Elite Rhetoric and the Running Tally of Party-Group Linkages
Measuring Social and Political Identities in Social Media Self-Descriptions
Identities are fundamental to our understanding of social and political behavior, but are challenging to measure and are rarely observed in real-world settings. We introduce a method for measuring the identity-relevant aspects of brief self-descriptions regularly used online (e.g., on social media). Our approach combines the benefits of word embeddings for finding related identity terms with the ability of clustering algorithms to aggregate terms…
Partisan conflict in nonverbal communication
In multiparty systems, parties signal conflict through communication, yet standard approaches to measuring partisan conflict in communication consider only the verbal dimension. We expand the study of partisan conflict to the nonverbal dimension by developing a measure of conflict signaling based on variation in a speaker’s expressed emotional arousal, as indicated by changes in vocal pitch. We demonstrate our approach using comprehensive audio d…
Detecting pro-kremlin disinformation using large language models
A growing body of literature examines manipulative information by detecting political mis-/disinformation in text data. This line of research typically involves highly costly manual annotation of text for manual content analysis, and/or training and validating automated downstream approaches. We examine whether Large Language Models (LLMs) can detect pro-Kremlin disinformation about the war in Ukraine, focusing on the case of the downing of the c…
Losing Touch
The electoral ‘cost of governing’ is widely considered a law-like phenomenon. However, costs of governing are not limited to the electoral dimension. This paper highlights and documents an unappreciated nonelectoral cost of holding government office: diminished rhetorical simplicity. I argue that the functional demands of running government compel government members to speak less simply than is electorally optimal. I refer to this effect as 'the …
Reining in the Rascals
Challenger parties (i.e., parties without prior government experience) have transformed politics in Europe and beyond, some eventually joining governing coalitions. However, the process by which challenger parties gain access to power remains unclear. We argue that holding elected office in itself improves challenger parties’ chances of entering government. We find support for this expectation in cross-sectional, national-level data. To establish…

Do Violent Protests Affect Expressions of Party Identity? Evidence from the Capitol Insurrection
The insurrection at the United States Capitol on January 6, 2021, was the most dramatic contemporary manifestation of deep political polarization in the United States. Recent research shows that violent protests shape political behavior and attachments, but several questions remain unanswered. Using day-level panel data from a large sample of US social media users to track changes in the identities expressed in their Twitter biographies, we show …
Sheltering Populists? House Prices and the Support for Populist Parties
Populist parties, particularly from the right of the political spectrum, have sharply increased their electoral support in recent years, creating great media and scholarly interest. Existing work examining the economic underpinnings of populist support has focused on labor market shocks and the presence or absence of government compensation. In this paper we suggest that the housing market may have been as important as the labor market in definin…
When Does Accommodation Work? Electoral Effects of Mainstream Left Position Taking on Immigration
In many countries, right-wing populist parties have gained electoral support by attracting voters from mainstream left parties. This has prompted public and scholarly debate about whether mainstream left parties can regain political power by taking a more restrictive position on immigration, a so-called accommodation strategy. However, selection bias confounds observational estimates of the effectiveness of this strategy. This letter reports the …
Moral dilemmas and trust in leaders during a global health crisis
Trust in leaders is central to citizen compliance with public policies. One potential determinant of trust is how leaders resolve conflicts between utilitarian and non-utilitarian ethical principles in moral dilemmas. Past research suggests that utilitarian responses to dilemmas can both erode and enhance trust in leaders: sacrificing some people to save many others ('instrumental harm') reduces trust, while maximizing the welfare of everyone equ…
The Influence of Local Ethnic Diversity on Group-Centric Crime Attitudes
Several studies provide evidence of group-centric policy attitudes, that is, citizens evaluating policies based on linkages with visible social groups. The existing literature generally points to the role of media imagery, rhetoric and prominent political sponsors in driving group-centric attitudes. This article theorizes and tests an alternative source: exposure to rising local ethnic diversity. Focusing on the issue of crime, it first develops …
Ideological Asymmetry in the Reach of Pro-Russian Digital Disinformation to United States Audiences
Despite concerns about the effects of pro-Russian disinformation on Western public opinion, evidence of its reach remains scarce. We hypothesize that conservative individuals will be more likely than liberals to be potentially exposed to pro-Russian disinformation in digital networks. We evaluate the hypothesis using a large data set of U.S.-based Twitter users, testing how ideology is associated with disinformation about the 2014 crash of the MH…
Behavioral Dishonesty in the Public Sector
We investigate the usefulness of the dice game paradigm to public administration as a standardized way of measuring (dis)honesty among individuals, groups, and societies. Measures of dishonesty are key for the field’s progress in understanding individual, organizational, and societal differences in unethical behavior and corruption. We first describe the dice game paradigm and its advantages and then discuss a range of considerations for how to i…
When Do Citizens Respond Politically to the Local Economy? Evidence from Registry Data on Local Housing Markets
Recent studies of economic voting have focused on the role of the local economy, but with inconclusive results. We argue that while local economic conditions affect incumbent support on average, the importance of the local economy varies by citizens' interactions with it. More recent and frequent encounters with aspects of the local economy make those aspects more salient and, in turn, feature more prominently in evaluations of the incumbent gove…
Intergroup Bias in Parliamentary Rule Enforcement
Political actors are often assigned roles requiring them to enforce rules without giving in-groups special treatment. But are such institutional roles likely to be successful? Here, I exploit a special case of exogenously assigned intergroup relations: debates in the Danish Parliament, in which Parliament chairmen drawn from parliamentary parties enforce speaking time. Analyzing 5,756 speeches scraped from online transcripts, I provide evidence t…
Who benefits? Welfare chauvinism and national stereotypes
Cross-border welfare rights for citizens of European Union member states are intensely contested, yet there is limited research into voter opposition to such rights, sometimes denoted ‘welfare chauvinism’. We highlight an overlooked aspect in scholarly work: the role of stereotypes about beneficiaries of cross-border welfare. We present results from an original large-scale survey experiment (N=2525) among Swedish voters, randomizing exposure to c…
Computers, coders, and voters
Assigning political actors positions in ideological space is a task of key importance to political scientists. In this paper we compare estimates obtained using the automated Wordscores and Wordfish techniques, along with estimates from voters and the Comparative Manifesto Project (CMP), against expert placements. We estimate the positions of 254 manifestos across 33 elections in Germany and Denmark, two cases with very different textual data ava…
