HowardRheingold asks whether science can reach a deep understanding of this question [1]. He writes: "The entire puzzle of how groups of different sizes agree to cooperate, why and how cooperation breaks down, how conflicts arise, intensify, and resolve, is largely unknown. But the puzzle pieces from a dozen different disciplines are beginning to fit together to reveal larger patterns. Part of the current lack of understanding may stem from the nature of specialized scientific inquiry: biologists, economists, psychologists, sociologists, anthropologists, computer scientists, game theorists, and political scientists have only recently begun to suspect that they hold parts of the same puzzle.It has taken some time for those studying cooperation, reputation, and conflict to recognize the need for interdisciplinary syntheses."
