Skin in the Game

by Nassim Nicholas Taleb

  The IYI has been wrong, historically, about Stalinism, Maoism, GMOs, Iraq, Libya, Syria, lobotomies, urban planning, low carbohydrate diets, gym machines, behaviorism, trans-fats, Freudianism, portfolio theory, linear regression, HFCS (High-Fructose Corn Syrup), Gaussianism, Salafism, dynamic stochastic equilibrium modeling, housing projects, marathon running, selfish genes, election-forecasting models, Bernie Madoff (pre-blowup), and p-values. But he is still convinced that his current position is right.*1

  NEVER GOTTEN DRUNK WITH RUSSIANS

  The IYI joins a club to get travel privileges; if he is a social scientist, he uses statistics without knowing how they are derived (like Steven Pinker and psycholophasters in general); when in the United Kingdom, he goes to literary festivals and eats cucumber sandwiches, taking small bites at a time; he drinks red wine with steak (never white); he used to believe that dietary fat was harmful and has now completely reversed himself (information in both cases is derived from the same source); he takes statins because his doctor told him to do so; he fails to understand ergodicity, and, when explained to him, he forgets about it soon after; he doesn’t use Yiddish words even when talking business; he studies grammar before speaking a language; he has a cousin who worked with someone who knows the Queen; he has never read Frédéric Dard, Libanius Antiochus, Michael Oakeshott, John Gray, Ammianus Marcellinus, Ibn Battuta, Saadia Gaon, or Joseph de Maistre; he has never gotten drunk with Russians; he never drinks to the point where he starts breaking glasses (or, preferably, chairs); he doesn’t even know the difference between Hecate and Hecuba (which in Brooklynese is “can’t tell sh**t from shinola”); he doesn’t know that there is no difference between “pseudointellectual” and “intellectual” in the absence of skin in the game; he has mentioned quantum mechanics at least twice in the past five years in conversations that had nothing to do with physics.

  The IYI likes to use buzzwords from philosophy of science when discussing unrelated phenomena; he goes two or three levels too theoretical for a given problem.

  TO CONCLUDE

  The Intellectual Yet Idiot knows at any given point in time what his words or actions are doing to his reputation.

  But a much easier marker: he doesn’t even deadlift.*2

  POSTSCRIPT

  From the reactions to this chapter (which was posted before the presidential elections of 2016), I discovered that the typical IYI has difficulty, when reading, in differentiating between the satirical and the literal.

  Next, we stop the satirical and return to the main book with the sooooo misunderstood topic of economic inequality. By IYIs.

  *1 Pareto’s comments are harsher than mine on this topic.

  *2 Also the IYI thinks this criticism of IYIs means “everybody is an idiot,” not realizing that their group represents, as we said, a tiny minority—but they don’t like their sense of entitlement to be challenged, and although they treat the rest of humans as inferiors, they don’t like it when the water hose is turned to the opposite direction (what the French call arroseur arrosé). For instance, the economist and psycholophaster Richard Thaler, partner of the dangerous GMO advocate übernudger Cass Sunstein, interpreted this piece as saying that “there are not many non-idiots not called Taleb,” not realizing that people like him are less than 1 percent or even less than one-tenth of 1 percent of the population.

  The static and the dynamic—How to go bankrupt and be loved by the many—Piketty’s equals

  INEQUALITY VS. INEQUALITY

  There is inequality and inequality.

  The first is the inequality people tolerate, such as one’s understanding compared to that of people deemed heroes, say, Einstein, Michelangelo, or the recluse mathematician Grisha Perelman, in comparison to whom one has no difficulty acknowledging a large surplus. This applies to entrepreneurs, artists, soldiers, heroes, the singer Bob Dylan, Socrates, the current local celebrity chef, some Roman Emperor of good repute, say, Marcus Aurelius; in short, those for whom one can naturally be a “fan.” You may like to imitate them, you may aspire to be like them, but you don’t resent them.

