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.

The authors propose that societies with a tradition of rice farming are less likely to develop a democracy than societies with a tradition of wheat farming. They base their predictions on the theory that wheat farming, as opposed to rice farming, does not require extensive community collaboration and promotes individualism, which then in turn promotes democracy. Their findings were robustly consistent with their predictions. The authors used multiple controls in their analyses, including religion, economic development, geography, and local democratic practices.

Drawing from risk sharing theory, this paper used data from 89 countries to examine the relationship between historic rainfall variation (before 1900) and the emergence of collectivism in, assumed to be, preindustrial societies. Contemporary values of individualistic responsibilities were used under the assumption that they will reflect preindustrial values. Findings support the hypothesis that countries with greater rainfall variation will have less individualism than countries with less rainfall variation. The author then examined rainfall variation and individual responsibility as a proposed catalyst for economic development. Support was found that as individualism increased, so did the economic development of a country.

A small sample (16 cultures) is used to examine the influence of cultural variables on the psychological constructs of self-concept and causal attributions. Results suggest that valued goals (collectivism vs. individualism) and group norms (tightness vs. looseness) both influence self-concept and causal attributions.

This study analyzes Weber's religious ethic thesis by investigating the relationship of religiosity on economic, social, and expressive individualism. The author found that religiosity increased economic individualism, and decreased social and expressive individualism. Under the notion that natural disasters prompt collectivistic defensive mechanisms, the author demonstrated some support that low levels of pathogen prevalence strengthened religiosity's relationships with social and expressive individualism, but not for economic individualism. The author did not find support for Weber's idea that Protestation will increase economic individualism and other religions, such as Islam, decrease economic individualism.
