Environmental Communication on Twitter: The Impact of Source, Bandwagon Support, and Message Valence on Target Audiences

Abstract

The goal of the research is to empirically examine how different factors affect the dissemination of environmental protection messages on social media. The theoretical foundation of the research is based on the literature on heuristics. Perceived bandwagon support, valence of message framing, and source of information (i.e., source credibility) were examined as the independent variables. The dependent variables were perceived information credibility, intention to share the message, and intention to read the article attached to the message. Four online experiments were conducted, and college students were sampled. Overall, the findings suggest that the impact of source, bandwagon support, and message valence affect behavioral intentions and perceived information credibility in various ways, and the extent of such impacts is context-dependent. The findings of the study would advance our theoretical understanding of how we use psychological heuristics to process information related to environmental communication. The findings would also help environmental organizations and activists to better communicate with their potential audiences.
