In the wake of the Facebook/Cambridge Analytica scandal, it is timely to review the state of the debate about the impact of data-driven elections and to identify key questions that require academic research and regulatory response. The papers in this collection, by some of the world’s most prominent elections researchers, offer that assessment.
This paper analyses the spread of misinformation in the context of 2018 Brazilian elections. We give a general overview of the Brazilian political context, its media ecosystem and the weaponisation of the country’s most popular messaging app, WhatsApp, as a political persuasion tool. The current architecture of the platform does not allow, once appropriated for purposes of election campaigns, users to notice or become aware that they are being monitored and managed.
