“…Research has shown that social hierarchy is linked to personality traits in both animals and humans ( Colléter and Brown, 2011 ; David et al, 2011 ; Dasgupta et al, 2022 ; Vékony et al, 2022 ). For example, dominant individuals tend to be more assertive, confident, and proactive ( Blanchard et al, 1988 ; Salonen et al, 2022 ), while submissive individuals are often more anxious, passive, and reactive ( Catarino et al, 2014 ; Zaffar and Arshad, 2020 ). In addition, social hierarchy can shape individual behavior and physiology ( Schmid Mast, 2010 ; Flota-Bañuelos et al, 2019 ) including stress responses ( Knight and Mehta, 2017 ; Karamihalev et al, 2020 ), brain activity ( Breton et al, 2014 ; Williamson et al, 2019a ), and gene expression ( Pohorecky et al, 2004 ; Horii et al, 2017 ; Lea et al, 2018 ; Williamson et al, 2019b ).…”
