The result of that blog entry, and of a few other criticisms of Taleb in various places, is that Nassim has now published an extremely useful technical appendix to The Black Swan. It includes substantially all his relevant scientific and technical papers, and essentially comprises a gauntlet being thrown down to those who would criticize him. If you want to attack my ideas, he’s saying, that’s fine, but please first do me the favor of looking at where they’re laid out in detail, as opposed to where they’re laid out in newspaper quotes or in a literary book.
Some people make technical comments on a literary book (TBS was presented as aliterary-philosophical essay), but do not go after my technical works thatpresent analytical discussions and empirical evidence. I find it flattering (ifunchallenging) to only be attacked in the wrong places, but it is more honestand more helpful for scientific progress (and more dignified) if the technical authorscommented on technical works AND DID NOT DISSEMINATE A WRONG PRESENTATION ABOUTMY IDEAS (Fama, Scholes,Engle, etc.) Actually, no: this is VERYdishonest. I will consider it bad faith toattack the statistical statements in my literary work without looking at thetechnical documents and will not spare any shady academic who does so.
Where I explain the problems, show how to deal with it(“what to do about the Black Swan”) and provide exhaustive DATA:

Somebad-faith commentators (say like Richard Bookstaberor Eugene Fama) are distorting my idea: TBS is not “against the Gaussian”,but largely the apriorism in the measurement of tailevents and the consequences of errors (see the epistemology papers). The papers below show how the problemis not “Gaussian-NonGaussian” but related theconvergence to the Central Limit Theorem in real time. Domain 1 converges toCLT (fat tails or not), Domain 2 does not (finite variance or not). Fama is still trapped in the 1960s paradigm Gaussian v/sPareto-Levy-Mandelbrot basin; I believe that 1) we do not converge the PLM inreal time (preasymptotics), and 2) we suffer fromsevere inverse problems as we do not observe distributions.
I summarize: the three problems are:
· Pre-asymptotics (all that happens takes place outside the limit),
· InverseProblems(many models can explain the same phenomena), and
· Platonicities (the reduction of the fool)
all thesame illness under different symptoms.
