  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.

  3. Social complexity will be positively associated with frequency of warfare (8).Ember, Melvin - Fear of disasters as an engine of history: resource crises, warfare, and int..., 1988 - 2 Variables

    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.

  5. Internal warfare will predict the percent of married men who are polygynous.Minocher, Riana - Explaining marriage patterns in a globally representative sample through soc..., 2019 - 2 Variables

    Researchers examine marriage patterns of 186 societies from the Standard Cross-Cultural Sample (SCCS). The eleven predictor variables are pathogen stress, arranged female marriages, population density, father roles during infancy, temperature, social stratification, wealth inequality, internal warfare, assault frequency, female agricultural contribution, and sex ratio. The two outcome variables measuring polygyny are cultural rules constraining polygyny and the percentage of married men who are polygynous. Controlling on phylogeny using a global supertree of the languages, analysis of marriage patterns reveals that assault frequency and pathogen stress are the strongest predictors of polygyny. These findings offer additional support for the theories of harem-defense polygyny and male genetic quality.

  7. Foragers will have less warfare than societies with other subsistence strategies (6).Ember, Carol R. - Violence in the ethnographic record: results of cross-cultural research on w..., 1997 - 2 Variables

    This paper reviews the results of the author's cross-cultural studies of war and aggression and their implications for prehistory.

  8. In a subsample excluding societies that are matrilocal and have less than occasional warfare, father's sleeping distance will be a better predictor of homicide and assault (305).Ember, Carol R. - Father absence and male aggression: a re-examination of the comparative evidence, 2002 - 4 Variables

    This paper supports Beatrice B. Whiting's (1965) sex-identity conflict hypothesis which suggests a relationship between males' early identification with their mothers and male violence. Authors find that, in addition to socialization aggression, frequency of homicide/assault is significantly related to father-infant sleeping distance, particularly when residence is not matrilocal and/or warfare is more than occasional.

  9. Lower frequency of internal war will be correlated with more ritual art.Fullerton, Brady - Does Art Bring Us Together? An Empirical Approach to the Evolutionary Aesthe..., 2020 - 2 Variables

    In this study, the author empirically tests a formulation of Ellen Dissanayake's evolutionary theory of art, which argues that art evolved to promote group cohesion. The hypotheses derived from this theory and tested in this study specifically focus on ritual art and its relationships to various proxies for group cohesion such as community conflict and internal warfare. Results show that the presence of ritual art is significantly higher where certain measures of group cohesion are also higher (including lower internal warfare, lower conflict between communities of the same society, and lower frequency of violent conflict between groups within local communities).

  10. Male aggressiveness was the strongest predictor of degree of polygyny, when tested against father-infant proximity, male contribution to subsistence, and male aggressiveness (55).Marlowe, Frank W. - Paternal investment and the human mating system, 2000 - 4 Variables

    This article explores the interrelated roles of male parental investment (males' infant/child care and resource provisioning) and male-male competition (variation in male status) on the degree of monogamy or polygyny in a society. Marlowe argues that Degree of parental investment affects females' interest in resource-shopping versus gene-shopping. Also discussed is the idea that male-male competition affects males' inclination toward harem-defense or coercive polygyny. Particular attention is paid to variation in parental investment and male stratification across subsistence types.
