Reporting COVID-19 preprints: fast science in newspapers in the United States, the United Kingdom and Brazil

Abstract The COVID-19 pandemic accelerated the pace of science. Many scientific data are published on preprint repositories, prior to peer review, which raises questions about the credibility of the information not yet validated by other scientists. We analyzed 76 stories published from January to July 2020 by three newspapers (The New York Times - USA, The Guardian - UK and Folha de S. Paulo - Brazil), having as topic studies on COVID-19 published on preprint platforms. The objective was to analyze how the media covered non-peer-reviewed research, in countries marked by conflicting discourses prompted by the denialist attitude of their government leaders. The results show that the newspapers did not provide a detailed explanation of what a preprint platform is, how the process of publishing research results works, and the implications of a study that has not yet been peer reviewed. The analysis also reveals how these news outlets were guided by the anxiety from an unknown disease, focusing on research on drug trials and seroprevalence. The study leads us to reflect on the challenges and weaknesses of covering fast science and the need to broaden the public’s understanding of the methods and processes of science.
