Post-Doctoral Researcher & Lecturer

Jan Menzner

I am a political scientist at Humboldt-Universität zu Berlin, where I work as a postdoctoral researcher and lecturer at Prof. Hanna Schwander’s Chair of Political Sociology and Social Policy. Since July 2025, I also serve as Acting Managing Director of the Berlin Graduate School of Sciences.

I see climate change as the defining political challenge of our time. In my dissertation and beyond, I thus study how it reshapes citizens’ relationship with democracy: whether climate concern erodes democratic satisfaction, whether both climate advocates and skeptics would bend democratic rules for their cause, and how experiencing heat or water restrictions shapes their view of the state.

My work has appeared in the Journal of European Public Policy, Politics & Governance and German Politics, among others (see all publications or my full CV), and further manuscripts are currently under review. I am always open to collaboration (see my ongoing projects).

National, Partisan or Ideological Biases? How EU Officials’ Characteristics can Influence Infringement Proceeding Outcomes

Menzner, J. and J. Lattmann

Journal of European Public Policy

Abstract

Infringement proceedings serve as a key legal mechanism through which the European Union (EU) enforces compliance with common laws among its member states. This article, for the first time, examines how the nationality and partisanship of EU officials influence outcomes of these proceedings. We argue that Commissioners and Directors-General face a principal–agent dilemma, as they simultaneously act as EU officials and as nationals of their home countries. We expect that infringement proceedings are less likely to escalate when they are overseen by EU officials who share the nationality of the member state under investigation. We further posit that officials’ partisan affiliations and ideological leaning may shape the outcomes of such cases. Using a novel dataset combining roughly 19.000 infringement proceedings between 2002 and 2020 with information about the responsible officials, we find evidence of a nationality bias, however, only among Commissioners. By contrast, we find no indication of bias linked to ideology or partisanship.

The Underlying Structure of Political Support

Menzner, J. and D. Schweizer

Politics & Governance

Abstract

Contemporary politics is marked by concerns about declining citizen satisfaction with democracy, falling political trust, and weakening democratic support. Scholars in this field often rely on the concept of political support but use its indicators interchangeably or inconsistently. Meanwhile, despite its relevance for democratic resilience, studies on its underlying structure remain scarce. Drawing on the foundational work of Easton and Norris, we derive expectations about the dimensionality of political support and the interplay among its various indicators. We test these expectations using factor analysis, item response theory models, random intercept cross‐lagged panel models, and first‐difference models applied to 29 waves of the German Longitudinal Election Study panel. As expected, specific support fluctuates substantially, whereas diffuse support is more stable, even though recent data show small declines in multiple indicators. Our results indicate that political support indicators form a one‐dimensional latent trait. Along this trait, specific evaluations, like satisfaction with the government, differentiate respondents at higher levels of support, whereas more diffuse attitudes, such as institutional trust, best distinguish between those with below‐average support. Longitudinal analyses reveal no evidence that changes in specific support systematically precede changes in diffuse support. Instead, changes in any indicator tend to predict subsequent changes in others, indicating self‐reinforcing dynamics. Finally, first‐difference models offer limited support for a buffering “reservoir of goodwill.” Prior levels of specific support neither amplify nor mitigate the effects of subsequent changes on more diffuse indicators. Beyond structural insights, our item response theory results provide important practical guidance for researchers when deciding between political support indicators.

The Importance of Descriptive Representation & Cue-Taking in Free List Local Elections

Menzner, J., C. Schmid and L. Rettig

German Politics

Abstract

With this study, we add to the literature on cue-taking and descriptive representation by focusing on a local, low-information context. Specifically, we empirically analyse voting patterns in the 2024 municipal elections in Mannheim, Germany. In this election, a free-list ballot design allowed voters to distribute 48 votes among 508 candidates of multiple parties, making it an ideal case to study these prominent theories of vote allocation. First, we show that party affiliation, ballot position, and incumbency significantly predict vote totals as expected. Ballot cues indicating candidates’ occupations and (to a limited extent) their gender additionally affect electoral outcomes. These findings complement previous experimental studies on ballot cues with observational research to better understand voter decision-making in complex real-world electoral settings. Using multilevel models, we further uncover a strong relevance of (geographical) representation and a home-district advantage in particular: Candidates receive about two-hundred per cent more votes in their own residential districts compared to their results in other districts. They also achieve substantially better results in districts with similar geographic location as their own. Lastly, voter age dynamics suggest that candidates benefit electorally when their age aligns with the demographic profile of the respective district.

