The social science literature abounds with examples of human tribalism, the tendency to categorize individuals on the basis of their group membership and treat in‐group members benevolently and out‐group members malevolently. I argue that this tribal inclination is an evolved response to the threat of intergroup violence and warfare that was endemic in ancestral human environments (and is still common today). Here I hypothesize that intergroup conflict has profoundly affected the social… 
Evolution and the psychology of intergroup conflict: the male warrior hypothesis
How male coalitional aggression could have affected the social psychologies of men and women differently is described and preliminary evidence from experimental social psychological studies testing various predictions from the ‘male warrior’ hypothesis is presented.
Genocide and the Male Warrior Psychology
This chapter outlines how sexual selection may have prompted the evolution of psychological mechanisms that facilitate intergroup violence, particularly among men, and emphasizes how these psychological mechanisms may interact with features of the authors' modern environment, such as social, cultural, and political factors, to produce genocide.
Some remarks about murder: a Darwinian perspective
Paleoanthropological remains and historical data show that human beings have a long history of violent aggression. However, killing in group is distinct from killing in a one-to-one interaction, as
Strangers With Benefits
Working from an evolutionary framework, a unique pattern of outgroup attraction is identified, such that attraction to outgroup men increases as fertility increases across the cycle in naturally cycling women.
Intergroup Biases in Fear-induced Aggression
The finding that only intragroup cooperation but not intergroup aggression emerged in the minimal group experiments strongly suggests that inter group aggression involves a psychological mechanism that is independent from that of intragroups cooperation.

It is argued that the authors' evolved coalitional psychology may contain a set of distinct evolved heuristics designed specifically for offensive and defensive coalitional aggression.
Men’s Interest in Allying with a Previous Combatant for Future Group Combat
The findings suggest that men attend to the benefits of allying with a man who has demonstrated relatively superior fighting ability, and alliance with a previous opponent for group combat may vary with the relationship value of the opponent and the utility of demonstrating cooperativeness to third-party observers.
Pandemic Leadership: Sex Differences and Their Evolutionary–Developmental Origins
This review article contextualizes sex differences in pandemic leadership in an evolutionary framework and indicates that against the invisible viral foe that can bring nations to their knees, the strategic circumspection of empathic feminine health “worriers” may bring more effective and humanitarian outcomes than the devil-may-care incaution of masculine risk-taking “warriors”.
Peacemakers or Iron Ladies? A Cross-National Study of Gender and International Conflict
Abstract Conventional wisdom suggests that when women attain high political office they are more likely to act as peacemakers than their male counterparts. In contrast, this article argues that women


Intergroup prejudices and intergroup conflicts.
Group stereotypes. Ethnic prejudices. Wars. These are substantial social problems, and they attract the attention of many social scientists, including psychologists who study social cognition and
Collective Violence: Comparisons between Youths and Chimpanzees
The similarities in aggression between humans and chimpanzees are viewed as being adaptive responses to local conditions, predicated on an inherent male concern for social status, which suggests that the use of physical violence to resolve individual status competition is an important predictor of collective violence at the gang level.
Life Histories, Blood Revenge, and Warfare in a Tribal Population
A theory of tribalviolence is presented showing how homicide, revenge, kinship obligations, and warfare are linked and why reproductive variables must be included in explanations of tribal violence and warfare.
Running Head: The Altruism Puzzle Psychological Adaptations for Prosocial Behavior: The Altruism Puzzle
This chapter addresses the evolutionary roots of the, by and large, uniquely human capacity for helping other people who are not closely related. It is argued that prosocial tendencies have evolved
The origins of sex differences in human behavior: Evolved dispositions versus social roles
The present article contrasts these 2 origin theories of sex differences and illustrates the explanatory power of each to account for the overall differences between the mate selection preferences of men and women.
Demonic Males: Apes and the Origins of Human Violence
This study is an analysis of the roots of human savagery, dealing with the fundamental questions of why the majority of violence is perpetrated by men, whether this is a matter of nature or nurture
Evolutionary origins of stigmatization: the functions of social exclusion.
The authors propose that phenomena currently placed under the general rubric of stigma involve a set of distinct psychological systems designed by natural selection to solve specific problems associated with sociality.

Sexual access to females as a motivation for joining gangs: An evolutionary approach
It is argued that an understanding of the evolutionary psychology of sex and reproductive competition can account for the typical age and sex compositions of gangs and the role of sexual access to females in the motivation of males who join gangs.
Overconfidence in wargames: experimental evidence on expectations, aggression, gender and testosterone
In experimental wargames, overconfidence and attacks are more pronounced among males than females, and testosterone is related to expectations of success, but not within gender, so its influence on overconfidence cannot be distinguished from any other gender specific factor.
