The Balance of Power in World Politics  

Randall L. Schweller

The balance of power—a notoriously slippery, murky, and protean term, endlessly debated and variously defined—is the core theory of international politics within the realist perspective. A “balance of power” system is one in which the power held and exercised by states within the system is checked and balanced by the power of others. Thus, as a nation’s power grows to the point that it menaces other powerful states, a counter-balancing coalition emerges to restrain the rising power, such that any bid for world hegemony will be self-defeating. The minimum requirements for a balance of power system include the existence of at least two or more actors of roughly equal strength, states seeking to survive and preserve their autonomy, alliance flexibility, and the ability to resort to war if need be. At its essence, balance of power is a type of international order. Theorists disagree, however, about the normal operation of the balance of power. Structural realists describe an “automatic version” of the theory, whereby system balance is a spontaneously generated, self-regulating, and entirely unintended outcome of states pursuing their narrow self-interests. Earlier versions of balance of power were more consistent with a “semi-automatic” version of the theory, which requires a “balancer” state throwing its weight on one side of the scale or the other, depending on which is lighter, to regulate the system. The British School’s discussion of balance of power depicts a “manually operated” system, wherein the process of equilibrium is a function of human contrivance, with emphasis on the skill of diplomats and statesmen, a sense of community of nations, of shared responsibility, and a desire and need to preserve the balance of power system. As one would expect of a theory that made its appearance in the mid-16th century, balance of power is not without its critics. Liberals claim that globalization, democratic peace, and international institutions have fundamentally transformed international relations, moving it out of the realm of power politics. Constructivists claim that balance of power theory’s focus on material forces misses the central role played by ideational factors such as norms and identities in the construction of threats and alliances. Realists, themselves, wonder why no global balance of power has materialized since the end of the Cold War.


Gender and Political Behavior  

Miki Caul Kittilson

The burgeoning field of gender and political behavior shows that the way in which ordinary citizens connect to the democratic process is gendered. Gender differences in voting behavior and participation rates persist across democracies. At the same time, countries vary substantially in the size of these gender gaps. In contemporary elections, women tend to support leftist parties more than men in many countries. Although men and women vote at similar rates today, women still trail men in important participatory attitudes and activities such as political interest and discussion. Inequalities in political involvement undermine the quality of deliberation, representation, and legitimacy in the democratic process. A confluence of several interrelated factors (resources, economy, socialization, political context) work together to account for these differences. Today, scholars more carefully consider the socially constructed nature of gender and the ways in which it interacts with other identities. Recent research on gender and political behavior suggests that political context affects different kinds of women in different ways, and future research should continue to investigate these important interactions.


Party Identification and Its Implications  

Russell J. Dalton

Early electoral research in the United States discovered the most important concept in the study of political behavior: party identification. Party identification is a long-term, affective attachment to one’s preferred political party. Cross-national research has found that these party identities are a potent cue in guiding the attitudes and behavior of the average person. Partisans tend to repeatedly support their preferred party, even when the candidates and the issues change. Party ties mobilize people to vote to support their party, and to work for the party during the campaign. And, given the limited information most people have about complex political issues, party ties provide a cue to what positions one should support. This review describes how the level of partisanship among contemporary publics varies across nations and across time, and how these patterns have significant implications for democracies today.


Real-Time Responses to Campaign Communication  

Marcus Maurer

Real-time response measurement (RTR), sometimes also called continuous response measurement (CRM), is a computerized survey tool that continuously measures short-time perceptions while political audiences are exposed to campaign messages by using electronic input devices. Combining RTR data with information about the message content allows for tracing back viewers’ impressions to single arguments or nonverbal signals of a speaker and, therefore, showing which kinds of arguments or nonverbal signals are most persuasive. In the context of applied political communication research, RTR is used by political consultants to develop persuasive campaign messages and prepare candidates for participation in televised debates. In addition, TV networks use RTR to identify crucial moments of these debates and sometimes even display RTR data during their live debate broadcasts. In academic research most RTR studies deal with the persuasive effects of televised political ads and especially televised debates; the studies sometimes include hundreds of participants rating candidates’ performances during live debate broadcasts. In order to capture features of human information processing, RTR measurement is combined with other data sources like content analysis, traditional survey questionnaires, qualitative focus group data, or psychophysiological data. Those studies answer various questions on the effects of campaign communication including which elements of verbal and nonverbal communication explain voters’ short-term perceptions of campaign messages, which predispositions influence those perceptions, and the extent to which voters’ opinions are explained by short-term perceptions versus long-term predispositions. In several such studies, RTR measurement has proven to be reliable and valid; it appears to be one of the most promising research tools for future studies on the effects of campaign communication.