Securing Moral Authority: A Cross-National Analysis of Protestant Engagement in the Implementation of Morality Policies in Western Europe

Mettang, O., E.-M. Euchner, L. Fischer and J. Menzner

VOLUNTAS

Abstract

Churches have a hard time defending their moral values in the political sphere of an ever more secular and liberal Western Europe. A largely neglected means of navigating this crisis is through the Church’s role as a charitable provider during the implementation of morality policies. This paper examines this type of church involvement from a cross-national and cross-sectoral perspective. We describe the activities of Protestant churches in four morality policy areas in three European countries: Germany, England, and Denmark. The variation in religious engagement observed in these areas and countries appear to be driven by the churches’ room to maneuver and their policy congruence with state goals, whereas governance capacities are secondary. Thus, the provision of social services can still serve as a means by which Protestant churches can exert moral authority, especially if these social services are related to moral issues.

The Potential of Open Lists for the Election of Women to the German Bundestag. Results of a Survey Experiment

Rudolph, L., Däubler, T. and J. Menzner

Politische Vierteljahresschrift  ·  1st Prize, Fritz-Thyssen-Foundation Award (2022)

Abstract

Women are underrepresented in the German parliament (Bundestag), especially in parties in and to the right of the political center. Gender quotas are frequently discussed as a remedy, but they infringe on the liberties of parties, candidates, and voters. In contrast, open lists receive little attention, although they would avoid these constitutional issues. Therefore, we examine how many German voters – overall and by party – would choose female candidates from open lists. Theoretically, we expect that female voters in particular, voters of left-leaning parties, and citizens for whom gender equality is a salient topic would support female politicians. We also expect that voters would tend to even out lists that were characterized by gender imbalance. Our research design utilized an online survey-embedded experiment (N = 2.640) with a quota-representative sample of eligible voters. Participants chose between lists of the parties represented in parliament, with four fictitious candidates each. The share of women (25 to 75 %) and the list type (closed vs open) were randomized. We find that both female and male voters consider the sex of the candidate, in line with the theoretical expectations. Our results suggest that female candidates would hardly be discriminated against overall, with some exceptions in specific subgroups (male voters of the Free Democratic Party, female voters of the Alternative for Germany). This article shows that open lists enable citizens to cast preference votes in support of gender equality and that this opportunity is indeed seized. Across parties, voters also level out unequal lists. Therefore, the electoral reform debate should pay more attention to the potential of open lists.

Subjective Freedom of Speech: Why Do Citizens Think They Cannot Speak Freely?

Menzner, J. and R. Traunmüller

Politische Vierteljahresschrift

Abstract

We provide the first systematic research into the origins of subjective freedom of speech in Germany. Relying on the GLES 2021 Cross-Section Pre-Election Survey, which includes a newly designed survey item on subjective freedom of speech, we evaluate a whole range of plausible candidate hypotheses. First, we contribute to cumulative research by testing the explanatory factors in Gibson (1993)—citizens’ social class, their political involvement and political preferences, and their personality dispositions—for the German case. Second, we move beyond the state of the art and test three new hypotheses that reflect more recent political developments and arguments in the free speech debate: the role of social media, increasing political and social polarization, and the rise of populism. Importantly, all hypothesis tests reported in this paper have been preregistered prior to data collection. Our results reveal that three explanatory factors are significantly, consistently, and substantively related to subjective free speech in Germany: political preferences, populist attitudes, and identification with the Alternative for Germany party.

