  1. "As pathogen severity increases, so should permanenent marking of body areas that are attended to for evaluating attractiveness and mate quality" (403).Singh, Devendra - Sex differences in the anatomical locations of human body scarification and ..., 1997 - 6 Variables

    This study examines the relationship between body scarification and pathogen prevalence. Authors hypothesize that risk of serious pathogens will be related to scarification on areas of the body that are associated with physical attractiveness and fertility. Results show that only female stomach scarification is significantly related to pathogen prevalence.

  2. Male characters will be significantly more likely to use physical attractiveness as a criterion for mate choice than females (107).Gottschall, Jonathan - Sex differences in mate choice criteria are reflected in folktales from arou..., 2004 - 2 Variables

    This article expands on Buss's (1989) study of the differences in male and female mate preferences in Western folktale characters by adding non-Western data. The new results show support for Buss's original findings.

  3. Societies with cousin marriage will have more pathogen stress than those without cousin marriage (5,6).Hoben, Ashley D. - Factors influencing the allowance of cousin marriages in the Standard Cross ..., 2016 - 2 Variables

    The authors investigate environmental reasons for cross-cultural variation in the permissibility of cousin marriages. In particular, they test whether higher levels of pathogen prevalence and geographic isolation increase the likelihood that cousin marriage will be allowed. The authors' underlying theory is that cousin marriages provide protective homozygosity against some pathogens and provide more options when mate choices are limited.

  4. Adults will be healthier in societies located in high latitudes than those in low latitudes (235).Whiting, Marjorie Grant - A Cross-Cultural Nutrition Survey of 118 Societies, Representing the Major C..., 1958 - 2 Variables

    Dietary variation has been implicated in population-level heath outcomes such as adult height and infant health. Here the author investigates these relationships in a sample of 118 nonindustrial societies, providing a comparative and quantitative assessment of nutrition and health cross-culturally.

  5. Socialization for collectivist values will be associated with pathogen prevalence, population density, and levels of political integration (68).Cashdan, Elizabeth - Pathogen prevalence, group bias, and collectivism in the standard cross-cult..., 2013 - 4 Variables

    This article investigates how pathogen risk affects xenophobia, in-group bias, and collectivist and conformist values. Data analysis suggests that there is an association between pathogen risk and socialization for collectivist values, but the other variables were not associated with pathogen prevalence.

  6. Toxicity will be associated with levels of cassava consumption (p.105).Romanoff, Steven - Cassava production and processing in a cross-cultural sample of african soci..., 1992 - 4 Variables

    This exploratory study seeks to explain cassava production and processing in Africa by considering cultural, agronomic, and environmental data. After examining the descriptive results of the agricultural and social contexts of cassava use, the authors build upon Boserup's population density model (1965) to analyze their own hypothesized model of cassava's importance among the sampled societies.

  7. Location (latitude) was significantly related to rates of intergroup differentiation in the 1970s (3).Van de Vliert, Evert - The global ecology of differentiation between us and them, 2019 - 3 Variables

    In this article the researcher conducted five different studies on in-group or "we-group" vs out-group or "they-group" discrimination practices. Two previous hypotheses are re-examined, the pathogen stress hypothesis and the rice-wheat hypothesis, in order to explain heightened ingroup-outgroup differentiation, before turning to overarching geographical hypothesis. Each of the five studies look at a different group of societies cross-culturally, ending in an index of intergroup discrimination by individuals across 222 countries in study 5. All five studies conclude that differentiation between us and them varies based on geographical location and more specifically, along latitude.

  8. Both male and female characters will prioritize kindess as a criterion for mate preference (108).Gottschall, Jonathan - Sex differences in mate choice criteria are reflected in folktales from arou..., 2004 - 2 Variables

    This article expands on Buss's (1989) study of the differences in male and female mate preferences in Western folktale characters by adding non-Western data. The new results show support for Buss's original findings.

  9. Where serious pathogens are prevalent and severe, there will likely be increased polygyny (116).Low, Bobbi S. - Pathogen stress and polygyny in humans, 1987 - 2 Variables

    This study tests the association between pathogen risk and degree of polygyny and sexual advertisement. Results show that the greater the risk of serious pathogens, the greater the degree of polygyny. The correlation between pathogen risk and sexual signals is only marginally significant. An association between mate choice and resource control is also examined.

  10. Degree of technological adoption in 1000 BCE, 0 BCE, and 1500 BCE is positively associated with per capita income and technological development in 2002 (66).Comin, Diego - Was the Wealth of Nations determined in 1000 BC?, 2010 - 5 Variables

    The authors explore the relationship between differences in technology adoption across cultures in snapshots from 1000 BCE, 0 CE, 1500 CE, and 2002 CE. While acknowledging various flaws inherent in the ambitious scope of their dataset, a significant relationship is nonetheless revealed between technology adoption in 1500 CE and technology and income in 2002 CE after controlling for various geographic and demographic factors. The authors suggest that this persistence may occur because technology adoption is heavily dependent on stock of prior technology.
