Como as ciências morrem? Os ataques ao conhecimento na era da pós-verdade

Translated title of the contribution: How sciences die? Attacks to knowledge in the post-truth era

Research output: Contribution to journalArticlepeer-review


In this article we analyze how the phenomenon of post-truth impacts public opinion through the creation of an environment hostile to critical thinking and scientific knowledge. Negationist and obscurantist movements attack democratic institutions and deny science, relativizing and pulverizing the notions of truth and objectivity, promoting distrust in the possibility of dealing with facts and not just narratives or versions. Through this historical and social background, we discuss the role of science studies and propose three levels of reaction; (a) An active role in public policies and educational strategies in science communication and scientific education, (b) revision of conceptual foundations in science studies and (c) defense of an image of science that rescues the notions of truth, fact and objectivity and reinforces science in its existential dimension and not only in an instrumental and utilitarian sense.
