Early Adolescents Demonstrate Peer-Network Homophily in Political Attitudes and Values

Research on political homophily has almost exclusively focused on adults, and little is known about whether political homophily is present early in life when political attitudes are forming and friendship networks are rapidly changing. We examined political homophily using a social network approach with rural middle school students (N = 213; mean age = 12.5 years; 57% female) from a remote U.S. community. Preregistered analyses indicated that early adolescents were more likely to spend time with people who shared similar political attitudes and values. These effects were most consistent for right-wing authoritarianism, patriotism, and anti-immigration attitudes. Our results show that political homophily is evident at an early age when young people are forming their political beliefs and making decisions about their friendships, suggesting that peer political-attitude socialization may emerge early in life.