  The second is the inequality people find intolerable because the subject appears to be just a person like you, except that he has been playing the system, and getting himself into rent-seeking, acquiring privileges that are not warranted—and although he has something you would not mind having (which may include his Russian girlfriend), you cannot possibly become a fan. The latter category includes bankers, bureaucrats who get rich, former senators shilling for the evil firm Monsanto, clean-shaven chief executives who wear ties, and talking heads on television making outsized bonuses. You don’t just envy them; you take umbrage at their fame, and the sight of their expensive or even semi-expensive car triggers some feeling of bitterness. They make you feel smaller.*1

  There may be something dissonant in the spectacle of a rich slave.

  The author Joan C. Williams, in an insightful article, explains that the American working class is impressed by the rich, as role models—something people in the media, who communicate with one another but rarely with subjects in the real world, don’t realize, as they impart normative ideas to people (“this is how they should think”). Michèle Lamont, the author of The Dignity of Working Men, cited by Williams, did a systematic interview of blue-collar Americans and found a resentment of high-paid professionals but, unexpectedly, not of the rich.

  It is safe to say that the American public—actually all publics—despises people who make a lot of money on a salary, or, rather, salarymen who make a lot of money. This is indeed generalized to other countries: a few years ago the Swiss, of all people, ran a referendum for a law capping salaries of managers to a set multiple of the lowest wage. The law didn’t pass, but the fact that they thought in these terms is rather significant. For the same Swiss hold rich entrepreneurs, and people who have derived their celebrity by other means, in some respect.

  Further, in countries where wealth comes from rent-seeking, political patronage, or regulatory capture (which, I remind the reader, is how the powerful and the insiders use regulation to scam the public, or red tape to slow down competition), wealth is seen as zero-sum.*2 What Peter gets is extracted from Paul. Someone getting rich is doing so at other people’s expense. In countries such as the U.S., where wealth can come from destruction, people can easily see that someone getting rich is not taking dollars from your pocket; odds are he is even putting some in yours. On the other hand, inequality, by definition, is zero sum.

  In this chapter, I will propose that what people resent—or should resent—is the person at the top who has no skin in the game, that is, because he doesn’t bear his allotted risk, he is immune to the possibility of falling from his pedestal, exiting his income or wealth bracket, and waiting in line outside the soup kitchen. Again, on that account, the detractors of Donald Trump, when he was still a candidate, not only misunderstood the value of scars as risk signaling, but they also failed to realize that, by advertising his episode of bankruptcy and his personal losses of close to a billion dollars, he removed the resentment (the second type of inequality) people may have had toward him. There is something respectable in losing a billion dollars, provided it is your own money.

  In addition, someone without skin in the game—say, a corporate executive with upside and no financial downside (the type to speak clearly in meetings)—is paid according to some metrics that do not necessarily reflect the health of his company; these he can manipulate, hide risks, get the bonus, then retire (or go do the same thing at another company) and blame his successor for subsequent results.

  We will also, in the process, redefine inequality and put the notion on more rigorous grounds. But we first need to introduce the difference between two types of approaches, the static and the dynamic, as skin in the game can transform one type of inequality into another.

  Take also the two following remarks:

 
True equality is equality in probability.

  and

  Skin in the game prevents systems from rotting.

  THE STATIC AND THE DYNAMIC

  Visibly, a problem with economists (particularly those who never took risk) is that they have mental difficulties with things that move and are unable to consider that things that move have different attributes from things that don’t. That’s the reason complexity theory and fat tails (which we will explain a few pages down) are foreign to most of them; they also have (severe) difficulties with the mathematical and conceptual intuitions required for deeper probability theory. Blindness to ergodicity, which we will begin to define a few paragraphs down, is indeed in my opinion the best marker separating a genuine scholar who understands something about the world from an academic hack who partakes of ritualistic paper writing.

  A few definitions:

  Static inequality is a snapshot view of inequality; it does not reflect what will happen to you in the course of your life.

