In one study, almost 9 in 10 young people questioning their gender seemed to be subject to social influence

86.7% of the young people in Lisa Littman’s 2018 study1 belonged to a friend group where one or more friends came out as trans at the same time, and/or had an increase in their use of social media.

Social contagion – the involuntary “catching” of behaviors and attitudes across connected individuals2 – is a well-accepted phenomenon in psychological literature3. It is well-documented that adolescents — and females in particular — are prone to social contagion effects, from cutting4 to eating disorders5. Social network analyses suggest that peer contagion underlies the influence of friendship on obesity, unhealthy body images, and expectations6.
