Disinformation networks: the virality of fake news, echo chambers and algorithmic manipulation

Abstract

Misinformation, exacerbated by social media and the use of algorithms, has become one of the main dangers facing contemporary societies as we know them. It clearly undermines everything that makes us human. In the post-truth era, emotions displace facts and lies are more likely to go viral than the truth. This phenomenon is reinforced in digital echo chambers, where users are exposed only to content that confirms their beliefs, strengthening polarization and reducing their critical thinking skills. Added to this is Artificial Intelligence, which achieves an experience of veracity through hyper-realistic and viral content. In the face of this, the development of critical thinking in the post-truth era is an act of resistance against noise and manipulation. Giving up on it jeopardizes the truth itself and undermines democracy and freedom.
