Investigating the Relationships Among HMP, Credibility, and TPP of News Media and Their Links to News Media Policy Support

Prior research has suggested that perceptions of bias, credibility, and influence of news media may relate to one another but there have been relatively few efforts to integrate these concepts under a coherent theoretical framework. Based on social identity theory, we examined whether political identity relates to hostile media perception (HMP), credibility, and third-person perception (TPP) and if such perceptions in tandem predict attitudes toward news media policies—restriction of news media and media literacy education, which may neutralize the influences of seemingly hostile and untrustworthy news media. Findings from two national online surveys showed that strong partisans tend to perceive stronger HMP and less credibility in news media. Additionally, progressives had greater HMP. HMP and TPP were positively associated with media restriction policy support and media literacy education support. Credibility showed negative associations with restrictive media policy support, whereas the opposite pattern was found in the relationship with media education support. Furthermore, the positive associations between HMP and media policy support were mediated by TPP. The negative associations between credibility and restrictive media policy support were also mediated by TPP.