Citizens’ Two-Sided Demand for Undemocratic Climate Governance R&R

Abstract

Citizens’ commitment to democratic norms is often conditional and instrumental. Especially under conditions of heightened polarization, many are willing to bypass norms for preferred political outcomes. I study this dynamic in a crucial, ideologically and affectively polarized, yet understudied case: climate change. Using original survey data from Germany (N = 2,101), I show that stronger preferences – whether for or against climate action – are robustly correlated with support for abstract and specific non-democratic governance aiding those preferences. This includes, for example, restricting climate activism, ignoring pro-climate action court rulings, and censoring climate change denial. Addressing concerns about ‘staged’ democrats, I additionally use two original list experiments to uncover support for non-democratic governance that respondents might hide due to strong social norms for democracy. The experiments reveal ‘true’ support for undemocratic climate action (prevention) by about 35 (39)% of citizens. Especially climate action skeptics tend not to disclose their non-democratic attitudes openly. This study thus contributes empirical insights to three closely related debates: on democratic resilience under polarization, on the political conflict over climate action, and on the concealment of undemocratic preferences. I show that policy attitudes, irrespective of their direction, can motivate instrumental norm trade-offs on both sides of a strongly polarized cleavage, offer the first joint account of both sides of the climate divide’s democratic commitment, and provide new evidence for ‘staged democrats’ who conceal authoritarian preferences behind public support for democracy. Recognizing these dynamics is crucial for protecting democratic commitments amid intensifying polarized conflict.

Not Simply Simplified: Systematic Issue Emphasis in Easy-Read Manifestos R&R

with Lukas Isermann & Julius Diener

Abstract

In this paper we demonstrate that political parties in Germany systematically alter their issue emphasis in easy-read manifestos (ERMs) compared to regular manifestos. We argue parties face incentives to target ERMs’ distinct audience – citizens with disabilities and those struggling with complex language – by emphasizing issues most salient to this electorate. Applying natural language processing on 74 ERMs between 2009 and 2025 from five parties we find substantial distortions in communicated political priorities. Welfare-related issues are, on average, overemphasized by 9 percentage points, while economic issues are de-emphasized. These differences are generally stronger among left-leaning parties. Furthermore, parties address ERMs’ target audience with group-based appeals nearly four times more frequently in ERMs than in their regular manifestos. We corroborate parties’ contribution to this mismatch through qualitative questionnaires sent to easy-language translation agencies, which confirm that parties are directly and extensively involved in translating ERMs. Our study adds to the literature on strategic issue emphasis by identifying targeting behavior in a previously unstudied form of communication. We also show that NLP methods can be applied to less prominent text types like easy-read language. Finally, our findings raise important questions about political inclusivity, as targeting may compromise ERMs’ role as neutral empowerment tools.

The Price of Privileges: Corporate Tax Secrets and Democratic Satisfaction

with Zora Jochim

Abstract

Can a financial scandal in another country shake citizens’ political support at home? We examine the 2014 LuxLeaks, which exposed secret tax deals between Luxembourg and more than 340 multinational firms. The leak broke during fieldwork for Round 7 of the European Social Survey, creating a natural experiment in Germany, the Netherlands, Belgium, and Switzerland, which we exploit using an Unexpected Event during Survey Design. Its peculiarities make this an instructive case: the deals were legal, and only directly implicated Luxembourgish politicians. However, the involvement of firms from 82 countries and Jean-Claude Juncker, who had become European Commission President days earlier, linked the scandal to politics across Europe. Pooled results show that the disclosure significantly lowered satisfaction with democracy (SWD). Our finding holds across control strategies, estimators, and bandwidths. Robustness checks speak against time trends, cyclical patterns, and a general shift in public mood. Respondents in Germany, whose major firms featured prominently in the leaks, drive the decline in SWD and simultaneously became less satisfied with their economy. Dutch respondents show a smaller, non-significant drop in SWD but a sharper loss of trust in national political institutions. Belgian and Swiss respondents barely reacted. Our findings overall support dysfunctionalist accounts of scandal: When a scandal is salient and can be tied to domestic institutions or actors, even legal practices exposed abroad can causally erode political support. The magnitude and shape of the backlash depend on context, such as involvement of domestic firms, media reporting, and how national governments respond.

More Concerned, Less Satisfied? Climate Concern and Democratic Satisfaction Within and Between Citizens

