Teenagers now spend close to nine hours a day online—but this episode argues that time is the wrong question. Drawing on developmental, personality, and clinical psychology, we explore how identity is formed in a hybrid digital–offline world. From gaming and multiple social media profiles to popularity bias, algorithmic amplification, and peer influence, we examine how young people construct their life stories—and what happens when platforms begin shaping those narratives for them. The real risk isn’t screens themselves, but how agency, belonging, and coherence are distorted when algorithms quietly take the pen.
