Cognitive Warfare
Cognitive warfare is an evolving and contested security concept describing coordinated activity intended to influence, disrupt, degrade, or control how people or institutions perceive, interpret, decide, and behave. It may combine information operations, psychological methods, cyber capabilities, data, technology, and other instruments to exploit cognitive and social vulnerabilities for strategic advantage.
The term does not have one universally settled legal or policy definition and should be used carefully. It overlaps with influence operations, psychological operations, information warfare, and hybrid threats, but places particular emphasis on human cognition, decision-making, trust, and the wider social systems through which people understand reality.
Diplomatic institutions can be both observers and targets of attempts to distort judgment, polarize publics, weaken alliance cohesion, or create distrust in authoritative information. The concept can help examine combined pressure across information and technology systems, but overuse risks securitizing ordinary persuasion, disagreement, political communication, or cultural influence.
Cognitive-warfare analysis appears in defense and security planning, influence campaigns, information and psychological operations, deceptive digital content, microtargeting, cyber-enabled manipulation, attacks on institutional trust, and coordinated efforts to affect how leaders, personnel, or populations interpret events and make decisions.
