Abstract

The study of political polarization has undergone significant conceptual and methodological evolution, progressing from early emphases on ideological divides toward a more complex understanding that incorporates affective, identity-based, digital, and cross-national dimensions. This shift reflects the growing recognition that polarization is not merely a divergence of policy preferences, but a multifaceted phenomenon shaped by emotional, social, technological, and epistemic processes. In this review, we provide an elaboration of the various ways to approach the study of political polarization. This task may be daunting, but a well-organized, comprehensive and interdisciplinary overview is surely necessary. We begin by elaborating different types of political polarization, moving from an early focus on ideological divides to multidimensional constructs. Then, we shift to an overview of key disciplinary concepts and theoretical approaches for examining political polarization. At the heart of this review, we elaborate the various methodologies and methods for studying polarization, including quantitative, computational/digital, experimental, and qualitative approaches. We also highlight the strengths and limitations of these methodologies. To conclude the review, we first offer some suggestions for interventions that could mitigate the effects of polarization, and second, point to directions for future research. We suggest expanding the national focus that has dominated the study of polarization, highlighting the benefits of cross-national comparisons with a global reach.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
