The distinction between these two sides is the divide that emerged between Taleb and Niederhoffer all those years ago in Connecticut. Niederhoffer’s hero is the nineteenth- century scientist Francis Galton. Niederhoffer called his eldest daughter Galt, and there is a full-length portrait of Galton in his library. Galton was a statistician and a social scientist (and a geneticist and a meteorologist), and if he was your hero, you believed that by marshaling empirical evidence, by aggregating data points, you could learn whatever it was you needed to know. Taleb’s hero, on the other hand, is Karl Popper, who said that you could not know with any certainty that a proposition was true; you could only know that it was not true. Taleb makes much of what he learned from Niederhoffer, but Niederhoffer insists that his example was wasted on Taleb. “In one of his cases, Rumpole of the Bailey talked about being tried by the bishop who doesn’t believe in God,” Niederhoffer says. “Nassim is the empiricist who doesn’t believe in empiricism.” What is it that you claim to learn from experience, if you believe that experience cannot be trusted? Today, Niederhoffer makes a lot of his money selling options, and more often than not the person to whom he sells those options is Nassim Taleb. If one of them is up a dollar one day, in other words, that dollar is likely to have come from the other. The teacher and pupil have become predator and prey.

Years ago, Nassim Taleb worked at the investment bank First Boston, and one of the things that puzzled him was what he saw as the mindless industry of the trading floor. A trader was supposed to come in every morning and buy and sell things, and on the basis of how much money he made buying and selling he was given a bonus. If he went too many weeks without showing a profit, his peers would start to look at him funny, and if he went too many months without showing a profit, he would be gone. The traders were for the most part well educated and wore Savile Row suits and Ferragamo ties. They dove into the markets with a frantic urgency. They read the Wall Street Journal closely and gathered around the television to catch breaking news. “The Fed did this, the Prime Minister of Spain did that,” Taleb recalls. “The Italian Finance Minister says there will be no competitive devaluation, this number is higher than expected, Abby Cohen just said this.” It was a scene that Taleb did not understand.
“He was always so conceptual about what he was doing,” says Howard Savery, who was Taleb’s assistant at the French bank Indosuez in the 1980s. “He used to drive our floor trader (his name was Tim) crazy. Floor traders are used to precision: “Sell a hundred futures at eighty-seven.” Nassim would pick up the phone and say, “Tim, sell some.” And Tim would say, “How many?” And he would say, “Oh, a social amount.” It was like saying, “I don’t have a number in mind, I just know I want to sell.” There would be these heated arguments in French, screaming arguments. Then everyone would go out to dinner and have fun. Nassim and his group had this attitude that we’re not interested in knowing what the new trade number is. When everyone else was leaning over their desks, listening closely to the latest figures, Nassim would make a big scene of walking out of the room.”
At Empirica, then, there are no Wall Street Journals to be found. There is very little active trading, because the options that the fund owns are selected by computer. Most of those options will be useful only if the market does something dramatic, and, of course, on most days the market doesn’t. So the job of Taleb and his team is to wait and to think. They analyze the company’s trading policies, back-test various strategies, and construct ever more sophisticated computer models of options pricing. Danny, in the corner, occasionally types things into the computer. Pallop looks dreamily off into the distance. Spitznagel takes calls from traders, and toggles back and forth between screens on his computer. Taleb answers e-mails and calls one of the firm’s brokers in Chicago, affecting, as he does, the kind of Brooklyn accent that people from Brooklyn would have if they were actually from northern Lebanon: “Howyoudoin?” It is closer to a classroom than to a trading floor.
“Pallop, did you introspect?” Taleb calls out as he wanders back in from lunch. Pallop is asked what his PhD is about. “Pretty much this,” he says, waving a languid hand around the room.
“It looks like we will have to write it for him,” Taleb chimes in, “because Pollop is very lazy.”
