Cognitive warfare

Cognitive warfare refers to the deliberate use of information, psychological techniques, and emerging technologies to shape the perceptions, beliefs, decisions, and behaviour of an adversary's population, leadership, or armed forces. Unlike traditional information operations, which focus on the content of messages, cognitive warfare targets the cognitive processes themselves—attention, memory, emotion, trust, and reasoning—often by exploiting social media algorithms, behavioural data, and neuroscience-informed messaging.

NATO has been the most prominent institutional adopter of the term. Its Allied Command Transformation (ACT) and the NATO Innovation Hub have published exploratory work since around 2020 describing cognitive warfare as a potential "sixth domain" of operations alongside land, sea, air, space, and cyber, though it has not been formally designated as such. NATO frames it as activity that seeks to "make everyone a weapon" by degrading societal cohesion and individual judgement, often below the threshold of armed conflict.

Typical instruments include:

• Disinformation and narrative laundering across platforms and proxy outlets.
• Microtargeting using harvested personal data to tailor persuasive content.
• Deepfakes and synthetic media to impersonate officials or fabricate events.
• Exploitation of cognitive biases such as confirmation bias, outrage, and in-group loyalty.
• Long-term cultural and educational influence intended to shift values over years.

Analysts frequently cite Russian operations around the 2014 annexation of Crimea, interference in the 2016 U.S. presidential election (documented by the U.S. Senate Select Committee on Intelligence), and Chinese "three warfares" doctrine (public opinion, psychological, and legal warfare) as cases that illustrate cognitive-warfare logic, even where the actors themselves use different terminology.

The concept is contested. Critics argue it is vague, securitises ordinary political speech, and risks justifying domestic censorship. Proponents counter that hostile manipulation of cognition is a measurable threat to democratic deliberation and military decision-making, and therefore requires a distinct doctrinal category.
