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.

This paper suggests that ancestral irrigation is linked to lower levels of contemporary female labor force participation. The hypothesis is tested using cross-country data, as well as data from various surveys. The study finds evidence that the gender-based division of labor in pre-modern agriculture may be the mechanism behind this relationship, and that cultural transmission across generations, particularly through males, may play a role in perpetuating this pattern.

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.

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.
