Abstract Evolutionary social scientists have argued that impulsive behavior is adaptive in harsh and unpredictable conditions. Is this true? This paper presents a mathematical model that computes the optimal level of impulsivity in environments varying in harshness and unpredictability. We focus on information impulsivity, or choosing to act without gathering or considering information about the consequences of one's actions. We explore two notions of harshness: the mean level of resources (e.g....

Abstract An overall evaluation of potential relationship partners (mate value) is fundamental to numerous key lifetime decisions, but how people integrate the diverse component traits of mate value remains poorly understood. Three within-subjects studies (N = 190) contrast multiple models of mate value trait integration, including both compensatory and non-compensatory decision-making strategies. A weighted additive model outperformed equal weight and take-the-best strategies (Study 1), as well ...

Abstract During evolution, humans faced the trade-off between preferences for feminine and masculine traits which are connected to parental care, and genetic quality or provisioning abilities, respectively. Recent research has shown that environmental factors influence preferences for femininity/masculinity in potential mates. However, studies mainly focus on women's preferences for isolated cues in men. We examined the influence of pathogen and resource threat on women's and men's preference fo...

Abstract Moral elevation is a positive social emotion, which is triggered by observing third parties behaving benevolently, and which in turn triggers a motivation to behave benevolently towards others in general. It has been suggested that this relatively obscure emotion may be the output of a naturally selected cognitive adaptation which functions to help us retain our position in the competition for access to beneficial social relationships. This suggestion is here interpreted within the fram...

Abstract Among non-human animals, a key strategy to resolve conflicts without fighting relies on assessing relative fighting ability on the basis of physical cues such as size and strength. Recent studies hypothesize that the human mind also contains mechanisms for spontaneously coordinating conflict behavior on the basis of difference in physical strength, even if strength is not rationally relevant to the conflict. We provide the first direct, experimental test of the existence of such mechani...

Abstract There are two broad functional explanations for second-party punishment: fitness-leveling and deterrence. The former suggests that people punish to reduce fitness differences, while the latter suggests that people punish in order to reciprocate losses and deter others from inflicting losses on them in the future. We explore the relative roles of these motivations using a pre-registered, two-player experiment with 2426 US participants from Amazon Mechanical Turk. Participants played as t...

Abstract The evolutionary social sciences (ESSs) are thriving, and seem to have entered a period of normal science. This is a good time to examine our own practices, theoretical and empirical, and to ask how we might improve. Here I review papers published in the past five years in EHB to explore major trends in the field. Theoretically, the popularity of certain topics (cooperation, mating, life history) has led to great progress, but might have narrowed our theoretical vision. Empirically, mos...

Abstract Researchers have suggested that more attractive women will show stronger preferences for masculine men because such women are better placed to offset the potential costs of choosing a masculine mate. However, evidence for correlations between measures of women's own attractiveness and preferences for masculine men is mixed. Moreover, the samples used to test this hypothesis are typically relatively small. Consequently, we conducted two large-scale studies that investigated possible asso...

Abstract The idea that individual differences in behavior and physiology can be partly understood by linking them to a fast-slow continuum of life history strategies has become popular in the evolutionary behavioral sciences. I refer to this approach as the “fast-slow paradigm” of individual differences. The paradigm has generated a substantial amount of research, but has also come increasingly under scrutiny for theoretical, empirical, and methodological reasons. I start by reviewing the basic ...
