This article considers the consequences of modernization. Factor analysis is used to identify four stages of modernization: 1) changes in education, government, and trade; 2) changes in health, technology, and transportation; 3) changes in family, religion, and toilet; and 4) changes in behavior. The authors then consider five trends they expect to be associated with modernization and test whether they develop over the course of the four stages. Results indicate that these 5 trends—increased cultural complexity, female status, pacification, suicide, and social stress—are associated with only the first and fourth stages.

This study examines two theories concerning the prevalence of rape: deterrence theory and fraternal interest group theory. Results indicate that both punishment and fraternal interest groups influence the frequency of rape, though neither variable is a necessary cause. The effects of marital residence and polygyny are also considered.

This study examines the influence of the "child-adult" conflict on the frequency of drunkenness in a culture. In particular, the author examines the socio-psychological factors that can induce a child-adult conflict, claiming that this conflict may be more common when mothers are the primary dispensers of rewards.

Author proposes and presents evidence in support of the theory that most societies practice virilocal or patrilocal residence (this is the "normal" pattern" and that matrilocal residence is adopted when societies migrate to an already populated area.

The author analyzes 76 societies synchronically, positing that the evil eye belief functions as a useful heuristic and prosocial/cohesive element in weakly-institutionalized societies with significant wealth inequality; in particular, the evil eye belief is found to be more prevalent in agro-pastoral societies where material wealth is vulnerable and plays a dominant role in subsistence economy.

This article investigates variables related to suicide in preindustrial societies. Bivariate analyses indicate associations between rates of suicide and religion, kinship, political and economic integration, expression of emotions, and importance of pride. Multiple regression identifies three key predictors of suicide: the major economic activity, rules concerning the expression of emotions, and the importance of pride and shame.

Using a sample of 80 countries and political regions, the present study examines the effect parasite stress has on people's trust towards ingroup and outgroup members. The findings do not offer support of there being a concave relationship between parasite stress and ingroup member trust. The results do indicate that there is a U-correlation between trusting outgroup members and parasite stress.
