As digital technologies have made their way into news production, allowing news organizations to measure audience behaviors and engagement in real-time, click-based and editorial goals, have become increasingly intertwined. Ongoing developments in algorithmic technologies allow editors to bring their audience into the newsroom using specialized too...

As chatbots are gaining more popularity than ever, they have recently been considered as interesting tools for survey administration in social science research. To explore this idea, we investigated the extent to which there are differences in response characteristics and data quality between a traditional, web-based survey and a conversational, ch...
Article
The platformised news environment affects audiences, challenges the news media’s role, and transforms the media ecosystem. Digital platform companies influence opinion formation and hence wield “opinion power,” a normatively and constitutionally rooted notion that captures the core of media power in democracy and substantiates why that power must b...

Data suggests that the majority of citizens in various countries came across ‘fake news’ during the COVID-19 pandemic. We test the relationship between perceived prevalence of misinformation and people’s worries about COVID-19. In Study 1, analyses of a survey across 17 countries indicate a positive association: perceptions of high prevalence of mi...

Political microtargeting is the subject of heated societal debate but not much is known about its effects, especially in non-US contexts. Microtargeting, used by political actors to send citizens tailored messages, could have the potential to overcome barriers that make generic political messages less effective. In this article, we present a small-...
Article
A widely believed claim is that citizens tend to selectively expose themselves to like-minded information. However, when individuals find the information useful, they are more likely to consume cross- cutting sources. While crises such as terror attacks and pandemics can enhance the utility of cross-cutting information, empirical evidence on the ro...

How is political news shared online? This fundamental question for political communication research in today’s news ecology is still poorly understood. In particular, very little is known about whether and how news sharing differs from news viewing. Based on a unique dataset of ≈ 870,000 URLs shared ≈ 100 million times on Facebook, grouped by count...

Social media platforms take on increasingly big roles in political advertising. Microtargeting techniques facilitate the display of tailored advertisements to specific subsegments of society. Scholars worry that such techniques might cause political information to be displayed to only very small subgroups of citizens. Or that targeted communication...

The COVID-19 pandemic has created one of the largest medical, financial, and social disruption in history. In the fight against this virus, many European governments have turned to collecting and using online data (for various technological applications) as a key strategic remedy. This study consists of data from a national representative survey in...

During times of crisis or instability, citizens are more reliant on news media as a source of information. We need to better understand which news media people consume, how it changes over time, and whether two important predictors of news use – political interest and news media trust – affect news use during times of crisis. Specifically, we inves...

The digital traces that people leave through their use of various online platforms provide tremendous opportunities for studying human behavior. However, the collection of these data is hampered by legal, ethical and technical challenges. We present a framework and tool for collecting these data through a data donation platform where consenting par...
Article
Economic coverage often takes the perspective of the audience rather than financial insiders by applying news values such as domestication and identification, especially in democratic-corporatist countries and since the Great Recession. While research has looked into how this mainstreaming of economic news materializes in news content (role perform...

A growing number of communication scholars have pushed for increased accountability and transparency in scholarship. While perspectives on open scholarship practices (OSPs) are noted in editorials and positions papers, we lack insights into how the larger community understands, feels about, engages with, and supports OSPs in practice. A mixed-metho...

The transition from low- to high-choice media environments has had far-reaching implications for citizens’ media use and its relationship with political knowledge. However, there is still a lack of comparative research on how citizens combine the usage of different media and how that is related to political knowledge. To fill this void, we use a un...

This commentary reflects on the notion of ‘dark participation’ which is central in this thematic issue. It asks whether there are patches of light and whether our research is becoming too obsessed with the darkness?

In the last 10 years, many canonical findings in the social sciences appear unreliable. This so-called “replication crisis” has spurred calls for open science practices, which aim to increase the reproducibility, replicability, and generalizability of findings. Communication research is subject to many of the same challenges that have caused low re...

News diversity in the media has for a long time been a foundational and uncontested basis for ensuring that the communicative needs of individuals and society at large are met. Today, people increasingly rely on online content and recommender systems to consume information challenging the traditional concept of news diversity. In addition, the very...

