In this study, the author explores different pathways to the emergence of clothing outside of thermoregulation, with a focus on the use of clothing for disguise or concealment. He finds disguises in 8 out of 10 sampled societies, proposing that attempts at disguise or concealment is one possible pathway to the cultural evolution of clothing. He also finds clothing used for modesty and body armor purposes.

This study explores the ways in which human deception has evolved using a sample of 145 societies from eHRAF. After noticing that most research has focused just on tactical deception on humans, this study delved into the categorization and prevalence of human aggressive mimicry. The authors suggest that deception evolved from the context of directing it toward prey. The presence of human aggressive mimicry supports that this is a near-universal cross-cultural practice among hunter-gatherers and the authors highlight the importance of further research on human-nonhuman interactions. The authors posit that this hypothesis could serve as a link between the Social Brain Hypothesis and the Foraging Brain Hypothesis.

The article examines whether cultural groups tend to use supernatural beliefs more to explain natural phenomena or social phenomena. Analysis of ethnographic text from 114 diverse societies reveals that supernatural explanations are more common for natural phenomena, consistent with the theory that humans tend to perceive intent and agency in the natural world. However, supernatural explanations of social phenomena were more prevalent in urbanized societies with greater social complexity and anonymity. The study highlights how people use supernatural beliefs to explain their world and how this varies across small-scale and urbanized communities.

This study uses Bayesian phylogenetic regression modelling across 131 largely non-industrial societies to test how variation of punishment is impacted by social, economic, and political organization. The authors focus on the presence of norm violations and types of punishments, and explores their relationships. The norm violations include adultery, rape, religious violations, food violations, and war cowardice. While the types of punishment are reputational, material, physical, or education. This study suggests a hypothesis for each type of punishment in relation to socioecological variables.
