The black Swan

The Black Swan: The Impact of the Highly Improbable is a 2007 book by author and former options trader Nassim Nicholas Taleb. The book focuses on the extreme impact of rare and unpredictable outlier events—and the human tendency to find simplistic explanations for these events, retrospectively. Taleb calls this the Black Swan theory. The book covers subjects relating to knowledge, aesthetics, as well as ways of life, and uses elements of fiction and anecdotes from the author's life to elaborate his theories. It spent 36 weeks on the New York Times best-seller list.The book is part of Taleb's five volume series, titled the Incerto including Fooled by Randomness (2001), The Black Swan (2007–2010), The Bed of Procrustes (2010–2016), Antifragile (2012), and Skin in the Game (2018).
