This paper offers a tentative theory of avunculocal residence: societies that were matrilocal and matrilineal will be likely to develop avunculocality when they switch to internal warfare and experience a high male mortality rate. Some cross-cultural evidence to support this theory is provided.

This article explores narcissism and child-rearing. The author presents a theory that, if a society’s structural pattern weakens the marital bond, the mother will be ambivalent toward the son who consequently will become narcissistic. This process would reinforce itself as it is repeated by each generation.

The article tests theories that may explain why warfare frequency varies from society to society. The focus is on ecological problems, particularly different kinds of resource scarcity, but social and psychological theories are also tested with both bivariate and multivariate analyses. Because unpredictable disasters are such a strong predictor in nonstate societies, the authors theorize that war may mostly be caused by a fear of nature.
