They will penalize outsiders, seemingly gratuitously. They will sacrifice, and even kill and die, for their group.
This may seem like common sense. And yet the power of tribalism rarely factors into high-level discussions of politics and international affairs, especially in the United States. In seeking to explain global politics, U.S. analysts and policymakers usually focus on the role of ideology and economics and tend to see nation-states as the most important units of organization. In doing so, they underestimate the role that group identification plays in shaping human behavior. They also overlook the fact that, in many places, the identities that matter most—the ones people will lay down their lives for—are not national but ethnic, regional, religious, sectarian, or clan-based. A recurring failure to grasp this truth has contributed to some of the worst debacles of U.S. foreign policy in the past 50 years: most obviously in Afghanistan and Iraq, but also in Vietnam.
