Political Polarization and Its Effect on Social Cohesion

Abstract

This study investigates the relationship between political polarization and social cohesion through a mixed-methods design combining quantitative regression models with qualitative case studies. The quantitative findings demonstrated a strong negative correlation between polarization intensity and social cohesion indicators, including interpersonal trust, civic engagement, and institutional confidence. Regression results confirmed that polarization significantly predicts lower cohesion, while mediation analysis revealed that institutional trust is a critical factor exacerbating the impact of polarization on society. Subgroup analysis showed notable variations across gender and geographic contexts, with women and urban populations reporting sharper declines in cohesion under polarized environments. Longitudinal trends indicated that polarization not only produces short-term fractures but also perpetuates cycles of fragmentation that weaken democratic resilience. Qualitative interviews and discourse analysis further highlighted how polarization manifests in identity-based divisions, echo chambers, and misinformation, deepening mistrust across groups and diminishing solidarity. Together, the findings underscore that while polarization may energize participation in the short term, its broader consequences are overwhelmingly detrimental to social cohesion. The study concludes that mitigating polarization’s effects requires strengthening institutional trust, promoting civic education, and adopting policies that reduce inequality and encourage inclusive dialogue.
