This paper "reduces Murdock's 210 categories to 30 variables, and intercorrelates and factor analyzes the variables for six world subdivisions as well as for the entire world." This article also discusses factor analysis as a method and examines the correlations more closely between the two regions that differed the most, North America and the Circum-Mediterranean.

Expanding on the author’s previous findings, this article examines the social and economic variables that may explain the cultural evolution of religious practitioners. With a 47 society sample, the author found that subsistence activities and socio-political conditions predict magico-religious practitioner types (sorcerers/witches, priests, shamanistic healers, mediums, healers, shaman/healers, and shamans) with the strongest results being from subsistence and political organization. He then used these findings to theorize about the biogenetic bases of religion in societies.

This chapter explores and tests some propositions about matrilineal societies. Supplementary to that discussion, the author also explores the problems of method associated with the use of coded data on large samples of cultures.

The authors examine correlations between slavery and variables that can potentially be detected archaeologically. The authors do not test specific hypotheses, but aim to explore the variables in a broader sense. As such, the authors use a grounded theory approach to data analysis in order to examine trends that emerge from the data itself.

This study challenges an earlier paper's claim that matrilocal residence predicts the development of girls' puberty rites. The author suggests that girls' puberty rites may in fact predate matrilocality in some locations.

This article re-examines previous hypotheses by Tylor regarding kin avoidance behavior. The author tests hypotheses on a sample of North American societies that accounts for genetic language families. Results provide partial support for hypotheses.

This study uses a multiple regression analysis to examine the relationship between society type and several variables of societal organization. Results suggest that limited family type is more likely to be found in complex societies.
