“It’s true! I saw it on WhatsApp”: Social Media, Covid-19, and Political-Ideological Orientation in Brazil

The Covid-19 pandemic in Brazil was widely affected by politics and the population’s consumption of information is fundamental to understanding the situation. This study aimed at understanding the relationship between political-ideological markers, consumption of information, and preventive practices during the pandemic. We conducted an online survey with 1,328 Brazilians who answered a questionnaire about authoritarianism, conservatism, political orientation, trust in social media, and preventive practices during the pandemic The results indicate that right-wing and centrist individuals, with higher authoritarianism or higher conservatism scores, put significantly more trust in the information about Covid-19 conveyed through WhatsApp and less trust in the information conveyed through traditional media, in comparison with left-wing individuals or individuals with low scores for these factors. Additionally, these elements were closely associated with worse practices concerning the use of masks, practices of social distancing, and the intention of being vaccinated. The findings warn of the impacts of fake news in health practices during the pandemic.
