Local socialization, not inherent nature, shapes whether groups become warrior or peaceful peoples

Evidence

That divergent cultural practices produce different human natures is further shown in contrasting lifestyles of people coexisting for centuries in different regions of the same nation. Dissimilar socialization practices produced markedly different characteristics in different Native American peoples. The Apache and Comanche peoples raised their children to be valiant warriors (Goodwin, 1942; Linton, 1945), whereas the Hopi and the Zuni, who embraced peaceful lifestyles, reared children with gentle dispositions (Goldfrank, 1945). — Albert Bandura, Moral Disengagement, 173