Political advertisers have access to increasingly sophisticated microtargeting techniques. One such technique is tailoring ads to the personality traits of citizens. Questions have been raised about the effectiveness of this political microtargeting (PMT) technique. In two experiments, we investigate the causal effects of personality-congruent poli...

Deepfakes are perceived as a powerful form of disinformation. Although many studies have focused on detecting deepfakes, few have measured their effects on political attitudes, and none have studied microtargeting techniques as an amplifier. We argue that microtargeting techniques can amplify the effects of deepfakes, by enabling malicious politica...

The complexity and diversity of today’s media landscape provides many challenges for scholars studying online news consumption. Yet it is unclear how news consumers navigate online. Moving forward, we used a custom-built browser plug-in—passively tracking Dutch online news consumers 24/7—to examine how context (website) and content (news topic) fea...

Article
As people increasingly rely on online media and recommender systems to consume information, engage in debates and form their political opinions, the design goals of online media and news recommenders have wide implications for the political and social processes that take place online and offline. Current recommender systems have been observed to pr...

The mediating role of emotional reactions and their relevance for political attitudes and behavioral intentions has remained an understudied subject, and the extant literature has mostly overlooked the importance of political campaigning on social media in the context of the European Union (EU). Using an experimental design, we test whether politic...
Article
The news media’s ability to mobilise citizens to participate politically by emphasising elite conflict in politics is not well understood. This article argues that citizens may gain knowledge when exposed to conflict news framing. It further theorises that whether they translate their knowledge into political participation is conditioned by their o...

Voting Advice Applications (VAAs) provide voting recommendations to millions of people. As these voting recommendations are based on users’ answers to attitude questions, the framing of these questions can have far-reaching consequences. The current study reports on a field experiment in which the framing of the header above VAA statements (N = 17)...

Tailored political messages are increasingly prevalent in election time, but we know little about how people perceive such data-driven and potentially privacy-infringing techniques. This article examines how demographics relate to privacy concerns and attitudes toward “political behavioral targeting” (PBT), how privacy concerns and attitudes toward...
Article
This study extends the boundary conditions of the work on media effects on polarization by (1) examining whether exposure to news coverage about a contentious political issue polarizes attitudes, especially among the already-polarized citizens; (2) analyzing "easy" and "hard" dimensions of EU attitudes; and (3) offering causal and generalizable evi...

Although previous research has argued that the media play a crucial role in populism’s success, we know too little about how populist messages affect preferences for populist parties. To advance this knowledge, we conducted an experiment in which the core of populist rhetoric – constructing the people as innocent in-group opposed to the establishme...

Framing is a process that involves various actors (e.g., political elites, media, and citizens). The framing effect process is conditioned by influences at the contextual and individual level as well as by the frames themselves. This entry provides a synthesis of extant framing research and develops a model of framing effects as a multilevel effect...

We examine three under-studied factors in selective exposure research. Linking issue publics and motivated reasoning literatures, we argue that selectivity patterns depend on (a) whether an individual is an issue public member; (b) the availability of balanced, pro-, and counter-attitudinal content; and (c) the evidence for a message claim (numeric...
Chapter
Referendum is a term denoting a range of different types of popular votes. Political communication can be of greater importance during referendum campaigns than in general election contexts, given the nature of the decision and a number of factors causing uncertainty for political elites, media, and citizens.

Twitter, blogs and alternative news sites play an increasingly important role in the realm of news and journalism. Journalists often use Twitter to survey the public opinion and to gather information for their articles. At the same time, there has been an explosive growth of non-journalistic websites that have started to compete with professional n...

