Nassim Taleb Quotes

The three most harmful addictions are heroin, carbohydrates, and a monthly salary.

Love without sacrifice is like theft

Missing a train is only painful if you run after it! Likewise, not matching the idea of success others expect from you is only painful if that’s what you are seeking.

A Stoic is someone who transforms fear into prudence, pain into transformation, mistakes into initiation, and desire into undertaking.

Charm is the ability to insult people without offending them; nerdiness the reverse

Half of the people lie with their lips; the other half with their tears

The psychologist Gerd Gigerenzer has a simple heuristic. Never ask the doctor what you should do. Ask him what he would do if he were in your place. You would be surprised at the difference

Heroes are heroes because they are heroic in behavior, not because they won or lost.

What I learned on my own I still remember

The difference between technology and slavery is that slaves are fully aware that they are not free

If you want to annoy a poet, explain his poetry.

When you develop your opinions on the basis of weak evidence, you will have difficulty interpreting subsequent information that contradicts these opinions, even if this new information is obviously more accurate.

It has been more profitable for us to bind together in the wrong direction than to be alone in the right one. Those who have followed the assertive idiot rather than the introspective wise person have passed us some of their genes. This is apparent from a social pathology: psychopaths rally followers.

They will envy you for your success, your wealth, for your intelligence, for your looks, for your status - but rarely for your wisdom.

Things always become obvious after the fact

Difficulty is what wakes up the genius

Wit seduces by signaling intelligence without nerdiness.

People focus on role models; it is more effective to find antimodels - people you don't want to resemble when you grow up

They think that intelligence is about noticing things are relevant (detecting patterns); in a complex world, intelligence consists in ignoring things that are irrelevant (avoiding false patterns)

Antifragility is beyond resilience or robustness. The resilient resists shocks and stays the same; the antifragile gets better.

Remember that you are a Black Swan.

It is my great hope someday, to see science and decision makers rediscover what the ancients have always known. Namely that our highest currency is respect.

You may never know what type of person someone is unless they are given opportunities to violate moral or ethical codes.

Few understand that procrastination is our natural defense, letting things take care of themselves and exercise their antifragility; it results from some ecological or naturalistic wisdom, and is not always bad -- at an existential level, it is my body rebelling against its entrapment. It is my soul fighting the Procrustean bed of modernity.

A prophet is not someone with special visions, just someone blind to most of what others see

The problem with experts is that they do not know what they do not know

The best way to measure the loss of intellectual sophistication - this "nerdification," to put it bluntly - is in the growing disappearance of sarcasm, as mechanic minds take insults a bit too literally.

I am, at the Fed level, libertarian; at the state level, Republican; at the local level, Democrat; and at the family and friends level, a socialist. If that saying doesn’t convince you of the fatuousness of left vs. right labels, nothing will.

Suckers try to win arguments, nonsuckers try to win.

If you have more than one reason to do something (choose a doctor or veterinarian, hire a gardener or an employee, marry a person, go on a trip), just don’t do it. It does not mean that one reason is better than two, just that by invoking more than one reason you are trying to convince yourself to do something. Obvious decisions (robust to error) require no more than a single reason.

Academia is to knowledge what prostitution is to love; close enough on the surface but, to the nonsucker, not exactly the same thing

The curse of modernity is that we are increasingly populated by a class of people who are better at explaining than understanding, or better at explaining than doing.

The curious mind embraces science; the gifted and sensitive, the arts; the practical, business; the leftover becomes an economist

The writer Umberto Eco belongs to that small class of scholars who are encyclopedic, insightful, and nondull. He is the owner of a large personal library (containing thirty thousand books), and separates visitors into two categories: those who react with “Wow! Signore, professore dottore Eco, what a library you have ! How many of these books have you read?” and the others - a very small minority - who get the point that a private library is not an ego-boosting appendage but a research tool. Read books are far less valuable than unread ones. The library should contain as much of what you don’t know as your financial means, mortgage rates and the currently tight real-estate market allows you to put there. You will accumulate more knowledge and more books as you grow older, and the growing number of unread books on the shelves will look at you menancingly. Indeed, the more you know, the larger the rows of unread books. Let us call this collection of unread books an antilibrary.

