This paper adds to a body of research which analyzes the persistence of institutional features in societies over time by testing for association between local democracy (succession by consensus among preindustrial groups) and various measures of democracy in contemporary societies. The researchers conclude that beliefs and values which perceive democracy as a viable political structure may be an important mediating mechanism in producing and maintaining democratic instututions over time.

While it is widely accepted that there are a multitude of variables that contribute to a society’s level of democracy, the authors of this study argue that the prevalence of consanguinity is one that is often overlooked. Using a sample of 70 nations, they tested the relationship between consanguinity (defined as marriage and subsequent mating between second cousins or closer relatives) and level of democracy (defined by both the Polity IV scale and the EIU Index) and found a significant negative relationship. Similarly, when controlled for a host of different variables in multiple regression analysis, the significant relationship between consanguinity and level of democracy held true.

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.

Using a new expert survey, the authors explore the democraticness of traditional political systems (TPS) in 159 ethnic groups in Africa. Their initial analysis finds that measures of public preference input and political process control are particularly strong contributors to the degree that a society may develop democracy in their TPS. They also find that societies with powerful elders are more likely to be democratic, while more hierarchically organized political systems and those with kings, chiefs, and segmentary lineages are less likely.

This study investigates the relationship between domestic organization (i.e. family structure and size) and democracy at both the communal and supracommunal levels. The authors suggest that the prevalence of independent monogamous families in Europe in the Late Middle Ages may have facilitated the political evolution toward democracy.

The author analyzes 440 Sub-Saharan African societies to test whether trade across ecologically diverse zones is predictive of degree of state centralization (state capacity or strength of state) in pre-colonial Africa. The author finds that diverse ecology is predictive of state capacity and that trade supports class stratification. The author also emphasizes the importance of historical contingency and ethnographic data consultation in understanding mechanisms in individual cases.

This paper seeks to understand the extent to which religion has been used to legitimize political power in the past, and the extent to which that carries into contemporary institutions. The authors seek to demonstrate that there is a strong link between the stratification of societies in the past and the presence of autocracies in many of those same areas today. They make their case by putting forward, and testing, three linked theories -- first, that stratified societies are more likely to develop religions based on moralizing high gods as a means of divine legitimization, second, that the societies that used religion for legitimacy in their past are more likely to have religion embedded in their institutions today, and third, that societies that used religion for legitimacy in the past are more likely to be autocracies today.

This study proposes that polygyny, unilineal descent organization and large extended families could be regarded as universal negative predictors of communal democracy. Crosstabulations show that Christianity is positively associated with communal democracy and negatively associated with polygyny, and thus the authors suggest that Christianity influenced the development of democracy in Europe through its discouraging of polygyny and unilineal descent organization.

The present study attempts to replicate the Barber (2011) finding that more considerable security influences a country's disbelief in God. However, this research uses a more diverse sample and seeks to answer additional questions about religiosity and security than the previous work. The results are in line with all of the predictions and offer extra support to the uncertainty hypothesis.

This paper introduces a typology that “classifies collectivities according to fundamentals of their organization for making decisions and taking action” (607). Analysis focuses on the constitutional system and its relationship with need achievement and narcissism. Hypotheses are supported.
