  1. Cooperation and trust across societies during the COVID-19 pandemicRomano, Angelo - Journal of Cross-Cultural Psychology, 2021 - 5 Hypotheses

    Researchers used various hypotheses to determine if cross-country differences in trust and cooperation would predict prosocial COVID-19 responses and policies. Using individual surveys from 34,526 participants from 41 countries, there were no significant associations between trust and cooperation and prosocial behavior, motivation, regulation, or stringency of policies. While the researchers did find significant variation among cross-country individuals, these results were unable to predict country-level prosocial responses.

  2. The modern impact of precolonial centralization in AfricaGennaioli, Nicola - Journal of Economic Growth, 2007 - 1 Hypotheses

    In this study, the authors empirically assess the relationship between precolonial centralization and the implementation of modernization programs by African governments. Their findings indicate that current African countries tend to have better provisioning of public goods (including better access to education, healthcare, and infrastructure) when their ethnic groups' precolonial institutions were more centralized.

  3. Demand for Vaccination in Sub-Saharan Africa: The Vertical Legacy of the Slave TradeAthias, Laure - Social Science & Medicine, 2022 - 6 Hypotheses

    The authors of this study integrate recent data with data on ancestral ethnic groups' exposure to the slave trade in order to examine the relationship between this historical exposure and children vaccination status against measles. They find evidence to support their hypothesis that children from mothers whose ancestors belonged to an ethnic group that exported slaves are less likely to be vaccinated against measles, theorizing that this correlation stems from distrust in medical and governmental institutions. Supporting this theory, they also find that groups historically exposed to the slave trade that have higher preference for traditional practices are even less likely to vaccinate their children against measles.

  4. Socio-cultural values are risk factors for COVID-19-related mortalityEndress, Ansgar D. - Cross-Cultural Research, 2022 - 2 Hypotheses

    This paper proposes that the socio-cultural values of countries may be associated with increased mortality due to COVID-19. Using results from the World Values survey, the author assessed which values had the strongest association with a change in COVID-19 mortality in datasets consisting of all countries, upper-middle and high income economies, upper-middle income economies, high income economies, and advanced economies. The author also sought to determine whether the WVS values that were associated with COVID-19 mortality were also associated with general life expectancy. The results showed that COVID-19 mortality was increased in countries that placed a higher value on freedom of speech, political participation, religion, technocracy, post-materialism, social tolerance, law and order, and acceptance of authority. On the other hand, mortality was decreased in countries with high trust in major companies and institutions and that endorsed maintenance of order as a goal for a country. The author also found that values related to COVID-19 mortality did not predict general health outcomes, and that some values that predicted increased COVID-19 mortality actually predicted decreased mortality from other outcomes.

  5. Culture and National well-being: should societies emphasize freedom or constraint?Harrington, Jesse R. - PLoS ONE, 2015 - 9 Hypotheses

    The purpose of the present study is to provide insight on the debate concerning how best to organize societies: with more freedom (looseness) or with more constraint (tightness). In a comparison of 32 nations, Harrington, Boski, and Gelfand examine the relationship between tightness/looseness and three dimensions of societal well-being: psychosocial, health, and political/economic outcomes. Findings indicate that excessive constraint and/or freedom contribute to poorer psychosocial, health, and economic/political outcomes, as well as overall national-level well-being. These results suggest that a balance of freedom and constraint is associated with optimal societal well-being.

  6. Tightness-looseness across the 50 united statesHarrington, Jesse R. - Proceedings of the National Academy of Sciences, 2014 - 4 Hypotheses

    Authors contend that many of the differences across the 50 states can be attributed to the degree to which social entities are "tight" (have many strongly enforced rules and little tolerance to deviance) or "loose" (have few strongly enforced rules and greater tolerance for deviance). Significant correlations were found between many state characteristics and tightness-looseness.

  7. Adolescent fertility and risky environments: a population-level perspective across the lifespanPlacek, Caitlyn D. - Proceedings of the Royal Society B, 2012 - 3 Hypotheses

    This study provides the first tests of the relationships between population-level adolescent fertility rates and mortality risk at two different time points. The hypotheses are based in life-history theory, which predicts that human reproductive choices are shaped by mortality. The authors find that reproductive strategies are significantly predicted by both early (between ages 1-7) risks of mortality and current cues of mortality risk.

  8. Why on earth?: Evaluating hypotheses about the physiological functions of human geophagyYoung, Sera L. - The Quarterly Review of Biology, 2011 - 5 Hypotheses

    The author tests various hypotheses regarding cross-cultural occurrence of geophagy, the eating of earth. Nearly 500 years of references to geophagy were compiled into the Database on Human Geophagy, which was then used to examine biological justifications for this little-understood behavior.

  9. Preferred interpersonal distances: A global comparisonSorokowska, Agnieszka - Journal of Cross-Cultural Psychology, 2017 - 4 Hypotheses

    The authors assess and compare preferred interpersonal distances over 42 countries. Environmental and sociopsychological factors are tested in order to explain variability in interpersonal distance across cultures. The authors seek to go beyond previous studies and better understand cultural differences and similarities in proxemic behaviors.

  10. Norms of premarital sexual behavior: a cross-cultural studyBroude, Gwen J. - Ethos, 1975 - 5 Hypotheses

    This article examines correlates of premarital sexual norms cross-culturally. Several explainations of restrictiveness of premarital sex are reviewed, and results indicate that accessibility of caretakers in childhood, class stratification and cultural complexity are all related to premarital sexual norms.
