Disseminação da desinformação on-line & tecnologias de informação e comunicação

Abstract

Studying the phenomenon of online misinformation and its relationship with communication and information technologies (ICTs) is both essential and challenging, especially in the contemporary context where social networks become vehicles for both information and manipulation. This work investigates how ICTs, particularly during the covid-19 pandemic, influenced the proliferation of misinformation and the impacts it had on society, public health, and democracy. Using a critical approach grounded in Andrew Feenberg’s Critical Theory, I analyze the connection between the Internet, politics, and surveillance capitalism, highlighting the erosion of democratic debate amid the rise of data as a primary economic resource. I also explore the role of algorithms and echo chambers in spreading misinformation, examining how these mechanisms contribute to polarizing discussions and solidifying false beliefs. The study includes an analysis of social media posts from major news outlets, such as O Globo and UOL, which attempted to debunk false information related to covid-19. The behavior of users in response to these posts, their reactions, comments, and overall engagement were analyzed, revealing the challenges that media organizations face in effectively combating misinformation. The research found that online misinformation not only destabilizes public health efforts but also amplifies distrust in institutions and traditional journalism. Finally, I suggest that more effective strategies for combating misinformation need to consider not only the content but also the context in which information is received and interpreted. I propose guidelines for public policies aimed at mitigating the effects of misinformation and fostering a healthier and more constructive digital environment. However, the complexity of the issue requires further future research to deepen understanding.