The irony of the process of thought control: the more energy you put into trying to control your ideas and what you think about, the more your ideas end up controlling you.

Only the autodidacts are free.

Modernity: we created youth without heroism, age without wisdom, and life without grandeur

Abundance is harder for us to handle than scarcity.

Meditation is a way to be narcissistic without hurting anyone

Karl Marx, a visionary, figured out that you can control a slave much better by convincing him he is an employee.

We tend to use knowledge as therapy.

I want to live happily in a world I don’t understand.

If you hear a "prominent" economist using the word 'equilibrium,' or 'normal distribution,' do not argue with him; just ignore him, or try to put a rat down his shirt.

My biggest problem with modernity may lie in the growing separation of the ethical and the legal

Ideas come and go, stories stay.

When you beat up someone physically, you get excercise and stress relief; when you assault him verbally on the Internet, you just harm yourself.

This is the tragedy of modernity: as with neurotically overprotective parents, those trying to help are often hurting us the most.

Doctors most commonly get mixed up between absence of evidence and evidence of abense

What matters isn’t what a person has or doesn’t have; it is what he or she is afraid of losing.

I will repeat the following until I am hoarse: it is contagion that determines the fate of a theory in social science, not its validity.

Read books are far less valuable than unread ones. The library should contain as much of what you do not know as your financial means, mortgage rates, and the currently tight real-estate market alow you to put there.

The problem of knowledge is that there are many more books on birds written by ornithologists than books on birds written by birds and books on ornithologists written by birds

Most humans manage to squander their free time, as free time makes them dysfunctional, lazy, and unmotivated—the busier they get, the more active they are at other tasks.

The inability to predict outliers implies the inability to predict the course of history

If an emotion can't change the condition or the situation you're dealing with, it is likely an unhelpful emotion. Or, quite possibly, a destructive one. But it's what I feel. Right, no one said anything about not feeling it. No one said you can't ever cry. Forget "manliness." If you need to take a moment, by all means, go ahead. Real strength lies in the control or, as Nassim Taleb put it, the domestication of one's emotions, not in pretending they don't exist.

To bankrupt a fool, give him information.

He who has never sinned is less reliable than he who has only sinned once.

Probability is not a mere computation of odds on the dice or more complicated variants; it is the acceptance of the lack of certainty in our knowledge and the development of methods for dealing with our ignorance.

What organized dating sites fail to understand is that the people are far more interesting in what they don't say about themselves.

Categorizing is necessary for humans, but it becomes pathological when the category is seen as definitive, preventing people from considering the fuzziness of boundaries,

Courage is the only virtue you cannot fake.

The simpler, the better. Complications lead to multiplicative chains of unanticipated effects.

Those who talk should do and only those who do should talk.

The difference between successful people and really successful people is that really successful people say no to almost everything,

More data—such as paying attention to the eye colors of the people around when crossing the street—can make you miss the big truck.

Some things benefit from shocks; they thrive and grow when exposed to volatility, randomness, disorder, and stressors and love adventure, risk, and uncertainty.

If you survive until tomorrow, it could mean that either a) you are more likely to be immortal or b) that you are closer to death.

The imagination of the genius vastly surpasses his intellect; the intellect of the academic vastly surpasses his imagination

Never ask anyone for their opinion, forecast, or recommendation. Just ask them what they have—or don’t have—in their portfolio.

No matter how sophisticated our choices, how good we are at dominating the odds, randomness will have the last word.

The classical man's worst fear was inglorious death; the modern man's worst fear is just death

Prediction, not narration, is the real test of our understanding of the world.

