New research published in Evolutionary Psychological Science proposes a proactive model where envy, with its capacity to intensify scrutiny of social disparities and drive competitive neutralization, forms the core of radicalizing behaviors. From 2012 to 2016, about 4,000 citizens from diverse European Union cities made the choice to join militant factions in Syria. This decision, despite inherent risks, challenges traditional understandings of collective action theory, which posits that individuals might prefer benefiting from the actions of others without direct participation. Traditional ra...

In a new analysis published in Evolution and Human Behavior, a group of researchers have scrutinized the findings of a widely-publicized study by Anderson and colleagues, which had claimed significant female participation in hunting across diverse foraging societies. The reassessment reveals that while the original findings spurred important discussions, they likely overstate women’s involvement in hunting due to methodological shortcomings. In 2023, Anderson and colleagues published a study titled “The Myth of Man the Hunter: Women’s contribution to the hunt across ethnographic contexts” in w...

Recent research published in the journal Evolution and Human Behavior has highlighted an intriguing facet of family dynamics: girls are just as likely as boys to engage in physical and verbal aggression towards their siblings. The study, which examined into minor forms of violence like hitting, kicking, and yelling, reveals that such behaviors are surprisingly common among siblings and do not exhibit the gender differences typically seen in aggressive interactions outside the family. The primary aim of the new study was to explore the nature of sibling aggression and to determine whether the w...

A study on friendship preferences discovered that men showed a higher preference for friendships with other men who had different mate preferences, i.e., who were attracted to different types of women. The research was published in the Journal of Social and Personal Relationships. Friendship is one of the most universal and fundamental human relationships, observed across all cultures and ages. The origins of friendship can be traced back to the earliest human societies, where forming bonds with others was crucial for survival. It enabled cooperation in hunting, gathering, and protection from ...

An analysis of selfies shared publicly on Twitter and Instagram found that women living in environments with higher equal inequality and where people are preoccupied with their relative social standing are more likely to publish sexy self-photos. These areas also had higher sales of goods and services related to female physical appearance enhancement. The research was published in The Proceedings of the National Academy of Sciences (PNAS). Cultural sexualization of women refers to the process in which women’s bodies and identities are treated primarily as objects of sexual desire through cultu...

In a recent study, a team of scientists investigated how perceived facial dominance, indicated by the facial width-to-height ratio (fWHR), affected student evaluations of teaching. Their study found that higher fWHR enhanced evaluations for male professors but appeared to detrimentally affect female professors’ scores. The findings, published in Economics & Human Biology provide evidence for a gender-based double standard in academia that punishes women more harshly for perceived dominance. The fWHR is calculated by dividing the width of the face by its height, and studies have suggested that ...

New research conducted in the United Kingdom found that multi-partner relationships are generally less desirable than singleness and monogamy. However, the study found that men are six times more likely than women to be open to polygynous relationships, which involve one man with multiple female partners. Among the least desired relationship types was two-timing, where one person has two partners who are unaware of each other. The paper was published in Archives of Sexual Behavior. Polygamy is a marriage practice where an individual has more than one spouse simultaneously. This practice can ma...

What makes a person beautiful has fascinated artists and scientists for centuries. Beauty is not, as it is often assumed to be, “in the eye of the beholder” – but follows certain predictable rules. Symmetry and proportions play a role, and though culture and norms shape our perception of beauty, researchers observe a consistently striking agreement among people on whom they regard as beautiful. Not surprisingly the beauty market has been on a steady rise (besides a minor 2020 Covid slump), reaching $430 billion in revenue in 2023, according to a recent McKinsey report. The fascination for the ...

New research, published in the journal Evolutionary Psychology, provides evidence that biracial people are viewed more positively than their monoracial counterparts, potentially due to the historical and genetic implications of their ancestry. This study conducted in both the United States and China found that biracial individuals were perceived as more attractive, trustworthy, intelligent, and likely to be successful than others, challenging existing notions of racial bias and favoritism. The motivation behind this study stems from a growing interest in interracial relationships and their soc...

In a world that often emphasizes superficial qualities, a recent study has unveiled a refreshing perspective on human relationships and preferences. Researchers have found that, regardless of sexual orientation, individuals prioritize intelligence and kindness over physical attractiveness, health, or socioeconomic status when choosing a partner. This study, conducted in Brazil and published in the Archives of Sexual Behavior, not only sheds light on the universal nature of these preferences but also highlights the subtle nuances that sexual orientation and gender bring to the dynamics of partn...
