“…Given the importance of attractiveness and the broad agreement on the facial traits that are perceived as attractive (Langlois et al, 2000), it is perhaps surprising that perceptions of facial attractiveness are not necessarily stable and can be influenced by the presence of other surrounding faces (Carragher et al, 2019(Carragher et al, , 2020Carragher, Lawrence, et al, 2018;Geiselman et al, 1984;van Osch et al, 2015;Walker & Vul, 2014;Ying et al, 2019). One such finding, dubbed the "cheerleader effect" (Walker & Vul, 2014; or "friend effect," Ying et al, 2019), refers to the observation that faces are rated as more attractive when seen in a group of other faces compared with when seen in isolation (Carragher et al, 2019;Carragher, Lawrence, et al, 2018;Walker & Vul, 2014).…”
