This paper investigates the emotional and social outcomes of water sharing within societies and suggests water sharing is a unique reciprocity act that results in negative emotional outcomes, rather than the usual prestige and rank. A questionnaire regarding water sharing and receiving was carried out across 20 sites, targeting 250 houses per community. The authors found that both water sharing and receiving resulted in more distress and conflict than those who shared less.

This article tests several hypotheses related to the presence or absence of polygyny. Results suggest a negative relationship between polygyny and male provisioning, and positive relationships between polygyny and warfare, interpersonal aggression, and pathogen stress.

This paper investigates five different economic types of foragers: classic, transitional system, politically oriented, economically oriented, and intangibles-oriented. The author asserts that these economic types “are not mere epiphenomena of the oft-discussed social structural or political forces but, rather, are special characteristics that must be independently taken into account” (418). A myriad of environmental, subsistence, political, and social variables are examined: some differed significantly across the five economic types of foragers, but others such as famine threat, conflict, locational fixity, marital form, and postmarital residence did not differ between types.

This study examines some of the environmental and psychological predictors of warfare frequency and interpersonal aggression. Results suggest that socialization for aggression in boys is the most significant predictor of warfare. However, authors suggest that socialization for aggression may be a consequence, rather than a cause, of war.