  Consider that about 10 percent of Americans will spend at least a year in the top 1 percent, and more than half of all Americans will spend a year in the top 10 percent.*3 This is visibly not the same for the more static—but nominally more equal—Europe. For instance, only 10 percent of the wealthiest five hundred American people or dynasties were so thirty years ago; more than 60 percent on the French list are heirs and a third of the richest Europeans were the richest centuries ago. In Florence, it was just revealed that things are even worse: the same handful of families have kept the wealth for five centuries.

  Dynamic (ergodic) inequality takes into account the entire future and past life.

  You do not create dynamic equality just by raising the level of those at the bottom, but rather by making the rich rotate—or by forcing people to incur the possibility of creating an opening.

  The way to make society more equal is by forcing (through skin in the game) the rich to be subjected to the risk of exiting from the 1 percent.*4

  Our condition here is stronger than mere income mobility. Mobility means that someone can become rich. The no-absorbing-barrier condition means that someone who is rich should never be certain to stay rich.

  Now, even more mathematically,

  Dynamic equality is what restores ergodicity, making time and ensemble probabilities substitutable.

  Let me explain ergodicity—something that we said is foreign to the intelligentsia. Chapter 19 at the back of the book goes into the details; it cancels most crucial psychological experiments related to probability and rationality. The intuition for now is as follows. Take a cross-sectional picture of the U.S. population. You have, say, a minority of millionaires in the one percent, some overweight, some tall, some humorous. You also have a high majority of people in the lower middle class, yoga instructors, baking experts, gardening consultants, spreadsheet theoreticians, dancing advisors, and piano repairpersons—plus of course the Spanish grammar specialist. Take the percentages of each income or wealth bracket (note that the inequality of income is typically flatter than that of wealth). Perfect ergodicity means that each one of us, should he live forever, would spend a proportion of time in the economic conditions of the entire cross-section: out of, say, a century, an average of sixty years in the lower middle class, ten years in the upper middle class, twenty years in the blue-collar class, and perhaps one single year in the one percent.*5, *6

  The exact opposite of perfect ergodicity is an absorbing state. The term absorption is derived from particles that, when they hit an obstacle, get absorbed or stick to it. An absorbing barrier is like a trap, once in, you can’t get out, good or bad. A person gets rich by some process, then, having arrived, he stays rich. And if someone enters the lower middle class (from above), he will never have the chance to exit from it and become rich should he want to, of course—hence will be justified to resent the rich. You will notice that where the state is large, people at the top tend to have little downward mobility—in such places as France, the state is chummy with large corporations and protects their executives and shareholders from experiencing such descent; it even encourages their ascent.

  And no downside for some means no upside for the rest.

  PIKETTISM AND THE REVOLT OF THE MANDARIN CLASS*7

  There is a class often called the Mandarins, after the fictionalized memoirs of the French author Simone de Beauvoir, named after the scholars of the Ming dynasty (the high Chinese language is also called Mandarin). I have always been aware of their existence, but a salient—and pernicious—attribute came to me while observing the reactions of its members to the works of the French economist Thomas Piketty.

  Piketty followed Karl Marx by writing an ambitious book on capital. A friend gave me the book as a gift when it was still in French (and unknown outside France) because I find it commendable that people publish their original, nonmathematical work in social science in book format. The book, Capital in the Twenty-first Century, makes aggressive claims about the alarming rise of inequality, adding to it a theory of why capital tends to command too much return in relation to labor and how the absence of redistribution and dispossession might make the world collapse. Piketty’s theory about the increase in the return of capital in relation to labor is patently wrong, as anyone who has witnessed the rise of what is called the “knowledge economy” (or anyone who has had investments in general) knows.

