Nassim will present his first medical paper on antifragility on Monday, November 28 at the University of Pennsylvania School of Medicine. On Facebook, Nassim says that this is “basically, a more technical version of the book Antifragile.” He also adds “Note that this is not making any standalone empirical point, rather gluing various phenomena under the convexity argument, with necessary connections (if… then necessarily).”

Nassim Taleb has linked to a new paper on his Facebook PageHow We Tend To Overestimate Powerlaw Tail Exponents

October 2012
In the presence of a layer of metaprobabilities (from metadistribution of the parameters), the asymptotic tail exponent corresponds to the lowest possible tail exponent regardless of its probability. The problem explains “Black Swan” effects, i.e., why measurements tend to chronically underestimate tail contributions, rather than merely deliver imprecise but unbiased estimates.


A reader has sent in a copy of Nassim’s Lecture notes from when he was teaching a course at the University of Massachusetts, Amherst, MA in 2005. The course/lecture series are titled: Randomness, Decisions, and Human Nature (SOM 797R – SYLLABUS).
