A prominent worry in the measurement of political knowledge is that respondents who say they don’t know the answer to a survey question may have partial knowledge about the topic—more than respondents who answer incorrectly but less than those who answer correctly. It has also been asserted that differentials in respondents’ willingness to guess, driven strongly by personality, can bias traditional knowledge measures. Using a multinomial probit item response model, I show that, contrary to previous claims that “don’t know” responses to political knowledge questions conceal a good deal of “hidden knowledge,” these responses are actually reflective of less knowledge, not only than correct responses but also than incorrect answers. Furthermore, arguments that the meaning of “don’t know” responses varies strongly by respondent personality type are incorrect. In fact, these results hold for high- and low-trait respondents on each of the five most commonly used core personality measures.

Private information and the commitment problem are central to the rationalist theory of war, but causal evidence is scarce, as rationalist explanations for war are difficult to test with observational data. I design laboratory experiments to isolate the effects of private information and the commitment problem on the risk of conflict. I find that the commitment problem sharply increases the incidence of conflict, but there is no significant difference in conflict incidence with or without private information in the shadow of shifting power. I also investigate the realism of the positive experimental results with a case study of Japan’s decisionmaking on the eve of the Pacific War. The permutation of formal, experimental and historical methods applies the strength of one method to compensate for the weakness of another. Convergent results from the different methods strengthen the causal inference.

While there is a substantial literature highlighting the presence of social dynamics in legislatures, we know very little about the precise processes that generate these social dynamics. Yet, whether social dynamics are due to peer pressure, frequency of interaction, or genuine learning, for example, has important implications for questions of political representation and accountability. We demonstrate how a recent innovation can be used to study the diffusion of behavior within legislatures. In particular, we study diffusion within the US House of Representatives by looking at the dynamic process underlying discharge petitions. The discharge procedure shares many characteristics with other forms of legislative behavior, yet it has one important advantage when it comes to studying social dynamics: we can observe when members decide to sign petitions. Based on data from 1995 to 2014, we find that the social dynamics underlying the discharge procedure tend to involve the rational evaluation of information conveyed by the behavior of previous petition signatories.

This paper examines the effects of survey mode on patterns of survey response, paying special attention to the conditions under which mode effects are more or less consequential. We use the Youth Participatory Politics survey, a study administered either online or over the phone to 2920 young people. Our results provide consistent evidence of mode effects. The internet sample exhibits higher rates of item non-response and “no opinion” responses, and considerably lower levels of differentiation in the use of rating scales. These differences remain even after accounting for how respondents selected into the mode of survey administration. We demonstrate the substantive implications of mode effects in the context of items measuring political knowledge and racial attitudes. We conclude by discussing the implications of our results for comparing data obtained from surveys conducted with different modes, and for the design and analysis of multi-mode surveys.

Recent empirical work scrutinizes the ability of economic sanctions to destabilize targeted leaders. Limitations in data and modeling choices, however, may have inflated estimates of sanctions’ efficacy. I propose a unified theoretical model, incorporating the possibility that leaders targeted with threats and imposed sanctions differ in baseline risks from those who are not. I combine this hazards approach with an empirical strategy to account for differences in ex ante risks and improved data on leader failure. This approach uncovers a considerably more modest effect. Sanctions rarely destabilize their targets.

Scholarly interest in the role of emotion in accounting for how people react to political figures, events, and messages has escalated over the past two plus decades in political science and psychology. However, research on the validity of the measurement of subjective self-report of emotional responses is rather limited. We introduce here a new measurement approach, a “slider” format and compare it with the long used “radio button” item format. We assess the reliability and validity of these two approaches to the measurement of affect. The study examines self-report measures of emotion to three generated news stories about terrorist threats. We report that both measurement formats are able to extract the expected threefold affect structure from a ten affect word battery. The slider format is, however, modestly more reliable, and more efficient in time to complete, has the ability to limit missing data, and generates continuous data that is less truncated than data derived from the radio button format. Finally, we report on three tests of construct validity. Both approaches exhibit equivalent results on two of those tests. However, the radio button format does poorly on one test of construct validity, that on the anticipated relationship between anxiety and interest in novel information. We present an assessment of two methods for measuring emotional reactions to stimuli such as political issues, political figures, or events. Both methods are suitable for use in online surveys or computer-driven experiments. The traditional method utilizes labeled “radio buttons” that enable a participant in a study to select by clicking on one of an array of typically five response options, ranging from lower to higher of some identified affect term (e.g., how angry one might feel). Second, the slider method offers a participant the ability to move an “arrow” up or down to indicate how much (up) or little (down) they feel. The goal of both measures is to ascertain the level of a targeted emotion, i.e., how little or how much, say anger. The slider method has been specifically developed to be used with participants using a computer. The slider approach falls within the category of visual analog scales. This method for measuring affective responses to stimuli of whatever sort has not hitherto been examined to determine its reliability and validity. The literature on the reliability and validity of these measurement strategies is thin and we found no studies including an explicit comparison.

