This article used sub-national, historical and cross-country data to examine if exposure to ultraviolet radiation (UV-R) could be a factor in the formation of individualism and collectivism. The study found support, across all data sets, that increased exposure to UV-R is associated to more collectivism within a culture. The authors theorized that UV-R exposure increases the likelihood of eye disease causing higher rates of blindness. With increased levels of blindness, the more emphasis there will be on close family relations and/or increased uncertainty avoidance from out-groups leading to more collectivism in a culture.

While a growing body of research being conducted in Western societies suggests that both religious/spiritual (R/S) and so-called “pro-science” belief systems are correlated with better health and well-being, a widespread perception also exists that these two categories of belief systems are fundamentally incompatible. This article tests that perception. The authors finds that cross-culturally – and particularly outside of modern Western societies – it is largely incorrect. Rather, around the world individuals adhere to both R/S and pro-science belief systems at the same time, and often benefit from both of them.

This article focuses on the relationship between the use of physical punishment during child socialization and the amount of supervision that adults experience. The authors analyze data using a path analysis which suggests that the greater the valuation of conformity relative to self-reliance, the greater the use of physical punishment during child socialization. Precursors of conformity are also suggested.

In this study, the authors examine pathways to social inequality, specifically social class hierarchy, in 408 non-industrial societies. In a path model, they find social class hierarchy to be directly associated with increased population size, intensive agriculture and large animal husbandry, real property inheritance (unigeniture) and hereditary political succession, with an overall R-squared of 0.45. They conclude that a complex web of effects consisting of environmental variables, mediated by resource intensification, wealth transmission variables, and population size all shape social inequality.

This study explores predictors of variation in two dimensions of marital residence patterns among hunter-gatherers: 1) the tendency toward patrilocality versus matrilocality and 2) the tendency toward unilocality versus bilocality.

The present research investigates food sharing and labor sharing practices of 98 nonindustrial societies. The aims are to: 1) document the frequency and scope of sharing, and 2) test the theory that greater sharing is adaptive in societies subject to more resource stress (including natural hazards).

This article discusses constraints on role behavior that affect the division of labor, focusing on women’s childcare responsibilities, the nature of production sequences, and occupational specialization. The authors employ entailment analysis to examine 50 activities; results suggest three findings: 1) men are more likely to be assigned tasks that require travel and exposure to danger, 2) men are more likely to perform tasks that are early in the production sequence, and 3) if women perform a task at an early stage of production, they are more likely to perform subsequent tasks.

This article reviews theories of marital power and tests for a relationship between wives’ contribution to subsistence and their conjugal power in patriarchal cultures. Results indicate a positive association. The role of cultural complexity is also considered; its relationship with wives’ power is negative and linear while its relationship with wives’ contribution to subsistence is negative and non-linear.

Using a cross-cultural sample of 91 societies, this paper draws on ecological theory to test if unpredictable environments will favor subsistence diversification. The general hypothesis is that societies with high climate unpredictability and resource stress would exhibit more subsistence diversity than societies in more stable climates. The authors examined four environmental and resource stress variables while controlling for temperature variance, subsistence activity, and phylogeny. Support was found for 2 of the 4 variables--chronic scarcity and environmental instability. In the discussion they suggest that more commonly observed events (e.g. annual hunger and climate unpredictability) may give people more motivation to change subsistence than rarer events (e.g. natural hazards and famine).

Economic growth has often been viewed as a pathway to improving human wellbeing, yet increases in wealth have not consistently translated into greater emotional wellbeing. This study examines the hypothesis that populations with greater ancestral ties to hunter-gatherer societies will report higher levels of wellbeing. To test this hypothesis, the author constructed a country-level measure of gatherer ancestry using data from 1,265 small-scale societies in the Murdock Ethnographic Atlas and compared it with national measures of happiness and life satisfaction from the World Values Survey across 104 countries between 1981 and 2014. Regression analyses controlling for income per capita and a broad range of historical and contemporary covariates found that gatherer ancestry was a significant positive predictor of happiness (β = 13.58, SE = 3.00, p < .01; model R² = 11.8%). These findings remained robust across multiple models, suggesting that characteristics associated with hunter-gatherer lifeways may provide important insights into the social and ecological conditions that promote human emotional wellbeing.
