Contextual Factors that Heighten Interest in Coalitional Alliances with Men Possessing Formidable Facial Structures

Individuals use facial width-to-height ratio (fWHR) to infer dominance and fighting ability of others. We hypothesized that broad assessments of target formidability from fWHR would form a basis for determining men’s coalitional value, with high-fWHR men being especially valuable in roles requiring physical strength. Across five studies (N=1,445), we identified the social affordance of male facial structures connoting formidability and how judgments influence coalitional decisions. In addition to replicating previous findings indicating high-fWHR men are more desirable for tasks requiring physical strength, we found that such men are aversive for tasks requiring creativity (Studies 1 and 2). High-fWHR men were additionally perceived as more effective in combat roles in the military (Study 3). Finally, in two pre-registered studies, we found that activation of competitive motivations heightens individuals’ interest in formidable allies during intergroup interactions (Study 4), but not interest in approaching them (Study 5). We interpret findings using evolutionary and social affordance theories and discuss hypothesized ancestral origins of selecting formidable allies.

An Alternative Account of Anti-Effeminacy Bias: Reputation Concerns and Lack of Coalitional Value Explain Honor-Oriented Men’s Reluctance to Befriend Feminine Men

Anti-effeminacy bias follows a specific pattern with men showing stronger anti-effeminacy bias against male targets than women. Previous explanations focused on men’s higher tendency to stigmatize feminine men as homosexual and motives to maintain a dominant group status. Here, we suggest that certain expressions of anti-effeminacy bias may rather be a manifestation of men’s reputation management motives for coalition formation, and be amplified among high (vs. low) masculine honor-oriented men. In three studies with samples from the United Kingdom and Turkey, we showed that men perceived feminine (vs. masculine) male targets as lower on coalitional value and were more reluctant to befriend them, yet this applied only to high (not low) honor-oriented men. Honor-oriented men’s friendship reluctance was mediated by concern with losing reputation by association with targets lacking coalitional value. These findings extend understanding of anti-effeminacy bias by drawing attention to men’s reputation concerns for coalitional reasons and individual differences.
