- Abstract:
- The global rise of political polarization has fueled concerns about its detrimental impact on politics and society. From an increase in political violence to a decrease in the quality of democracy and governance, the threats posed by pernicious polarization—the division of society into two mutually antagonistic political camps—are diverse and acute. Determining how to reduce these tensions is therefore an urgent challenge. Using data on political polarization from the Varieties of Democracy (V-Dem) data set, this working paper assesses various instances of depolarization around the globe since 1900 and analyzes their long-term sustainability. Polarization is increasing worldwide. When broken down by region, V-Dem data suggest that every region except Oceania has seen polarization levels rise since 2005. Africa has had the smallest increase during this period, although it has long had high levels of polarization. Rising polarization in Europe is being driven by deepening political divisions in Eastern and Central Europe, Southern Europe, and the Balkans. In the Western Hemisphere, the largest democracies—Brazil, Mexico, and the United States—are all experiencing extreme levels of polarization. East Asia’s polarization levels have traditionally been low, though increasing political tensions in places like South Korea and Taiwan are driving up the region’s score. And in South Asia, India’s polarization has skyrocketed since 2014. Jennifer McCoy Jennifer McCoy is a nonresident scholar in the Democracy, Conflict, and Governance Program, where she focuses on political polarization and democratic resilience in the U.S. and around the world. To better understand the various paths by which polarized societies might overcome or reduce their political divisions, this working paper examines perniciously polarized countries that have successfully depolarized, at least for a time. Through a quantitative analysis of the V-Dem data set, this study identifies 105 episodes from 1900 to 2020 where countries were able to reduce polarization from pernicious levels for at least five years. These 105 episodes represent roughly half of the total episodes of pernicious polarization during the time period, thus indicating a fairly robust capacity of countries to depolarize. If considered in terms of country experiences rather than episodes (because many countries have experienced multiple episodes in a cycle of polarization and depolarization), then the data indicate that two-thirds of the 178 countries for which V-Dem provides polarization data have experienced one or more episodes of pernicious polarization, but only thirty-five countries (20 percent) have failed to experience any depolarization to below-pernicious levels. Given this apparent capacity among the majority of the world’s countries to depolarize from pernicious levels at least some of the time, this analysis seeks to identify the contexts and sustainability of those experiences and to encourage further research into their causal mechanisms and outcomes for democracies. The analysis offers a preliminary discussion of the potential meaning and normative implications of depolarization as a concept and policy goal. It then uses qualitative analysis to identify patterns in the contexts of various depolarization cases and gauge the sustainability of these trends. Most of these depolarization episodes were associated with dramatic changes in a country’s political life. An analysis of contextual factors showed that almost three-quarters of the cases came after major systemic shocks: a foreign intervention, independence struggle, violent conflict, or regime change (primarily in a democratizing direction). In the remainder of cases, countries depolarized within a given regime structure, whether democratic or autocratic. Tellingly, the authors identified no cases of depolarization from pernicious levels among liberal democracies. This is because very few countries classified as full liberal democracies have ever reached pernicious levels; the United States stands out today as the only wealthy Western democracy with persistent levels of pernicious polarization. Just under half of all depolarizing cases were able to sustain depolarization for a decade or longer. In a second sizeable group of cases, countries managed polarization to some degree, either living with chronic near-pernicious levels after depolarizing, or else repolarizing to near-pernicious levels within ten years. Finally, 15 percent of the cases returned to pernicious levels within the first decade. Troublingly, when the authors analyzed the entire time period from 1900 to 2020, nearly half of the countries that had sustained depolarization or managed polarization for at least a decade later returned to pernicious levels of polarization. These outcomes illustrate the difficulty of sustaining low levels of polarization, and they indicate that a cyclical pattern of polarization, depolarization, and repolarization may be a characteristic feature of political life in many places. Only a fraction (14 percent) of cases resulted in sustained depolarization over the long term.The mechanisms and strategies that enable such sustained depolarization in democracies will be the subject of future research. But given the small number of democracies (eleven) able to accomplish this feat amid the larger pattern of cyclical polarization and depolarization, it will be crucial to also understand strategies of managing polarization at moderately high levels while avoiding democratic erosion, government dysfunction, or returns to pernicious polarization and potential violence.
