Partisan actors in the US have recently politicized trust in elections. In combination with partisan polarization, politicized election administration could undermine the peaceful transfer of power following elections. Can messaging about trust in elections break through partisan polarization? Partnering with election officials from Los Angeles County, Colorado, Georgia, and Texas, we conducted messaging experiments with nearly 8,500 Americans following the 2022 US midterm elections. We find that state and local election officials can be strongly effective at increasing trust in their own state elections. Our estimate suggests that one 30-second official message increases trust in elections by about one-fifth of the pre-treatment difference between Democrats and Republicans. Additionally, videos explaining protections on election integrity in Arizona and Virginia increase trust in elections outside the respondents’ own states. Our results suggest that election officials can break through partisan politics and play an important role in rebuilding trust in the democratic process.

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.

We present results from a pre-registered, well-powered $(N \gt 3,000,000)$ text message get-out-the-vote (GOTV) experiment, conducted during the 2019 European Parliament election in Sweden. Our findings suggest that a simple text message increases the likelihood of voting by 0.3 percentage points. Half of this effect spills over to untreated household members while workplace spillovers are near zero. Subsequent analysis reveals that the direct treatment effect is noticeably stronger among individuals with below-average voting propensities. Interestingly, within this same group, the household spillovers are significantly negative. We speculate and provide some indirect evidence, that these negative spillover effects may stem from the text message reminder influencing the behaviour of voters already motivated to vote. Above all, we propose that an increase in early voting, as opposed to voting on Election Day, among treated individuals may weaken the mechanisms thought to explain spillover effects since voters are less likely to bring their family members with them when voting early.

A perennial issue of survey research is that some participants do not answer all questions. Interactive follow-up requests are a novel approach to this problem. However, research on their effectiveness is scarce. I present the most comprehensive study yet on the effects of interactive requests on item non-responses. Theoretically, I outline different pathways whereby follow-up requests may effectively increase response rates and improve data quality: reminding, motivating, instructing, monitoring, and sanctioning. To test my hypothesis that interactive requests increase item response rates, I conducted an online survey experiment in 2021 on diverse samples of around 3,100 respondents in ten countries worldwide. I find that follow-up requests generally increase response rates, although effects vary by country. Depending on the question and survey design, interactive requests reduce item non-responses by up to 47 per cent across countries, while not adversely affecting data quality. I thus recommend response requests to increase survey data efficiency.

In the study of politics, many theoretical accounts assume that we are experiencing a ‘crisis of democracy’, with declining levels of political trust. While some empirical studies support this account, others disagree and report ‘trendless fluctuations’. We argue that these empirical ambiguities are based on analytical confusion: whether trust is declining depends on the institution, country, and period in question. We clarify these issues and apply our framework to an empirical analysis that is unprecedented in geographic and temporal scope: we apply Bayesian dynamic latent trait models to uncover underlying trends in data on trust in six institutions collated from 3,377 surveys conducted by 50 projects in 143 countries between 1958 and 2019. We identify important differences between countries and regions, but globally we find that trust in representative institutions has generally been declining in recent decades, whereas trust in ‘implementing’ institutions has been stable or rising.

How elected representatives think about public opinion affects the degree to which policies are congruent with the public’s policy preferences. This is especially true for politicians occupying leadership positions, their perceptions matter even more. Extant work concluded that politicians in general do not exhibit a high perceptual accuracy, but direct evidence of the relative accuracy of leaders’ perceptions of public opinion is missing. Drawing on surveys among politicians and citizens in four countries, this study examines the accuracy of the public opinion perceptions of leaders and backbenchers. Irrespective of how leadership is defined and operationalized – executive or party leadership, formal or informal leadership, current or past leadership – we find low perceptual accuracy levels among leading politicians. Compared to backbenchers, and although politicians themselves consider leaders to have a special nose for public opinion, leading politicians do not possess a special public opinion rating skill.

Although far-right insurrections often catch worldwide attention, little is known about whether and how these autocratization events affect other countries. This article studies the spillover of a prototype of such coup attempts – the January 6th Capitol insurrection. I argue that a far-right insurrection abroad can trigger a transnational learning process, which increases the salience of the far-right’s anti-democratic potential. Consequently, due to shaming and changes in voting calculus, citizens are less likely to support a domestic far-right party. To test this expectation, I use two panel datasets in Western Europe fielded amid the Capitol insurrection. Both analyses show that the expressed support for domestic far-right parties decreased after this autocratization event. I discuss how these findings enrich the literature on autocratization, the far-right, and transnational learning.

