Smartphones and social networking sites (SNSs) have become deeply embedded in everyday life, profoundly reshaping adolescents' social environments and behavioral patterns, with growing concerns about their mental and moral development. As outlined in Jonathan Haidt's recent work, the rise in adolescent mental health problems closely coincides with the expansion of the digital era since the early 2010s. Building on this body of research, the present project examines how excessive SNS use may negatively affect the moral capacities of adolescents and young adults.
Empirical evidence across disciplines indicates that increased SNS use is associated with higher levels of depression, anxiety, and antisocial behavior among youth. This project specifically explores whether problematic social media use threatens moral sensitivity, weakens engagement with moral dilemmas, and promotes moral disengagement. Additionally, exposure to violent or weapon-related content for entertainment purposes may hinder moral identity development by reducing sensitivity to harm and increasing aggressive tendencies.
Methodologically, the study integrates findings from psychology, sociology, and media studies to develop a conceptual model illustrating how SNS use may contribute to the erosion of moral standards and the escalation of aggressive behavior, both online and offline. By addressing gaps in current knowledge on digital influences during adolescence, the study aims to inform evidence-based interventions that promote healthier social media use and support robust moral development during critical periods of identity formation.
