The Role of Source Credibility and Message Credibility in Fake News Engagement. Perspectives from an Experimental Study

Summary/Abstract: Nowadays controversial stories, conspiracy theories, or false information are massively shared on social media. Fake news is supported by the online environment because it generates traffic and financial benefits (Tandoc et al., 2018). It is a chain — users share the news on their feed, then they receive the same type of content, later on, creating the illusion of veracity through popularity. Media credibility becomes more and more relevant in the context of the proliferation of fake news. The present paper addresses the mediating role of source and message credibility in relationship with the engagement with ‘poor journalistic’ content. We aimed to identify the effects of media reputation and of the facticity of the news on (digital) behavior such as the intent to disseminate or to comment on fake news on social media and also on discussing these contents with friends. For this purpose, we applied a 2x2 between subjects online experiment by manipulating the (1) the source (high vs. low reputation online media outlets) and (2) information facticity (high vs. low). Participants (N=177), aged 18 to 53 years were selected via Facebook and the study was carried out in February 2020. The results of our research are in line with previous literature that underlined the role of source and message credibility in influencing online and offline news engagement. We observed that source credibility has an impact on news sharing on Facebook and that message credibility encourages discussion with friends. This applies to both veridical and false information. The most important takeaway of our study is perhaps that users are aware that high reputation media outlets can make mistakes. Besides,media reputation is subject to change and is related to the audiences.
