The beliefs held about adolescence and what is normal for adolescents can profoundly affect adolescents' development.

Beliefs held about adolescence can shape how adults interact with and treat adolescents, which can impact their development. For example, if adults believe that all adolescents are rebellious and untrustworthy, they may be less likely to give them opportunities for responsibility and independence, which are important for building self-esteem and competence. On the other hand, if adults believe that adolescents are capable of making responsible decisions and contributing to society, they may be more likely to involve them in decision-making and leadership roles, which can facilitate positive development.
