POLKOM-mandag: Nyheter, ekkokammer og selektiv eksponering
POLKOM inviterer til lunsjmøte mandag 4. september med postdoktor Erik Knudsen ved Universitetet i Bergen og the Digital Social Science Core Facility (DIGSSCORE).
Tittel på foredraget:
«Trusting and reading news from the other side: Experimental evidence on signs of echo chambers, selective exposure, and selective trust in Norway»
For quite some time now, communication scholars have gathered considerable evidence showing that people tend to asymmetrically expose themselves to like-minded over cross-cutting political information, and distrust news sources based on their own political predispositions. Changes in the availability of media choices, paired with increasing fragmentation of the media landscape, has exacerbated people’s tendency to avoid opinion-challenging political information, leading to the creation of echo chambers and further polarization.
While these effects are well documented (especially in the U.S. context), we still lack experimental evidence on how such effects compare against the pull of other competing factors – such as recommendations in social media, negativity bias, and non-political news.
Erik Knudsen will address these limitations and present results from two uniquely designed conjoint experiments that draws on recent advances in causal inference from the social sciences, fielded in a large probability-based panel of Norwegian citizens (The Norwegian Citizen Panel).
First, Knudsen will present a study (N= 4689) that argues for a generic approach to selective exposure research. Empirically, this study dismantles the relative importance of three different forms of selective exposure to like-minded political news that has dominated the communication literature: message cues, party cues, and source cues. This study also investigates whether these effects prevail when three known countervailing forces are accounted for. Second, Knudsen will present a study (N=1955) that disentangles the relative importance of a range of attributes, among them party endorsements, that can affect peoples’ trust in a news source.
Collectively, these studies sheds light on what shapes Norwegian citizens’ news habits and trust in news media.
Tid og sted:
4. september kl.12.00 på rom 418 på Institutt for medier og kommunikasjon, Universitetet i Oslo.
