The Bounds of Reason

Gintis contributes importantly to a new insight gaining ascendancy: economy is about the unintended consequences of human sociality. This book is firmly in the revolutionary tradition of David Hume (Convention) and Adam Smith (Sympathy). -- Vernon L. Smith, Nobel Prize-winning economist Herbert Gintis makes a strong case that game theory--by predicting social norms--provides an essential tool for understanding human social behavior. More provocatively, Gintis suggests that humans have a genetic tendency to follow social norms even when it is to their disadvantage. These claims will be controversial--but they make for fascinating reading. -- Eric S. Maskin, Nobel Laureate in Economics Recent findings in experimental economics have highlighted the need for a rigorous analytical theory of choice and strategic interaction for the social sciences that captures the unexpectedly wide variety of observed behaviors. In this exciting book, Gintis convincingly argues that an empirically informed game-theoretic approach goes a long way toward achieving this attractive goal. -- Ernst Fehr, University of Zurich This brave and sweeping book deserves to be widely and carefully read. -- Adam Brandenburger, New York University The Bounds of Reason makes a compelling case for game theory but at the same time warns readers that there is life beyond game theory and that all social science cannot be understood by this method alone. This splendid book makes skillful use of figures and algebra, and reads like a charm. -- Kaushik Basu, Cornell University Excellent and stimulating, The Bounds of Reason is broad enough to encompass the central concepts and results in game theory, but discerning enough to omit peripheral developments. The book illustrates deep theoretical results using simple and entertaining examples, makes extensive use of agent-based models and simulation methods, and discusses thorny methodological issues with unusual clarity. -- Rajiv Sethi, Barnard College, Columbia University

Game theory is central to understanding human behavior and relevant to all of the behavioral sciences - from biology and economics, to anthropology and political science. This title demonstrates that game theory alone cannot fully explain human behavior and should instead complement other key concepts championed by the behavioral disciplines.Game theory is central to understanding human behavior and relevant to all of the behavioral sciences--from biology and economics, to anthropology and political science. However, as The Bounds of Reason demonstrates, game theory alone cannot fully explain human behavior and should instead complement other key concepts championed by the behavioral disciplines. Herbert Gintis shows that just as game theory without broader social theory is merely technical bravado, so social theory without game theory is a handicapped enterprise. Gintis illustrates, for instance, that game theory lacks explanations for when and how rational agents share beliefs. Rather than construct a social epistemology or reasoning process that reflects the real world, game theorists make unwarranted assumptions which imply that rational agents enjoy a commonality of beliefs. But, Gintis explains, humans possess unique forms of knowledge and understanding that move us beyond being merely rational creatures to being social creatures. For a better understanding of human behavior, Gintis champions a unified approach and in doing so shows that the dividing lines between the behavioral disciplines make no scientific sense. He asks, for example, why four separate fields--economics, sociology, anthropology, and social psychology--study social behavior and organization, yet their basic assumptions are wildly at variance. The author argues that we currently have the analytical tools to render the behavioral disciplines mutually coherent. Combining the strengths of the classical, evolutionary, and behavioral fields, The Bounds of Reason reinvigorates the useful tools of game theory and offers innovative thinking for the behavioral sciences.
