In the current research, we explored preferences for men’s beardedness among Iranian and Hispanic women and whether those preferences were moderated by trait pathogen proneness. In Study 1, Hispanic women were recruited and asked to choose the beard profile, from clean-shaven to very long, on a variety of traits (i.e., attractiveness, masculinity, fighting ability, reliable partner, and suitable father). Women more frequently chose light and moderate-length beard types across all outcome measures, and their self-reported levels of disgust was associated with higher preferences for clean-shaven profiles. In Study 2, Hispanic and Iranian women were recruited and asked to rate the beard profiles across the measures. Compared to Iranian women, Hispanic women demonstrated a stronger preference for bearded men. Further, there were cultural differences in self-reported measures of disgust and their preferences for beards in men.

They attribute their lack of success to genetic factors, evolved mate preferences, and social inequities. While we have a deep ancestral history of incels, the modern incel community is an evolutionarily novel group that fosters a shared victimhood identity. We applaud Lindner for an important contribution to the scant literature on incels and highlight the importance of her evolutionary psychological lens in understanding their grievances. Our critique of Lindner’s work addresses two key issues. Firstly, we challenge the hypothesis that incels engage in simulated coalitional bargaining for sexual access. While coalitional bargaining for sexual access may have played a role in ancestral populations of involuntarily celibate men, this is not a suitable analysis of modern incels. Instead, the incel community operates as a fatalistic echo-chamber, where failure is celebrated, and individuals discourage each other from pursuing romantic success. Secondly, we critique the association between incels and violence. Contrary to common beliefs, empirical evidence suggests that incels are not particularly prone to violence. Incels’ propensity for violence appears relatively low compared to that of the general population. We conclude by offering one hypothesis as to why modern day incels are not as violent as we might expect. The Male Sedation Hypothesis, that online virtual worlds, such as pornography, may pacify the potential for violence among sexless young men, providing a counterfeit sense of sexual fulfillment and reducing motivation for real-life mate competition.</p></div>","PeriodicalId":7178,"journal":{"name":"Adaptive Human Behavior and Physiology","volume":"9 3","pages":"252 - 259"},"PeriodicalIF":1.6,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41841861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
