“…Microsoft's search engine, Bing, allows users to filter news results by political leaning (Schwartz, 2012). And several researchers are working to build systems that encourage users to adopt more diverse news diets (Munson & Resnick, 2010;Park, Kang, Chung, & Song, 2012). It is plausible that the fictional indicators used here could be commonplace in the next decade.…”

Partisan Paths to Exposure Diversity: Differences in Pro- and Counterattitudinal News Consumption

2014

This study examines selective exposure to political information, arguing that attraction to proattitudinal information and aversion to counterattitudinal information are distinct phenomena, and that the tendency to engage in these behaviors varies by partisanship. Data collected in a strict online experiment support these predictions. Republicans are significantly more likely to engage in selective avoidance of predominantly counterattitudinal information than those with other partisan affiliations, while non-Republicans are significantly more likely to select a story that includes proattitudinal information, regardless of its counterattitudinal content. Individuals across the political spectrum are receptive to predominantly proattitudinal content and to content that offers a mix of views, but the form these preferences take varies by partisanship. The political significance of these findings is discussed.doi: 10.1111/jcom.12105 For much of its history, politically motivated selective exposure has been contested; indeed, many scholars questioned its occurrence (e.g., Chaffee, Saphir, Graf, Sandvig, & Hahn, 2001;Sears & Freedman, 1967). Today, however, the evidence that citizens' news consumption privileges like-minded views over less consonant content is overwhelming (Hart et al., 2009;Stroud, 2011). In an era characterized by unprecedented media choice, uncertainty about the existence of the selective exposure phenomenon has been replaced by questions premised on its existence. Is it on the rise (Garrett, Carnahan, & Lynch, 2013)? What are its consequences (Stroud, 2010)? Under what conditions does it occur (Fischer, Jonas, Frey, & Schulz-Hardt, 2005;Valentino, Banks, Hutchings, & Davis, 2009)? And when and why do partisan differences in selectivity appear (Iyengar, Hahn, Krosnick, & Walker, 2008)?In this paper, we advance our understanding of selective exposure in two ways. First, we offer new evidence in the debate over the need to distinguish between Corresponding author: R. Kelly Garrett; e-mail: garrett.258@osu.edu Partisan Paths to Exposure Diversity selective approach, the tendency to seek information consistent with one's prior beliefs, and selective avoidance, a drive to avoid contradictory information. The conventional understanding of selective exposure as the pairing of selective approach with equally strong selective avoidance has been criticized, both theoretically (e.g., Garrett, 2009b) and empirically (e.g., Gentzkow & Shapiro, 2011), but several prominent scholars recently have embraced the classical view (e.g., Bennett & Iyengar, 2008). This study aims to extend earlier scholarship by offering the most stringent experimental test to date of whether selective approach is the stronger tendency.Building on new evidence for the distinction between selective approach and selective avoidance, our second contribution is to examine partisan differences in these phenomena. Recent research has highlighted not only differences in how partisans approach and think about the world (see, for example, Jost...

“…Very closely related to our work is NewsCube by Park et al (Park, Lee, and Song 2010;Park et al 2012), a system for news aggregation, processing and diversity-aware delivery. DiversiNews and NewsCube have much common -they both choose to offer diversity through a stand-alone news portal, and a lot of the preprocessing work is therefore similar across the two systems.…”

DiversiNews: Surfacing Diversity in Online News

For most events of at least moderate significance, there are likely tens, often hundreds or thousands of online articles reporting on it, each from a slightly different perspective. If we want to understand an event in depth, from multiple perspectives, we need to aggregate multiple sources and understand the relations between them. However, current news aggregators do not offer this kind of functionality. As a step towards a solution, we propose DiversiNews, a real-time news aggregation and exploration platfom whose main feature is a novel set of controls that allow users to contrast reports of a selected event based on topical emphases, sentiment differences and/or publisher geolocation. News events are presented in the form of a ranked list of articles pertaining to the event and an automatically generated summary. Both the ranking and the summary are interactive and respond in real time to user’s change of controls. We validated the concept and the user interface through user tests with positive results.

Understanding news outlets’ audience-targeting patterns

The power of the press to shape the informational landscape of a population is unparalleled, even now in the era of democratic access to all information outlets. However, it is known that news outlets (particularly more traditional ones) tend to discriminate who they want to reach, and who to leave aside. In this work, we attempt to shed some light on the audience targeting patterns of newspapers, using the Chilean media ecosystem. First, we use the gravity model to analyze geography as a factor in explaining audience reachability. This shows that some newspapers are indeed driven by geographical factors (mostly local news outlets) but some others are not (national-distribution outlets). For those which are not, we use a regression model to study the influence of socioeconomic and political characteristics in news outlets adoption. We conclude that indeed larger, national-distribution news outlets target populations based on these factors, rather than on geography or immediacy.