... A promising methodology that allows researchers to obtain insights into adolescents' social media content are social media data donation packages (Araujo et al., 2022;van Driel et al., 2022). Data donation packages (DDPs) are the personal archives of social media users that contain all their social media data stored by the platform in question. ...
... Nevertheless, this approach clearly tells us that -regardless of the channel through which the information was received -traditional media played a crucial role in the information diet of Germans, Pakistanis, and Indonesians at the time of the data collection. As such, we found a cross-national stable importance of traditional news media in times of crisis, which extends the existing knowledge of similar findings in the Western context (e.g., Vermeer et al., 2022) based on insights from two Global South countries. ...
... Yet, we have comparatively little evidence of this. Recently, Trilling et al. (2022) examined news sharing behaviour in four multi-party systems covering significant variation across countries in Europe. They found that, despite their different media systems and political systems, the underlying processes and sharing patterns in the four countries are remarkably similar. ...
... Based on the data obtained, "Privacy and data protection" showed a strong correlation with "Safe internet use". The developed instrument can therefore also be considered a useful and relevant research tool for the study of risk practices associated with the dimensions obtained in the CFA, such as personal data protection [49,50], communication risks with people and entities [51], and behavioral risks [5]. These three categories are among some that the OECD has classified as potential risks on the Internet, which are also very much in line with elements of Livingstone's and Stoilova's [52] "4Cs" risk proposal. ...
... The Facebook Ad Library is an open to the public-tool created by Facebook in their attempt to make their platform and the advertisements published on it more transparent [Fa22c]. According to Leerssen et al. [LDHV21], the Facebook Ad library documents a selection of ads that appear on Facebook, and although it has been criticized for data not being granular enough, it does constitute a step towards advertising transparency. For this paper, a total of one hundred ads -ten ads per every of the ten companies -were collected using the Facebook Ads library for the month of February 2022 in Germany, creating a selection of companies that were running several advertisements. ...
... Due to the inherent risks of relying on the goodwill of commercial companies for access to societally relevant data, there have been calls and proposals for different models of access to such data (Breuer et al., 2020). One approach that has gained traction recently is collaborating with platform users (Halavais, 2019) through a model typically labeled as "data donation" (Araujo et al., 2021;Boeschoten et al., 2020). When sharing their data with researchers, platform users can and should be given the opportunity to explore and understand their own data. ...
... Extant research seems to present a clear picture of a positive relationship between offline and online news consumption and political knowledge (e.g., Kenski & Stroud, 2006;Ohme, 2020;Van Erkel & Van Aelst, 2021;Wei & Lo, 2008). However, these results are being challenged by recent empirical findings indicating that higher news use does not always lead to greater knowledge about current political events (e.g., Castro et al., 2021;Dimitrova et al., 2011;Moeller & de Vreese, 2019;Strömbäck et al., 2018). While research on direct democratic referendum campaigns has intensified in recent years, most of these studies have focused on citizens' opinion formation processes (for an overview, see Kriesi, 2011), whereas research on media use and knowledge about, and participation in, referendums remains very scarce. ...
... Blue Feed Red Feed, 1 GroundNews 2 ), while in direct communication many other organisations have expressed their intention to incorporate diversity considerations in their future products. Although these attempts are still in their infancy, diversity is becoming increasingly prominent in news recommender design (Bernstein et al., 2021) and recent research indicates that more diverse NRSs do not necessarily impede user utility (Heitz et al., 2022). ...
... Even though the intentional spread of mediated falsehoods has been evident in political discourse for decades, scholars have declared this the 'age of disinformation' (Carmi et al., 2020). Digital information environments have facilitated its extensive, unrestrained and sometimes systematic distribution (Bradshaw et al., 2020), which is often emanating from populist groups (Hameleers and de Vreese, 2021) and, more recently, has become an elementary component of hybrid warfare (Arcos et al., 2022). Simultaneously, concerns about the trustworthiness of media are rising, while political and mediated discourses about disinformation make it seem like trustworthy information is difficult to find (Allcott and Gentzkow, 2017). ...
... To continue to fulfil their role, media actors need the technological skills and tools necessary to evaluate how the technologies they use relate to editorial values. As the discussion on metrics has demonstrated, this requires a better understanding of whether, and if so how, specific technologies affect editorial values (Bernstein et al., 2020;CoE, 2019;Vrijenhoek et al., 2020). Diakopoulous, for example, argues media organisations can verify whether an algorithm lines up with their editorial mission by formulating and then testing a hypothesis on the way in which an algorithm impacts an editorial value (Diakopoulos, 2019). ...
