Abstract“Culture of honor” means that individuals deter others by signaling their commitment to violent retaliation. We develop a multilevel explanation of cross-level interdependence of honor and violence. According to our concept of system-level honor, a social system is loaded with deterrence signaling if culture of honor is highly prevalent in the system. In line with the Smith and Price (1973, in Nature,https://www.nature.com/articles/246015a0) model, we argue that high system-level honor discourages Prober-Retaliator behavior: some individuals might tend to challenge others they assume (...) to be inferior to increase their own reputation. Both individual culture of honor and system-level honor contribute to an increase in violence (H1; H2). However, as system-level honor and deterrence become more prevalent, the impact of individual honor diminishes because engaging in violent behavior becomes increasingly expensive within such a system (H3). As a second contextual effect, inequality in culture of honor should therefore increase violent behavior because it encourages Prober-Retaliator behavior (H4). We analyze the effect of culture of honor on school violence among 15-year-old adolescents. Disentangling the micro- and context-level effects of culture of honor on violent behavior in a multilevel analysis framework allows the estimation of a cross-level interaction using a large data set from more than 25,000 adolescents in more than 1,300 schoolroom contexts. Results are in line with our H3, but not with H4. Model-based predictions show that the deterrent effect must be unrealistically high to generate an equilibrium of average violence. (shrink)

This special issue of Human Nature presents selected works from the 2015 and 2017 “Warfare, Environment, Social Inequality, and Pro-Sociability” conferences held at the Center for Cross-Cultural Study in Seville, Spain. These investigations explore the manifestations of indigenous warfare and violence from a host of theoretical perspectives. Topics range from the origins of warfare to the psychological repercussions of combat, the relationship between warfare and status, as well as the documentation of peace processes among warring groups. This issue also examines (...) the effects of militarization and coercive conservation on indigenous peoples. (shrink)
