Recently, researchers and reporters have made a wide range of claims about the distribution, nature, and societal impact of political polarization. Here I offer reasons to believe that even when they are correct and prima facie merely descriptive, many of these claims have the highly negative side effect of increasing political polarization. This is because of the interplay of two factors that have so far been neglected in the work on political polarization, namely that (1) people tend to conform to descriptive norms (i.e., norms capturing [perceptions of] what others commonly do, think, or feel), and that (2) claims about political polarization often convey such norms. Many of these claims thus incline people to behave, cognize, and be affectively disposed in ways that contribute to social division. But there is a silver lining. People's tendency to conform to descriptive norms also provides the basis for developing new, experimentally testable strategies for counteracting political polarization. I outline three.

Do party policy offerings simply reflect public opinion or do parties shape public demand for policies? Theories of party position-taking and the operation of democracy expect parties to track their supporters' positions, while scholarship of public opinion has shown voters often adopt the position of their preferred parties. We apply both of these theoretical expectations to the relationship between citizen polarization and party polarization and additionally argue that the relationship between them should be stronger among politically more engaged and sophisticated citizens. We draw on aggregated survey data from 174 cross-national and national election studies from 19 established democracies, to assess the extent to which citizen polarization responds to party polarization, the extent to which parties respond to changes in citizen polarization, and whether these relationships differ across different groups of citizens. We estimate seemingly unrelated error-correction models employing data on party and citizen positions from 1971 to 2019. Our findings suggest that citizen polarization follows party polarization and also that politically engaged and sophisticated citizens are more responsive to changes in party polarization than the politically less engaged and unsophisticated. In contrast, we find little evidence that party polarization responds to changes in citizen polarization.
Failures of government policies often provoke opposite reactions from citizens; some call for a reversal of the policy while others favor its continuation in stronger form. We offer an explanation of such polarization, based on a natural bimodality of preferences in political and economic contexts, and consistent with Bayesian rationality.
The increased polarization in the United States among the political branches and citizenry affects the selection, work, perception, and relative power of state and federal judges, including justices of the US Supreme Court. Polarization in the United States over the last few decades matters to the American judicial system in at least four ways. First, polarization affects judicial selection, whether the selection method is (sometimes partisan-based) elections or appointment by political actors. In times of greater polarization, governors and presidents who nominate judges, legislators who confirm judges, and voters who vote on judicial candidates are more apt to support or oppose judges on the basis of partisan affiliation or cues. Second, driven in part by selection mechanisms, polarization may be reflected in the decisions that judges make, especially on issues that divide people politically, such as abortion, guns, or affirmative action. The Supreme Court, for example, often divides along party and ideological lines in the most prominent and highly contested cases. Those ideological lines now overlap with party as we enter a period in which all the Court liberals have been appointed by Democratic presidents and all the Court conservatives have been appointed by Republican presidents. Third, increasingly polarized judicial decisions appear to be causing the public to view judges and judicial decision making (at least on the US Supreme Court) through a more partisan lens. Fourth, polarization may affect the separation of powers, by empowering courts against polarized legislative bodies sometimes paralyzed by gridlock. The review concludes by considering how increased polarization may interact with the judiciary and judicial branch going forward and by suggesting areas for future research.
