In the absence of explicit punitive sanctions, why do individuals voluntarily participate in intergroup warfare when doing so incurs a mortality risk? Here we consider the motivation of individuals for participating in warfare. We hypothesize that in addition to other considerations, individuals are incentivized by the possibility of rewards. We test a prediction of this “cultural rewards war-risk hypothesis” with ethnographic literature on warfare in small-scale societies. We find that a greater number of benefits from warfare is associated with a (...) higher rate of death from conflict. This provides preliminary support for the relationship between rewards and participation in warfare. (shrink)

With armed conflict in the Persian Gulf now upon us, Harvard archaeologist Steven LeBlanc takes a long-term view of the nature and roots of war, presenting a controversial thesis: The notion of the "noble savage" living in peace with one another and in harmony with nature is a fantasy. In Constant Battles: The Myth of the Peaceful, Noble Savage , LeBlanc contends that warfare and violent conflict have existed throughout human history, and that humans have never lived in ecological balance (...) with nature. The start of the second major U.S. military action in the Persian Gulf, combined with regular headlines about spiraling environmental destruction, would tempt anyone to conclude that humankind is fast approaching a catastrophic end. But as LeBlanc brilliantly argues, the archaeological record shows that the warfare and ecological destruction we find today fit into patterns of human behavior that have gone on for millions of years. Constant Battles surveys human history in terms of social organization-from hunter gatherers, to tribal agriculturalists, to more complex societies. LeBlanc takes the reader on his own digs around the world -- from New Guinea to the Southwestern U.S. to Turkey -- to show how he has come to discover warfare everywhere at every time. His own fieldwork combined with his archaeological, ethnographic, and historical research, presents a riveting account of how, throughout human history, people always have outgrown the carrying capacity of their environment, which has led to war. Ultimately, though, LeBlanc's point of view is reassuring and optimistic. As he explains the roots of warfare in human history, he also demonstrates that warfare today has far less impact than it did in the past. He also argues that, as awareness of these patterns and the advantages of modern technology increase, so does our ability to avoid war in the future. (shrink)
