in fact incalculable. So, a good investing strategy is to avoid assets whose valuation depends on risk estimates, and seek out certain other assets. Following that strategy would have kept you out of a lot of the asset classes that have melted down recently.
The most frustrating problem with the way the book is written is its lack of self-consistency. For example, there is a long discussion of "silent evidence": just because you don't observe something doesn't mean it's not there. Then, over and over again, Taleb tries to assert that no one in business, or the social sciences, or this or that domain understands a certain issue correctly. Even if we assume for a moment that Taleb's understanding of the point in question is correct, and that he is therefore qualified to pass judgement on who is a Right-Thinking Individual, the fact that he has not encountered any Right-Thinking Individuals does not mean they don't exist. He may not have met them; or he may have met them and not been listening when they spoke; or he may have met them and presented his ideas in such a contemptuous way they chose not to engage in conversation, concluding there would be no value to themselves in it.
Then there is the rant against the bell curve that occupies the last chapters of the book. Kind of silly to get angry at a mathematical function. It's like criticizing a hammer for not being a screwdriver. In a few places the author does draw the distinction between appropriate uses of the bell curve and inappropriate uses, which is of course the (perfectly reasonable) point he is trying to make. Most of this section, however, is written in a much more sloppy and imprecise way, so that any sentence or paragraph by itself comes across as criticizing the hammer. To make sense of it one has to keep saying to oneself "well what he really means is that there are certain people who misuse this tool, and they shouldn't."
Similarly, the assault on academic economics and the Nobel Prize. Not many people would argue that idealized models are predictive of reality. That's not the same as saying they are without value; it just means one has to know what to use them for. The author does find value in behavioral economics, but somehow when attacking academia seems to forget that a) behavioral economics is all the rage today in academic circles, and b) the Nobel committee, who Taleb considers so clueless, awarded Kahneman the economics prize for inventing it. [Another self-consistency issue here: after a very lengthy discursion on the value of empiricism and the fallacy of oversimplified models, Taleb confidently repeats numerous experimental-psychology and behavioral-economics results as "the way we behave," where by "we" he means all of humanity, excluding perhaps himself the Enlightened One. In fact, most of these results are based on very small samples, so while they are indeed interesting, the authors generally go to great lengths to explain that what they have observed COULD have a certain meaning or cause, but that the data are not conclusive, as other causes could have led to the same observations.]
Great books are like great friends. Even when they challenge your ideas, you want to enage with them because it's such a pleasure. This is not such a book. The ideas, while interesting, are not as controversial as the author claims, and they aren't worth the pain of struggling through the writing.
Great idea - mediocre presentation July 8, 2008 3 out of 6 found this review helpful
I listened to the audiobook. I think the idea behind this book is very, very interesting - life is shaped more by random (non-predictable) events than by anything one of us can foresee. That being said, the author has filled the book with several anecdotes that are somewhat meaningless (eg, the fictitious Russian author) and/or irrelevant (autobiographical details of his life) - hence the 4 stars, rather than the 5 stars the idea deserves. It appears that at times, he is trying to be too clever by half, and destroys the rhythm of ideas by being too verbose. Some of his sentences are very convoluted, and I found myself having to rewind and listen to some sentences more than once to figure out what he means by what he says. I found the parallels with Asimov's futuristic science fiction Foundation series- where Harry Seldon constructs his of mathematically predicting the future, but is thrown off by the unpredictable appearance of the Mule (=a black swan). It is odd, especially in the context of this book, that over so many millennia that the Foundation existed, why only one such even that was so enormously disruptive occurred. According to Taleb, they should be occurring much more commonly. Had this book been written better, I would have given it 5 stars.
The Black Swan is a Red Herring July 5, 2008 3 out of 6 found this review helpful
Nicholas Taleb has seemingly spent his entire life chasing what he refers to as the black swan. A series of highly improbable events that have continuously shaped the course of human history. He presents his description of this phenomenon in what might be termed an autobiographical manifesto of sorts, the exhaustive and seemingly endlessly referenced book, "The Black Swan -- The Impact of the Highly Improbable". It's not that Taleb isn't onto something, or hasn't written a thought provoking book, he has. But Taleb has not given us a black swan. He has given us a Red Herring. He has taken a small piece of stinky fish and dragged it in the dirt perpendicular to the path we are on. There is a small benefit, if we leave our path momentarily to gain a new perspective, new insights will emerge, but that is all our feeble brains can comprehend, and nothing more. But to believe there are no thinker's among us who do not understand the need to search for the extraordinary and to try to link them to potential causes, that although we might not understand completely, are contributory and can indeed be rectified, is not to be an observer of the human race at all. Ultimately he is wrong about the Black Swan but he is right about the requirement for us to think outside the box. But this has been said before. Taleb just reminds us.
First 2 chapters are worth the price June 26, 2008 3 out of 3 found this review helpful
The research based information on the psychology of marketing, buying and selling that are described in the first two chapters are little known, facinating and extremely useful for those at many levels. Detailed discussions of "decoys" in marketing products, the relative comparisons involved in almost all buying decisions and the incredible effects of "free" merchandise such as Amazon's free shipping are given in an interesting and engaging way. After that the impact and interest of the information declines with each chapter and by chapter 7 it is hard to tell what the focus of the book (audio) is. A guess would be that after chapter three it just goes on to whatever the author found interesting and researched.
A great book long over due June 19, 2008 2 out of 4 found this review helpful
The author, I think, is one of the great thinkers of our time. I enjoyed his work. On YouTube, there is a long interview of Mr. Taleb by an old guy. It was a disaster in that the interviewer has almost no knowledge about what what Taleb was talking about (including chaos, ...) and consistently interrupts and makes annoying noises. Therefore, I could only partially tell what Taleb was trying to say and I knew it was something important. Being unable to completely hear and see what Taleb attempted to say, I bought his book. Anyhow, it is not a technical book, it's fun with lots of history knowledge and intriging to read. I recommended it to many friends already.
