'Alan Fiske is among the grandest scholars in the social sciences and this book is the magnificent summation of his life's work. He shows you the four basic models of human relationships that are the keys to understanding how people work together to create almost everything: families, friendships, teams, companies, governments … and misunderstandings. This book will give you something akin to X-ray vision into social life, institutions, customs, and the drama of human affairs.' Jonathan Haidt, Thomas Cooley Professor of Ethical Leadership, New York University, USA, and author of The Anxious Generation
