Skin in the Game: Hidden Asymmetries in Daily Life (acronymed: SITG) is a 2018 nonfiction book by Nassim Nicholas Taleb, a former options trader with a background in the mathematics of probability and statistics. Taleb's thesis is that skin in the game—i.e., having a shared risk when taking a major decision—is necessary for fairness, commercial efficiency, and risk management, as well as being necessary to understand the world. The book is part of Taleb's multi-volume philosophical essay on uncertainty, titled the Incerto, which also includes Fooled by Randomness (2001), The Black Swan (2007–2010), The Bed of Procrustes (2010–2016), and Antifragile (2012). The book is dedicated to "two men of courage": Ron Paul, "a Roman among Greeks"; and Ralph Nader, "Greco-Phoenician saint". Source: Wikipedia (en)
