The second and third parts of this book classify the economic systems of foraging and agricultural societies in the SCCS based on correlations between their institutions of property an distribution. These economic types are then examined for relationships with other social, political, demographic, and environmental factors in order to draw tentative conclusions regarding the origins of the Agricultural and Industrial Revolutions. The fourth part of the book uses cross-national data to examine similar associations in industrial/service economies, and is not included here.

Derived from the fear of supernatural punishment hypothesis, this paper explores whether the prosocial attitude of a group or individuals will increase with the threat of punishment from a high god or visible supernatural agent, such as sorcerers and witches. The author found that fear of supernatural punishment did not affect prosocial behavior and suggested that religious beliefs may give rise to institutions with the task of enforcing social compliance rather than direct control.

This chapter examines the variables that are associated with the evil eye belief cross-culturally. Results suggest that the evil eye belief is significantly associated with various socioeconomic and demographic variables. All hypotheses are supported.

A restudy of Naroll's (1962) measure of dwelling floor area using theory that it is predicted by the basic needs for protection from climate and crowding. This theory is not supported by the findings but Brown posits a new average for estimating floor area in dwellings based on his sample.

This article investigates relationships among society size, war and conflict, preferred habitats, and belief in moralizing gods. The authors discuss morality and collective action in the face of natural disasters and competition for resources, theorizing that beliefs in moralizing gods could facilitate such cooperation.

This study exmaines the presence of High Gods in societies as a function of subsistence type, population size, and stratification. High Gods are thought to be a mechanism to encourage collective action in the face of environmental challenges. Animal husbandry was found to be a strong predictor of High Gods, especially gods that are active in human affairs or morally supportive.

How did moralizing religions rise, and what have they caused? The authors test the Big Gods theory, which suggests moralizing religions as a predictor of large-scale complex societies. In addition, they propose their hypothesis, which indicates that warfare, animal husbandry, and agricultural productivity have a role in producing moralizing religions. The results show no significant support for the Big Gods hypothesis. However, they support intergroup warfare, particularly military technologies and cavalry, as an important predictor of social complexity and moralizing religions. In addition, pastoralism has a moderate effect as a predictor for the rise of moralizing religions.

This article builds on previous cross-country and cross-state research into Tightness-Looseness (TL) theory, which proposes relationships between the incidence of ecological threat and cultural tightness, as well as tightness’ downstream effects on belief in a moralizing high god, inter-group contact and authoritarian leadership. To evaluate the generalizability of TL theory beyond complex cultures, the authors test these relationships among 86 nonindustrial societies from the ethnographic record. A structural equation model is presented of the results for nonindustrial societies; it is generally in accord with previous findings from more complex societies. Because the nonindustrial sample is more variable, they also look at relationships between societal complexity and kinship heterogeneity, aspects that vary in nonindustrial societies.

In this study, the authors examine pathways to social inequality, specifically social class hierarchy, in 408 non-industrial societies. In a path model, they find social class hierarchy to be directly associated with increased population size, intensive agriculture and large animal husbandry, real property inheritance (unigeniture) and hereditary political succession, with an overall R-squared of 0.45. They conclude that a complex web of effects consisting of environmental variables, mediated by resource intensification, wealth transmission variables, and population size all shape social inequality.

Belief in moralizing high gods (MHGs) has been theorized as a response to unfavorable environments, as a way to normalize behavior. In this study, researchers test the theory by creating a model for predicting the distribution of MHGs. They run many alternative models, testing the effects of resource abundance, climate stability, and pertinent social factors on the occurrence of belief in MHGs. Based on the ten most supported models, they create an average model that predicts MHGs within cultures with “excellent” accuracy.
