This research applied social domain theory to illuminate reasoning about the perceived legitimacy and limits of group decision making (majority rule) among adolescents from urban and rural China (N = 160). Study 1 revealed that adolescents from both urban and rural China judged group decision making as acceptable for both social conventional and prudential issues, but not for personal issues or those that entailed possible harmful coercion of others. Study 2 revealed that personal jurisdiction develops later for rural than urban adolescents for certain issues (democratic rights to political participation and choice of friends). Results indicate that reasoning about group and personal jurisdiction in a non-Western society (China) is influenced by social domain, age, and environmental setting (modern vs. traditional).
