A Review of Group Polarization Research from a Dynamics Perspective

The rapid rise of social media has accelerated the evolution of public opinion, leading to frequent group polarization. Meanwhile, advancements in information science have enabled large-scale experiments, positioning dynamics as a crucial perspective for studying group polarization. This paper systematically reviews group polarization from a dynamics perspective. First, we outline its definitions and its explanatory theories. Then, we examine the role of dynamics in polarization research, summarize the current measurement methods of group polarization, and analyze intervention strategies based on elements of dynamics. Finally, we propose a logical framework for dynamics-based interventions. Our findings indicate that while research on group polarization from a dynamics perspective is relatively comprehensive, most intervention studies remain at the simulation level, requiring further validation for real-world applicability. This review provides a systematic overview of group polarization through a dynamics lens, offering insights for addressing challenges in network governance within the social media era.
