Taleb asserts that by adopting these strategies a portfolio can be "robust", that is, gain a positive exposure to black swan events while limiting losses suffered by such random events. Jaynes that economic life increases in entropy under regulatory and other constraints. Instead of doing steady and moderate exercise daily, he suggests that it is better to do a low-effort exercise such as walking slowly most of the time, while occasionally expending extreme effort. He claims that the human body evolved to live in a random environment, with various unexpected but intense efforts and much rest.

In other words, studies that ignore the random nature of supply of nutrients are invalid. Praise and criticism[ edit ] In a article in The Times , the journalist Bryan Appleyard described Taleb as "now the hottest thinker in the world".

His book, The Black Swan, is an original and audacious analysis of the ways in which humans try to make sense of unexpected events. The magazine offered a mixture of praise and criticism for Taleb's main points, with a focus on Taleb's writing style and his representation of the statistical literature.

Robert Lund, a mathematics professor at Clemson University , writes that in Black Swan, Taleb is "reckless at times and subject to grandiose overstatements; the professional statistician will find the book ubiquitously naive.

His writing is full of irrelevances, asides and colloquialisms, reading like the conversation of a raconteur rather than a tightly argued thesis. But it is hugely enjoyable — compelling but easy to dip into.

Yet beneath his rage and mockery are serious issues. The risk management models in use today exclude the very events against which they claim to protect the businesses that employ them. These models import a veneer of technical sophistication Quantitative analysts have lulled corporate executives and regulators into an illusory sense of security.

Taleb said that Scholes was responsible for the financial crises of , and suggested that "this guy should be in a retirement home doing Sudoku. His funds have blown up twice.

The Black Swan Summary

I was told to focus and I never did. I was told to never procrastinate and I waited 20 years for The Black Swan and it sold 3 million copies. I was told to avoid putting fictional characters in my books and I did put in Nero Tulip and Fat Tony because I got bored otherwise. I was told to not insult the New York Times and the Wall Street Journal, the more I insulted them the nicer they were to me and solicit op-eds.

I was told to avoid lifting weights for a back pain and became a weightlifter: never had a back problem since. If I had to relive my life I would be even more stubborn and uncompromising than I have been. One should never do anything without skin in the game. If you give advice, you need to be exposed to losses from it. Random events, along with our cognition failures, create logical challenges that, if we do not understand how our brain works and how we deal with them, can bring us major problems.

What is a Black Swan? Is it something positive, or a mere reflection of the bad things that occur? Do you ask yourself these questions as you are reading this? Written and designed for all audiences especially for enthusiasts that are restless and hungry for new knowledge that opposes the traditional way of predicting, forecasting, analyzing, calculating and estimating different events that happened or may happen in the future.

Nassim Nicholas Taleb was born in in Amioun, Lebanon. He is an American-Lebanese essayist, philosopher researcher, trader, and financier who works and dwells in the US. As a polyglot Taleb fluently speaks five languages: You know that you should read the book and you know who the author is.

To understand Black Swan, first, you must comprehend certain critics and opinions by philosophers, experts, and writers in different fields. Thinking is a relative concept that is based on uncertainty and possibilities. Now we get to define the term.

Black swans are labeled as an unfortunate turn of events, which are not only explainable but understandable as well.

Anyway, you have to show flexibility and open-mindset to accept such dose of uncertainty without falling into despair. Over the course of thousands of years, the symbolic meaning of Black Swans has swept the world. It changes history, literature, business climate, science, economy and everything the sun touches. Connecting with each other is becoming a straightforward mechanism, now more than ever.

The Bell Curve is one of the few statistical-forecasting factors, which turn a blind eye to the effects deriving from black swans.

These tools are casting doubt on randomness, and refuse to acknowledge its realistic waves. They also provide future predictions and precise explanations as worst as possible. Even a movie starring Natalie Portman is set to give you a hint on the future while recalling memories and memorable events. It was not possible to predict that the Black Swan existed before it was first seen. Rare events like the first Black Swan occur more often than we imagine and our minds are programmed to deal with what we have seen before.

