My research focuses on political leadership and understanding strategies of leadership and followership in small-scale societies. I use comparative methods and behavioral-observational research to evaluate established theoretical models with systematic data from small-scale societies. My Master's thesis tested three evolutionary theoretical models of leadership cross-culturally in the ethnographic record.
In my cross-cultural research, I am currently working on assessing the qualities and functions of leaders and the costs and benefits of leadership for both leaders and followers across distinct domains of social behavior. For example, how do the traits of military leaders compare to work-group or spiritual leaders across traditional societies? And, what types of leaders are receiving the most substantial reproductive, social, or economic benefits relative to followers? The next phase of my comparative ethnographic research seeks to answer such questions.
I conduct fieldwork in the Sheka forest of Southwest Ethiopia with the Chabu forager-horticulturalists and am investigating the utility of the dominance-prestige model, and others, in understanding formal leadership positions and sex-differences in leadership. The Ethiopian government has implemented the Kebele system of neighborhood administration among the Chabu, which involves electing individuals for specific leadership roles. My Ph.D. research investigates the nature of this hierarchical leadership system in the context of an egalitarian social structure.
Future field research with the Chabu will more specifically investigate the ontogeny of leadership, leadership in large-scale collective activities, the role of charisma in religious leadership, the function of leadership in musical performance, and the role of perceived supernatural abilities and expertise in clan-based prestige.
