Herding,Warfare, and a Culture of Honor: Global Evidence* Yiming Cao† Benjamin Enke‡ Armin Falk§ Paola Giuliano¶ Nathan Nunn|| 7 September 2021 Abstract: According to the widely known ‘culture of honor’ hypothesis from social psychology, traditional herding practices have generated a value system conducive to revenge-taking and violence. We test the economic significance of this idea at a global scale using a combination of ethnographic and folklore data, global information on conflicts, and multinational surveys. We find that the descendants of herders have significantly more frequent and severe conflict today, and report being more willing to take revenge in global surveys. We conclude that herding practices generated a functional psychology that plays a role in shaping conflict across the globe. Keywords: Culture of honor, conflict, punishment, revenge. *We thank Anke Becker, Dov Cohen, Pauline Grosjean, Joseph Henrich, Stelios Michalopoulos and Thomas Talhelm for useful discussions and/or comments on the paper. †Boston University.

Introduction A culture of honor is a bundle of values, beliefs, and preferences that induce people to protect their reputation by answering threats and unkind behavior with revenge and violence. According to a widely known hypothesis, that was most fully developed by Nisbett( 1993) and Nisbett and Cohen( 1996), a culture of honor is believed to reflect an economically-functional cultural adaptation that arose in populations that depended heavily on animal herding (pastoralism).1 The argument is that, relative to farmers, herders are more vulnerable to exploitation and theft because their livestock is a valuable and mobile asset.
