The researchers use phylogenetic methods to map out the evolutionary trajectories of land tenure norms across 97 Austronesian societies. The analysis suggests the relevance of vertical transmission in patterning land tenure norms, rather than horizontal transmission. It also strongly supports a model along a N(none)-I(individual)-G(group)-K(kin) pathway.

In this paper, the authors utilize phylogenetic methods to reconstruct the evolution of land tenure norms among 97 Austronesian societies. They coded these norms for each society as none (N), group (G), group-kin (K), and individual (I). After formulating various models of evolution through these various stages, they used Bayesian analysis to determine support for each. They conclude with remarks about this type of evolutionary phylogenetic research as a form of "virtual archeology."

This article explores differences between "tight" cultures ("have many strong norms and low tolerance of deviant behavior") and "loose" cultures ("have weak social norms and high tolerance of deviant behavior"). The tightness-looseness measure manifests in a myriad of macro and micro phenomena, from governance and religiosity to individual psychological processes. This study investigates these phenomena in modern nations rather than traditional societies. Potential ecological, historical, and socio-political predictors of tightness-looseness are also examined.

This article examines the relationship between the tightness-looseness of a culture and the variation of COVID-19 cases and deaths through October 2020. With COVID-19 data retrieved from Our World in Data from 57 countries with tightness-looseness figures, the article found the cultures with high levels of tightness had fewer COVID-19 cases and deaths when compared to countries with high levels of looseness. Results suggest support of the evolutionary game theoretic model proposing that people in tight cultures may cooperate with more urgency when under collective threat than people in loose cultures.

Researchers looked at 180 of the 186 societies in the SCCS for changes over time in lineage systems. The goal was to estimate the frequency of transitions away from and to matriliny cross-culturally, as well as explore the potential causes of these patterns / transitions. The study focused on two overarching research questions: 1. How common are transitions away from matriliny and how often do ‘reverse transitions’ to matriliny occur? 2. What causes transitions to or from matriliny? Overall, the study found that transitions away from matriliny have been quite common within the time frames covered by the ethnographic samples available, while transitions from another system to matrility have been rare. In answering the second question, the researchers report the highest correlation is between subsistence transitions (towards pastoralism, intensive agriculture, or a market economy) and lineage transitions (away from matriliny) as well as between higher levels of social complexity (measured by stratification, slavery, and population size) and lineage transitions (away from matriliny).

This study is a reexamination of Bacon's (1965) previous cross-cultural study regarding drinking. The current study supports the dependency-conflict hypothesis that frequency of drunkenness is related to dependency needs in childhood and adulthood.

Female aggression, reasons and targets of that aggression are described using a cross-cultural sample. It is suggested that female aggression is often a means of competing for men or subsistence products, but it also may be a means of defense.

Causal factors to the development of crime are examined. Frequency of theft and personal crime are tested against these causal factors in a search for correlations.

Textor's (1967) A Cross-Cultural Summary is used to test a variety of Sauer's (1952) hypotheses concerning the sequence of agricultural developments. Tests are primarily focused on subsistence variables.

A study of the relationship between older women and their young female kin. Relationships between women's relationships with their mother-in-laws and subsistence contribution, residence, descent, and food preparation are examined. Findings offer significant support for patterns in the relationship between older women and younger female kin.
