The authors investigate whether moralizing high gods and, more generally, supernatural punishment precede, sustain, or follow political complexity. The cultural traits at hand are mapped onto phylogenetic trees representing the descent and relatedness of 96 Austronesian cultures.

Using 57 cultures from the Human Relations Area Files database, this paper examines the function and effectiveness of the belief of punitive ancestors in small-scale societies. The authors found that belief in dangerous ancestral entities is widespread and common and that harm is preventable through ritualized mortuary practices. The authors concluded that the fear of ancestral spirits did not promote social cooperation or inhibit self-interest behavior, contrary to the supernatural punishment hypothesis.

Researchers tackle the moral gods hypothesis which proposes that moral gods enabled large-scale societies to evolve. They use 414 societies spanning 10,000 years in Seshat: Global History Databank and code 51 measures of social complexity and four measures of moral gods. The findings of the present study challenge the moral gods hypothesis. In the societies studied, complex societies appear to precede moral gods rather than the inverse of moral gods preceding complex societies.

Stark attempts to resituate Tylor's formulation of religion by calling into question Swanson's (1960) and Peregrine's (1996) findings that supernatural sanctions and moral behavior are consistently correlated in small-scale societies. Positing that Swanson's correlations were confounded by variables related to cultural complexity, Stark tests the association of presence of moralizing Gods with cultural complexity explicitly, as well as measures of morality in various nations as provided by the World Values Survey (1990-1991). The robust correlations across cultures noted below, as well as cross-national findings, provide support for the researcher's theory that it is particular conceptions of God rather than participation in rites and rituals which empower religion to sustain complex moral culture.

Researchers sampled 106 Austronesian societies from the Pulotu database to study the way political complexity evolves in relation to religious beliefs and practices. Specifically, they attempt to test the causal theory that supernatural punishment played a causal role in the emergence of large, complex societies. They use phylogenetic models to control for Galton's Problem in testing the supernatural punishment hypothesis in an effort to demonstrate the effectiveness of utilizing cross-cultural datasets in evaluating evolutionary change in human social organization.

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.

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.

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.

A previous study conducted by Singh (2017) investigates why and how features of shamanism have culturally evolved, one such feature being shamanistic trance. However, the authors of this article argue that Singh fails to distinguish between different types of shamanistic trance. They find that possession trance, as compared to trance without possession, is primarily dominated by females and found in complex societies.

Does belief in moralizing and punitive gods promote sociality between coreligionists who are otherwise strangers? A recent dataset of behavioral economic experiment results and demographic and religious data among eight disparate populations allows the researchers to test their hypothesis of a positive association between deity's perceived interest in human morality and favorability of treatment of outsiders who share a religion. Their findings mostly support this hypothesis, which they suggest lends credibility to a theory in which religion encourages cooperation between large groups of people, and is thus a successful product of cultural evolution.
