Affective polarization is increasingly studied comparatively, and virtually all studies that do so operationalize it using the feeling thermometer. Yet this survey instrument has not yet been validated in a multi-party context. We argue that for the thermometer to be a valid measure of partisan affect also in multi-party systems, it needs to captur...

Concerns over democratic backsliding have proliferated recently, as elected politicians have sought to undermine democratic checks and balances. This study examines the underpinnings of public support for democratic backsliding, delineating five theoretical explanations: personalistic leadership, affective polarization, populism, majoritarianism, a...

There is a broad consensus that the ideological space of Western democracies consists of two distinct dimensions: one economic and the other cultural. In this Element, the authors explore how ordinary citizens make sense of these two dimensions. Analyzing novel survey data collected across ten Western democracies, they employ text analysis techniqu...

Measures of affective polarization—that is, dislike and hostility across party lines—have been developed and validated in the context of America’s two-party system. Yet increasingly, affective polarization is examined comparatively. We address this issue by introducing a novel dataset that measures aspects of partisan affect in 10 countries with di...

Affective polarization measures account for partisans’ feelings towards their own party versus its opponent(s), but not for how likely partisans are to encounter co-partisans versus out-partisans. However, the intensity of out-party dislike and the probability with which this comes into play both determine the social impact of cross-party hostility...

These are challenging times for journalists’ relationship with their audiences. Attacks against “the media” and the increasing weaponization of social media to harass journalists have drawn the attention of scholars worldwide. In the current climate, journalists are not only distrusted but also hated, which creates a series of distinct ramification...

While scholars have closely examined the intensification of negative affect across party lines during elections, less is known about the decline of partisan hostility in the aftermath of election campaigns. Synthesizing insights from research on electoral rules and political psychology, we theorize and empirically test two such mechanisms of post‐e...

Concerns over democratic backsliding have proliferated recently, as elected politicians have sought to undermine democratic checks and balances. This study examines the underpinnings of public support for democratic backsliding, delineating five theoretical explanations: personalistic leadership, affective polarization, populism, majoritarianism, a...

Sociological research on online discourse increasingly uses digital data consisting of messages combining multiple modes of media, with meaning arising from contents’ interaction across modes. Yet, techniques to study this interplay are underdeveloped relative to the toolkit for analyzing solely texts. The authors introduce an automated approach fo...

While scholars increasingly link affective polarization to the rise of populist parties, existing empirical studies are limited to the effects of radical right parties, without considering the possible effects of leftist populist parties or of parties' varying degrees of populism. Analyzing novel survey data across eight European publics, we analyz...

While dislike of opposing parties, that is, affective polarization, is a defining feature of contemporary politics, research on this topic largely centers on the United States. We introduce an approach that analyzes affective polarization between pairs of parties, bridging the US two-party system and multiparty systems in other democracies. Analyzi...

Affective polarization measures account for partisans’ feelings towards their own party versus its opponent(s), irrespective of how frequently partisans encounter co-partisans versus out-partisans in everyday interactions and public discourse. However, the social impact of cross-party hostility depends on both the intensity of dislike and the frequ...

Research on affective polarization – that is, dislike and hostility across party lines – originated in the study of the American two-party system and only recently traveled into multiparty contexts. This emerging body of research is hindered by lack of comprehensive data that capture multiple dimensions of polarization and examine how they develop...

Concern over partisan resentment and hostility has increased across Western democracies. Despite growing attention to affective polarization, existing research fails to ask whether who serves in office affects mass-level interparty hostility. Drawing on scholarship on women’s behavior as elected representatives and citizens’ beliefs about women pol...

Comparative politics scholars argue that consensual democratic institutions encourage power-sharing that promotes “kinder, gentler” politics. We uncover one reason why this is the case: elite inter-party cooperation in consensual systems is associated with reduced inter-party hostility in the mass public. This is because governing parties’ supporte...

