  • Artificial intelligence in government

    Open Access•Alexander Wuttke, Andreas Jungherr et al.•ARTICLE•Journal of European Public Policy•2026

    The use of Artificial Intelligence (AI) in public administration is expanding rapidly. While AI promises greater efficiency and responsiveness, its integration into government and administration raises concerns about fairness, transparency, and accountability. Relying on principal-agent theory and related frameworks, we conceptualize AI adoption as a case of algorithmic delegation involving power and information asymmetries. This perspective high…

  • The politics of artificial intelligence alignment

    Open Access•Adrian Rauchfleisch, Andreas Jungherr•ARTICLE•New Media & Society•2026

    This study tests how a prominent artificial intelligence (AI) product failure influences public attitudes, focusing on Google Gemini’s generation of controversial images. Drawing on the AI alignment literature, we distinguish three moderation goals that differ in how far they depart from data-driven outputs: safety, bias mitigation, and aspirational imaginaries. We use focusing events research to explain how controversies make governance question…

  • Artificial Intelligence in Election Campaigns

    Open Access•Andreas Jungherr, Adrian Rauchfleisch et al.•ARTICLE•Political Communication•2026•References: 13

    As political parties around the world experiment with Artificial Intelligence (AI) in election campaigns, concerns about deception and manipulation are rising. This article examines how the public reacts to different uses of AI in elections and the potential consequences for party evaluations and regulatory preferences. Across three preregistered studies with over 7600 American respondents, we identify three categories of AI use: campaign operati…

  • Winning and losing with Artificial Intelligence

    Open Access•Adrian Rauchfleisch, Joshua Philip Suarez et al.•ARTICLE•Telematics and Informatics•2025

    Public AI launches serve as focusing events, sparking societal negotiation of meaning. • People negotiate meaning of AI based on their economic interests and cultural values. • Technical occupations adopt AI early positively; writing jobs join later, skeptically. • Individualism drives early engagement and more negative stances toward ChatGPT. • Aggregate stance shifts stem from speaker mix changes, not individual opinion change. Public product l…

  • Public Opinion on the Politics of AI Alignment

    Open Access•Andreas Jungherr, Adrian Rauchfleisch•ARTICLE•Social Media + Society•2025•References: 6

    Recent advances in generative AI have raised public awareness, shaping expectations and concerns about their societal implications. Central to these debates is the question of AI alignment—how well AI systems meet public expectations regarding safety, fairness, and social values. However, little is known about what people expect from AI-enabled systems and how these expectations differ across national contexts. We present evidence from two survey…

  • Artificial Intelligence in deliberation

    Open Access•Andreas Jungherr, Adrian Rauchfleisch•ARTICLE•Government Information Quarterly•2025•References: 5

    Digital deliberation has expanded democratic participation, yet challenges remain. This includes processing information at scale, moderating discussions, fact-checking, or attracting people to participate. Recent advances in artificial intelligence (AI) offer potential solutions, but public perceptions of AI's role in deliberation remain underexplored. Beyond efficiency, democratic deliberation is about voice and recognition. If AI is integrated …

  • Explaining public preferences for regulating Artificial Intelligence in election campaigns

    Open Access•Adrian Rauchfleisch, Andreas Jungherr et al.•ARTICLE•Telecommunications Policy•2025•References: 30

    The increasing use of Artificial Intelligence (AI) in election campaigns, such as AI-generated political ads, automated messaging, and the widespread availability of AI-assisted photorealistic content, is transforming political communication. This new era of AI-enabled election campaigns presents regulatory challenges for digital media ecosystems, prompting calls for an updated governance framework. While research has begun mapping AI's role in d…

  • Blame and obligation

    Open Access•Adrian Rauchfleisch, Andreas Jungherr•ARTICLE•Policy & Internet•2024

    Disinformation concerns have heightened the importance of regulating content and speech in digital communication environments. Perceived risks have led to widespread public support for stricter control measures, even at the expense of individual speech rights. To better understand these preferences in the US context, we investigate public attitudes regarding blame for and obligation to address digital disinformation by drawing on political ideolo…

  • Negative Downstream Effects of Alarmist Disinformation Discourse

    Open Access•Andreas Jungherr, Adrian Rauchfleisch•ARTICLE•Political Behavior•2024•Cited by: 8•References: 53

    The threat of disinformation features strongly in public discourse, but scientific findings remain conflicted about disinformation effects and reach. Accordingly, indiscriminate warnings about disinformation risk overestimating its effects and associated dangers. Balanced accounts that document the presence of digital disinformation while accounting for empirically established limits offer a promising alternative. In a preregistered experiment, U…

