Abstract

Focusing on a polarized issue—U.S. gun violence—this study examines agenda setting as an antecedent of political expression on social media. A state-of-the-art machine-learning model was used to analyze news coverage from 25 media outlets—mainstream and partisan. Those results were paired with a two-wave panel survey conducted during the 2018 U.S. midterm elections. Findings show mainstream media shape public opinion about gun violence, which then stimulates expression about the issue on social media. The study also reveals that partisan media’s gun violence coverage has significant cross-cutting effects. Notably, exposure to conservative media will decrease public salience of gun violence, pivot opinion in a more conservative direction, and discourage social media expression; and all of these effects are stronger among liberals.

议程设置、交叉效应和社交媒体上的政治表达:枪支暴力案件

关注一个两极分化的问题——美国。枪支暴力——这项研究考察了议程设置作为社交媒体上政治表达的先决条件。一个最先进的机器学习模型被用来分析来自25家主流和党派媒体的新闻报道。这些结果与2018年美国中期选举期间进行的两波小组调查相匹配。调查结果显示，主流媒体塑造了公众对枪支暴力的看法，然后刺激了社交媒体上对这一问题的表达。该研究还显示，党派媒体对枪支暴力的报道具有显著的交叉效应。值得注意的是，接触保守媒体会减少公众对枪支暴力的关注，将舆论转向更保守的方向，并阻碍社交媒体的表达;所有这些影响在自由主义者中更为强烈。

期刊介绍： Empirical research in communication began in the 20th century, and there are more researchers pursuing answers to communication questions today than at any other time. The editorial goal of Communication Research is to offer a special opportunity for reflection and change in the new millennium. To qualify for publication, research should, first, be explicitly tied to some form of communication; second, be theoretically driven with results that inform theory; third, use the most rigorous empirical methods; and fourth, be directly linked to the most important problems and issues facing humankind. Critieria do not privilege any particular context; indeed, we believe that the key problems facing humankind occur in close relationships, groups, organiations, and cultures.
