This chapter explores the possibilities and dilemmas that civil society actors face in resisting and reversing democratic backsliding through examples from around the world. It examines the conditions that shape civil society activism under backsliding and the roles it has played in containing or reversing autocratization. As it shows, in a number of cases civil society resistance has been critical in restraining and reversing backsliding. But it has been better able to counter backsliding when popular support for the backsliding leader has eroded and the opposition is able to work through institutions rather than having to work against them. As backsliding proceeds, institutional channels for influence deteriorate. As a result, there is a critical window during which civil society resistance stands a better chance of containing backsliding: before electoral processes and institutional constraints on executives are fully captured. Once capture occurs, civil society resistance moves to the much more dangerous and difficult task of confronting rather than preventing dictatorship.
The chapter introduces in a unified manner all ferroic materials including the three main ferroic systems, namely ferromagnetic, ferroelectric and ferroelastic, in addition to the case of materials that can display ferrotoroidic order. General physical aspects of magnetism, electricity and elasticity are used in order to introduce the order parameters that conveniently describe all these classes of ferroic phase transitions. It is shown that while the order parameter has a vectorial nature for ferromagnetic (axial vector), ferroelectric (polar vector) and magnetic ferrotoroidal (axial vector) systems, it is a rank-2 polar tensor in ferroelastic materials. The resulting physical differences arising from the different nature of the order parameter are then analysed in detail. Next, it is shown how to construct a convenient Ginszburg–Landau free energy functional in terms of these order parameters and their coupling for the different ferroic systems besides how to obtain the corresponding phase diagrams and microstructural features.
This chapter presents the tools for the comparative institutional analysis of amendments. It defines the core of a constitution as the provisions that cannot be altered given the amendment rules and the preferences of the relevant actors. The larger the core, the fewer and less significant the amendments. This simple rule is used to calculate an institutional index of rigidity of each constitution. Given that the preferences of the actors are not known, the index is based only on the amendment provisions and provides a necessary but not sufficient condition for amendments: When the constitution has high rigidity, amendments will be rare and/or insignificant, but when the constitution has low rigidity, there may or may not be frequent and/or significant amendments.
Do ideologically extreme candidates enjoy fundraising advantages over more moderate candidates? Extant work documents a relationship between candidates’ positions and campaign contributions subnationally and in donor surveys, yet identification challenges have hampered investigation in the congressional context. I employ a close primaries regression discontinuity design to examine how “as-if random” nominations of extreme versus moderate House candidates influence general election contributions from individual donors and corporate political action committees (PACs) from 1980 to 2020. Results at both the nominee and contributor levels demonstrate that corporate PACs financially penalize extremists, while individual donors respond similarly to extreme and moderate candidates. These findings contribute to ongoing debates regarding the extent and nature of campaign contributors’ role in congressional polarization.
During the coronavirus pandemic in the United Kingdom, media outlets shifted their focus from divisive political issues to more neutral topics like lifestyle, sports, and entertainment. This study explores how this change in media content relates to partisan divides in satisfaction with democracy. Using data from a representative survey of 201,144 individuals, we linked respondents’ perceptions of democratic performance to their daily media exposure. We did so by analysing 1.5 million tweets from British newspapers using a topic modelling algorithm to identify shifts in topic salience and sentiment using sentiment analysis. Our findings reveal a decline in partisan media exposure during the pandemic, associated with increased satisfaction with democracy at both individual and collective levels, and a narrowing of cross-party divides. These results contribute to discussions on affective polarization, the winner-loser gap in democratic evaluation, and media framing effects, highlighting the potential influence of depoliticized news coverage on democratic attitudes.
How does polarized politics affect electoral accountability? In this paper, I investigate the impact of political polarization on two channels through which voters can sanction incumbents for poor policy outcomes: voting for the opposition and abstaining. Using presidential election results at the county level, I show that, under polarized environments, the number of voters punishing the incumbent party for poor economic performances decreases in both channels. Survey analyses confirm that as the perceived ideological distance between parties increases, partisans are less likely to (i) negatively evaluate the economy when their party holds the Presidency and (ii) among those who have a negative view of the economy, they are less likely to penalize their party for negative economic assessments. These results show that polarization affects economic evaluation and clouds the responsibility for economic conditions, decreasing voters’ willingness to sanction the incumbent party.
This is a study of the dynamics of partisan polarization in the United States. It has three objectives: (1) to identify and explain why some Republicans and Democrats – but not others – have polarized, particularly over the last twenty years; (2) to demonstrate that they have done so not on this or that issue but systematically, programmatically – domain versus issue sorting; and (3) to bring into the open profound asymmetries in polarization between the two parties, not least that Republicans polarized early and thoroughly on issues of race, while Democrats in the largest number stayed neutral or even conservative until only recently. Emerging from the reasoning and results is a revised theory of party identification that specifies the conditions under which ordinary Republicans and Democrats can become ideological partisans – real-life conservatives and liberals in their behavior – in the choices they make on candidates, policies, and parties.