  • Artificial intelligence and the public arena

    Open Access•Andreas Jungherr, Ralph Schroeder•ARTICLE•Communication Theory•2023•Cited by: 12•References: 10

    The public arena relies on artificial intelligence (AI) to ever greater degrees. Media structures hosting the public arena—such as Facebook, TikTok, Twitter, and YouTube—increasingly rely on AI-enabled applications to shape information environments, autonomously generate content, and communicate with people. These applications affect the public arena’s functions: make society visible to itself and provide spaces for the formation of publics and c…

  • Artificial Intelligence and Democracy

    Open Access•Andreas Jungherr•ARTICLE•Social Media + Society•2023•Cited by: 10•References: 94

    The success and widespread deployment of artificial intelligence (AI) have raised awareness of the technology's economic, social, and political consequences. Each new step in the development and application of AI is accompanied by speculations about a supposedly imminent but largely fictional artificial general intelligence (AGI) with (super-)human capacities, as seen in the unfolding discourse about capabilities and impact of large language mode…

  • The Extended Reach of Game Engine Companies

    Open Access•Andreas Jungherr, Damien B Schlarb•ARTICLE•Social Media + Society•2022•Cited by: 2•References: 28

    Game engines have come to feature in areas well beyond gaming-such as architecture, artificial intelligence, manufacturing, public planning, and film and television production. Accordingly, companies developing, providing, and maintaining game engines-such as Epic Games or Unity Technologies-are set to become influential actors in all social and economic arenas that start to rely on game engines for the provision of software or services. This mak…

  • A Source Like Any Other? Field and Survey Experiment Evidence on How Interest Groups Shape Public Opinion

    Open Access•Andreas Jungherr, Alexander Wuttke et al.•ARTICLE•Journal of Communication•2021

    Interest groups increasingly communicate with the public, yet we know little about how effective they are in shaping opinions. Since interest groups differ from other public communicators, we propose a theory of interest group persuasion. Interest groups typically have a low public profile, and so most people are unlikely to have strong attitudes regarding them. Source-related predispositions, such as credibility assessments, are therefore less r…

  • Populist Supporters on Reddit

    Open Access•Andreas Jungherr, Oliver Posegga et al.•ARTICLE•Social Science Computer Review•2021•Cited by: 4•References: 4

    The international rise of populism has been attributed, in part, to digital media. These media allow the backers of populists to share and distribute information independent of traditional media organizations or elites and offer communication spaces in which they can support each other and strengthen communal ties irrespective of their societal standing. Can we identify these functions in distinct usage patterns of digital media by supporters of …

    The challenge of disentangling political communication processes and their effects has grown with the complexity of the new political information environment. But so have scientists' toolsets and capacities to better study and understand them. We map the challenges and opportunities of developing, synthesizing, and applying data collection and analysis techniques relying primarily on computational methods and tools to answer substantive theory-dr…

  • Disinformation and the Structural Transformations of the Public Arena

    Open Access•Andreas Jungherr, Ralph Schroeder•ARTICLE•Social Media + Society•2021•Cited by: 12•References: 68

    Current debate is dominated by fears of the threats of digital technology for democracy. One typical example is the perceived threats of malicious actors promoting disinformation through digital channels to sow confusion and exacerbate political divisions. The prominence of the threat of digital disinformation in the public imagination, however, is not supported by empirical findings which instead indicate that disinformation is a limited problem…

  • Retooling Politics

    Open Access•Andreas Jungherr, Gonzalo Rivero et al.•BOOK•Retooling Politics•2020

    Donald Trump, the Arab Spring, Brexit: digital media have provided political actors and citizens with new tools to engage in politics. These tools are now routinely used by activists, candidates, non-governmental organizations, and parties to inform, mobilize, and persuade people. But what are the effects of this retooling of politics? Do digital media empower the powerless or are they breaking democracy? Have these new tools and practices fundam…

    Contemporary media systems are in transition. The constellation of organizations, groups, and individuals contributing information to national and international news flows has changed as a result of the digital transformation.

    As political parties expand opportunities for intraparty participation, understanding the effects of participatory events on party actors becomes ever more important. In this study, we investigate the consequences of an intraparty referendum in a state branch of Germany’s Christian Democratic Union on beliefs and attitudes of party members. We use longitudinal survey data bracketing a nonbinding issue referendum on the party’s stance on same-sex …

  • Digital Media and the Surge of Political Outsiders

    Open Access•Andreas Jungherr, Ralph Schroeder et al.•ARTICLE•Social Media + Society•2019•Cited by: 19•References: 53

    There has been a recent surge of political actors and groups challenging the legitimacy of established political institutions and mass media. We argue that this wave is no accident; rather, it is driven by digital media. Digital media allow outside challengers to route around social institutions that structure political discourse, such as parties and legacy media, which have previously held a monopoly on political coordination and information dis…