Scholars have argued that immigrants’ trust in institutions is the result of the exposure to host-country institutions but also shaped by past experiences in the country of origin. These experiences create a “home-country point of reference,” a political/institutional memory that becomes the relevant comparison for any political/institutional inter...

(Forthcoming The Journal of Legal Studies 2022) Western societies are increasingly enacting majority nationalism laws to strengthen majority culture. We propose that these laws may alter public attitudes about minorities’ equal citizenship with varied impact on majorities and minorities. To explore this issue, we examine the impact of Israel’s rec...

American political observers express increasing concern about affective polarization, i.e., partisans' resentment toward political opponents. We advance debates about America's partisan divisions by comparing affective polarization in the US over the past 25 years with affective polarization in 19 other western publics. We conclude that American af...

Mainstream parties in Western Europe are increasingly struggling to hold together their base of support. As a lens for exploring this changing electoral landscape, this article focuses on the growing share of the electorate that is cross-pressured between conservative and progressive attitudes on economic and cultural issues. It argues that a stabl...

We argue that support for parties of the radical right and left can usefully be understood as a problem of social integration—an approach that brings together economic and cultural explanations for populism. With comparative survey data, we assess whether support for parties of the radical right and left is associated with feelings of social margin...

Political developments since the 2008 financial crisis have sparked renewed interest in the electoral implications of economic downturns. Research describes a correlation between adverse economic conditions and support for radical parties campaigning on the populist promise to retake the country from a corrupt elite. But does the success of radical...

This review proposes a comparative research agenda on center-right parties in advanced democracies, bringing together research in American and comparative politics. Political scientists have recently closely examined the decline of the center-left and the rise of the radical right but have paid less attention to the weakening of center-right partie...

Western societies have experienced ethnic and religious diversification in recent decades. These demographic changes have been met by efforts to defend the local dominant culture using majority nationalism laws, intended to protect the cultural heritage of the majority. We empirically examine majority nationalism laws’ expressive effects on pattern...

Western societies have been going through significant processes of racial, ethnic and religious diversification in recent decades that were met with a growing effort to defend majority culture using legal instruments. Majority nationalism laws have raised concerns regarding their potential impact on intergroup relations, and particularly minority d...

It is well-established that in diverse societies, certain groups prefer to exclude other groups from power and often from society entirely. Yet as many societies are diversifying at an increasingly rapid pace, the need for cross-group cooperation to solve collective action problems has intensified. Do preferences for exclusion inhibit the ability o...

This paper explores the factors that have recently increased support for candidates and causes of the populist right across the developed democracies, especially among a core group of working-class men. In the context of debates about whether the key causal factors are economic or cultural, we contend that an effective analysis must rest on underst...

What role has the US Supreme Court played in the liberalization of the American economy over the last three decades? By examining more than 800 cases of judicial review on issues related to economic policy-making between 1946 and 2012, we show that the Court participated in the post-1980s shift to the market economy through disciplining non-complyi...

This contribution to the APSA Comparative Politics Newsletter provides an introduction to the conceptualization of populism. As we explain, there are three main traditions in populism research: populism as a political strategy, populism as a political ideology, and populism as a discursive style. Each of these traditions imply different levels of a...

Why are the negative effects of social diversity more pronounced in some places than in others? What are the mechanisms underlying the relationship between diversity and discriminatory behaviors, and why do they vary in prevalence and strength across locations? Experimental research has made advances in examining these questions by testing for diff...

This paper examines populist claims-making in US presidential elections. We define populism as a discursive strategy that juxtaposes the virtuous populace with a corrupt elite and views the former as the sole legitimate source of political power. In contrast to past research, we argue that populism is best operationalized as an attribute of politic...

In recent years, populism has attracted considerable interest from social scientists and political commentators. Yet the term ‘populism’ remains both widely used and widely contested. It has been defined based on political, economic, social, and discursive features and analyzed from myriad theoretical perspectives and a variety of methodological ap...
