Abstract

Political polarization characterized by increasing ideological divergence and deepening affective hostility between partisan groups has become a defining challenge for contemporary democratic governance. The expansion of digital media platforms such as Facebook, X (formerly Twitter), YouTube, and WhatsApp has fundamentally reconfigured how individuals obtain information, articulate political preferences, and engage in public discourse. While these platforms broaden avenues for civic expression, they also facilitate ideological segmentation and undermine trust in institutions. This paper investigates the interaction between digital media environments, psychological predispositions, and political structures in shaping polarization. It reviews scholarly debates regarding whether digital platforms generate polarization or primarily intensify existing divisions and evaluates potential regulatory, educational, and design-based interventions. Drawing on empirical research and theoretical perspectives, the study argues for transparent platform governance, enhanced media literacy, and responsible algorithmic design to support healthier democratic communication online.
