[YouTube] A Discussion With Scott Patterson’s About His Book Chaos Kings, Part 3
- Why Ilmanen-style “simulations” of tail performance are both theoretically and empirically flawed because of:
- The need to extrapolate extremes.
- The Niederhoffer problem.
- The birth of the Non-Naive Precautionary Principle in East Anglia, in a pub discussion with Rupert Read.

+ Meeting Mandelbrot & discovering a wealth of processes generating grey swans
+ Meeting Kahneman
+ The 3-day meeting with the Harvard geneticist George Church, involving Elon Musk, Anne Wojcicki, Larry Page, Richard Thaler, & others that triggered the non-naive version of the precautionary principle.

[YouTube] MINI LECTURE 18 (MORE TECHNICAL): How to build a positive definite correlation matrix for Monte Carlo Simulations for a set dimensionality
How to build by tinkering with a positive definite correlation matrix for Monte Carlo simulations for a given dimensionality.
[YouTube] MINI LECTURE 17: Maximum Ignorance Probability (a bit more technical)
What do you do when you must estimate a probability and there is ZERO information? A surgeon did 60 operations with 0 failure. What’s her or his failure rate? I didn’t realize that the trick wasn’t in the literature until John Hughes wrote a paper in Statistics and Probability Letters based on my blog post presenting the idea.
[YouTube] MINI LECTURE 16: On the Absurdity of Standard Genetics Reports
Why reports from genetic firms saying you are 30% Greek, 15% Sicilian, and 5% Martian are complete misrepresentations?
[YouTube] MINI LECTURE 15 – Conditional vs. unconditional correlation: twin studies overestimate heredity
The genetics of twin studies have a bias showing more heredity than in reality, owing to a statistical artifact. The twin studies for heredity are based on comparing the correlation between 2 identical twins minus that between 2 fraternal ones (assumed to be sharing half their genes). The use of fraternal twins as control is assumed to extract the “environmental” factors. Problem: Correlation is conditional and psychologists think it is unconditional. We show how the math is entirely different. The core error is that genes and environment are not separable and additive.
[YouTube] First Course on Fragility, Convexity, and Antifragility (Nontechnical)
A first, very introductory presentation of fragility as linked to both nonlinearity and dislike of variations. Antifragility is almost the opposite, limited to a specific range of variations.
Explains:
- Why everything fragile must be concave.
- The medical S curve.
- Why harm to the climate is necessarily nonlinear in dose response.
- How hospitals can be overcrowded unless there are redundancies.
Further discussions will be more technical.
