@nntaleb SOLUTION: market expects +/- 11.3% swing. This is a classic confusion because operators don’t understand what “volatility” means. Just as psychologists who deal with “correlation” and p-values don’t know what these metrics mean. pic.twitter.com/pLqoArwyh6 Permalink 4:55 AM – 12 Mar 2020

@nntaleb 2) Point is: all we need to do is slow down the growth, CUT THE TAIL–we can’t eliminate it. Unfair to favor the UK but simpler to execute.

@nntaleb Kluuuuuuelessly dangerous. The fellow @vaughanbell is a psychologist. Invokes “evidence based”: you need “evidence” of a crash before putting your seat belt on.
