Ethnic groups are universal and unique to human societies. Such groups sometimes have norms of behavior that are adaptively linked to their social and ecological circumstances, and ethnic boundaries may function to protect that variation from erosion by interethnic interaction. However, such interaction is often frequent and voluntary, suggesting that individuals may be able to strategically re...

The need to effectively communicate HIV/AIDS messages in South Africa, given the high prevalence of the pandemic, cannot be overemphasised. Communication scholars have long emphasised the need to recognise adherence to cultural norms of target communities as catalyst for effective HIV/AIDS communication. Unfortunately this call has not been totally heeded by the designers of HIV/AIDS communicat...

MOST MODERN PEOPLE think it is obvious why people become modern. For them, a more interesting and important puzzle is why some people fail to embrace modern ideas. Why do people in traditional societies often seem unable or unwilling to aspire to a better life for themselves and their children? Why do they fail to see the benefi ts of education, equal rights, democracy, and a rational approach ...

Humans in many societies cooperate in economic experiments at much higher levels than would be expected if their goal was maximizing economic returns even when interactions are anonymous and one-shot. This is a puzzle because paying a cost to benefit another player in one-shot interactions has no direct benefit to the cooperator. This paper explores the logic of two competing evolutionary hypot...

In The Descent of Man, and Selection in Relation to Sex, published in 1871, Charles Darwin wrote: "I fully ... subscribe to the judgment of those writers who maintain that of all the differences between man and the lower animals the moral sense or conscience is by far the most important." I raise the question of whether morality is biologically or culturally determined. The question of whether ...

Human cooperation is highly unusual. We live in large groups composed mostly of non-relatives. Evolutionists have proposed a number of explanations for this pattern, including cultural group selection and extensions of more general processes such as reciprocity, kin selection, and multi-level selection acting on genes. Evolutionary processes are consilient; they affect several different empiric...

Does local context (e.g., city of residence) matter for self and well-being? We theorized that it does because local contexts diverge in prevalent historically-derived ideas, norms, and products. Through historical analysis, studies of norms (tightness-looseness; Study 1) and cultural products (content analyses of newspaper headlines, venture capital firm websites, hospital websites; Studies 2-...

Cultural transmission of information plays a central role in shaping human knowledge. Some of the most complex knowledge that people acquire, such as languages or cultural norms, can only be learned from other people, who themselves learned from previous generations. The prevalence of this process of "iterated learning" as a mode of cultural transmission raises the question of how it affects th...

INTRODUCTION Interpersonal contacts have been identified as performing an important role in supply chain management, especially where the cultural concept of informal relationships has a major influence on both social and business norms. Perhaps the most studied type of informal relationship is guanxi, which derives from Chinese social-cultural norms and influences human behaviour in society. E...

Building online trust and understanding its relationship to online consumer behavior are important topics for e-commerce designers and human-computer interaction researchers. In this paper, the relationships between multidimensions of online trust (integrity, benevolence, and ability) and purchase intention are tested and discussed. Furthermore, the uncertainty avoidance cultural orientation, s...
