The article investigates whether more socially restrictive societies provide more outlets for aggression. These authors operationalized restrictiveness with the presence of sorcery and unilineal kinship structure; the two outlets for aggression examined were occurrence of warfare and games of physical skill. Results suggest an association between these variables, though unilineal kinship structure was the better predictor of the existence of warfare.
