@nntaleb Hint: as volatility rises, because the distribution is bounded to the left, the probability of exceeding any level goes to 0, with the mass a Dirac at 0. The point is that all the expectation is owed to a single low probability tail event. pic.twitter.com/0y0M1bhFDK Permalink 12:00 PM – 12 Mar 2019

@nntaleb Using an unreliable measure s.a. IQ on grounds that that’s “what best we got” and “science” proceeds that way” (it doesn’t) is accepting self labelled “bullshit” as scientific statements. And this Bullshit is a technical term in philosophy: the disrespect for Truth. Permalink 5:54 AM – 10 Mar 2019
@nntaleb Not my point. My point is that IQ doesn’t even measure that part of intelligence it is supposed to measure. Permalink 4:02 AM – 10 Mar 2019

This tutorial presents the intuitions of the randomness of sample correlation (spurious correlation) and the methodologies in derivations.
Some later sections are somewhat technical as rederived an old equation with more precise functions (in order to apply to fat tails) and showed the distribution of the maximum of d variables with n points per variable.
This paves the way to the real scientific work on random matric theory under fat tails and failure of Marchenko-Pastur.
