Dynamic vs Static Ruin Problems

Just found out (Facebook) I was not alone in finding something weird in economists not understanding dynamic vs static ruin problems.
It is a strange feeling to realize the answer to the question “Is it me or are they blind to something obvious?” is “no, it is not me”.
Murray Gell-Mann and colleague found the SAME point (though expressed in a more physical setting).

It is a myth that markets are there for the discovery of “the” price.(Facebook)  Markets are there so we can keep changing opinion about the price.
——
In addition, for those who believe in the “wisdom of crowds”, looks like the idea is debunked by the minority rule.

http://fooledbyrandomness.com/minority.pdf

Every century brings the fool (Facebook) who declares that “violence is steadily declining” and that we live in “unparalleled” period of peace (40 years without conflict). And, needless to say, attributes it to some type of progress. This was from H.T. Buckle circa 1857. I was shocked to find Pinker’s words… verbatim. It was not just Pinker’s reasoning, but his words.

The great F. Dostoyevsky debunked it in “Notes from an underground” (enclosed).

A common theme of “positivist-rationalists-scientistic” (that is, promoters of scientism) to believe in “end of”, new man, new society, new something, etc. Just as the “new atheists” believe that if we remove religion and replaced with something they mislabel as “science”, things wouldn’t blow up the planet. Now, looking for some quotes from Auguste Comte who, thanks to his magisterial multi-volume project, “Cours de Philosophy Positive” gave respectability to this turkey problem.
—–
Notes:
1) Dostoyevsky, as an author, had skin in the game. He faced his own execution: he was condemned to death penalty, faced the execution squad, and was reprieved last minute. See in The Idiot the discussion of how a man faces what he think is his last hours of life, promising himself to enjoy every minute of like in the same manner if case he miraculously survives… and forgetting it upon the miraculous survival. Much more on him, later.

2) The Nobel Foundation gave me a fellowhip to go study the statistical properties of violence in Oslo. So I will get deeper into this turkey problem and its sucker narrative.

3) Thanking Daniel Obloja.

When people get rich (Facebook), they lose control of their preferences, substituting constructed preferences to their own, triggering their own misery. And these are the preferences of those who want to sell them something (a skin-in-the-game problem as their choices are dictated by others who have something to gain, and no side effects, from the sale).

I’ve mentioned here the following anecdote. I once had dinner in a Michelin-starred restaurant with a fellow who insisted on eating there instead of my selection of a casual Greek place. People in the restaurant were of the very constipated style, that kind of atmosphere. Dinner consisted in a succession of complicated small things. It felt like work. I left the place starving. Now if I had a choice I would have had some time-tested recipe (say a pizza with fresh ingredients, or a juicy hamburger) in a lively place –for a tenth of the price. But because the fellow could afford the expensive restaurant, we ended up the victims of some complicated experiments by a chef judged by some Michelin bureaucrat (one that would fail the Lindy effect, instead of eating some minute local variation around a progress through Sicilian grandmothers).

(Footnote: Hamburgers are tastier than filet mignon, because of the higher fat content, but people have been convinced that the latter is better because it is more expensive to produce).

The same with real estate. Most people, I am convinced, are happier in close quarters, in a real barrio-style neighborhood, where they can feel human warmth, but when they have big bucks they end up pressured to move into a humongous impersonal and silent mansions, far away from the neighbors. Not counting the fact that their house will be professionally managed like a corporation.

I am saying this because, with the passage of time, I am more and more convinced that very few people understand their own choices, and end up being manipulated by those who want to sell them something. Looking at Saudi Arabia which should progressively revert to the pre-oil level of poverty, I wonder if taking away some things from them will make them better off.

A part man-part animal (Facebook) is vastly more horrifying than a full wild animal. Extremely eerie are monsters who look like humans with small differences.

The uncanny resides in the resemblance, not the difference.

So I finally figured out why I am gripped with so much revulsion at BS vendors dressed in the garb of high priest of scientists, intellectuals, or logicians, (say Pinker or Shermer or Harris or some scientist under Monsanto’s control), to the point of total maddening anger, and why I do not experience any disgust when I see a fortune teller, a market commentator, or some new age meditation guru such as Deepak Chopra.

FRIDAY QUIZ.(Facebook)
“People of high intelligence are ethical. We find fewer intelligent people among criminals.”
Spot the nonsense in the sentence.

When I was a quant-trader (Facebook), my trading colleagues talked about books, ideas, and quants talked about probability and mathematics. Now that I am in the “ideas” profession, my academic colleagues discuss office space, and my writing colleagues talk about book agents, speakers bureaus and copyrights. Professional mathematicians talk about grants and amateur ones about Godel.

“How do your books differ from those of [X]?”.
Me: “I don’t know I don’t often read contemporary authors, and odds are I will never read “X”.
She: “But you are writing books for an audience, no? You are responsible to tell the audience how you compare to others.”
Me: “Do you have a boyfriend?”
She: “Yes, he is here.”
Me: “Did you ask him how he compares in bed to other men at the party or is it something you found out by yourself?”

Nassim Nicholas Taleb on the Real Financial Risks of 2016

 

Last email from 2015. (Facebook)  Our paper debunking Pinker’s thesis was accepted by a stat journal Physica A: Statistical Mechanics and Applications.