A mistake is not something to be determined after the fact, but in light of the information available until that point

If there is something in nature you don't understand, odds are it makes sense in a deeper way that is beyond your understanding. So there is a logic to natural things that is much superior to our own. Just as there is a dichotomy in law: 'innocent until proven guilty' as opposed to 'guilty until proven innocent', let me express my rule as follows: what Mother Nature does is rigorous until proven otherwise; what humans and science do is flawed until proven otherwise.

Modernity has replaced ethics with legalese, and the law can be gamed with a good lawyer.

If you do not take risks for your opinion, you are nothing.

Curiosity is antifragile, like an addiction, and is magnified by attempts to satisfy it—books have a secret mission and ability to multiply, as everyone who has wall-to-wall bookshelves knows well.

Work destroys your soul by stealthily invading your brain during the hours not officially spent working; be selective about professions.

You can define a free person precisely as someone whose fate is not centrally or directly dependent on peer assessment.

Let me be more aggressive: we are largely better at doing than we are at thinking, thanks to antifragility. I’d rather be dumb and antifragile than extremely smart and fragile, any time.

Believe me, it is tough to deal with the social consequences of the appearance of continuous failure. We are social animals; hell is other people.

that if you need something urgently done, give the task to the busiest (or second busiest) person in the office.

We are quick to forget that just being alive is an extraordinary piece of good luck, a remote event, a chance occurrence of monstrous proportions.

Never ask a man if he is from Sparta: If he were, he would have let you know such an important fact - and if he were not, you could hurt his feelings.

Those who do not think that employment is systemic slavery are either blind or employed.

If you want to get an idea of a friend's temperament, ethics, and personal elegance, you need to look at him under the tests of severe circumstances, not under the regular rosy glow of daily life.

true humility is when you can surprise yourself more than others; the rest is either shyness or good marketing

Bureaucracy is a construction by which a person is conveniently separated from the consequences of his or her actions.

Those who were unlucky in life in spite of their skills would eventually rise. The lucky fool might have benefited from some luck in life; over the longer run he would slowly converge to the state of a less-lucky idiot. Each one would revert to his long-term properties.

The best way to verify that you are alive is by checking if you like variations. Remember that food would not have a taste if it weren’t for hunger; results are meaningless without effort, joy without sadness, convictions without uncertainty, and an ethical life isn’t so when stripped of personal risks.

The minute I was bored with a book or a subject I moved to another one, instead of giving up on reading altogether - when you are limited to the school material and you get bored, you have a tendency to give up and do nothing or play hooky out of discouragement. The trick is to be bored with a specific book, rather than with the act of reading. So the number of the pages absorbed could grow faster than otherwise. And you find gold, so to speak, effortlessly, just as in rational but undirected trial-and-error-based research. It is exactly like options, trial and error, not getting stuck, bifurcating when necessary but keeping a sense of broad freedom and opportunism. Trial and error is freedom.

Some can be more intelligent than others in a structured environment—in fact school has a selection bias as it favors those quicker in such an environment, and like anything competitive, at the expense of performance outside it. Although I was not yet familiar with gyms, my idea of knowledge was as follows. People who build their strength using these modern expensive gym machines can lift extremely large weights, show great numbers and develop impressive-looking muscles, but fail to lift a stone; they get completely hammered in a street fight by someone trained in more disorderly settings. Their strength is extremely domain-specific and their domain doesn't exist outside of ludic—extremely organized—constructs. In fact their strength, as with over-specialized athletes, is the result of a deformity. I thought it was the same with people who were selected for trying to get high grades in a small number of subjects rather than follow their curiosity: try taking them slightly away from what they studied and watch their decomposition, loss of confidence, and denial. (Just like corporate executives are selected for their ability to put up with the boredom of meetings, many of these people were selected for their ability to concentrate on boring material.) I've debated many economists who claim to specialize in risk and probability: when one takes them slightly outside their narrow focus, but within the discipline of probability, they fall apart, with the disconsolate face of a gym rat in front of a gangster hit man.

