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.

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.

This study analyzes the relationship between game complexity and sociocultural complexity. Significant relationships were found between several aspects of complexity and game complexity.

This article reviews literature on social evolution, urbanization, and their interrelationships before empirically examining the relationship between settlement size and organizational complexity. An index of social development composed of three indicators is introduced, critiqued, and compared to other classification systems.

This study tests the relationship between supernatural punishment (indexed by the importance of moralizing "high gods") and several proxy measures of cooperation. Results suggest that the presence of high gods is associated with money and credit, credit source, community size, jurisdictional hierarchy beyond the local community, and sanctions.

For thousands of years, scholars have been theorizing about why human groups structure themselves the way they do, allowing more power and freedom to certain individuals and less to others. This article takes an evolutionist approach to that question, using a variety of mathematical models to predict changes in social organization throughout the evolutionary history of humanity and its ancestors, accounting for changes in brain size and global human populations. The authors validate their models using data from the ethnographic record. In general, they find that tendency towards hierarchy decreases with bigger brain size but increases with global population growth.

This paper examines the relationship between moralizing gods (gods that impose moral rules or punish those who break them) and social complexity. The authors argue that previous research, which relied on the Standard Cross-Cultural Sample's "moralizing high gods" variable as a proxy measure for the presence of moralizing gods, may have underestimated the presence of moralizing gods in societies. This is because the criteria used to define "moralizing high gods" are not relevant to whether a god is moralistic or punitive. The authors argue that this leads to a false positive association between moralizing gods and social complexity, and that ethnographic evidence suggests that moralizing gods are actually more prevalent in small-scale societies than had previously been thought. Future researchers, therefore, need to be careful about making assumptions about the moralizing gods of small scale societies based on "moralizing high gods", and find other ways to identify whether moralizing gods are present.

This article explores the relationship between language structure and social environment, positing that linguistic factors such as morphological complexity are associated with demographic/socio-historical factors such as number of speakers, geographic spread, and degree of language contact. Data support such an association. The authors further propose a Linguistic Niche Hypothesis suggesting that “the level of morphological specialization is a product of languages adapting to the learning constraints and the unique communicative needs of the speaker population” (7).
