Titre : Concealment in cognitive warfare: between saturation, strategic invisibilisation and systemic deception Auteurs : Arnaud de Morgny, Revue : Cognitive Engineering Numéro : Issue 1 Volume : 9 Date : 2026/02/4 DOI : 10.21494/ISTE.OP.2026.1411 ISSN : 2517-6978 Résumé : Cognitive warfare aims at shaping the adversary’s thinking by altering mental representations. In this context, concealment is not merely a tactical option but a structural feature of cognitive action. Operating at every stage of the cognitive chain - from raw data to actionable knowledge - it enables the attacker to remain invisible while manipulating the target’s interpretive processes. This article analyzes cognitive concealment mechanisms through a systemic lens: information overload, strategist invisibility, indirect action through mediating agents, classical forms of ruse such as Greek mètis, and modern doctrines like maskirovka. The study models the strategic and psychological impacts of concealment, with emphasis on ethical and doctrinal implications. Éditeur : ISTE OpenScience
