Survey Professionalism: New Evidence from Web Browsing Data
Online panels have become an important resource for research in political science, but the compensation offered to panelists incentivizes them to become “survey professionals,” raising concerns about data quality. We provide evidence on survey professionalism exploring three US samples of subjects who donated their browsing data, recruited via Lucid, YouGov, and Facebook (total $n = 3,886$ ). Survey professionalism is common, but varies across sa…
Effects of Over-Time Exposure to Partisan Media and Coverage of Polarization on Perceived Polarization
Does School Debating Reduce Vulnerability to Misinformation? A Field Experiment in Poland
The idea that debating enhances political knowledge and critical thinking has been entertained by scholars of democracy for a long time. Given recent concern about a crisis of misinformation, we explore the idea that debating makes people less vulnerable to misinformation and conspiracy thinking. In a field experiment, we recruited high school students in 18 schools in Poland (n=430) and assigned them to either a debate workshop or a control cond…

Large language models as a substitute for human experts in annotating political text
Large-scale text analysis has grown rapidly as a method in political science and beyond. To date, text-as-data methods rely on large volumes of human-annotated training examples, which place a premium on researcher resources. However, advances in large language models (LLMs) may make automated annotation increasingly viable. This paper tests the performance of GPT-4 across a range of scenarios relevant for analysis of political text. We compare G…
Analysis of Web Browsing Data: A Guide
The use of individual-level browsing data, that is, the records of a person’s visits to online content through a desktop or mobile browser, is of increasing importance for social scientists. Browsing data have characteristics that raise many questions for statistical analysis, yet to date, little hands-on guidance on how to handle them exists. Reviewing extant research, and exploring data sets collected by our four research teams spanning seven c…
Non-News Websites Expose People to More Political Content Than News Websites: Evidence from Browsing Data in Three Countries
Most scholars focus on the prevalence and democratic effects of (partisan) news exposure. This focus misses large parts of online activities of a majority of politically disinterested citizens. Although political content also appears outside of news outlets and may profoundly shape public opinion, its prevalence and effects are under-studied at scale. This project combines three-wave panel survey data from three countries (total N = 7,266) with o…
Truth and Bias, Left and Right: Testing Ideological Asymmetries with a Realistic News Supply
The debate around “fake news” has raised the question of whether liberals and conservatives differ, first, in their ability to discern true from false information, and second, in their tendency to give more credit to information that is ideologically congruent. Typical designs to measure these asymmetries select, often arbitrarily, a small set of news items as experimental stimuli without clear reference to a “population of information.” This pre…
Null effects of news exposure: A test of the (un)desirable effects of a ‘news vacation’ and ‘news binging’
Democratic theorists and the public emphasize the centrality of news media to a well-functioning society. Yet, there are reasons to believe that news exposure can have a range of largely overlooked detrimental effects. This preregistered project examines news exposure effects on desirable outcomes, i.e., political knowledge, participation, and support for compromise, and detrimental outcomes, i.e., attitude and affective polarization, negative sy…
When Do Sources Persuade? The Effect of Source Credibility on Opinion Change
Discussions around declining trust in the US media can be vague about its effects. One classic answer comes from the persuasion literature, in which source credibility plays a key role. However, existing research almost universally takes credibility as a given. To overcome the potentially severe confounding that can result from this, we create a hypothetical news outlet and manipulate to what extent it is portrayed as credible. We then randomly a…
The (null) over-time effects of exposure to local news websites: Evidence from trace data
Scholars and observers attribute many democratic benefits to local news media. This paper examines exposure to local and national news media websites, side-by-side in one model, testing their over-time effects on political participation, knowledge, and affective and attitude polarization. We test whether traditionally disengaged or disadvantaged groups (i.e., racial minorities, those with low education levels, politically disinterested, and those…

Horseshoe Patterns: Visualizing Partisan Media Trust in Germany
A trusted media is crucial for a politically informed citizenry, yet media trust has become fragile in many Western countries. An underexplored aspect is the link between media (dis)trust and populism. The authors visualize media trust across news outlets and partisanship in Germany, for both mainstream and 'alternative' news sources. For each source, average trust is grouped by partisanship and sorted from left to right, allowing within-source c…
