Research Lab

I work collaboratively with a group of fantastic undergraduate research assistants as part of the Social Networks and Political Psychology Lab (SNaPP Lab).

Research Interests

I am broadly interested in how contentious interpersonal interactions about politics affect the way that individuals perceive conflict in their environment, evaluate other people, and engage within the political system. The two major projects of my research agenda are discussed below.

I have received funding from the NSF for a project titled “Understanding the Mechanisms for Disengagement from Contentious Political Interaction (NSF-1423788).” I am currently working on a series of experimental studies that identify the mechanisms driving social disengagement from politics, which people are most susceptible to social stress in the political sphere, and which situations generate the most pressure toward political disengagement. We are working to implement psychophysiological measurement techniques to better assess emotional reactions to contentious political experiences. In future work, we also hope to incorporate genetic and hormonal data collection into our work.

I am also working on a book project, titled “Newspaper to News Feed: How Social Media Has Changed the Way We Access News and Discuss Politics.” Engaging with political content on the Facebook News Feed incorporates novel behaviors at the intersection of political expression, political information seeking, and political discussion. My key argument is that the defining characteristics of engagement with this content are uniquely suited to foster and perpetuate affective polarization, defined as partisans’ increasingly negative feelings and negative trait attribution toward identifiers of the opposing party. In the first half of the book, I use original survey data to demonstrate that the kinds of users who generate political content on Facebook, and their reasons for doing so, create a communication ecosystem that disproportionately circulates polarizing information. People can and do make inferences about the political views of their social connections, based on both the political, and apolitical, content their Facebook friends post. In the second half of the book, I theorize how engagement with this content contributes to affective polarization, testing a series of hypotheses in experiments drawing on techniques from political communication and political psychology. I show that Facebook users judge other users with whom they disagree to be less politically knowledgeable and to use less reliable news sources, and they evaluate out-partisans as being ignorant and dogmatic. Paired with cognitive biases resulting from exposure to aggregated information about the number of users who endorse political content, people overestimate both the proportion of the population that shares their opinions and the differences between the political parties..
