Maestripieri et al. pit evolutionary psychology against social psychological and economic perspectives in a winner-take-all empirical battle. In doing so, they risk positioning evolutionary psychology as an antagonistic subdisciplinary enterprise. We worry that such a framing may exacerbate tensions between "competing" scientific perspectives and limit evolutionary psychology's potential to serve as a unifying core theory.

Maestripieri et al. provide an important service in highlighting prosocial biases toward attractive people from a cross-disciplinary perspective. Here I comment on the conceptual and critical side of their review of evolutionary psychology studies. I propose that further work should be focused on understanding the role of signaling in prosocial behavior.

Mating motives lead decision makers to favor attractive people, but this favoritism is not sufficient to create a beauty premium in competitive settings. Further, economic approaches to discrimination, when correctly characterized, could neatly accommodate the experimental and field evidence of a beauty premium. Connecting labor economics and evolutionary psychology is laudable, but mating motives do not explain the beauty premium.

Drawing on multiple theoretical perspectives (e.g., social comparison theory, reward theory, evolutionary theory), the present research examined the relations of self and friendship network weight status to body satisfaction, self-esteem, and depression. A diverse, population-based sample of adolescents completed measures of well-being and were measured for height and weight. Boys had greater self-esteem if their male friendship networks' weight status mismatched, versus matched, their own weight status (d = ...

Personality similarity between parent and offspring has been suggested to play an important role in offspring's development of externalizing problems. Nonetheless, much remains unknown regarding the nature of this association. This study aimed to investigate the effects of parent-offspring similarity at different levels of personality traits, comparing expectations based on evolutionary and goodness-of-fit perspectives. Two waves of data from the TRAILS study (N = 1587, 53% girls) were used to study parent-offspring similarity at different levels of personality traits at age 16 predicting externalizing problems at age 19...

Ingmar Persson, Julian Savulescu
We have argued for an urgent need for moral bioenhancement; that human moral psychology is limited in its ability to address current existential threats due to the evolutionary function of morality to maximize cooperation in small groups. We address here Powell and Buchanan's novel objection that there is an 'inclusivist anomaly': humans have the capacity to care beyond in-groups. They propose that 'exclusivist' (group-based) morality is sensitive to environmental cues that historically indicated out-group threat...

Willingness to lay down one's life for a group of non-kin, well documented historically and ethnographically, represents an evolutionary puzzle. Building on research in social psychology, we develop a mathematical model showing how conditioning cooperation on previous shared experience can allow individually costly pro-group behavior to evolve. The model generates a series of predictions that we then test empirically in a range of special sample populations (including military veterans, college fraternity/sorority members, football fans, martial arts practitioners, and twins)...

Prosocial behavior is versatile, multifaceted, and complex. This special section seeks to advance coherent, integrative understanding of prosocial development by addressing this topic through the prism of motivations. This conceptual Introduction presents key ideas that provide a framework for thinking about motivation for prosocial behavior and its development. It outlines the evolutionary roots of prosocial behavior, underscoring the interdependent roles of nature and nurture. This is followed by a discussion of several key psychological mechanisms reflecting different motivations for prosocial action (empathy for a distressed other, concern about another's goal, desire to act in accordance with internalized prosocial norms, and guilt)...

Theoretical perspectives on mating differentially emphasize whether (and why) romantic partner selection and maintenance processes derive from stable features of individuals (e.g., mate value, mate preferences, relationship aptitude) and their environments (e.g., social homogamy) rather than adventitious, dyad-specific, or unpredictable factors. The current article advances our understanding of this issue by assessing how people's actual romantic partners vary on constructs commonly assessed in evolutionary psychology (Study 1), sociology (Study 2), and close relationships (Study 3)...

Using a recently created preemptive strike game (PSG) with 176 participants, we investigated if the motivations of spite and/or fear promotes aggression that requires a small cost to the aggressor and imposes a larger cost on the opponent, and confirmed the earlier finding that fear does but spite does not promote intergroup aggression when the groups are characterized as minimal groups; additionally, the rate of intergroup aggression did not vary according to the group membership of the opponent. The PSG represents a situation in which both the motivations of spite and of fear can logically drive players to choose an option of aggression against an opponent...

