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.

The authors of this article evaluate how the legacies of early statehood (i.e., precolonial centralized ethnic groups) in Africa continue to impact democratic governance. They find a positive relationship between early states and support for autocratic rule, especially in former British colonies that were highly centralized prior to colonization. They suggest that the transmission of political and cultural norms play an important role in the support for autocracies.

The researchers test the relationship between political complexity among African pre-colonial ethnic institutions and contemporary economic performance (using light-density data as a proxy). Their tests yield a robust positive association even after controlling for multiple alternative geographic, cultural, and economic variables, which they interpret as underscoring the ongoing importance of ethnic-specific institutions in shaping economic activity in contemporary Africa.

The authors of this study examine the relationships between historical exposure to Islamic kingdoms and current economic, medical, and educational development in Africa. They predict that ethnic groups that were previously ruled by Islamic states or chiefdoms will have worse outcomes today, theorizing that these worse outcomes would be not as a result of an inherent characteristic of Islam or Islamic kingdoms themselves but rather decreased investment by colonial states or missions. Their results lend some support to their hypotheses, and particularly to the predictions that Christian missions and colonial states would not be able to penetrate areas under Islamic influence as easily as other regions.

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.

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 study examines socio-economic predictors of political complexity. Findings suggest that class stratification is the most significant predictor of political complexity.

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.

This article examines the evolution of games, particularly the way the complexity of games is affected by political organization, demographics, social differentiation, and religious differentiation.

The present study investigates whether there is resilience variability following climate-related disasters in societies that are corporate-oriented, which promote participatory and inclusive structures, and exclusionary-oriented, which limit political authority and power. The findings offer modest support for social resilience theory that more flexible (i.e. more participatory) societies would be more resilient after a disaster than less flexible societies. Although only 5 of 14 correlations are significant, the direction is significant by a binomial sign test.