with David Schweizer

Abstract

Concern about climate change has risen sharply across Europe, yet its democratic implications remain understudied. Drawing on the idea of a state–citizen contract that extends beyond material prosperity to citizens’ well-being, we argue that rising climate concern could negatively impact citizens’ satisfaction with democracy (SWD). Cross-sectional data, however, may mask this relationship, as climate concern is most prevalent among groups that are more satisfied with democracy to begin with. Using four waves of the German Socio-Economic Panel (2010–2021; 65,409 observations) and random-effects-within-between models, we uncover exactly this divergence. Between individuals, higher average climate concern is associated with higher SWD. Within individuals, by contrast, increases in climate concern are robustly associated with declines in SWD. By 2020/21, this within-person association exceeds that of financial concern and approaches those of concern about immigration and crime. It is most pronounced where climate change is arguably most salient: in the most recent data, among post-materialists, and among stable Green partisans. Our analysis thus recasts climate concern as a previously overlooked correlate of democratic dissatisfaction, hidden in cross-sectional data and concentrated among citizens whom democracies could otherwise count among their strongest supporters. As climate impacts intensify, unaddressed concern may become a growing challenge for democratic support, making credible government climate action not only an environmental but also a democratic imperative.

Everyone Loves Democracy, But Who Wants to Protect It? Examining Support for Militant Democracy

with Luke Shuttleworth & Hanna Schwander

Abstract

Democratic backsliding has reignited debates over militant democracy, i.e. pre-emptive measures to keep undemocratic actors out of power. While existing research examines the design and effectiveness of measures such as proscription and employment bans, we know little about citizens’ support for such measures. Yet democratic resilience depends not only on institutions and elites but also on citizens’ willingness to defend democracy. We make two arguments. First, when state authorities officially designate political organisations as extremist, this acts as an institutional cue that increases support for pre-emptive measures, particularly among citizens with high levels of institutional trust. Second, support is not always principled but may instead reflect instrumental reasoning, with citizens more willing to endorse restrictions against ideological opponents than against ideologically proximate actors. We evaluate these claims with data from an original survey of ≈ 4,000 respondents in Germany. We also introduce and validate the first measure of citizens’ support for militant democracy. We show that support for pre-emptive measures reflects both institutional legitimacy and ideological bias: official extremist designations correlate with support, particularly among high-trust citizens, while individuals remain more willing to target ideological opponents than allied groups. Our findings suggest that the legitimacy of militant democracy ultimately depends on the credibility of the institutions implementing it.

Lonely on the Land: Surplus Males and Support for the Radical Right

with Mark Kayser, Arndt Leininger, Dani Sandu, Hanna Schwander & Thomas Tichelbäcker

Abstract

Many rural areas in developed democracies face a surplus of unattached men, as women of reproductive age have disproportionately moved away. We show that this demographic imbalance is positively associated with radical right vote shares in Europe and in Germany and provide individual-level evidence for a mechanism beyond composition. We argue that difficulties finding a partner during family-formation years shift men’s political behavior toward the radical right. Survey data from Germany show that a higher municipal male surplus predicts greater support for the radical right AfD among men but not women. Moreover, men respond specifically to gender imbalance within their age group. These effects concentrate among those aged 18–44. Further, those who report greater difficulty finding a partner are more likely to hold xenophobic attitudes and support the AfD. Gender imbalances may thus reshape politics by altering men’s political preferences, not just their share of the electorate.

Uncovering Uneven Class Awareness: A Heteroskedastic Regression Approach to Subjective Class Placement Part of special issue

with Franziska Veit

Abstract

Social class is central to contemporary debates on political identity and attitude formation in Germany. But objective indicators of class often diverge from subjective perceptions of class membership. We examine this divergence and possible consequences by modeling differences in error variance when predicting subjective class perceptions and left-right self-placement from three standard objective class indicators – education, income, and occupational prestige – through a heteroskedastic maximum likelihood estimator. Using cross-sectional survey data from Germany (2021/2022; N = 8,328), we first show that these markers predict subjective class more precisely among individuals with a higher education, those with higher life satisfaction and a sense of receiving their fair share in life. This pattern further extends to political attitudes: objective class is similarly less precisely predictive of left-right self-placement among citizens with lower incomes and those dissatisfied with what they receive in life. Together, these results speak towards obstacles of mobilizing dissatisfied lower-class citizens around shared material interests: It is exactly those citizens for whom objective material circumstances translate least coherently into shared political attitudes and class identities. Additionally, citizens embedded in homogeneous networks show a noisier link between class position and political stance. Those with more diverse social contacts instead possibly benefit from cross-cutting exposure that keeps political views more closely calibrated to material circumstance. More broadly, our analysis further suggests that treating subjective and objective class as interchangeable introduces systematic modeling error, and illustrates the usefulness of treating heteroskedasticity as informative rather than a nuisance for political science research in general.
