The cheerleader effect is a phenomenon in which people tend to appear more attractive when they are in a group rather than when they are viewed individually. This effect is thought to occur because people tend to focus on the group as a whole rather than on each individual person. This leads to a perception that the group is more attractive than its individual members.
The term "cheerleader effect" was coined by the character Barney Stinson in the television show "How I Met Your Mother," but the concept has been studied in psychology. A study by Walker and Vul (2013) found that people tend to rate faces as more attractive when they are presented in a group rather than alone. The authors suggest that this effect may be due to a cognitive mechanism that simplifies the visual processing of groups of people.
