Are facial width-to-height ratio, 2D:4D digit ratio and skeletal muscle mass related to men dominant behavior in the Chicken Game?

Does the primate face cue personality?

“…This was supported by multiple human studies linking male facial width, typically measured as facial width-to-height ratio (fWHR, Fig. 1a) (Weston et al, 2007), to dominance (mostly self-reported or inferred, but also estimated from military rank and economic game outcomes) (Geniole, Denson, Dixson, Carré, & McCormick, 2015; Polo et al, 2022) and aggression (Goetz et al, 2013; Haselhuhn, Ormiston, & Wong, 2015; Stirrat et al, 2012; Třebický, Havlíček, Roberts, Little, & Kleisner, 2013; Wen & Zheng, 2020; Zilioli et al, 2015). Wider faces are also perceived as more dominant (Alrajih & Ward, 2014; Lefevre & Lewis, 2014; Mileva, Cowan, Cobey, Knowles, & Little, 2014), acting as cues or even signals of individual dominant/aggressive personality traits.…”