Does political polarization lead to dysfunctional behavior? To study this question, we investigate the attitudes of supporters of Donald Trump and of Hillary Clinton towards each other and how these attitudes affect spiteful behavior. We find that both Trump and Clinton supporters display less positive attitudes towards the opposing supporters compared to coinciding supporters. More importantly, we show that significantly more wealth is destroyed if the opponent is an opposing voter. This effect is mainly driven by Clinton voters. This provides the first experimental evidence that political polarization leads to destructive behavior.
Four ways of considering partisanship and factionalism dominated the political landscape of the nineteenth-century United States: the residual anti-party views of classical republicans, who were often drawn to a traditional politics of deference involving voluntary allegiance to leaders of a higher class who would advance the “common good”; James Madison’s view that multiple factions, in shifting configurations extending across a large geographic expanse, could prevent majorities from dominating minorities; the stance of those like Andrew Jackson who believed that parties harnessed the power of the people, whose interests would otherwise suffer neglect or worse from elite leaders; and finally, the fear of a polarizing, two-party system expressed by John Adams evolved in the views of a Mugwump like Henry Adams, who held himself apart from partisan corruption without aspiring to restore the elite politics of deference. This chapter explores the presence of these varied approaches to partisanship and factionalism in literary works by Henry Adams, Hugh Henry Brackenridge, James Fenimore Cooper, William Ellery Channing, Ralph Waldo Emerson, Nathaniel Hawthorne, Harriet Beecher Stowe, Albion Tourgée, Sarah Orne Jewett, Mark Twain, and Simon Pokagon.
Mass polarization is one of the defining features of politics in the twenty-first century, but efforts to understand its causes and effects are often hindered by empirical challenges related to measurement and data availability. To address these challenges and provide a common standard of analysis for researchers, this Element presents the Polarization in Comparative Attitudes Project (PolarCAP). PolarCAP clearly defines polarization as a property of group relations and uses a Bayesian measurement model to estimate smooth panels of ideological and affective polarization across ninety-two countries and forty-nine years. The author uses these data to provide a descriptive account of mass polarization across time and space. They further show how PolarCAP facilitates substantive inference by applying it to three sets of variables often hypothesized as causes or consequences of polarization: institutional design, economic crisis, and democracy. Open-source software makes PolarCAP easily accessible to scholars and practitioners.
This chapter of the handbook discusses the moral dimensions of political attitudes and behavior. The authors argue that a person’s political views – both at the level of political ideology as a whole and views on specific matters of economic and social policy – are profoundly shaped by their beliefs about right and wrong. These political views in turn drive people’s political behavior, not just at the ballot box or on the campaign trail, but in the community more generally. One downside of the way in which moral convictions fuel political attitudes and behavior is that they tend to interfere with productive communication across partisan divides, fueling a kind of animosity that stifles cooperation and compromise. Divergence in people’s moral convictions, then, leads inexorably to political polarization and gridlock. To address this problem, the authors discuss a number of potentially promising interventions, some of which target individuals’ attitudes (e.g., promoting empathy, reducing negative stereotypes), and others that aim at improving the quality of interpersonal relationships (e.g., increasing contact, fostering dialogue across political divides).
Do external threats increase American bipartisanship? We subject this question to an experimental test. Leveraging the Biden and Trump administrations’ similar characterization of the China threat, we exposed American respondents to real-world primes about security threats from China, while randomizing the messenger of such primes. We find that the threat primes—regardless of the partisan identity of their messenger—boosted Democrats’ and Republicans’ support for assertive foreign policy in a largely parallel manner, thereby failing to reduce preference polarization. Importantly, there were no measurable changes across multiple indicators of affective polarization. These findings clarify the limits of external threats in uniting Americans, while also challenging recent perspectives that external threats—often colored by elite rhetoric—will further polarize the American public.
Ideological polarization between political parties is essential for meaningful electoral competition, but at its extreme can strain democratic functioning. Despite a widespread recognition that multiple divides structure contemporary party polarization in Europe, its prevailing conceptualization and measurement remain one-dimensional. To resolve this tension, we introduce a novel, multidimensional approach to party polarization. Our main focus is on whether different ideological divides reinforce or crosscut each other. We calculate the effective dimensionality of a policy space using the correlation matrix of parties’ positions, which accounts for how the dimensions interrelate. Using both artificial data and positional estimates from the Chapel Hill Expert Survey (1999–2019), we highlight the advantages of our approach and demonstrate that it is better able to capture the relationship between party polarization and mass partisanship. This study has important theoretical, methodological, and empirical implications for our understanding of polarization and democratic representation in a changing political landscape.
