The consequences of online partisan media

What role do ideologically extreme media play in the polarization of society? Here we report results from a randomized longitudinal field experiment embedded in a nationally representative online panel survey (N = 1,037) in which participants were incentivized to change their browser default settings and social media following patterns, boosting the likelihood of encountering news with either a left-leaning (HuffPost) or right-leaning (Fox News) slant during the 2018 US midterm election campaign. Data on ≈ 19 million web visits by respondents indicate that resulting changes in news consumption persisted for at least 8 wk. Greater exposure to partisan news can cause immediate but short-lived increases in website visits and knowledge of recent events. After adjusting for multiple comparisons, however, we find little evidence of a direct impact on opinions or affect. Still, results from later survey waves suggest that both treatments produce a lasting and meaningful decrease in trust in the mainstream media up to 1 y later. Consistent with the minimal-effects tradition, direct consequences of online partisan media are limited, although our findings raise questions about the possibility of subtle, cumulative dynamics. The combination of experimentation and computational social science techniques illustrates a powerful approach for studying the long-term consequences of exposure to partisan news.

An Evening on Mars

Chapter 35 begins with the Red Planet success of Pathfinder and the Mars rover Sojourner, and continues with Bradbury’s hosting of NASA’s 1998 Thomas O. Paine Memorial Award ceremony under the title “Witness & Celebrate: An Evening on Mars with Ray Bradbury.” Distinguished film actors, including Nichelle Nichols, John Rhys-Davies, and Charlton Heston, read from ten Bradbury works. The chapter also discusses “The Affluence of Despair,” Bradbury’s Jeremiad against America’s obsession with self-performance and extreme media reporting, which he likened to the world he had tried to prevent in Fahrenheit 451. The chapter closes with an analysis of Bradbury’s love for F. Scott Fitzgerald’s Tender is the Night, and what this love reveals about his ability to fend off the worst effects of fame.

The relevance of public policies for the sustainability of community media: Lessons from Argentina

Since 2004 and for the first time in the history of broadcasting in the region, a dozen Latin American countries have acknowledged community radio and television stations as legal providers of audiovisual communication services. In Argentina, a law passed in 2009 not only awarded legal recognition to the sector, it also provided a promotion mechanism for community media. In this respect, it was one of the most ambitious ones in the region. The driving question is: How relevant are public policies for the sustainability of community media in Argentina? The argument is: even though the sector of community media has developed and persisted for decades in illegal conditions imposed by the state, the legalization and promotion policies carried out by the state from the perspective of human rights in a context of extreme media ownership concentration have been critical to the growth and sustainability of non-profit media.

The Educative Effects of Extreme Television Media

This article investigates whether exposure to extreme television media informs citizens about politics. Using lab experiments with both student and non-student samples, I find that extreme media produce higher levels of political knowledge and that they also produce higher levels of negative affect among viewers compared with control groups. I also show that extreme media are at least as informative as traditional news. This research adds to the growing literature on media effects in a polarized media environment, showing that extreme television media can have a beneficial impact on at least one important area of U.S. politics: citizen competence. To account for external validity and popular conceptions on extreme media’s non-informative nature, I use cross-sectional data from the 2008 National Annenberg Election Survey finding that extreme television viewership correlates with greater political knowledge, while controlling for other known predictors.
