<p>Cognitive warfare has emerged as a critical domain in modern conflict, targeting the human mind through sophisticated psychological, informational, and neurological tactics, techniques, and procedures. This article examines how human perception, decision-making, and behavior are manipulated by states (non-state entities) to achieve strategic objectives, taking advantage of advances in artificial intelligence (AI), neurotechnology, and data analytics. Drawing on recent interdisciplinary research, the authors define cognitive warfare, detail its operational mechanisms, and assess its implications for individual autonomy and societal stability. The integration of AI-driven disinformation and neurotechnological tools amplifies the impact of cognitive warfare and poses unique ethical and security challenges. At the same time, the authors highlight the urgency of developing countermeasures to protect cognitive integrity in an increasingly contested digital landscape. In this regard, Christian theological anthropology can help. An effective defense against the operational mechanisms of cognitive warfare requires strengthening the human intellect’s and will’s natural inclination to seek truth and achieve goodness. This is accomplished through the practice of moral virtues.</p>
