nassimWhen a friend's daughter is unattractive, one often says something like, "she has such pretty eyes", or "she has such pretty hair". Nothing screams louder than a sympathetic evaluator who can only manage a lame compliment.

So I laughed when Tyler Cowen tried to praise Nassim Taleb's Black Swan over on Slate:
In The Black Swan, he preaches a bracing sermon in favor of an angst-ridden, but socially beneficial, plunge into wrestling with the unknown.
Such as...when you see a tiger and you run away (!), or embrace a new paradigm. Then Cowen brings up some practical examples:
Oddly [sic], Taleb's argument is weakest in the area he knows best, namely finance. Only on Wall Street do people seem to give proper credence—not too much, not too little—to very unlikely events. It is easy enough to use hindsight to identify the black swans Wall Street has missed, such as stock-price crashes. But it is harder to argue that the market undervalues surprise more generally...Yet "long-shot" strategies are well-studied, and they do not yield extra profit.
[That was my main critique when TBS came out.] You see, it's a great book, except when the author talks about his area of greatest experience, or anything specific (power laws? Old news says Cowen). It's great talking about 'the next Harry Potter', and paradigms, embracing randomness (how?). But Taleb does skewer those Platonist fools who 'confuse the map for the territory' as the hippies used to say [if only I had a nickel for every article that expanded on the fuzziness of categories, noting that every conceivable concept--black race vs white race, nature vs nurture, introvert vs extrovert--involve overlap and exceptions.]. As a self-described empiricist, you would think this might bother Taleb, but to his acolytes his vagueness and inconsistency is a sign of Hegelian profundity as opposed to mere confusion.

Technicolor Swans
You see, it's a great book, except when the author talks about his area of greatest experience, or anything specific. Humor is the best remedy, but see, Nissim Taleb manages a fund according to his Black Swan doctrine, and it seems to be making money.

His flagship fund, Empirica Kurtosis, died a couple years ago. Like all dead funds, this had absolutely *nothing* to do with performance according to the proprietor. He's now 'on the board' of some little fund, but that doesn't imply much portfolio management, more like fodder for marketing (lots of book buyers, I'm sure it helps).

Last time you wrote something about his fund, Taleb suggested me to get a lawyer or a compliance officer. I thought my reply was cool... until recently, when I read the following in Paul Strathern's book "A Brief History of Economic Genius":
"[I]n 1660 [Sir William Petty (one of the first econometricians)] was challenged by an irate Irish landowner, Sir Aleyn Brodrick, to a duel. Petty's response gives some measure of the man. Despite his physical disability, to ignore the challenge would have exposed him to censure as a coward and public mockery. So he exercised his right, as the receiver of the challenge, to name both the weapons and the location of the duel. He chose "a dark cellar, and the weapon to be a great carpenter's axe." This turned the whole thing into a farce, and Brodrick withdrew in disgust."

Thanks. I stand corrected. A Google search would have revealed that The following Resolutions of Empirica Kurtosis Limited, were adopted by the sole Member by written consent on December 2, 2004: that the Company be wound up voluntarily pursuant to the provisions of The Companies Act...

Tyler is contrarian, if he respects you and you hate Taleb's book, it makes him want to praise it somehow. I'm sick of attention being heaped on Taleb, everything he's posted makes him seem like a jerk; the meanest and best thing we could do is ignore him, but no one can resist one way or the other.
