Introduction

Cooperation is ubiquitous in the natural world. But the expansion of human prosociality beyond the small-scale bands that characterised the majority of human evolutionary history to large-scale societies of unrelated individuals is unusual and requires explanation. Reputation and supernatural beliefs are two possible mechanisms for this. Reputation is a unique human feature that is thought to be crucial in underpinning cooperative systems. Supernatural and religious beliefs are widely distributed among human societies, although their role in the evolution of human prosociality remains under debate. My project tests hypotheses relating to the role of reputation and supernatural beliefs as mechanisms for cooperation. It uses cultural phylogenetics and other quantitative methods to analyse reputational punishment, in the form of witchcraft accusations, among Bantu tribes in Africa. It investigates the evolution and ecology of such beliefs. I have also undertaken fieldwork in Northern Ireland, using economic games to examine how reputation, religious belief and cooperation interact.