The participants in deliberative mini-publics are typically randomly selected; therefore, mini-publics are often marketed as representative of the wider population. However, in practice, mini-publics are unlikely to be fully representative due to their small size and non-response bias. I report the results of a pre-registered survey experiment designed to assess the implications of deviations from statistical representativeness for citizens’ legitimacy beliefs (N = 1,308). Consistent with prior research, I find that the involvement of a mini-public in democratic decision-making can lead to substantial increases in perceptions of process legitimacy; however, even minor biases in the composition of mini-publics substantially decrease those gains while larger biases can wipe them out entirely. The results of this study temper hopes that mini-publics offer an easy fix to perceptions of low democratic legitimacy.

Why do US voters allow politicians to hold the country’s economy hostage during debt ceiling negotiations? In this research note, we argue that ignorance and uncertainty over the consequences of a debt ceiling breach play a nontrivial role in public support for hard-line negotiating positions. In a pre-registered survey experiment, two weeks before the June 2023 deadline to raise the US debt ceiling, we show that providing credible information about the consequences of default increases support for concessions among both Democrats and Republicans. Further, more certain information about the consequences of a debt ceiling breach has a larger effect than less-certain information suggesting that the unpredictable consequences of the crisis also help explain voter reluctance to accept concessions. The findings have implications for understanding debt ceiling negotiations and other crisis bargaining situations where the public serves as a relevant third party.

Turnout buying is a mainstay of machine politics. Despite strong theory that selective incentives should spur turnout, meta-analyses of empirical studies show no effect, thus making machine politics seem irrational and unsustainable. I argue that the apparent failure of turnout buying is an artefact of common measurement decisions in experimental and observational research that lump together turnout buying, abstention buying, and vote-choice buying. Data generated using these compound measures include countervailing and null effects that drive estimates of the effects of each strategy toward zero. I show that machines have incentives to diversify their strategies enough to make compound measures substantially underestimate the impact of turnout buying. I propose simple alternative measurement approaches and show how they perform using new survey data and a constituency-level analysis of machine strategy in Mexico. Findings close the gap between theory and facts and reaffirm the rationality of machine politics.

Does shaming human rights violators shape attitudes at home? A growing literature studies the effect of shaming on public attitudes in the target state, but far less is known about its effect in countries initiating the criticism – that is the shamers. In this article, I theorize that when governments shame human rights violators they shape both government approval and human rights attitudes at home. Utilizing two US-based survey experiments, I demonstrate that by shaming foreign countries, governments can improve their image at home and virtue signal their dedication to human rights. At the same time, shaming can modestly shape tolerance towards certain domestic human rights violations. I consider the generalizability of my results through comprehensive supplementary analyses, where experimental insights are corroborated with cross-national observational data. Overall, my findings can provide valuable insight into governments’ incentives to engage in foreign criticism.

Liberals experience more distress than conservatives. Why? We offer a novel explanation, the social support hypothesis. Maintaining social support and avoiding exclusion are basic human motivations, but people differ in their sensitivity to the threat of social exclusion. Among people high in the personality trait neuroticism, exclusion easily triggers feelings of vulnerability and neediness. The social support hypothesis translates this to politics. Concerned with their own vulnerability, we find that neurotic people prefer policies of care – social welfare and redistribution – but not other left-wing policies. Specifically, it is anxiety – the facet of neuroticism tapping sensitivity to social threats – that drives this link. And it is only for people experiencing exclusion that anxiety predicts support for social welfare. Our results come from two experiments and four representative surveys across two continents. They help to resolve the puzzle of liberal distress while providing a new template for research on personality and politics.

Affluent citizens commonly record higher election turnout than less affluent citizens. Yet, the causal effect of affluence on voter turnout remains poorly understood. In this article, we rely on Norwegian administrative data to estimate the impact of random, exogenous shocks in (unearned) income on individual-level voter turnout. Exploiting the random timing and size of lottery wins for identification, our main findings suggest that a lottery windfall in the years just before an election boosts individuals’ turnout probability by 1.6 to 1.9 percentage points. Crucially, these point estimates reflect only a small share of turnout differences observed across the income distribution. Hence, our findings strongly suggest that most of the commonly observed positive income-turnout associations do not reflect a causal relationship.

This paper develops an account of freedom of expression by drawing lessons from the strategic logic of China’s censorship regime. It argues that freedom of expression helps build the common knowledge needed for overcoming coordination problems and is, thus, a source of collective power. However, realizing the full empowering potential of freedom of expression requires supplementing it with (a) public sources of information that are reliable, trusted, and democratically accountable and (b) measures that will provide citizens with equal opportunity to speak and be heard in ways that will enable them to contribute to their society’s stock of common knowledge.
