'Supported and edited by excellent and up to date experts, this handbook is a most timely and highly pertinent contribution to a multidisciplinary and comprehensive understanding of one of the core challenges for our present and future security in freedom and prosperity. It should be used as a core reference for all academic and operational endeavours in this field.'Gerhard Conrad, Former Director of the European Union Intelligence Analysis and Situation Centre (EU INTCEN)'Like nuclear war shaped the XX century, hybrid and information wars will shape the XXI century. On the battlefield and in the AI labs, shaping politics and public opinion, the forces of disinformation threaten freedom and human rights. This book is a powerful handbook for leaders, scholars, and citizens eager to defend democracy.'Gianni Riotta, Princeton University, USA'The book makes a useful contribution to the discussion on the complex and vexing subject of disinformation—“false information that is knowingly distributed” (283)—and similar malign government efforts to deceive.'Michael J. Ard, Johns Hopkins University, Studies in Intelligence Vol. 68(1), March 2024'Even though disinformation is a complex phenomenon and a truly interdisciplinary field of study, the authors of the book have succeeded in recalibrating the analysis toward intelligence and security studies. Throughout the book a broad set of terminology – disinformation, misinformation, mal-information, etc. – is used to convey various research angles, leaving the authors the freedom to set their own definitions for central concepts.'Anna-Maria Osula, Journal of Baltic Studies, 55:3, 700-702, July 2024
