This article investigates a broad hypothesis that cultural traits diversify with sociocultural development. Results suggest that sociocultual development is associated with certain aspects of aesthetic and ritual culture, and that cultural elaboration may be correlated with some sexual norms and tendency toward cannibalism, human sacrifice, and slavery.

Using principal-components analysis, the author develops an Index of Sociocultural Development that measures the same concepts as Carneiro’s Index of Cultural Accumulation. Carneiro’s index also contains a measure of cultural elaboration which the author suggests examining further.

This article proposes three stages of slavery: dominance slavery, temporary decline of slavery, and economic slavery. Dominance slavery refers to the enslavement of war captives while economic slavery entails a legally codified slave class in a more economically stratified society. Mann-Whitney summed-rank tests suggest that economic slavery is associated with higher socioeconomic development, here defined in terms of male-dominance rather than equidominance in a society.

Humans, just like other mammals, tend to allow greater sexual freedom for men rather than women. Furthermore, females are burdened with the majority of parenting. Do parenting costs limit sexual unrestrictedness to a different degree for males and females? The authors find that across 48 cultures, as women’s parenting costs decreased through improved physiological and economic conditions, women’s sexual unrestrictedness increased.

This paper is concerned with the variation in sexual behavior in humans. Authors test hypotheses regarding the relationships between sexual behaviors and beliefs concerning sex.

This study investigates the role of economic development in facilitating political development in preindustrial societies, theorizing that the redistribution of resources is an important factor in this relationship. Results indicate that these two types of development have a curvilinear relationship, and the author concludes that economic development is a necessary but not sufficient cause of political development in preindustrial societies.
