According to selective exposure theory, people tend to select news media that are perceived to provide attitude-consonant information and avoid those that are perceived to provide dissonant information. Despite this, research on selective exposure seldom takes people’s perceptions of media bias into account, while research on perceptions of media bias seldom links such perceptions to subsequent media use. To address this, the purpose of this study is to investigate perceptions of mainstream media bias and whether such perceptions mediate the effect of using political alternative media on subsequent mainstream media use. Empirically, the study utilizes a three-wave panel survey during the 2022 Swedish parliamentary election campaign to investigate perceptions of public service media bias and subsequent use of public service media. Among other things, the results show that the use of right-wing political alternative media influences perceptions of leftist public service bias, which in turn mediates the effect of using right-wing alternative media on subsequent public service media use.

解决选择性曝光研究中的盲点：对媒体偏见的看法及其对主流媒体使用的影响。中介分析

根据选择性暴露理论，人们倾向于选择被认为提供态度一致信息的新闻媒体，而避免那些被认为提供不和谐信息的新闻媒体。尽管如此，关于选择性曝光的研究很少考虑到人们对媒体偏见的看法，而对媒体偏见的看法的研究很少将这种看法与随后的媒体使用联系起来。为了解决这个问题，本研究的目的是调查对主流媒体偏见的看法，以及这种看法是否中介了使用政治替代媒体对后续主流媒体使用的影响。从实证上讲，该研究利用 2022 年瑞典议会竞选期间的三波小组调查来调查对公共服务媒体偏见的看法以及随后对公共服务媒体的使用。除其他外，结果表明，右翼政治替代媒体的使用会影响对左翼公共服务偏见的看法，这反过来又中介了使用右翼替代媒体对后续公共服务媒体使用的影响。