What Empirica has done is to invert the traditional psychology of investing. You and I, if we invest conventionally in the market, have a fairly large chance of making a small amount of money in a given day from dividends or interest or the general upward trend of the market. We have almost no chance of making a large amount of money in one day, and there is a very small, but real, possibility that if the market collapses we could blow up. We accept that distribution of risks because, for fundamental reasons, it feels right. In the book that Pallop was reading by Kahneman and Tversky, for example, there is a description of a simple experiment, where a group of people were told to imagine that they had $300. They were then given a choice between (a) receiving another $100 or (b) tossing a coin, where if they won they got $200 and if they lost they got nothing. Most of us, it turns out, prefer (a) to (b). But then Kahneman and Tversky did a second experiment. They told people to imagine that they had $500 and then asked them if they would rather (c) give up $100 or (d) toss a coin and pay $200 if they lost and nothing at all if they won. Most of us now prefer (d) to (c). What is interesting about those four choices is that, from a probabilistic standpoint, they are identical. Nonetheless, we have strong preferences among them. Why? Because we’re more willing to gamble when it comes to losses, but are risk averse when it comes to our gains. That’s why we like small daily winnings in the stock market, even if that requires that we risk losing everything in a crash.
At Empirica, by contrast, every day brings a small but real possibility that they’ll make a huge amount of money in a day; no chance that they’ll blow up; and a very large possibility that they’ll lose a small amount of money. All those dollar, and fifty-cent, and nickel options that Empirica has accumulated, few of which will ever be used, soon begin to add up. By looking at a particular column on the computer screens showing Empirica’s positions, anyone at the firm can tell you precisely how much money Empirica has lost or made so far that day. At 11:30 a.m., for instance, they had recovered just 28 percent of the money they had spent that day on options. By 12:30, they had recovered 40 percent, meaning that the day was not yet half over and Empirica was already in the red to the tune of several hundred thousand dollars. The day before that, it had made back 85 percent of its money; the day before that, 48 percent; the day before that, 65 percent; and the day before that also 65 percent; and, in fact, with a few notable exceptions — like the few days when the market reopened after September 11 — Empirica has done nothing but lose money since last April. “We cannot blow up, we can only bleed to death,” Taleb says, and bleeding to death, absorbing the pain of steady losses, is precisely what human beings are hardwired to avoid. “Say you’ve got a guy who is long on Russian bonds,” Savery says. “He’s making money every day. One day, lightning strikes and he loses five times what he made. Still, on three hundred and sixty-four out of three hundred and sixty-five days he was very happily making money. It’s much harder to be the other guy, the guy losing money three hundred and sixty-four days out of three hundred and sixty-five, because you start questioning yourself. Am I ever going to make it back? Am I really right? What if it takes ten years? Will I even be sane ten years from now?” What the normal trader gets from his daily winnings is feedback, the pleasing illusion of progress. At Empirica, there is no feedback. “It’s like you’re playing the piano for ten years and you still can’t play ‘Chopsticks,’ ” Spitznagel say, “and the only thing you have to keep you going is the belief that one day you’ll wake up and play like Rachmaninoff.” Was it easy knowing that Niederhoffer — who represented everything they thought was wrong — was out there getting rich while they were bleeding away? Of course it wasn’t. If you watched Taleb closely that day, you could see
the little ways in which the steady drip of losses takes a toll. He glanced a bit too much at the Bloomberg. He leaned forward a bit too often to see the daily loss count. He succumbs to an array of superstitious tics. If the going is good, he parks in the same space every day; he turned against Mahler because he associates Mahler with the last year’s long dry spell. “Nassim says all the time that he needs me there, and I believe him,” Spitznagel says. He is there to remind Taleb that there is a point to waiting, to help Taleb resist the very human impulse to abandon everything and stanch the pain of losing. “Mark is my cop,” Taleb says. So is Pallop: he is there to remind Taleb that Empirica has the intellectual edge.
“The key is not having the ideas but having the recipe to deal with your ideas,” Taleb says. “We don’t need moralizing. We need a set of tricks.” His trick is a protocol that stipulates precisely what has to be done in every situation. “We built the protocol, and the reason we did was to tell the guys, Don’t listen to me, listen to the protocol. Now, I have the right to change the protocol, but there is a protocol to changing the protocol. We have to be hard on ourselves to do what we do. The bias we see in Niederhoffer we see in ourselves.” At the quant dinner, Taleb devoured his roll, and as the busboy came around with more rolls Taleb shouted out, “No, no!” and blocked his plate. It was a never-ending struggle, this battle between head and heart. When the waiter came around with wine, he hastily covered the glass with his hand. When the time came to order, he asked for steak frites — “without the frites, please!” — and then immediately tried to hedge his choice by negotiating with the person next to him for a fraction of his frites.
