Teenagers often place a high value on their peers' opinions because adolescence is a developmental stage marked by a strong desire for social acceptance and identity formation. Peer relationships become central during this period, and teens seek validation from their peers to fit in and establish their place in social hierarchies. They may perceive their peers as understanding their experiences better than their parents, leading to a preference for peer opinions. Additionally, teens may feel peer approval is more immediate and relevant to their daily lives compared to their parents' perspectives.
