Women more interested in short-term relationships prefer men with good genes. We ran four controlled experiments with heterosexual women, based on the idea that conspicuous consumption manifestations signal good genes, to test whether a conspicuous object could increase the attractiveness and desire for an uncommitted relationship with a man. We also tested the interaction between car type (non-conspicuous and conspicuous) and reproductive strategy in the judgment of attractiveness and desire for an uncommitted relationship. Contrary to previous studies, the results of our experiments rejected the hypothesis of conspicuous consumption as an enhancer of attractiveness. None of our studies showed an interaction between car type and sociosexuality. In Study 3, the non-conspicuous car's man was considered more attractive. This effect disappeared after controlling social desirability in Study 4. Perhaps the positive publication bias explains the unprecedented nature of our results. Another possible explanation remains in some cultural influence. Maybe, Brazilian women with a high education level (our participants) are not susceptible to conspicuous consumption as an indicator of good genes. We also want to emphasize that, although other studies have corroborated our hypotheses using similar experiments, the present study was the only one that controlled social desirability and socioeconomic status.

Organisms benefit from choosing partners who are willing and able to provide them with benefits (e.g., choose based on warmth, competence, wealth). But which should they prefer in a partner – willingness or abilities? We tested the hypothesis that people will focus on whichever trait is more variable in others: the more variance there is in a trait, the greater the difference there is between the “best” and “worst”, so the more that trait will impact the chooser (all else equal). In two studies, participants saw a range of partners for a hypothetical money distribution task who either varied more in the amount of money they had to distribute (Unequal Wealth condition) or in the percent of their money they gave away (Unequal Generosity condition). Participants had a default preference to know about others' generosity rather than their wealth; this preference was strengthened when others varied more in generosity and weakened when others varied more in wealth. Thus, our study shows that people are sensitive to the amount of population variance on a trait, and flexibly adjust their partner preferences to focus on traits which vary more among others.

Among other things, love can refer to care for a child or to sexual desire. This curious linguistic association probably reflects the evolutionary repurposing of machinery that established and maintained the ancient bond between mothers and offspring for the establishment and maintenance of romantic bonds between sexual partners. Oxytocin has been implicated in both kinds of bond. I propose that oxytocin possessed an ancestral function in gamete release and that the earliest form of attachment to offspring was a suppression of appetite after spawning to prevent parents from eating their progeny. Maternal care has been greatly elaborated since this simple beginning. Human infants elicit feelings of care because of their helplessness which has been ascribed to their neural immaturity at birth which has, in turn, been ascribed to problems associated with the delivery of a large-brained infant through a narrow birth-canal. I propose instead that the helplessness and hairlessness of human infants were adaptations of ancestral infants to obtain better care by being held close to warm maternal bodies.

Motivations to avoid infectious disease seem to influence prejudice toward some groups, including groups not explicitly associated with infectious disease. The standard explanation for this phenomenon is based on signal detection theory and proposes that some prejudices partially arise from pathogen detection mechanisms that are biased toward making false alarms (false positives) in order to minimize misses (false negatives). Therefore, pathogen detection mechanisms arguably categorize a broad array of atypical features as indicative of infection, which gives rise to negative affect toward people with atypical features. We tested a key hypothesis derived from this explanation: specific appearance-based prejudices are associated with tendencies to make false alarms when estimating the presence of infectious disease. While this hypothesis is implicit in much work on the behavioral immune system and prejudice, direct tests of it are lacking and existing relevant work contains important limitations. To test the hypothesis, we conducted a cross-sectional study using a large U.S. sample (N = 1450). Using signal detection theory methods, we assessed tendencies to make false alarms when identifying infection threats. We further assessed prejudice toward multiple relevant social groups/categories. Results showed weak evidence for the key hypothesis: for only one of four tested target groups were tendencies to make false alarms in sickness detection significantly associated with prejudice. However, this relation was not significant when controlling for a potential confound. These results cast doubt on the notion that individual differences in appearance-based prejudices arise from individual differences in tendencies to make false alarms in assessing pathogen threats.
