Hashtag Wars: Political Disinformation and Discursive Struggles on Twitter Conversations During the 2018 Brazilian Presidential Campaign

Abstract

In this article, we analyze the spread of political disinformation in events of discursive struggles on Twitter, during the 2018 presidential election in Brazil. These were disputes for the hegemonic narrative between two stories based on opposed hashtags: one based on news from mainstream media and the other, based on disinformation, mostly from hyperpartisan outlets. Our goal was to understand how hyperpartisan outlets created and shaped these discursive struggles and the strategies used to spread disinformation to create an “alternative narrative” to the facts. Our case study is focused on two discursive struggles, for which we will use critical discourse analysis and social network analysis. Our findings suggest that (1) the structure of the hashtag wars was very polarized and right-wing groups had higher exposure to hyperpartisan content and disinformation, while traditional media discourse circulates more among other different ideological clusters; (2) right-wing hyperpartisan media mostly used biased framing and polarized ideological discourse structure as manipulative strategies to reframe the events and create a counter-narrative (and thus, to create the dispute); and (3) opinion leaders were major spreaders of disinformation among far-right users, as they reinforced hyperpartisan content and became key actors in the discursive struggles (and thus, reinforced the dispute).