Contemporary trade agreements, however, often reach beyond trade in the narrow sense. Consequently, factors unrelated to free trade may affect citizens’ evaluations of these agreements. We propose a model of attitude formation toward specific trade agreements that …

    The continuously growing use of digital services has provided social scientists with an expanding reservoir of data, potentially holding valuable insights into human behavior and social systems. This has often been associated with the terms “big data” and “computational social science.” Using such data, social scientists have argued, will enable us to better understand social, political, and economic life. Yet this new data type comes not only wi…

    Many studies use the same factors to explain attitudes toward specific trade agreements and attitudes toward the principle of free trade and thus treat both objects as interchangeable. Contemporary trade agreements, however, often reach beyond trade in the narrow sense. Consequently, factors unrelated to free trade may affect citizens’ evaluations of these agreements. We propose a model of attitude formation toward specific trade agreements that …

    Contemporary media systems are in transition. The constellation of organizations, groups, and individuals contributing information to national and international news flows has changed as a result of the digital transformation. The “hybrid media system” has proven to be one of the most instructive concepts addressing this change. Its focus on the mutually dependent interconnections between various types of media organizations, actors, and publics …

  • More than opinion expression

    Open Access•Alexander Wuttke, Andreas Jungherr et al.•ARTICLE•Party Politics•2019•Cited by: 14•References: 32

    As political parties expand opportunities for intraparty participation, understanding the effects of participatory events on party actors becomes ever more important. In this study, we investigate the consequences of an intraparty referendum in a state branch of Germany’s Christian Democratic Union on beliefs and attitudes of party members. We use longitudinal survey data bracketing a nonbinding issue referendum on the party’s stance on same-sex …

  • Digital Media and the Surge of Political Outsiders

    Open Access•Andreas Jungherr, Ralph Schroeder et al.•ARTICLE•Social Media + Society•2019•Cited by: 19•References: 53

    There has been a recent surge of political actors and groups challenging the legitimacy of established political institutions and mass media. We argue that this wave is no accident; rather, it is driven by digital media. Digital media allow outside challengers to route around social institutions that structure political discourse, such as parties and legacy media, which have previously held a monopoly on political coordination and information dis…

  • Retooling Politics

    Open Access•Andreas Jungherr, Gonzalo Rivero et al.•BOOK•Retooling Politics•2020

    Donald Trump, the Arab Spring, Brexit: digital media have provided political actors and citizens with new tools to engage in politics. These tools are now routinely used by activists, candidates, non-governmental organizations, and parties to inform, mobilize, and persuade people. But what are the effects of this retooling of politics? Do digital media empower the powerless or are they breaking democracy? Have these new tools and practices fundam…

  • The Role of Flag Emoji in Online Political Communication

    Open Access•Ankit Kariryaa, Simon Rundé et al.•ARTICLE•Social Science Computer Review•2020•Cited by: 9•References: 13

    Flags are important national symbols that have transcended into the digital world with inclusion in the Unicode character set. Despite their significance, there is little information about their role in online communication. This article examines the role of flag emoji in political communication online by analyzing 640,676 tweets by the most important political parties and Members of Parliament in Germany and the United States. We find that natio…

  • A Source Like Any Other? Field and Survey Experiment Evidence on How Interest Groups Shape Public Opinion

    Open Access•Andreas Jungherr, Alexander Wuttke et al.•ARTICLE•Journal of Communication•2021

    Interest groups increasingly communicate with the public, yet we know little about how effective they are in shaping opinions. Since interest groups differ from other public communicators, we propose a theory of interest group persuasion. Interest groups typically have a low public profile, and so most people are unlikely to have strong attitudes regarding them. Source-related predispositions, such as credibility assessments, are therefore less r…

  • Populist Supporters on Reddit

    Open Access•Andreas Jungherr, Oliver Posegga et al.•ARTICLE•Social Science Computer Review•2021•Cited by: 4•References: 4

    The international rise of populism has been attributed, in part, to digital media. These media allow the backers of populists to share and distribute information independent of traditional media organizations or elites and offer communication spaces in which they can support each other and strengthen communal ties irrespective of their societal standing. Can we identify these functions in distinct usage patterns of digital media by supporters of …

  • Computational Social Science and the Study of Political Communication

    The challenge of disentangling political communication processes and their effects has grown with the complexity of the new political information environment. But so have scientists' toolsets and capacities to better study and understand them. We map the challenges and opportunities of developing, synthesizing, and applying data collection and analysis techniques relying primarily on computational methods and tools to answer substantive theory-dr…
