The essayist Nassim Taleb, who made his name with the wider public with his 2007 book The Black Swan (a book with some very powerful insights but a miserable prose style), has long had a fascination with uncertainty and events that fall at the far ends of statistical distributions. He’s also a firm believer in only being guided by those who have ‘skin in the game’ – this catchphrase also being the title of his most recent 2018 book.
