Abstract
<jats:p>The search for reality in the 21st century has become a task of unprecedented complexity, marking the dawn of the “Information Disorder” era where trust in global information ecosystems is being deliberately eroded. By 2025, estimates suggest that up to 62% of online content may be false or artificially generated, exposing 86% of the population to deceptive narratives. This book, The End of Reality: Disinformation and the Fact-Checking Era, serves as a comprehensive cartography of this landscape, integrating perspectives from 75 internationally renowned scholars across 20 countries. Through six sections, the authors discuss the philosophical foundations of our post-truth condition, exploring concepts like “I-pistemology”, where subjective life experience replaces institutional expertise. The volume unmasks the “synthetic illusions” of Large Language Models and the rise of “synthetic friends”: AI companions that create impenetrable epistemic cocoons. From the information warfare in geopolitical conflicts to the visual distortions during natural disasters like the 2024 DANA foods in Spain, this work provides a multidisciplinary exploration of how truth is contested. It goes beyond simple debunking to propose new technological and collaborative frameworks for verification, such as the MonitorIA project for Telegram and the DISINFOX platform. By addressing the “human factor” through cognitive resilience models like the “Wave and Wall”, this book offers a roadmap for navigating an ecosystem where the distinction between truth and synthetic illusion has become a defining battlefeld of our time. Finally, these chapters remind us that reality is a collective achievement requiring constant defense and ethical stewardship of our informational behaviour.</jats:p>