Major depression is a debilitating condition characterised by diverse neurocognitive and behavioural deficits. Nevertheless, our species-typical capacity for depressed mood implies that it serves an adaptive function. Here we apply an interdisciplinary theory of brain function to explain depressed mood and its clinical manifestations. Combining insights from the free-energy principle (FEP) with evolutionary theorising in psychology, we argue that depression reflects an adaptive response to perceived threats of aversive social outcomes (e...

Life history theory (LHT) is a powerful evolutionary framework for understanding physiological, psychological, and behavioral variation both between and within species. Researchers and theorists are increasingly integrating LHT into evolutionary psychology, as it provides a strong foundation for research across many topical areas. Human life history variation has been represented in psychological and behavioral research in several ways, including indicators of conditions in the developmental environment, indicators of conditions in the current environment, and indicators of maturation and life milestones (e...

Gossip is a pervasive social behavior. Its evolutionary survival seems related to its social functions, such as establishing group rules, punishing trespassers, exercising social influence through reputational systems, and developing and strengthening social bonds. We aimed at evaluating the effect of gossip on hormones (oxytocin and cortisol) and at identifying potential mediators of hormonal response to gossip. Twenty-two female students were randomly assigned to a gossip conversation or to an emotional non-gossip conversation...

BACKGROUND: Attachment has been implicated in the development of social anxiety. Our aim was to synthesise the extant literature exploring the role of adult attachment in these disorders. METHOD: Search terms relating to social anxiety and attachment were entered into MEDLINE, PsycINFO and Web of Science. Risk of bias of included studies was assessed using and adapted version of the Agency for Healthcare Research and Quality assessment tool. Eligible studies employed validated social anxiety and attachment assessments in adult clinical and analogue samples...

The comparative and evolutionary analysis of social learning and all manner of cultural processes has become a flourishing field. Applying the 'comparative method' to such phenomena allows us to exploit the good fortunate we have in being able to study them in satisfying detail in our living primate relatives, using the results to reconstruct the cultural cognition of the ancestral forms we share with these species. Here I offer an overview of principal discoveries in recent years, organized through a developing scheme that targets three main dimensions of culture: the patterning of culturally transmitted traditions in time and space; the underlying social learning processes; and the particular behavioral and psychological contents of cultures...

Humans exhibit extensive large-scale cooperation, of a form unprecedented in the natural world. Here I suggest that this cooperation arises in our species alone because of our uniquely potent capacities for social learning, imitation and teaching, combined with the co-evolutionary feedbacks that these capabilities have generated on the human mind. Culture took human populations down evolutionary pathways not available to non-cultural species, either by creating conditions that promoted established cooperative mechanisms, such as indirect reciprocity and mutualism, or by generating novel cooperative mechanisms not seen in other taxa, such as cultural group selection...

In humans and other animals, the individuals' ability to adapt efficiently and effectively to the niches they have actively contributed to construct relies heavily on an evolved psychology which has been shaped by biological, social, and cultural processes over evolutionary time. As expected, although many of the behavioral and cognitive components of this evolved psychology are widely shared across species, many others are species-unique. Although many animal species are known to acquire group-specific traditions (or cultures) via social learning, human culture is unique in terms of its contents and characteristics (observable and unobservable products, cumulative effects, norm conformity, and norm enforcement) and of its cognitive underpinnings (imitation, instructed teaching, and language)...

Plants pollinated by hummingbirds or bats produce dilute nectars even though these animals prefer more concentrated sugar solutions. This mismatch is an unsolved evolutionary paradox. Here we show that lower quality, or more dilute, nectars evolve when the strength of preferring larger quantities or higher qualities of nectar diminishes as magnitudes of the physical stimuli increase. In a virtual evolution experiment conducted in the tropical rainforest, bats visited computer-automated flowers with simulated genomes that evolved relatively dilute nectars...

Facial markers of body composition are frequently studied in evolutionary psychology and are important in computational and forensic face recognition. We assessed the association of body mass index (BMI) and waist-to-hip ratio (WHR) with facial shape and texture (color pattern) in a sample of young Middle European women by a combination of geometric morphometrics and image analysis. Faces of women with high BMI had a wider and rounder facial outline relative to the size of the eyes and lips, and relatively lower eyebrows...
