The event generally has a major effect or is shocking in nature. We’ll cover the meaning of “black swan,” what black swan theory is, and what “black swan” means in economics. This article is an excerpt from the Shortform summary of "The Black Swan" by Nassim Taleb. In Extremistan, however, randomness is wild, and deviations from the average can be, well, extreme. The term occurs as a countable noun and is also often used as a modifying adjective which usually appears in the expression black-swan event. What does “black swan” mean? Some key illustrations of the futility of prediction include: Most groundbreaking discoveries occur by happenstance—luck—rather than careful and painstaking work. It is a monogamous breeder, with both partners sharing incubation and cygnet-rearing duties. To explain how and why Black Swans occur and what “black swan” means, Taleb coins two categories to describe the measurable facets of existence: Extremistan and Mediocristan. Question 2: Why are scientific methods insufficient at predicting these rare events? The problem is that this model is innately narrow. The black swan theory provides two strategies for opening ourselves up to positive Black Swans: (1) sociability and (2) proactiveness when presented with an opportunity. New way to deal with risks and uncertainty. Voilá—the world’s first antibiotic. Most social, man-made aspects of human society—the economy, the stock market, politics—hail from Extremistan: They have no known upper or lower bounds, their behavior can’t be graphed on a bell curve, and individual events or phenomena—i.e., Black Swans—can have exponential impacts on averages. Once Taleb introduces the concept of the Black Swan, he delves into human society and psychology, analyzing why modern civilization invites wild randomness and why humans can neither accept nor control that randomness. Discoverer Alexander Fleming wasn’t researching antibiotics; rather, he was studying the properties of a particular bacterium. The “butterfly effect” describes the possibility that the flutter of a butterfly’s wings can, a few weeks later and many miles distant, cause a tornado. Although the most memorable Black Swans are typically the negatively disruptive ones, Black Swans can also be serendipitous. A dynamical system is one in which an array of inputs affect each other.

The history of the Black Swan theory. In Mediocristan, prediction is possible. This analyst may build a model using the gold standards of her field: past and current oil prices, car manufacturers’ projections, projected oil-field yields, and a host of other factors, computed using the techniques of regression analysis. Practice has shown that no one can ever predict crises (this is assumed by the theory itself), but experts all over the world regularly try to do […] Each … Taleb introduced the idea of Black Swan events as far back as 2001, but it grabbed attention when he dedicated an entire book on the subject in 2007 – just before the world suffered a Black Swan event in the form of the 2008 financial crash. A truly exciting, beautiful and mesmerising movie, it was directed by Darren Aronofsky and starring Natalie Portman, Vincent Cassel, Mila Kunis and Winona Ryder.

Because of various habits innate to our species—our penchant for telling stories, our belief in cause and effect, our tendency to “cluster” around specific ideas (confirmation bias) and “tunnel” into specific disciplines or methods (specialization)—we tend to miss or minimize randomness’s effect on our lives. Physical characteristics such as height and weight are from Mediocristan: They have upper and lower bounds, their distribution is a bell curve, and even the tallest or lightest human being isn’t much taller or lighter than the average. The Black swan theory, postulated by Nassim Nicholas Taleb, is used to describe the impact of events that come as a surprise in societal aspects.

Answer 1: They occur with low frequency, hence these events are not treated with high regard in realms where hypotheses are proven by highly frequent observations. According to black swan theory, there are two reasons “experts” make bad predictions: Because of various habits innate to our species—our penchant for telling stories, our belief in cause and effect, our tendency to “cluster” around specific ideas (confirmation bias) and “tunnel” into specific disciplines or methods (specialization)—we tend to miss or minimize randomness’s effect on our lives. Taleb outlined the three defining attributes of a black swan event: 1. The barbell strategy is an important part of Taleb’s black swan theory. In financial modeling, this process is typically used to estimate changes in the value of a business or cash flow.

The past itself is as unknowable as the future, even the major black swan events. The theory of Black Swan events was developed to categorize non-predictable, high-impact events. Experts like biologists and astrophysicists are able to predict events with fair accuracy; experts like economists and financial planners are not. The Black swan theory, postulated by Nassim Nicholas Taleb, is used to describe the impact of events that come as a surprise in societal aspects.The event is unprecedented at a particular point in time until it happens.

He left a stack of cultures lying out in his laboratory while he went on vacation, and when he returned he found that a bacteria-killing mold had formed on one of the cultures. Whereas prediction in a system that contains, say, two inputs, is a simple affair—one need only account for the qualities and behavior of those two inputs—prediction in a system that contains, say, five hundred billion inputs is effectively impossible. Your email address will not be published. According to Taleb, a Black Swan event has three attributes: The most famous illustration of a dynamical system’s properties is the “butterfly effect.” This idea was proposed by an MIT meteorologist, who discovered that an infinitesimal change in input parameters can drastically change weather models.