We propose a new standard for evaluating the performance of electoral democracies: the correspondence between citizens’ party preferences and the party composition of governments that are formed after elections. We develop three criteria for assessing such correspondence: the proportion of citizens whose most preferred party is in government, whether the party that is most liked overall is in government, and how much more positively governing parties are rated than non-governing parties. We pay particular attention to the last criterion, which takes into account how each citizen feels about each of the parties as well as the intensity of their preferences. We find that proportional representation systems perform better on the first criterion. Majoritarian systems do better on the other two.

Various strands of literature in comparative politics suggest that there is a differential impact of the type of government and their supporting legislative coalitions in parliamentary democracies, for example, in terms of their size and ideological heterogeneity, and on their potential to induce policy change. Most studies in this area focus on governments as agenda-setters, possibly neglecting the role of parliaments as a further key actor in policy making. In this article, we address the broader question as to how patterns of conflict within parliament effect legislative activity of governments and parliamentary actors. Through a simultaneous analysis of the success and event history of over 12,000 legislative bills in three parliamentary systems and one semi-presidential system from 1986 until 2003, we show how the interplay of actor motivations and institutional settings has a discriminating impact on the potential of both the government and parliament to induce policy change.

This note illustrates a new method for making causal inferences with ecological data. We show how to combine aggregate outcomes with individual demographics from separate data sources to make causal inferences about individual behavior. In addressing such problems, even under the selection on observables assumption often made in the treatment effects literature, it is not possible to identify causal effects of interest. However, recent results from the partial identification literature provide sharp bounds on these causal effects. We apply these bounds to data from Chilean mayoral elections that straddle a 2012 change in Chilean electoral law from compulsory to voluntary voting. Aggregate voting outcomes are combined with individual demographic information from separate data sources to determine the causal effect of the change in the law on voter turnout. The bounds analysis reveals that voluntary voting decreased expected voter turnout, and that other causal effects are overstated if the bounds analysis is ignored.

Ballot initiatives and referendums are increasingly popular methods for addressing important political issues. Studies of voting in these events has found that people rely on party leader and candidate image heuristics when deciding how to cast their ballots. Some analysts have argued that these effects are heterogeneous, being larger for people with lower levels of political knowledge. However, research in experimental economics and political psychology suggests that the impact of heuristics may be greater among more knowledgeable individuals. This paper investigates these rival hypotheses using survey data on voting in a ballot initiative to repeal California’s climate change legislation. Analyses using methods appropriate for studying interaction effects in nonlinear multivariate models demonstrate that candidate heuristics are stronger among more knowledgeable people.

Coalition parties have to reconcile two competing logics: they need to demonstrate unity to govern together, but also have to emphasize their own profile to succeed in elections. We argue that the electoral cycle explains whether unity or differentiation prevails. While differentiation dominates at the beginning and the end of the legislative term in close proximity to elections, compromise dominates the middle of the term when coalition governments focus on enacting a common policy agenda. To test our theoretical claims, we draw on an innovative quantitative text analysis of more than 21,000 press releases published by coalition parties from 2000 until 2010.

We develop a theory of how an authoritarian regime interactively uses information manipulation, such as propaganda or censorship, and policy improvement to maintain social stability. The government can depict the status quo policy more popularly supported than it actually is, while at the same time please citizens directly by enacting a costly reform. We show that the government’s ability of making policy concessions reduces its incentive to manipulate information and improves its credibility. Anticipating a higher chance of policy concessions and less information manipulation, citizens are more likely to believe the government-provided information and support the regime. Our model provides an explanation for the puzzling fact that reform coexists with selective information disclosure in authoritarian countries like China.