The psychologist Walter Mischel has done a series of experiments where he puts a young child in a room and places two cookies in front of him, one small and one large. The child is told that if he wants the small cookie he need only ring a bell and the experimenter will come back into the room and give it to him. If he wants the better treat, though, he has to wait until the experimenter returns on his own, which might be anytime in the next twenty minutes. Mischel has videotapes of six-year-olds sitting in the room by themselves, staring at the cookies, trying to persuade themselves to wait. One girl starts to sing to herself. She whispers what seems to be the instructions — that she can have the big cookie if she can only wait. She closes her eyes. Then she turns her back on the cookies. Another little boy swings his legs violently back and forth, and then picks up the bell and examines it, trying to do anything but think about the cookie he could get by ringing it. The tapes document the beginnings of discipline and self-control — the techniques we learn to keep our impulses in check — and to watch all the children desperately distracting themselves is to experience the shock of recognition: that’s Nassim Taleb!
There is something else as well that helps to explain Taleb’s resolve — more than the tics and the systems and the self-denying ordinances. It happened a year or so before he went to see Niederhoffer. Taleb had been working as a trader at the Chicago Mercantile Exchange, and he’d developed a persistently hoarse throat. At first, he thought nothing of it: a hoarse throat was an occupational hazard of spending every day in the pit. Finally, when he moved back to New York, he went to see a doctor, in one of those Upper East Side prewar buildings with a glamorous facade. Taleb sat in the office, staring out at the plain brick of the courtyard, reading the medical diplomas on the wall over and over, waiting and waiting for the verdict. The doctor returned and spoke in a low, grave voice: “I got the pathology report. It’s not as bad as it sounds.” But, of course, it was: he had throat cancer. Taleb’s mind shut down. He left the office. It was raining outside. He walked and walked and ended up at a medical library. There he read frantically about his disease, the rainwater forming a puddle under his feet. It made no sense. Throat cancer was the disease of someone who has spent a lifetime smoking heavily. But Taleb was young, and he barely smoked at all. His risk of getting throat cancer was something like one in a hundred thousand, almost unimaginably small. He was a black swan! The cancer is now beaten, but the memory of it is also Taleb’s secret, because once you have been a black swan — not just seen one but lived and faced death as one — it becomes easier to imagine another on the horizon.
As the day came to an end, Taleb and his team turned their attention once again to the problem of the square root of n. Taleb was back at the whiteboard. Spitznagel was looking on. Pallop was idly peeling a banana. Outside, the sun was beginning to settle behind the trees. “You do a conversion to p1 and p2,” Taleb said. His marker was once again squeaking across the whiteboard. “We say we have a Gaussian distribution, and you have the market switching from a low-volume regime to a high-volume. P21. P22. You have your igon value.” He frowned and stared at his handiwork. The markets were now closed. Empirica had lost money, which meant that somewhere off in the woods of Connecticut Niederhoffer had no doubt made money. That hurt, but if you steeled yourself and thought about the problem at hand, and kept in mind that someday the market would do something utterly unexpected because in the world we live in something utterly unexpected always happens, then the hurt was not so bad. Taleb eyed his equations on the whiteboard and arched an eyebrow. It was a very difficult problem. “Where is Dr. Wu? Should we call in Dr. Wu?”

