Following the 2016 U.S. presidential election, many have expressed concern about the effects of false stories (“fake news”), circulated largely through social media. We discuss the economics of fake news and present new data on its consumption prior to the election. Drawing on web browsing data, archives of fact-checking websites, and results from a new online survey, we find: (i) social media was an important but not dominant source of election news, with 14 percent of Americans calling social media their “most important” source; (ii) of the known false news stories that appeared in the three months before the election, those favoring Trump were shared a total of 30 million times on Facebook, while those favoring Clinton were shared 8 million times; (iii) the average American adult saw on the order of one or perhaps several fake news stories in the months around the election, with just over half of those who recalled seeing them believing them; and (iv) people are much more likely to believe stories that favor their preferred candidate, especially if they have ideologically segregated social media networks.

Exposure to news, opinion and civic information increasingly occurs through social media. How do these online networks influence exposure to perspectives that cut across ideological lines? Using de-identified data, we examined how 10.1 million U.S. Facebook users interact with socially shared news. We directly measured ideological homophily in friend networks, and examine the extent to which heterogeneous friends could potentially expose individuals to cross-cutting content. We then quantified the extent to which individuals encounter comparatively more or less diverse content while interacting via Facebook’s algorithmically ranked News Feed, and further studied users’ choices to click through to ideologically discordant content. Compared to algorithmic ranking, individuals’ choices about what to consume had a stronger effect limiting exposure to cross-cutting content.

The wide availability of user-provided content in online social media facilitates the aggregation of people around common interests, worldviews, and narratives. However, the World Wide Web (WWW) also allows for the rapid dissemination of unsubstantiated rumors and conspiracy theories that often elicit rapid, large, but naive social responses such as the recent case of Jade Helm 15––where a simple military exercise turned out to be perceived as the beginning of a new civil war in the United States. In this work, we address the determinants governing misinformation spreading through a thorough quantitative analysis. In particular, we focus on how Facebook users consume information related to two distinct narratives: scientific and conspiracy news. We find that, although consumers of scientific and conspiracy stories present similar consumption patterns with respect to content, cascade dynamics differ. Selective exposure to content is the primary driver of content diffusion and generates the formation of homogeneous clusters, i.e., “echo chambers.” Indeed, homogeneity appears to be the primary driver for the diffusion of contents and each echo chamber has its own cascade dynamics. Finally, we introduce a data-driven percolation model mimicking rumor spreading and we show that homogeneity and polarization are the main determinants for predicting cascades’ size.

The spreading of misinformation online

A review of research suggests that the desire for opinion reinforcement may play a more important role in shaping individuals’ exposure to online political information than an aversion to opinion challenge. The article tests this idea using data collected via a webadministered behavior-tracking study with subjects recruited from the readership of 2 partisan online news sites (N = 727). The results demonstrate that opinion-reinforcing information promotes news story exposure while opinion-challenging information makes exposure only marginally less likely. The influence of both factors is modest, but opinionreinforcing information is a more important predictor. Having decided to view a news story, evidence of an aversion to opinion challenges disappears: There is no evidence that individuals abandon news stories that contain information with which they disagree. Implications and directions for future research are discussed.

Echo chambers online?: Politically motivated selective exposure among Internet news users

New Information and Communication Technologies (ICTs) are changing the ways in which activists communicate, collaborate and demonstrate. Scholars from a wide range of disciplines, among them sociology, political science and communication, are working to understand these changes. The diversity of perspectives represented enriches the literature, providing an abundant repertoire of tools for examining these phenomena, but it is also an obstacle to understanding. Few works are commonly cited across the field, and most are known only within the confines of their discipline. The absence of a common set of organizing theoretical principles can make it difficult to find connections between these disparate works beyond their common subject matter. This paper responds by locating existing scholarship within a common framework for explaining the emergence, development and outcomes of social movement activity. This provides a logical structure that facilitates conversations across the field around common issues of c...

Protest in an Information Society: a review of literature on social movements and new ICTs

This article seeks to reframe the selective exposure debate by demonstrating that people exhibit a preference for opinion-reinforcing political information without systematically avoiding opinion challenges. The results are based on data collected in a national randomdigit-dial telephone survey (n = 1,510) conducted prior to the 2004 U.S. presidential election. Analyses show that Americans use the control afforded by online information sources to increase their exposure to opinions consistent with their own views without sacrificingcontactwithotheropinions.Thisobservationcontradictsthecommonassumption that reinforcement seeking and challenge avoidance are intrinsically linked aspects of the selective exposure phenomenon. This distinction is important because the consequences of challenge avoidance are significantly more harmful to democratic deliberation than those of reinforcement seeking.

Politically Motivated Reinforcement Seeking: Reframing the Selective Exposure Debate

This article takes up Bennett and Iyengar's (2008) call for debate about the future of political communication effects research. We outline 4 key criticisms. First, Bennett and Iyengar are too quick to dismiss the importance of attitude reinforcement, long recognized as an important type of political media influence. Second, the authors take too narrow a view of the sources of political information, remaining fixated on news. Third, they offer an incomplete portrayal of selective exposure, exaggerating the extent to which individuals avoid attitude-discrepant information. Finally, they lean toward determinism when describing the role technologies play in shaping our political environment. In addition, we challenge Bennett and Iyengar's assertion that only brand new theory can serve to help researchers understand today's political communication landscape. We argue that existing tools, notably the Elaboration Likelihood Model (ELM), retain much utility for examining political media effects. Contrary to Bennett and Iyengar's claims, the ELM suggests that the contemporary political information environment does not necessarily lead to minimal effects.

A New Era of Minimal Effects? A Response to Bennett and Iyengar

There has been deepening concern about political polarization in public attitudes toward the scientific community. The “intrinsic thesis” attributes this polarization to psychological deficiencies among conservatives as compared to liberals. The “contextual thesis” makes no such claims about inherent psychological differences between conservatives and liberals, but rather points to interacting institutional and psychological factors as the forces driving polarization. We evaluate the evidence for both theses in the context of developing and testing a theoretical model of audience response to dissonant science communication. Conducting a national online experiment (N = 1,500), we examined audience reactions to both conservative-dissonant and liberal-dissonant science messages and consequences for trust in the scientific community. Our results suggest liberals and conservatives alike react negatively to dissonant science communication, resulting in diminished trust of the scientific community. We discuss ho...