A single-layer polarization converting metasurface (PCMS) with wideband is presented for polarization conversion and radar cross-section (RCS) reduction. The proposed PCMS is composed of metallic biconic shape resonator imprinted on a metal-backed F4BM dielectric substrate of relative permittivity 2.2 and loss tangent 0.001. The unit cell has a compact size of 0.16$\lambda_\mathrm{o} \times 0.16\lambda_\mathrm{o}$. A comprehensive parametric analysis, angular sensitivity study, bistatic and monostatic RCS analysis are conducted by illuminating the proposed PCMS using linearly polarized (LP) plane waves. The PCMS converts LP electromagnetic waves to their orthogonal polarization state in the frequency band of 8.7–24.8 GHz resulting in polarization conversion ratio over 90% with a fractional bandwidth of 96%. Additionally, the developed structure is applied in chessboard configuration, using phase cancellation techniques for RCS reduction, that achieve 10 dB RCS reduction across a wideband of 7.9–23.4 GHz. The unit cell and its rotated version has a cross-polarization reflection phase difference of (${180}\pm {37}{^\circ}$) in the operating band, which fulfill the criteria for RCS reduction. The chessboard configuration exhibits a scattering pattern with four strong lobes that deviates from the normal incident path because of the phase cancellation in normal direction. The experimental results are in good agreement with the simulated result. Applications for the developed structure include antenna design (gain enhancement and beam steering), target hiding, imaging, and microwave communications.
The conclusion summarizes the book’s arguments concerning the influence of polarization and the fracturing of norms on the judicial process, and also its remedial suggestions.
About two-thirds of Americans support legal abortion in many or all circumstances, and this group finds itself a frustrated majority following the Supreme Court's 2022 decision in Dobbs v. Jackson Women's Health Organization which overturned the legal precedent set in Roe v. Wade. Previous scholarship argues intense minorities can secure favorable policy outcomes when facing off against a more diffuse and less motivated majority, creating incongruence between public opinion and policy. This Element focuses on the ways that preference intensity and partisan polarization have contributed to the current policy landscape surrounding abortion rights. Using survey data from the American National Election Studies, the authors identify Americans with intense preferences about abortion and investigate the role they play in electoral politics. They observe a shift in the relationship between partisanship and preference intensity coinciding with Dobbs and speculate about what this means for elections and policy congruence in the future.
Even amidst a decline in religious affiliation, nearly half of the U.S. population still attends religious services at least once a month, and congregations remain the single largest non-profit organizational type across the nation. Therefore, congregational influence on political attitudes and behavior is a crucial line of inquiry. We analyze interviews of 94 congregational leaders to better understand why they address or avoid political issues when preaching. Our research reveals that clergy use theological and pragmatic reasoning to determine whether they explicitly include political discourse in their sermons. Our findings are noteworthy in that clergy from a wide range of religious traditions use similar reasoning, and the same rationale can lead different clergy to adopt contrasting approaches to political content in sermons. Thus, this paper provides nuanced insight into the relationship between religion and politics and may help foster greater mutual understanding in a deeply divided political and social climate.
How can groups best coordinate to solve problems? The answer touches on cultural innovation, including the trajectory of science, technology, and art. If everyone acts independently, different people will explore different solutions, but there is no way to leverage good solutions across the community. If everyone acts in consort, early successes can lead the group down dead ends and stifle exploration. The challenge is one of maintaining innovation but also communicating effective solutions once they are found. When solutions spaces are smooth – that is, easy – communication is good. But when solution spaces are rugged – that is, hard – the balance should tilt toward exploration. How can we best achieve this? One answer is to place people in social structures that reduce communication, but maintain connectivity. But there are other solutions that might work better. Algorithms, like simulated annealing, are designed to deal with such problems by adjusting collective focus over time, allowing systems to “cool off” slowly as they home in on solutions. Network science allows us to explore the performance of such solutions on smooth and rugged landscapes, and provides numerous avenues for innovation of its own.
This chapter uses data from the Dataset of Parties, Elections, and Ideology in Latin America (DPEILA) to understand the recent rightward move being seen in many party systems within the region, as well as the subsequent process of party-system polarization. The authors argue that major economic downturns favor radical, antisystem alternatives, thereby creating an opportunity for newly created parties to campaign on extreme policy platforms. They also demonstrate that polarization increases when leftist incumbents are associated with progressive policy change, as right-wing parties have become more ideologically extreme. This indicates that the left turn of the 2000s has at times favored the radicalization of important sectors of the right.
In the conclusion, we review the book’s chapters and argue that Latin America has experienced a resurgence of conservative forces in recent years. We analyze the supply and demand of a broad set of conservative alternatives, paying special attention to the processes of party-building, adaptation, and rebranding. We find that new right-wing forces often have weak organizations, but have been able to mobilize voters along noneconomic cleavages, including security, gender politics, and reproductive rights. The adoption of a highly conservative profile has allowed parties to access lower-class constituencies and mobilize mass support among them. The politicization of cultural issues, such as LGBT rights and religious identities, has contributed to polarization and the rise of populist radical right parties. These parties have flourished within the context of political and economic shocks and benefited from cultural backlashes and the crises of traditional right-wing parties. In these situations, politics becomes a zero-sum game and the stakes get higher. Democratic stability in the region is arguably at its most tenuous state since the age of military dictatorships. Interrupted presidencies have become realities in many countries over the past fifteen years, raising concerns about democratic stability and potential threats to democratic institutions.
