Oct.16 — The Black Monday crash was 30 years ago this week. “Black Swan” author Nassim Taleb was a trader for First Boston at the time. He made a lot of money while others lost fortunes. He recounts the experience with Bloomberg’s Erik Schatzker.
The difference between 100 people going to a casino and one person going to a casino 100 times, i.e. between (path dependent) and conventionally understood probability. The mistake has persisted in economics and psychology since age immemorial.
A central chapter that crystallizes all my work. In forth. Skin in the Game Time to explain ergodicity, ruin and (again) rationality. Recall from the previous chapter that to do science (and other nice things) requires survival but not the other way around?
[One of the more technical (and optional) chapters, at the end of Skin of the Game]
Rory Sutherland claims that the real function for swimming pools is allowing the middle class to sit around in bathing suits without looking ridiculous. Same with New York restaurants: you think their mission is to feed people, but that’s not what they do. They are in the business of selling you overpriced liquor or Great Tuscan wines by the glass, yet get you into the door by serving you your low-carb (or low-something) dishes at breakeven cost. (This business model, of course, fails to
The diversity discourse appears to serve an insidious form of racism and Northern Euro supremacist agenda (with a redefinition of the Western world and a reframing of the classics). Please stop classifying people according to race, and stop creating racial stereotypes and divisions in the name of “diversity”, while doing some smug virtue signaling. Look up “framing” in a decision theory textbook and you can see what I mean. This is no different from funding Al Qaeda headcutters and women-enslavers in Syria in the name of “democracy”.
Aug.16 — Nassim Nicholas Taleb, adviser at Universa Investments, sat down for an interview with Erik Schatzker Tuesday evening in New York. Taleb, famous for his assessment of risk, says there are greater risks out there than nuclear war with North Korea.
Nassim Nicholas Taleb talks with EconTalk host Russ Roberts about the manuscript version of his forthcoming book, Skin in the Game. Topics discussed include the role of skin in the game in labor markets, the power of minorities, the Lindy effect, Taleb’s blind spots and regrets, and the politics of globalization.
What was meant to be a “typical” of Roman Britain by the BBC: flowing quotas of political correctness backward in time.
The BBC did some kind of educational cartoon on Roman Britain and represented “diversity” in terms of someone looking African in the show as representative of “diversity” at the time. The BBC was effectively applying quotas retroactively (I mean, really retroactively). Any dissent from the statistical errors made by the politically correct police is treated as apostasy. Effectively, scholarship is dead
For fat tailed distributions, the empirical distributions does not reflect the true statistical properties, particularly for extremes. This is a simplified side note to a paper with Mark Spitznagel on why people make a mistake by looking at raw historical data as “empiricism”.
So I am fed up with academics who say “we know it is fat tails” yet not understand the consequences.
I will always remember my encounter with the writer and cultural icon Susan Sontag, largely because it was on the same day that I met the great Benoit Mandelbrot. It took place in 2001, two months after the terrorist event, in a radio station in New York. Sontag who was being interviewed, was pricked by the idea of a fellow who “studies randomness” and came to engage me. When she discovered that I was a trader, she blurted out that she was “against the market system” and turned her back to me as I was in mid-sentence, just to humiliate
