Article
Humans are thought to have evolved in small, egalitarian hunter-gatherer societies. Evolutionary theories of leadership, which draw heavily on studies of contemporary hunter-gatherer and other small-scale societies, have proposed numerous traits that putatively characterize leaders in domains of sociality, productivity, reproduction, dominance, and...

This study tested four theoretical models of leadership with data from the ethnographic record. The first was a game-theoretical model of leadership in collective actions, in which followers prefer and reward a leader who monitors and sanctions free-riders as group size increases. The second was the dominance model, in which dominant leaders threat...
Article
Full-text available
Existing approaches within leadership studies often share a bias towards industrialized societies and lack broader cross-cultural and ethological reference. Meanwhile, cross-cultural and evolutionary approaches within anthropology are actively working to unify research on leadership and followership across the biological and social sciences. This r...
Article
Full-text available
Researchers argue that third parties help sustain human cooperation, yet how they contribute remains unclear, especially in small-scale, politically decentralized societies. Studying justice among Mentawai horticulturalists in Indonesia, we examined evidence for punishment and mediation by third parties. Across a sample of 444 transgressions we fin...

Researchers argue that third-party involvement is critical for sustaining human cooperation, yet how third parties contribute remains unclear, especially in small-scale, politically decentralized societies. In a study of wrongdoing and punishment among the Mentawai horticulturalists of Indonesia, we test two hypotheses of third-party involvement: p...
Article
Reputations are an essential feature of human sociality and the evolution of cooperation and group living. Much scholarship has focused on reputations, yet typically on a narrow range of domains (e.g. prosociality and aggressiveness), usually in isolation. Humans can develop reputations, however, from any collective information. We conducted explor...
Article
Full-text available
Conflicts are ubiquitous between individuals as well as between groups. Effective conflict resolution is essential for individual well-being and group functioning and often involves leadership dynamics. The evolutionary human sciences have suggested conflict resolution is shaped by psychological heuristics, norms, and ecology. There are limited emp...

Henrich (2020) discusses the role of Christianity in shaping Western psychology and affluence. We expand on his perspective by critically discussing Henrich's account of religions. Drawing on cross-cultural research, we clarify when religions are consistent with Henrich's account of religions, and when they reflect pragmatic specialists who assist...
Article
Many researchers have turned to evolutionary theory to better understand diversity in leadership. Evolutionary theories of leadership, in turn, draw on ethnographic cases of societies thought to more closely resemble the smaller-scale, face-to-face communities in which humans evolved. Currently, though, there is limited systematic data on the natur...

Long before the term Machiavellian Intelligence was coined, James Neel was pondering the role of ‘princes’ in the evolution of exceptional human intelligence. The two cornerstones of Neel’s theory – leaders’ superior skills, knowledge, and intelligence (at least as judged by others), and their greater reproductive success – have been amply confirme...
Article
Full-text available
The cross-cultural ethnographic literature has traditionally used the label male “homosexuality” to describe sexual relationships between biological males without considering whether or not the concept encompasses primary sexual attraction to adult males. Although male androphilia seems to be found in all national populations, its universal existen...
Chapter
Full-text available
Social learning among hunter-gatherers has been widely discussed in the literature and authors often draw on ethnographic cases to support theoretical models. In this study we report on the cross-cultural occurrence of various modes and processes of social learning in distinct cultural domains from the ethnographic record. To our knowledge this is...
Article
Suicide is responsible for more deaths than all wars and homicides combined. Despite over a century of research on this puzzling and tragic behavior, and a recent increase in the number of treatments and intervention programs, it remains a global scourge. There is abundant research on suicidality in Western populations, but research on suicide amon...
Article
Barthes, Godelle, and Raymond (2013, Evolution and Human Behavior, 34, 155–163) proposed a hypothesis to (1) identify the process by which genes influencing male homosexual preference (MHP) are passed on over evolutionary time, and (2) account for why life-course persistent MHP is restricted to humans. According to their hypothesis, certain genes l...
Thesis
Full-text available
Egalitarian societies have been the subject of significant academic attention for their unique cultural qualities, both as a representation of a distinct political category, and as a base line in the context of biological and cultural evolution. Although the domains and degrees of egalitarianism vary cross-culturally, certain characteristics seem u...