Erica Frantz

Dictatorships have dominated global politics for hundreds of years, from the pharaohs of Egypt to the absolute monarchs of Europe. Though democracy has since spread to much of the world, about 40% of today’s countries are still ruled by dictatorship. And yet, compared with democracies, we know very little about how dictatorships work, who the key political actors are, and where decision making powers lie. Political processes are opaque, and information is often intentionally distorted. Political survival depends not on maintaining the favor of voters, as in democracies, but on securing the backing of a considerably smaller coalition of supporters. The absence of a reliable third party to enforce compromises among key players means that power-sharing deals lack credibility, and the threat of forced ouster is omnipresent. Uncertainty pervades authoritarian politics. Modern autocrats respond to this uncertain environment in a variety of ways. They use political parties, legislatures, elections, and other institutions typically associated with democracies to lessen their risk of overthrow. Despite the façade of democracy, these institutions are key components of most autocrats’ survival strategies; those that incorporate them last longer in power than those that do not. The specific ways in which autocratic institutions are used and the extent to which they can constrain leadership choices to prevent consolidation of power into the hands of a single individual, however, vary enormously from one dictatorship to the next. Better understanding the conditions that push autocracies down a path of collegial versus strongman rule remains a critical task, particularly given that the latter is associated with more war, economic mismanagement, and resistance to democratization.


Candidates and Voting Choice  

Ian McAllister

The role of candidates in shaping voting choice has generated much research—and at least as much controversy—since modern electoral behavior research began in the 1960s. Much of the controversy surrounds the personalization of politics and whether political systems—and especially parliamentary systems—are becoming more leader-oriented. Three fundamental changes in electoral behavior underpin the study of candidates and voting choice behavior: the declining impact of social structure on the vote; partisan dealignment, with voters drifting away from their traditional party attachments; and the decline in the mass memberships of political parties. Researchers argue that because of these changes, fostered by the growth of television, candidates have assumed a greater role in structuring the vote. While there is impressionistic evidence that leaders have become more important, empirical evidence of an underlying change in voter behavior is more difficult to identify. Accordingly, this essay focuses mainly on changes in the political context within which candidates operate, since we expect this to be the source of any change. The design of political institutions shapes the level of attention that candidates receive, and that is especially the case with electoral systems. Electoral systems with fewer parties are more likely to focus voters’ attentions on candidates when compared to systems with larger numbers of parties. Weak party organizations coupled with partisan dealignment within the electorate can also alter the role and profile of candidates, although their impact is difficult to quantify. Changes in the mass media—and particularly the advent of television in the 1960s and the visual images on which it relies—are often viewed as the major cause of the personalization of politics. A new disruptive technology, the Internet, looks likely to stimulate additional political change for candidates and voting in the 21st century. Finally, what voters look for in their candidates appears to be stable both over time and cross-nationally and can be reduced to two overarching qualities: character and competence.


Public Opinion and Public Policy  

Christopher Wlezien and Stuart N. Soroka

The link between public opinion and public policy is of special importance in representative democracies, as we expect elected officials to care about what voters think. Not surprisingly, a large body of literature tests whether policy is a function of public preferences. Some literature also considers the mechanisms by which preferences are converted to policy. Yet other work explores whether and how the magnitude of opinion representation varies systematically across issues and political institutions. In all this research, public opinion is an independent variable—an important driver of public policy change—but it is also a dependent variable, one that is a consequence of policy itself. Indeed, the ongoing existence of both policy representation and public responsiveness is critical to the functioning of representative democracy.


Public Opinion on Foreign Policy Issues  

Richard C. Eichenberg

Scholars and governments are interested in four sets of questions concerning public opinion on foreign policy and national security policy. First, what do public opinion polls measure? How do citizens, who are generally uninformed about foreign policy and world affairs, form opinions on these matters? Second, how rational is public opinion? Is it stable or volatile? Are opinions coherent? Do opinions plausibly reflect the flow of world events? Third, what factors influence the formation of citizen opinions? Specifically, what is the impact of fundamental attitudes toward war and military force, partisanship, ideology, and gender? Finally, how universal are the determinants of citizen opinion, especially on crucial issues of war and peace? Are the findings in global comparisons the same as those in the American or European contexts? Considerable scholarship has been devoted to these four questions. Scholars now characterize public opinion as rational, in the sense that it is fairly stable, coherent, and responsive to real world events. Attitudes toward war and military force are a major focus of the research literature because many specific policy attitudes flow from fundamental views of war. Gender has also become a major focus of research because many studies find that women are less supportive of the use of military force for most purposes. Finally, scholars are beginning to discover that some opinion patterns are universal across societies, while others are more affected by the individual characteristics of national societies. Studies of global public opinion have expanded greatly, with recent scholarship focusing on global attitudes toward gender equality, immigration, and climate change.


Modern Populism: Research Advances, Conceptual and Methodological Pitfalls, and the Minimal Definition  

Takis S. Pappas

Populism is one of the most dynamic fields of comparative political research. Although its study began in earnest only in the late 1960s, it has since developed through four distinct waves of scholarship, each pertaining to distinct empirical phenomena and with specific methodological and theoretical priorities. Today, the field is in need of a comprehensive general theory that will be able to capture the phenomenon specifically within the context of our contemporary democracies. This, however, requires our breaking away from recurring conceptual and methodological errors and, above all, a consensus about the minimal definition of populism. All in all, the study of populism has been plagued by 10 drawbacks: (1) unspecified empirical universe, (2) lack of historical and cultural context specificity, (3) essentialism, (4) conceptual stretching, (5) unclear negative pole, (6) degreeism, (7) defective observable-measurable indicators, (8) a neglect of micromechanisms, (9) poor data and inattention to crucial cases, and (10) normative indeterminacy. Most, if not all, of the foregoing methodological errors are cured if we define, and study, modern populism simply as “democratic illiberalism,” which also opens the door to understanding the malfunctioning and pathologies of our modern-day liberal representative democracies.
