  1. There is a positive association between male aggression and societies with polygyny and a high variance in the number of wives.Carter, Tara-Lyn - Male aggressiveness as intrasexual contest competition in a cross-cultural s..., 2018 - 7 Variables

    The present study tests the theory that intrasexual selection or male attraction may explain variation in male aggression in a sample of 78 societies. Measures of intrasexual selection include: male subsistence, male war mortality, polygyny, sex ratio, and wives variance. The authors claim support for the theory.

  2. Aggression is lower in societies where males show greater subsistence effort.Carter, Tara-Lyn - Male aggressiveness as intrasexual contest competition in a cross-cultural s..., 2018 - 5 Variables

    The present study tests the theory that intrasexual selection or male attraction may explain variation in male aggression in a sample of 78 societies. Measures of intrasexual selection include: male subsistence, male war mortality, polygyny, sex ratio, and wives variance. The authors claim support for the theory.

  3. "There is no significant association between a long postpartum taboo and polygyny in either the high or low male mortality situation . . . when we control for male mortality in warfare" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 3 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

  4. "[Societies] with a high male loss in warfare are significantly more likely to have an imbalanced sex ratio in favor of females than . . . [societies] with a low or zero male loss in warfare" (201-202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 2 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

  5. "In the presence of a short [postpartum sex] taboo, which is the more crucial control situation, . . . [there is a strong] correlation between high male mortality and polygyny" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 3 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

  6. "However, when we control on Whiting's predictor, i.e., presence or absence of a long postpartum sex taboo, a strong relationship between high male mortality and polygyny still obtains, in the presence of both a long and a short postpartum sex taboo" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 3 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

  7. "A high male mortality in warfare is strongly associated with polygyny" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 2 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

  8. Warfare of all types (external, internal and overall) will be negatively related to proportion of noncombative sports and positively related to proportion of individual combative sports, team combative sports, and sham combats.Chick, Garry - Combative sport and warfare: a reappraisal of the spillover and catharsis hy..., 1997 - 4 Variables

    A replication of Sipes' (1973) study of the relationship between combative sport and warfare using new codes and a new sample. Although many of the results are weaker than found by Sipes previously, they are still consistent with the culture pattern model as compared with the drive-discharge model.

  9. "Frequent external warfare should be correlated with a higher degree of male exogamy than when external warfare is infrequent" (304)Divale, William Tulio - The causes of matrilocal residence: a cross-ethnohistorical survey, 1974 - 2 Variables

    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.

  10. Frequency of warfare will be negatively associated with a high male-to-female sex ratio. (2)Stone, Emily A. - A Test of an Evolutionary Hypothesis of Violence against Women: The Case of ..., 2017 - 2 Variables

    This paper presents empirical tests of two theories put forth to explain violence toward women. The first predicts that warfare promotes socialization for aggression and legitimizes violence toward women, while the second predicts that violence works as a way to control potential for female infidelity. An association is found between high male-to-female sex ratio and violence towards women, suggesting support for the second theory over the first, which is consistent with more narrowly-focused studies by Avakame (1999), Bose et al. (2013), and D'Alessio & Stolzenberg (2010).