  Clearly, when you say that inequality changes from year one to year two, you need to show that those who are at the top are the same people—something Piketty doesn’t do (remember that he is an economist and has trouble with things that move). But the problem doesn’t stop there. Soon, I discovered that—aside from deriving conclusions from static measures of inequality—the methods he used were flawed: Piketty’s tools did not match what he purported to show about the rise in inequality. There was no mathematical rigor. I soon wrote two articles (one in collaboration with Raphael Douady, another with Andrea Fontanari and Pasquale Cirillo, published in Physica A: Statistical Mechanics and Applications), about the measure of inequality that consists in taking the ownership of, say, the top 1 percent and monitoring its variations. The flaw is that if you take the inequality thus measured in Europe as a whole, you will find it is higher than the average inequality across component countries; the bias increases in severity with processes that deliver a high degree of inequality. All in all, the papers had enough theorems and proofs to make them about as ironclad a piece of work as one can have in science; although it was not necessary, I insisted on putting the results in theorem form because someone cannot contest a formally proved theorem without putting in question his own understanding of mathematics.

  The reason these errors were not known was because economists who work with inequality were not familiar with…inequality. Inequality is the disproportion of the role of the tail—rich people were in the tails of the distribution.*8 The more inequality in the system, the more the winner-take-all effect, the more we depart from the methods of thin-tailed Mediocristan (see Glossary) in which economists were trained. The wealth process is dominated by winner-take-all effects. Any form of control of the wealth process—typically instigated by bureaucrats—tends to lock people with privileges in their state of entitlement. So the solution is to allow the system to destroy the strong, something that works best in the United States.

  But there was something far, far more severe than a scholar being wrong.

  The problem is never the problem; it is how people handle it. What was worse than Piketty’s flaws was the discovery of how that Mandarin class operates. They got so prematurely excited by the “evidence” of the rise in inequality that their reactions were like fake news. Actually, they were fake news. Economists got so carried away; they praised Piketty for his “erudition” because he discussed Balzac and Jane Austen, the equivalent to hailing as a weight lifter someone sp
otted carrying a briefcase across Terminal B. And they completely ignored my results—and when they didn’t, it was to declare that I was “arrogant”(recall the strategy of using formal mathematics as a way to make it impossible to say you are wrong)—which is a form of scientific compliment. Even Paul Krugman (a currently famous economist and public intellectual) wrote, “If you think you’ve found an obvious hole, empirical or logical, in Piketty, you’re very probably wrong. He’s done his homework!” When I met him in person and pointed out the flaw to him, he evaded it—not necessarily out of malice, but most likely because probability and combinatorics eluded him, by his own admission.

  Now consider that the likes of Krugman and Piketty have no downside in their existence—lowering inequality brings them up in the ladder of life. Unless the university system or the French state goes bust, they will continue receiving their paychecks. The fellow you just saw in the steak restaurant dripping with gold chains is exposed to the risk of the soup kitchen, not them. Just as those who live by the sword die by the sword, those who earn their living taking risks will lose their livelihood taking risks.*9

  We’ve made a big deal out of Piketty here because the widespread enthusiasm for his book was representative of the behavior of that class of people who love to theorize and engage in false solidarity with the oppressed, while consolidating their privileges.

  COBBLER ENVIES COBBLER

  The reason regular people are not as acrimonious as the “intellectuals” and bureaucrats is because envy does not travel long distance or cross many social classes. Envy does not originate with the impoverished, concerned with the betterment of their condition, but with the clerical class. Simply, it looks like it was the university professors (who have “arrived”) and people who have permanent stability of income, in the form of tenure, governmental or academic, who bought heavily into Piketty’s argument. From conversations, I became convinced that people who counterfactual upwards (i.e., compare themselves to those richer) want to actively dispossess the rich. As with all communist movements, it is often the bourgeois or clerical classes who are the early adopters of revolutionary theories. So class envy doesn’t originate from a truck driver in South Alabama, but from a New York or Washington, D.C., Ivy League–educated IYI (say Paul Krugman or Joseph Stiglitz) with a sense of entitlement, upset some “less smart” persons are much richer.
