How Much Data Should I Request? Balancing Richness and Compliance in Digital Trace Data Donations
Digital trace “data donation” studies offer researchers a unique opportunity to collect high-quality behavioral data, but decisions about the scope of requested data can impact both dataset richness and participant compliance. This paper examines the tradeoffs between requesting larger data packages, which include more extensive historical records, and participants’ willingness to donate. In a randomized experiment with Facebook and Instagram dat…
Is a single model enough? The systematic comparison of computational approaches for detecting populist radical right content
The rise of populist radical right (PRR) ideas stresses the importance of understanding how individuals engage with PRR content online. However, this task is complicated by the variety of channels through which such engagement can take place. In this article, we systematically compare computational approaches for detecting PRR content in textual data. Using 66 dictionary, classic supervised machine learning, and deep learning (DL) models, we comp…
Tracing Knowledge Gaps
The knowledge gap hypothesis—the assumption that an increasing flow of news on a topic fosters a gap in knowledge between the more and the less educated—has been demonstrated in numerous studies throughout the past 60 years. Knowledge gaps are attributed to individual differences in media selection and information processing capacities. However, it has been difficult to investigate the relative influence of selection and processing with conventio…

Misperceptions of Public Opinion During Crises
Where did you come from, where did you go? News trajectories in Germany and Switzerland
The article examines news trajectories used by individuals to access mainstream journalistic media in Germany and German-speaking Switzerland during the first peak of COVID-19 in Europe. It discusses the role of individual characteristics related to sociodemographics, political, and media attitudes in predisposition towards specific modes of news access. For this aim, it combines survey data with data on individuals’ engagement with news automati…

The inconsistency of immigration policy
To what extent can we infer government objectives from policies on paper? We show that this assumption in migration scholarship is problematic because most states adopt immigration policies that are inconsistent, combining or alternating between contradictory objectives. Further, we develop a measure to track how immigration policy inconsistency varies over time. We use these methods to demonstrate that some of the main theories of policy inconsi…
Populist Radical-Right Attitudes, Political Involvement and Selective Information Consumption
This study seeks to understand how populist radicalright (PRR) attitudes and political involvement relate to individuals' political information consumption and selective exposure to ideological content. The study approaches political information selection as a twostep phenomenon: first, individuals use different amounts of political information, and second, they rely on attitude-consonant information to different degrees. Results from a combinati…
Improving the Quality of Individual-Level Web Tracking
This article evaluates the quality of data collection in individual-level desktop web tracking used in the social sciences and shows that the existing approaches face sampling issues, validity issues due to the lack of content-level data and their disregard for the variety of devices and long-tail consumption patterns as well as transparency and privacy issues. To overcome some of these problems, the article introduces a new academic web tracking…
Hyperpartisan, Alternative, and Conspiracy Media Users
While there is growing academic attention to readers of hyperpartisan, alternative, and conspiracy (HAC) media, our understanding of these sites has developed in separate bodies of work. We make a case for studying HAC media in unison, recognizing them as different information sources that share the same underlying anti-establishment sentiment. We do so by painting a detailed portrait of HAC media users, detailing 1) who consumes HAC media; 2) ho…
Conservatism Negatively Predicts Creativity
Previous studies have found a negative relationship between creativity and conservatism. However, as these studies were mostly conducted on samples of homogeneous nationality, the generalizability of the effect across different cultures is unknown. We addressed this gap by conducting a study in 28 countries. Based on the notion that attitudes can be shaped by both environmental and ecological factors, we hypothesized that parasite stress can also…
The News Sharing Gap
Are journalists and Facebook users equally interested in political news? Introducing the conceptualization and measurement of the “news sharing gap”, this study compares the sharing of political news by Facebook users to the production of political news by news media organizations. To paint a broad picture of these differences, we compare the news sharing gap (a) across election and routine periods and (b) across eight countries: Australia, Austr…
Electoral news sharing
Patterns of news consumption are changing drastically. Citizens increasingly rely on social media such as Facebook to read and share political news. With the power of these platforms to expose citizens to political information, the implications for democracy are profound, making understanding what is shared during elections a priority on the research agenda. Nevertheless, to the best of our knowledge, no study has yet explicitly explored how elec…
Do (Not!) Track Me
This paper offers a critical look at the promises and drawbacks of a popular, novel data collection technique—online tracking—from the point of view of sample composition. Using data from two large-scale studies about political attitudes and information consumption behavior carried out in Germany and Switzerland, we find that the likelihood of participation in a tracking study at several critical dropout points is systematically related to the ge…
News, Threats, and Trust
This study explores shifts in political trust during the outbreak of the COVID-19 pandemic in Switzerland, examining the role that media consumption and threat perceptions played in individuals’ trust in politics. We combine panel surveys taken before and during the first nation-wide lockdown with webtracking data of participants' online behaviour to paint a nuanced picture of media effects during the crisis. Our work has several findings. First,…
Affective Interpersonal Touch in Close Relationships
Interpersonal touch behavior differs across cultures, yet no study to date has systematically tested for cultural variation in affective touch, nor examined the factors that might account for this variability. Here, over 14,000 individuals from 45 countries were asked whether they embraced, stroked, kissed, or hugged their partner, friends, and youngest child during the week preceding the study. We then examined a range of hypothesized individual…
A Sadness Bias in Political News Sharing? The Role of Discrete Emotions in the Engagement and Dissemination of Political News on Facebook
In this study, we address the role of emotions in political news sharing on Facebook to better understand the complex relationship between journalism, emotions, and politics. Categorizing Facebook Reactions (particularly, the Sad, Angry, Love, and Wow Reactions) according to the discrete emotions model, we evaluate how positive versus negative political content relates to emotional responses, and how this consequentially influences the degree to …
Sex Differences in Mate Preferences Across 45 Countries
Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives—an evolutionary psychological perspective and a biosocial role perspective—offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, and the li…
Universality of the Triangular Theory of Love
The Triangular Theory of Love (measured with Sternberg's Triangular Love Scale - STLS) is a prominent theoretical concept in empirical research on love. To expand the culturally homogeneous body of previous psychometric research regarding the STLS, we conducted a large-scale cross-cultural study with the use of this scale. In total, we examined more than 11,000 respondents, but as a result of applied exclusion criteria, the final analyses were ba…
