Review
Heroes and Cowards is interesting to read. . . . It is a work of military sociology written with one eye on the debate about the social costs of diversity. . . . Ms. Costa and Mr. Kahn emphasize the advantages of trust and mutual sacrifice that come from social similarity. They understand full well the contemporary implications of their historical study. When we contemplate helping others, whether through volunteer organizations or welfare--state transfers, we are less likely to provide for--and more likely to abandon--those who are unlike ourselves.

In their new book
Heroes and Cowards, economists Dora Costa and Matthew Kahn use the Civil War as their laboratory to study what men will do in the name of friendship. They find that men serving in companies with tight social connections--like shared birthplace and occupation--were more likely to stand and fight than those in less tight-knit companies, where desertion rates were up to four times higher.

Review
This impressive study, based on a random sample of forty thousand Civil War soldiers both black and white, reaches important conclusions about their motivation and behavior. Its most significant findings emphasize the role of close social networks within companies and regiments in promoting combat performance, preventing desertion, and increasing survival rates in POW camps. Readable and accessible to nonspecialists, this book should find a wide audience among those interested in the Civil War as well as group behavior more generally.