A year after Nassim Taleb came to visit him, Victor Niederhoffer blew up. He sold a very large number of options on the S&P index, taking millions of dollars from other traders in exchange for promising to buy a basket of stocks from them at current prices, if the market ever fell. It was an unhedged bet, or what was called on Wall Street a naked put, meaning that he bet everyone on one outcome: he bet in favor of the large probability of making a small amount of money, and against the small probability of losing a large amount of money — and he lost. On October 27, 1997, the market plummeted 8 percent, and all of the many, many people who had bought those options from Niederhoffer came calling all at once, demanding that he buy back their stocks at pre-crash prices. He ran through $130,000,000 — his cash reserves, his savings, his other stocks — and when his broker came and asked for still more, he didn’t have it. In a day, one of the most successful hedge funds in America was wiped out. Niederhoffer had to shut down his firm. He had to mortgage his house. He had to borrow money from his children. He had to call Sotheby’s and sell his prized silver collection — the massive nineteenth-century Brazilian “sculptural group of victory” made for the Visconde De Figueirdeo, the massive silver bowl designed in 1887 by Tiffany & Co. for the James Gordon Bennett Cup yacht race, and on and on. He stayed away from the auction. He couldn’t bear to watch.
“It was one of the worst things that has ever happened to me in my life, right up there with the death of those closest to me,” Niederhoffer said recently. It was a Saturday in March, and he was in the library of his enormous house. Two weary-looking dogs wandered in and out. He is a tall man, an athlete, thick through the upper body and trunk, with a long, imposing face and baleful, hooded eyes. He was shoeless. One collar on his shirt was twisted inward, and he looked away as he talked. “I let down my friends. I lost my business. I was a major money manager. Now I pretty much have had to start from ground zero.” He paused. “Five years have passed. The beaver builds a dam. The river washes it away, so he tries to build a better foundation, and I think I have. But I’m always mindful of the possibility of more failures.” In the distance, there was a knock on the door. It was a man named Milton Bond, an artist who had come to present Niederhoffer with a painting he had done of Moby Dick ramming the Pequod. It was in the folk-art style that Niederhoffer likes so much, and he went to meet Bond in the foyer, kneeling down in front of the painting as Bond unwrapped it. Niederhoffer has other paintings of the Pequod in his house, and paintings of the Essex, the ship on which Melville’s story was based. In his office, on a prominent wall, is a painting of the Titanic. They were, he said, his way of staying humble. “One of the reasons I’ve paid lots of attention to the Essex is that it turns out tha
t the captain of the Essex, as soon as he got back to Nantucket, was given another job,” Niederhoffer said. “They thought he did a good job in getting back after the ship was rammed. The captain was asked, ‘How could people give you another ship?’ And he said, ‘I guess on the theory that lightning doesn’t strike twice.’ It was a fairly random thing. But then he was given the other ship, and that one foundered, too. Got stuck in the ice. At that time, he was a lost man. He wouldn’t even let them save him. They had to forcibly remove him from the ship. He spent the rest of his life as a janitor in Nantucket. He became what on Wall Street they call a ghost.” Niederhoffer was back in his study now, his lanky body stretched out, his feet up on the table, his eyes a little rheumy. “You see? I can’t afford to fail a second time. Then I’ll be a total washout. That’s the significance of the Pequod.”
A month or so before Niederhoffer blew up, Taleb had dinner with him at a restaurant in Westport, and Niederhoffer told him that he had been selling naked puts. You can imagine the two of them across the table from each other, Niederhoffer explaining that his bet was an acceptable risk, that the odds of the market going down so heavily that he would be wiped out were minuscule, and Taleb listening and shaking his head, and thinking about black swans. “I was depressed when I left him,” Taleb said. “Here is a guy who goes out and hits a thousand backhands. He plays chess like his life depends on it. Here is a guy who, whatever he wants to do when he wakes up in the morning, he ends up doing better than anyone else. Whatever he wakes up in the morning and decides to do, he did better than anyone else. I was talking to my hero . . .” This was the reason Taleb didn’t want to be Niederhoffer when Niederhoffer was at his height — the reason he didn’t want the silver and the house and the tennis matches with George Soros. He could see all too clearly where it all might end up. In his mind’s eye, he could envision Niederhoffer borrowing money from his children, and selling off his silver, and talking in a hollow voice about letting down his friends, and Taleb did not know if he had the strength to live with that possibility. Unlike Niederhoffer, Taleb never thought he was invincible. You couldn’t if you had watched your homeland blow up, and had been the one person in a hundred thousand who gets throat cancer, and so for Taleb there was never any alternative to the painful process of insuring himself against catastrophe.
