What You Do Is Who You Are

Horowitz's central move is to argue that culture is what people actually do under pressure, not a values poster in the break room, and he illustrates this through four case studies: Toussaint Louverture's Haitian revolt, samurai bushido, Genghis Khan's meritocratic army, and Shaka Senghor's transformation of a prison gang. It's a clever structural gambit for a business book, but it's also the book's most argued-over feature: critics have pushed back hard on stretching Louverture's fight against slavery into a lesson about corporate frugality, calling the analogy strained and tone-deaf to the historical stakes involved. The Nas and Bill Campbell anecdotes land better than the empire-building ones. Read it for the operating principles on shocking rules and hiring for culture fit, and read the historical chapters with some skepticism.
