Social Media


citizen-politician interaction

This project examines the causes and effects of interaction between politicians and members of the public on social media platforms. The overarching question is whether and how social networking sites such as Twitter and Facebook might serve democracy by bringing politicians and citizens into direct, constructive dialog with one another. 

The first stage of the project employed an original dataset of tweets originating from, as well as those directed to, Members of Parliament and Congress in the Netherlands, United Kingdom, and United States, and explored the interactions between these different actors in several ways.

  • "Thanks for (Actually) Responding! How Citizen Demand Shapes Politicians’ Interactive Practices on Twitter" was just published (online before print) in New Media & Society. This article examines the factors that impact whether and to what extent politicians choose to engage with members of the public in genuinely reciprocal dialogue. I find that, contrary to previous expectations, structural factors such as the electoral system and culture of politicians' digital media use are not correlated with legislators' level of reciprocal engagement. Instead, the data suggest that the amount and the tone of demands received from the public condition politicians' willingness to converse via Twitter.
  • "The Great Leveler? Comparing Citizen-Politician Twitter Engagement across Three Western Democracies," which was recently published (online before print) in European Political Science, asks whether politicians are using social media to engage average citizens - and not just other political and media elite - in dialog. I find that a large share of politicians' genuinely reciprocal exchanges do in fact include average citizens. Though there is much room for improvement, this study suggests that Twitter is indeed opening spaces for citizens and policymakers to engage one another on matters of political import.

  • “She Belongs in the Kitchen, Not in Congress? Political Engagement and Sexism on Twitter,” co-authored with Karin Koole (Leiden University), is forthcoming in Javnost - The Public. The article recognizes that social media provide mechanisms and spaces for members of the public to share their opinions as never before. They offer direct lines of communcation to democratic representatives and, on a societal scale, provide policymakers, journalists, and other elite gatekeepers with a better sense of the will of (at least some portion of) the people. But, the paper asks, are the views expressed on social media worth listening to? After all, instantaneous, impersonal, and anonymous communication has the tendency to bring out the worst in us - inviting crassness, negativity, and abuse of others, including racism and sexism. Indeed, extensive evidence suggests that women face particularly high levels of abuse online. And yet we know relatively little about the role of sexism in citizen's digitally-mediated interactions with their political representatives. Do people engage more with male politicians? Do they direct more criticism and hostility toward women? While the Twitter data employed in this study do provide some evidence that members of the public engage with men slightly more than with women, citizens actually direct more positive messages toward their female representatives. The codebook for this article will shortly be available on my Supplementary Materials page.

In the next stage of this project, which I have just begun to develop with Leiden University colleague Michael Meffert, we are using experimental research designs to explore (1) whether the mechanisms my own and previous studies have suggested might promote interactivity between politicians and citizens bear out and (2) whether interaction between politicians and citizens has positive effects on citizens' political perceptions and sense of efficacy. We ran our first survey experiment in summer 2017 in the United States and are currently analyzing the data while also working on several experiments we plan to run in the US and various Western European countries.


Comparative online campaign communication

In the lead up to the most recent US presidential elections, Jennifer Stromer-Galley and her team at Syracuse University began the Illuminating 2016 project, which seeks "to understand political discourses engaged by the ... presidential candidates on social media." The project resulted in "a platform for collecting, analyzing and visualizing data, using advanced computational approaches" (see the project overview here). In particular, the team developed machine learning classification models that automatically code candidates' Facebook and Twitter posts to distinguish between common forms of political messaging (e.g., mobilizing, ceremonial, persuasive, informative, attack). Using these tools, Stromer-Galley and her team are analyzing the impact of polling on candidates' social media communication, civility in online discourse, and numerous other digital communication dynamics.

Beginning in January 2017, I was a visiting scholar in Stromer-Galley's Center for Computational and Data Science, and during my time at Syracuse, I took the lead in expanding this project to other countries. We have now collected Facebook and Twitter data from the 2015 Finnish and 2017 Dutch, French, UK, and German elections. We are currently working on developing machine learning algorithms to classify the data in each country and plan to publish a number of comparative studies on this basis.



I am also working with scholars at Syracuse on projects examining the role of bots on social media during European elections and on exploring automated techniques for detecting "fake news" online.

Media Framing


frame duration

In "The Life and Death of Frames: Dynamics of Media Frame Duration," recently published in the International Journal of Communication, Michael Meffert (Leiden University) and I note that though media framing scholars have long examined why journalists select certain frames over others at a given point in time, we know much less about why certain frames persist over time in the media while others fade away and still others disappear very quickly. In this study, we bring attention to the analysis of frame duration and offer an approach based in event-history methodologies that can assess the causes of repeated frame deployment over both long and short periods of time.

The study of frame duration holds a particular advantage over empirical analyses of frame selection in that it avoids problems with systematic selection bias inherent in the latter. Unable to determine "what might have been," most empirical studies of frame selection cannot fully ascertain what frames journalists could have selected at a given point but ultimately did not. As such, the data resulting from these studies systematically omit frames that were not selected - truncating the dependent variable. By comparing only those frames that are already selected to one another, examination of frame duration avoids this problem. 

By way of illustration, we examine British coverage of the 2006 Danish Muhammad cartoon controversy, demonstrating a rigorous and analytically sound approach to the longitudinal analysis of media frame dynamics.
