Post-truth and disinformation in the digital age: towards a new normative paradigm?

Abstract

This article analyzes how post-truth has transformed the way we consume, validate and share information, undermining critical thinking. Objectivity has been replaced by discourses based on emotions and beliefs, driven by social networks and algorithms that reinforce pre-existing opinions and limit rational deliberation. It is emphasized that post-truth is not a casual phenomenon, but a strategy of manipulation through information bubbles and echo chambers, where opinions are accepted without question. In this context, the Philosophy of Law warns about its impact on fundamental rights and the rule of law. The key to confronting disinformation is not only normative regulation, but the promotion of critical thinking to resist digital manipulation.
