After studying Paiute society, the author postulates that sorcery may serve as a mechanism for social control in societies lacking superordinate authority justice. In this chapter, the cross-cultural results were presented.

This study examines husband-wife relationships, specifically rooming and sleeping arrangements, as they relate to variables such as infant care, subsistence, residence, and cultural complexity. Several hypotheses are tested and all are supported.

This article examines the relationship between population size (and complexity) and the level of third-party punishment in economic games. Results demonstrate that people in larger, more complex societies engage in significantly more third-party punishment than people in small-scale societies.

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.

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.
