Does a woman’s age predict her preferences for an ideal partner? Through a cross-cultural study of heterosexual women ages 18-67 from 147 countries, the authors of this article find that age has a negligible effect on a woman’s partner preferences in general. However, they do find some relationships between age and specific preferences, such as confidence-assertiveness, intention to be a parent, and the age range deemed acceptable for a partner.

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 study investigates responses to childlessness in a cross-cultural sample. Solutions to childlessness appear universal, and magico-religious-ethnomedical solutions seem the most likely to be tried first. Empirical analysis also shows that women are blamed for childlessness more often than men, which the authors suggest could be due to women’s lower status.

Authors investigate the prevalence of male homosexual preference (MHP) cross-culturally. They employ four models to test the link between level of social stratification and the probability of observing male homosexual preference (MHP). Authors believe that this link supports the hypergyny hypothesis, which proposes that increased social stratification allows for some sort of factor that improves functional female fertility, perhaps through marriage to men of higher social classes. This would thereby allow more access to resources and consequently the ability to support a greater number of more reproductively-successful offspring. Authors do not make a causal link, however; rather, social stratification may be associated with a yet-undetermined pleiotropic factor that is somehow positive despite its cost on functional male fertility.

The study aimed to explore the ideal-parent beliefs among mothers and fathers from 37 countries to determine whether the definition of an ideal parent varied across countries and social classes. Open-ended questions were used to gather data, and Leximancer Semantic Network Analysis was utilized to identify parenting culture zones and extract the predominant themes and concepts in each culture zone. The results revealed specific types of ideal-parent beliefs in five parenting culture zones, with subtle differences between the English-speaking, European Union, and Russian parents emphasizing "being caring," while French-speaking parents valued "listening" or being "present." Additionally, ideal-parent beliefs varied by education levels within culture zones, suggesting that social class differences should not be dismissed in parenting intervention research.

This article explores the following questions: What environmental and cultural factors might explain variation in prejudice across cultures? Do these factors explain the intention to vote for nationalist politicians? The authors perform seven studies, focusing on the link between cultural tightness and the rise of prejudice in cultures. They theorize that cultural tightness is positively correlated with the rise of prejudice against people perceived as disrupting the social order. From this theory, they suggest three hypotheses: 1) cultural variation in tightness is related to cultural variation in prejudice, 2) cultural tightness is related to the support for nationalist politicians, and 3) cultural tightness is a link between ecological threats and prejudice. The results support these hypotheses, offering a cultural evolutionary perspective on prejudice.
