Í dag er áhugavert að skoða hvað Taleb skrifar í bókinni "The Black Swan" frá 2007. New York Times greindi frá því nýlega að Taleb er nú mjög eftirsóttur fyrirlesari í bönkum - skyldi engan undra!
(Samantektin hér að neðan er send frá Viktori Vigfússyni):
"[Globalization] is here, but it is not all for the good: it creates interlocking fragility, while reducing volatility and giving the appearance of stability. In other words it creates devastating Black Swans. We have never lived before under the threat of a global collapse. Financial institutions have been merging into a smaller number of very large banks. Almost all banks are now interrelated. So the financial ecology is swelling into gigantic, incestuous, bureaucratic banks (often Gaussianized [bell curve] in their risk measurement)-when one falls, they all fall.*
The increased concentration among banks seems to have the effect of making financial crisis less likely, but when they happen they are more global in scale and hit us very hard. We have moved from a diversified ecology of small banks, with varied lending policies, to a more homogeneous framework of firms that all resemble one another. True, we now have fewer failures, but when they occur...I shiver at the thought. I rephrase here: we will have fewer but more severe crises. The rarer the event, the less we know about its odds. It means that we know less and less about the possibility of a crisis.
* As if we did not have enough problems, banks are now more vulnerable to the Black Swan and the ludic fallacy than ever before with "scientists" among their staff taking care of exposures... The government-sponsored institution Fannie Mae, when I look at its risks, seems to be sitting on a barrel of dynamite, vulnerable to the slightest hiccup. But not to worry: their large staff of scientists deemed these events "unlikely.""
*"I used banks as a particularly worrisome case of epistemic arrogance*/ /--and the use of "science" to measure the risk of rare events, making society dependent on very spurious measurements. To me a banking crisis --worse than what we have ever seen -- was unavoidable and NOT A BLACK SWAN, just as a drunk and incompetent pilot would eventually crash the plane"