Steve Jobs: “People think focus means saying yes to the thing you’ve got to focus on. But that’s not what it means at all. It means saying no to the hundred other good ideas that there are. You have to pick carefully. I’m actually as proud of the things we haven’t done as the things I have done. Innovation is saying no to 1,000 things.

Further, my characterization of a loser is someone who, after making a mistake, doesn’t introspect, doesn’t exploit it, feels embarrassed and defensive rather than enriched with a new piece of information, and tries to explain why he made the mistake rather than moving on. These types often consider themselves the “victims” of some large plot, a bad boss, or bad weather. Finally, a thought. He who has never sinned is less reliable than he who has only sinned once. And someone who has made plenty of errors—though never the same error more than once—is more reliable than someone who has never made any.

Reality is far more vicious than Russian roulette. First, it delivers the fatal bullet rather infrequently, like a revolver that would have hundreds, even thousands of chambers instead of six. After a few dozen tries, one forgets about the existence of a bullet, under a numbing false sense of security. Second, unlike a well-defined precise game like Russian roulette, where the risks are visible to anyone capable of multiplying and dividing by six, one does not observe the barrel of reality. One is capable of unwittingly playing Russian roulette - and calling it by some alternative “low risk” game.

I suspect the I.Q., SAT, and school grades are tests designed by nerds so they can get high scores in order to call each other intelligent...Smart and wise people who score low on IQ tests, or patently intellectually defective ones, like the former U.S. president George W. Bush, who score high on them (130), are testing the test and not the reverse.

Consider a turkey that is fed every day. Every single feeding will firm up the bird’s belief that it is the general rule of life to be fed every day by friendly members of the human race “looking out for its best interests,” as a politician would say. On the afternoon of the Wednesday before Thanksgiving, something unexpected will happen to the turkey. It will incur a revision of belief.*

I don’t run for trains.” Snub your destiny. I have taught myself to resist running to keep on schedule. This may seem a very small piece of advice, but it registered. In refusing to run to catch trains, I have felt the true value of elegance and aesthetics in behavior, a sense of being in control of my time, my schedule, and my life. Missing a train is only painful if you run after it! Likewise, not matching the idea of success others expect from you is only painful if that’s what you are seeking. You stand above the rat race and the pecking order, not outside of it, if you do so by choice.

I am most often irritated by those who attack the bishop but somehow fall for the securities analyst--those who exercise their skepticism against religion but not against economists, social scientists, and phony statisticians. Using the confirmation bias, these people will tell you that religion was horrible for mankind by counting deaths from the Inquisition and various religious wars. But they will not show you how many people were killed by nationalism, social science, and political theory under Stalin or during the Vietnam War. Even priests don't go to bishops when they feel ill: their first stop is the doctor's. But we stop by the offices of many pseudoscientists and "experts" without alternative. We no longer believe in papal infallibility; we seem to believe in the infallibility of the Nobel, though....

The biologist and intellectual E. O. Wilson was once asked what represented the most hindrance to the development of children; his answer was the soccer mom. He did not use the notion of the Procrustean bed, but he outlined it perfectly. His argument is that they repress children's natural biophilia, their love of living things. But the problem is more general; soccer moms try to eliminate the trial and error, the antifragility, from children's lives, move them away from the ecological and transform them into nerds working on preexisting (soccer-mom-compatible) maps of reality. Good students, but nerds--that is, they are like computers except slower. Further, they are now totally untrained to handle ambiguity. As a child of civil war, I disbelieve in structured learning . . . . Provided we have the right type of rigor, we need randomness, mess, adventures, uncertainty, self-discovery, near-traumatic episodes, all those things that make life worth living, compared to the structured, fake, and ineffective life of an empty-suit CEO with a preset schedule and an alarm clock.
