Using frequentist and Bayesian multi-level models in a sample of two international samples, the authors test whether there are significant sex differences in moral judgments across a large-scale examination of countries. They compare men and women using the five components of the Moral Foundations Theory: 1) care, (2) fairness, (3) loyalty, (4) authority, and (5) purity. In addition, they study the differences when considering socioeconomic and gender-equality status. The results partially support the presence of significant sex differences. While care, fairness, and purity were consistently higher for women; loyalty and authority were highly variable. The study also shows that there are larger sex differences in moral judgments across more individualist, WEIRD, and gender-equal societies.

The article discusses the role of gender in within-society variation in cooperative behavior, and whether gender differences in cooperation emerge similarly across diverse societies. The authors use cross-cultural datasets of 4- to 15-year-old children's preferences for equality in experimental tasks measuring prosociality and fairness to investigate these questions. They find that gender has little impact on the development of prosociality and fairness within the datasets, and there is not much evidence for substantial societal variation in gender differences. The authors discuss the implications of these findings for understanding the nature and origin of gender differences in cooperation and for future research.

This book examines population growth rate and its correlates by testing 274 hypotheses (derived from multiple theories) with an 18-society sample. Forty-one of these hypotheses were significant at the .05 level, leading the author to accept these relationships as reflective of the real world. The 274 hypotheses are grouped into 51 broader hypotheses, and marked by (*) where relationships are significant as designated by the author or by significance p < 0.05.

This paper seeks to understand how the conflict resolution strategies of indigenous and non-indigenous groups differ in their efficacy. The authors suggest that indigenous methods of conflict resolution are more effective than non-indigenous methods by demonstrating that subjects from the Outline of Cultural Materials (OCM) associated with indigenous conflict management (ICM) will co-occur less frequently with OCM terms related to conflict than subjects related to non-ICM. They tested this by selecting OCM subjects that they felt best represented ICM, non-ICM, and instances of conflict and using chi-square tests to show how often these subjects co-occurred. They subsequently split up the "conflict" variable into four forms of conflict in order to show whether any of these forms might be more frequently found associated with ICM or non-ICM subjects. The results showed that conflict subjects were more likely to co-occur with non-ICM subjects, and that sociocultural/interpersonal conflicts were more likely to be associated with ICM subjects, whereas political conflicts were more likely to be associated with non-ICM subjects.

This article is a quantitative analysis of 592 participants from 8 societies. The study examines a number of theories about what predicts moralistic religions, including life history theory. Findings suggest that there is no evident relationship between these life history predictions and the religious beliefs regarding moralism.

The authors investigate the relationship between linguistic diversity and various environmental and spatial variables associated with biodiversity. Most of these variables predict linguistic diversity variably across different continents, and more so within Africa and extended Asia (Asia, the Pacific, and Australia) than within Europe and the Americas. This divide is theorized to be a result of differences in demography and impact of colonialism between the two global regions. However, two environmental factors, landscape roughness and density of river systems, are found to be significant predictors across all global regions. The authors suggest that, as in processes of speciation, rough terrain and watercourses both create physical barriers between which languages can develop in isolation while, in the case of river junctions, also providing transportation routes whereby hybrid languages can occasionally manifest.
