at New York University Tandon School of Engineering since 2008. He was Distinguished Research Scholar at the Said Business School BT Center, University of Oxford from 2009 to 2013. Taleb is co-Editor in Chief of the academic journal Risk and Decision Analysis (since September 2014), jointly teaches regular courses with Paul Wilmott in London (19th time, March 2015), and occasionally participates in teaching courses toward the Certificate in Quantitative Finance. He is also co-faculty at the New England Complex Systems Institute. In late 2015, Taleb, Robert J. Frey and Raphael Douady formed the Real World Risk Institute "to build the principles and methodology for what we call real-world rigor, in decision making and codify a clear-cut way to approach ... to provide executive education courses and issue two certificates." Writing career Taleb's five volume philosophical essay on uncertainty, titled Incerto, covers the following books: Fooled by Randomness (2001), The Black Swan (2007–2010), The Bed of Procrustes (2010), Antifragile (2012), and Skin in the Game (2018). It was originally published in November 2016 including only the first four books. The fifth book was added in August 2019. His first non-technical book, Fooled by Randomness, about the underestimation of the role of randomness in life, published in 2001, was selected by Fortune as one of the smartest 75 books known. His second non-technical book, The Black Swan, about unpredictable events, was published in 2007, selling close to three million copies (as of February 2011). It spent 36 weeks on the New York Times Bestseller list, 17 as hardcover and 19 weeks as paperback, and was translated into 31 languages. The book has been credited with predicting the banking and economic crisis of 2008. A book of aphorisms, The Bed of Procrustes: Philosophical and Practical Aphorisms, was released in December 2010. The fourth book of his Incerto series—Antifragile: Things That Gain from Disorder—was published in November 2012. The fifth book of his Incerto series—Skin in the Game: Hidden Asymmetries in Daily Life—was published in February 2018. Taleb's non-technical writing style has been described as mixing a narrative, often semi-autobiographical style with short philosophical tales and historical and scientific commentary. The sales of Taleb's first two books garnered an advance of $4 million, for a follow-up book on anti-fragility.