Analyzing the British Election Study from 1964 to 2010, we examine the influence of electoral context on turnout, focusing on the closeness of elections in terms of lagged seat and constituency-level winning margins. Using cross-classified multilevel models to account for individual and contextual factors and disentangle life cycle, cohort- and election-specific effects, we find that closeness strongly affects voting behavior, particularly among new electors. Widening seat margins in British elections over the last decades have had a persistent impact on turnout. Respondents who faced less competitive environments when young are more likely to abstain in subsequent elections than those reaching voting age after close-fought races. We conclude that variations in competitiveness have had both short- and long-term effects on turnout.

This article considers the hypothesis that the positive actions taken by members of Congress (MCs) influence citizens’ evaluations of them, their party, and Congress as an institution. We begin with a look at the available cross-sectional survey data on contact with legislators and legislator and institutional approval. Their legislative responsiveness appears to have a small spillover effect on institutions. However, when we employ a unique panel design that controls for prior levels of opinion and avoids recall bias, we find no evidence of spillover effects. Overall, we find that constituents who received a response from their own MC evaluate that representative more positively than those who did not receive a response, but legislator responsiveness does not predict evaluations of the MC’s political party or the Congress.

Media freedom has motivated substantial political activism, yet there are surprising gaps in the related academic literature, in part because of a lack of historic and consistent data. We introduce the newly expanded Global Media Freedom Dataset, which includes 196 countries from 1948 to 2012, and demonstrate how it can be used to test previous hypotheses and assumptions about the correlates of media freedom.

The 2010 US Supreme Court’s decision on Citizens United v. Federal Electoral Commission lifted restrictions on the funding by unions and corporations of groups engaging in independent political advertising (outside spending). Many have criticized the majority opinion’s premise that outside spending cannot corrupt or distort the electoral process. Fewer have examined the implications of this decision under the Court’s assumptions. Using a game-theoretic model of electoral competition, we show that informative outside spending by a group whose policy preferences are partially aligned with the electorate may reduce voter welfare. This negative effect is more likely when policy information is highly valuable for the electorate or congruence between the group and voters is high. We further show that the regulatory environment produced by the Court’s decision is always suboptimal: the electorate would be better off if either groups were allowed to coordinated with candidates or if outside spending was banned altogether.

Within research on the political influence that social network members exert on one another, some studies rely on information obtained directly from different members in the network separately (self-reported measures), while others rely on information obtained from one key informant within the social network (measures based on perception). We investigate the difference between these self-reported and perceived measures by analyzing the correspondence of voting intentions within the family. On the one hand, we examine this correspondence using information obtained from only one family member. On the other hand, we use the self-reported measures obtained from all family members separately. We use data from the Parent-Child Socialization Study (PCSS), a survey conducted among 2,085 mothers, fathers and children in the Flemish region of Belgium (2012). Our analyses suggest that using perceptual measures could lead researchers to different or even opposite conclusions than using self-reported measures from all individual respondents.

Researchers studying electoral participation often rely on post-election surveys. However, the reported turnout rate is usually much higher in survey samples than in reality. Survey methodology research has shown that offering abstainers the opportunity to use face-saving response options succeeds at reducing overreporting by a range of 4–8 percentage points. This finding rests on survey experiments conducted in the United States after national elections. We offer a test of the efficacy of the face-saving response items through a series of wording experiments embedded in 19 post-election surveys in Europe and Canada, at four different levels of government. With greater variation in contexts, our analyses reveal a distribution of effect sizes ranging from null to minus 18 percentage points.

We examine a major source of heterogeneity across cases in the Correlates of War Militarized Interstate Dispute Dataset, 1816–2001, and demonstrate that this variation across cases biases most analyses of conflict. Disputes are coded using two logics—the familiar state-to-state militarized action represents one case while the second relies on sponsor governments to protest state targeting of private citizens. We show that the latter introduces additional measurement bias and does not match well the original conceptualization of what constituted a dispute. The protest-dependent cases are caused by different processes, and omitting them from analyses provides truer estimates of the effects of most conflict predictors. We find that previous controls for heterogeneity in the dispute data—such as using fatal militarized interstate disputes only—substantially underestimates the dangerous effects of contiguity and the pacifying effects of regime similarity. We also show that governments are seldom willing to risk militarized conflict for private citizens during these unique cases. We provide a list of the protest-dependent cases for future conflict analyses.
