Power and the Evolution of Inequity
The chapter starts with an introduction of the primary paradigm used in this half of the book—the bargaining game. It uses this model to show why in groups with social categories fairness in bargaining is not the expected outcome of cultural evolution. Instead, social categories act as a symmetry breaker that stabilizes inequitable bargaining conventions. The chapter then turns to the role power plays in the evolution of bargaining. Powerful groups often gain an advantage with respect to the emergence of conventions of resource division. This can lead to compounding processes that profoundly disadvantage some social groups. These models make especially clear how irrelevant markers like race and gender can come to be more important in determining resource division than relevant factors, such as individual status.