However, extreme events usually occur and have significant impacts. Our tendency to ignore them comes from the fact that people tend to underestimate their ignorance. There is much that we do not know, but since feeling ignorant is something that does not make us feel good about ourselves, we tend to downplay this characteristic of ours. We create stories where they do not exist. Human knowledge is constantly growing and evolving, and the dogmatic approach we tend to take makes no sense.

We cannot be sure of our beliefs, for they make us blind to concepts that are outside what we believe to be true. Black swans are the events that cause vast cognitive transformations, whether minor or enormous, such as the destruction of a sector in the stock market or a political crisis. The only way to be aware of these impacts is information.

The more ignorant you are, the more likely you are to be surprised by a swan. The more informed you are, the less likely you will be hit. A Black Swan can transform the whole modern understanding of science, impacting philosophy, theology, and physics. In the 15th century, when Nicolaus Copernicus proposed that the earth was not the center of the universe, the consequences were immense, at all levels.

He challenged religion yes, the Catholic church suffered major impacts , but also paved the way for a cultural change in society and science. To better understand the impact of the unlikely, Nassim Taleb divides human knowledge into two main areas of randomness, separating the two major groups of unlikely effects in our lives. By dividing the improbable into two large groups, it becomes easier to understand how it deceives us and thus proves our inability to make predictions.

The first of them is called by Taleb of Mediochristian, describing a land where averages are the rule. In Mediochristian our sampling of information and data available is very large, and no single fact will change the way the model works. The data in this context is not scalable, as it has defined a minimum and a maximum limit. Examples of Mediochristian information are, for example, physical characteristics such as height and body weight, and even IQ. Since the properties of such non-scalable information are certainly limited, it is possible to make relatively accurate predictions about the means.

In Extremistan, the information is so disproportionate that a single observation can dramatically impact our observations and mislead our ability to make predictions.

Examples of data and information emerging from the Far East are far more diverse. Examples include: Deaths in terrorist attacks, book sales by an author, inflation rates. Other than data such as height and weight, wealth distribution and album sales are scalable items. For example, you can sell your book in digital format through Kindle infinitely, because the digital format does not require you to print a book with each copy sold.

Another example is wealth, which is highly scalable: And if you analyze the data looking at the average, you can be deceived with a representation of the income distribution that does not accurately reflect the reality of people. Be careful not to be turkey on Thanksgiving Day… Imagine the following scenario.

You are a turkey, which is fed daily, well taken care of every day, for years and your life is going ok. But on Thanksgiving, a surprise occurs.

You are not fed, you are murdered and eaten by the people who feed you. That is the metaphor that Taleb uses to illustrate how to observe the past to predict the future. It also proves that the Black Swans are relative.

For you the turkey , the Thanksgiving dinner is definitely a Black Swan, but for the Thanksgiving dinner cook, there is no surprise in this event. We often look at our lives as if things were happening in the Mediochristian, when, in fact, life occurs much more in the kingdom of Extremistan. To learn to deal with this, one must accept, embrace and understand the unpredictable nature of the world, rather than ignore it.

That will not make you not be the turkey, but at least it will allow you not to get accustomed to the status quo. Our brains play tricks on us. We tend to conclude that similar sounding phrases have absurdly different meanings. The lack of proof that something exists does not mean that it does not exist.

It is not because there has never been an earthquake in your city, that it will never occur, will it?

But given our ignorance, to seek evidence that what we believe is real can greatly limit our line of thought and make us ignore information that does not support our beliefs. It is often more valuable to search for facts that go against our beliefs than those which support it.

That leads to much more powerful discoveries and allows us not to be blinded. Another flaw in our operating system is that we are in the habit of creating stories based on collections of events that occur in our lives. The author calls this failure a narrative fallacy. It is characterized by exploiting our limited ability to analyze sequences of events without adding an explanation to them.

Explanations tie the facts and make them easier to remember, but our brains always seek to tell a story where events are correlated and meaningful. However, by condensing facts into a single narrative, we end up generating a loss of information and have a great tendency to oversimplify things. We discard the data that makes no sense in our history, and that leaves us at the mercy of the swans.

According to cognitive psychologists, we have two kinds of thoughts. Type 1 thinking is instinctive, fast, immediate, and based on your experience with the world. This system is advantageous for having high speed and helps you react quickly to external stimuli but is also very prone to errors.