Science Wins! In the months that it took us to publish this our paper was under the scrutiny of professional probabilists and statisticians who deal with Extreme Events, whose comments we collected and incorporated while Pinker and his goons were active in the press, on blogs and social media spreading stawman-clueless commentary.

Happy Science. Happy 2016!

PS- More generally I have to describe the “Pinker fallacy” under fat tails. His claim is sort of, to put it in statistical or scientific terms: “Violence has dropped by .00001 standard deviations. Let us explain WHY.”
PPS- Confirms my idea that, in science, a single comment by a mathematician can outweigh those by a billion BS vendors.

Our paper is here:

Friends, I promised to deliver in the next few hours a discussion of the most neglected fragilities and the most overestimated risks. We can tell fragility when we see it… but we first need to look at it.

Friends, we made a page for the precautionary principle (Facbook) with application to GMOs, with a variety of articles.

1) It looks like PR promoters/smear campaigners are so dumb that they don’t know that we know that they are dumb.

2) Calling GMOs “transgenics” (moving genes from one organism to a different one) better reflects their nature as genetic modification is too vague a designation.

What I think is my central piece from *Skin in the Game* (Facebook) explaining risk-loving and precaution can live together, how risk taking has a distinct logic (similar to quantum logic)… Risk management is boring, risk taking is exciting; how the two can be reconciled. How can we reconcile Aristotelian precaution and courage, both considered virtues?

Friends, this is technical. (Facebook) Here is the “Statistical Estimators Under Fat Tails Project” and my small contribution to it during 2015 (7 papers). One can see that very little has been done to understand random events under Extremistan and there is a lot, a lot to do.

Social networks are a great place for convex optionality. (Facebook) In 2015, I met three collaborators, two co-authors (one probabilist, one economist who specializes in inequality) and one business partner on Twitter (a partner with the Real World Risk Institute). I do not think that I would have been able to initially run into these three collaborators in the physical world, no matter how many parties I had attended (I attended a lot, a lot of parties in 2015). You can tell from people’s twitter conversation whether there can be a possible technical collaboration.

Ironically these technical matches revealed themselves through arguments during fights in my antiBS crusades (such as the Pinker-BS problem). Social life (physical, that is) is too harmonious, too devoid of fights and arguments for some skills to be made apparent.

Let me rephrase the point of Antifragile (via Facebook) and put some clarity in the discussions. The idea is to be chance, “risk”, and uncertainty loving where chance, “risk” and uncertainty are beneficial, and risk averse in domains with ruin problems.

The ancients understood how both courage and prudence were virtues, and how there was no incompatibility between the two –simply they didn’t apply to the same domain. (More on that, soon).

The “verbalistic” takes over rather quickly. Many people don’t nuance risk properly, especially when educated: they conflate it with variations and think that *exposure to ruin* and *risk taking* belong to the same category. They are not the same animal. Concave is not convex, fragile is not antifragile; fat tails are not thin tails, etc.

What I just wrote seems trivial, but if you take a look at the not yet dismissed “scholarly” but in fact verbalistic and verbose literature (Cass Susstein-style, particularly about “nudging”), it seems largely resting on ill-defined terms and conflated concepts. We keep seeing bigwigs conflating Ebola with falling from ladders, GMOs with agriculture, etc., leading to misdefinition of rationality.

Just a brief stop for some clarity. Have a nice weekend.

People can only be social friends if (via Facebook) they don’t ty to outsmart one another. Indeed, the classical art of conversation is to avoid any imbalance as in Baldassare Castiglione’s Book of the Courtier: people need to be equal, at least for the purpose of the conversation, otherwise it fails. It has to be hierarchy free and equal in contribution. You’d rather have dinner with your friends than with your professor, unless of course your professor understands “the art” of the conversation.

Indeed, one can generalize and define a community as a space within which many rules of competition and hierarchy are lifted, where the collective prevails over one’s interest. Of course there will be tension with the outside, but that’s another discussion. This idea of competition lifted within a group or a tribe was the idea of the late Elenor Ostrom.

Friends, Ralph Nader called me recently (via Facebook) to warn me that I was going to be subjected to a smear campaign by Monsanto and friends, throwing anything they can to undermine my credibility, “throwing everything except the kitchen sink”. They care so much about their business there is nothing they wouldn’t throw at me. Nothing. He, himself, was subjected to a nasty smear campaign by GM fifty years ago.

Fughedabout the “victim” business. And it is not about enemies building you up, that’s not the point. There a *real thrill* feeling that you are risking something for your ideas. The more risk, the more skin-in-the-game, the more thrill.

The more they attack you, the more skin-in-the-game, the more you feel honorable. I cannot describe the sentiment: all I can say is that it is the exact opposite of shame.

Thanks all for the help, (via Facebook) the persistence, and the unwavering fight against BS vending. Looks like our precautionary principle paper was used as back-up for the decision by the supreme court of the Philippines against GMOs.

People get rigorous arguments; trying to repress truth and logic is like trying to keep a balloon under water, or Fat Tony away from the fridge.

Looks like a combination of persistence and … f*** you money (which I repeat is is not about money but the moral attitude towards bullying authorities) works.
