I'm interested in the scaling up of society and the evolution of political decision-making, norms, and institutions. We currently lack a robust theory of institutions or institutional selection, though institutions are often called upon for explaining phenomena. Understanding institutions requires understanding them as both group level phenomena and products of individual decision-making. I believe that behavior is a function of how individuals perceive the world around them. To integrate these approaches, I call on theory and methods from cultural evolutionary theory and cognitive anthropology and use economic, psychological, cognitive, and affective experiments. Additional interests are folksociology (how people think about groups, society, etc.) and collective action. I consider myself to be both an anthropologist and a more general behavioral scientist.
