One of the key scientific challenges is the puzzle of human cooperation. Why do people help strangers, even sometimes at a major cost to themselves? Why do people want to punish others who violate norms and undermine collective interests? What are the emotions that accompany reward and punishment? Even if reward and punishment are effective, are they also efficient - knowing that rewards and punishment are costly to administer? In this book, the first in a series on human cooperation, authors explore the workings of reward and punishment, how they should be organized, and their functions in society, thereby providing a synthesis of the psychology, economics, and neuroscience of human cooperation.
