Taleb studied the markets and came up with his theory of randomness that uses mathematical models that relate to the real world to debunk the all-powerful hold on the public imagination exercised by the bell-shaped curve. The main point is that Gauss hides the rare events (black swans) at the extremes of a distribution and therefore underestimates the potential for destabilisation (of any system but particularly our social systems) that the occurrence of one of these events can actually exert on our lives. Good, strong and well-argued case; it attacks mainstream economic theorists for delivering ideas beased on detailed algorithms that give spuriously accurate results. The impact of the black swan events is unrecognised and therefore any theories so based will fail to work properly when they are most needed. Added to which, he finds time to suggest that we live our lives incorrectly when we think that it is necessary to run for a train. 'Don't run for trains' is his motto (derived from Mandelbrot) - it is beneath your dignity and life should not be lived at that level but in a more elevated and aesthetically defensible manner. Great inspirational read - to read again.

Fascinating stuff, but crippled by faulty premises. Whereas I can understand a person without a faith positing that there isn't a higher rationale guiding the universe, but I have a harder time with his assertion that his unique life with little responsibility gives him a clearer view of humanity. Essentially, he’s a classical erudite Epicurean who vilifies Platonists--who ironically boosts his huge ego through supposedly attempting to be pragmatic to the common man. Never mind that his scorn for common life cripples his ability to actually see things as the typical man (who he attempts to champion) does. ( )

The author is a Lebanese expatriate who never got to go home permanently after the never-ending war in Lebanon. He graduated college in the USA, took a job as a floor trader at an investment firm, moved on to college professorships, and consultant positions. He is a theoretical Mathematician who takes a dim view of the "experts" who predict the economic markets. History is made not by the great men or the rise and fall of cultures but by outliers, Black Swans as he dubs them, which come unexpectedly, catching us unprepared, and with devastating consequences. His advice to the would-be investor in this time of risk: "I'm not telling you not to J-walk across the street, but I am asking you not to do so blindfolded". Black Swans may be inevitable, but they can make money for those who are prepared. ( )

The Impact of the Highly Improbable is not really what the book is about.

This book reads as more of an ego-stroke, as Taleb does his best to point out that he seems to have tapped into a great realisation that nobody else seems to have grasped. He is also extremely deprecating of anyone not sharing his views.

That aside, the book is interesting, and does point out that a large number of tools in use by market financiers and speculators are limited and misleading to those who have limited understanding. Taleb stands on the authority of having been successful himself - but while he points out that his peers' success is mostly due to luck, his success follows from his 'insight' into The Black Swan.

In his own terms, there is likely a 'graveyard' of investors out there who understood the implications of The Black Swan, but were unlucky enough to bet on the wrong swan.

The book is interesting, does offer some interesting thoughts, but doesn't go anywhere near far enough in what really matters (that is, it is more important to have a plan to mitigate the effects of a Black Swan, rather than limit the odds). ( )

Before the discovery of Australia, people in the Old World were convinced that all swans were white, an unassailable belief as it seemed completely confirmed by empirical evidence.

A black swan is a highly improbable event with three principal characteristics: It is unpredictable; it carries a massive impact; and, after the fact, we concoct an explanation that makes it appear less random, and more predictable, than it was. The astonishing success of Google was a black swan; so was 9/11. For Nassim Nicholas Taleb, black swans underlie almost everything about our world, from the rise of religions to events in our own personal lives.

Why do we not acknowledge the phenomenon of black swans until after they occur? Part of the answer, according to Taleb, is that humans are hardwired to learn specifics when they should be focused on generalities. We concentrate on things we already know and time and time again fail to take into consideration what we don’t know. We are, therefore, unable to truly estimate opportunities, too vulnerable to the impulse to simplify, narrate, and categorize, and not open enough to rewarding those who can imagine the “impossible.”

For years, Taleb has studied how we fool ourselves into thinking we know more than we actually do. We restrict our thinking to the irrelevant and inconsequential, while large events continue to surprise us and shape our world. Now, in this revelatory book, Taleb explains everything we know about what we don’t know. He offers surprisingly simple tricks for dealing with black swans and benefiting from them.

Elegant, startling, and universal in its applications The Black Swan will change the way you look at the world. Taleb is a vastly entertaining writer, with wit, irreverence, and unusual stories to tell. He has a polymathic command of subjects ranging from cognitive science to business to probability theory. The Black Swan is a landmark book–itself a black swan.
