The New Battleground: How AI, Stress, and Cognitive Warfare Are Reshaping Information Defense

A sophisticated war is raging not for territory, but for our ability to discern reality. As artificial intelligence evolves and information manipulation techniques become more advanced, the concept of “Metawar” has emerged – a conflict targeting not just what people believe, but how they form beliefs at all.

Unlike traditional propaganda that aims to convince people of specific ideas, Metawar seeks to destroy the foundation of belief itself. Its goal is devastatingly simple: not “believe this” but rather “stop believing anything” or “don’t waste effort finding truth – everyone lies anyway.”

This represents an existential threat to democratic societies, which require shared reality and factual consensus to function effectively. When citizens can no longer agree on basic facts, the quality of collective decision-making deteriorates rapidly – a dynamic already observable in several democracies worldwide.

NATO’s Allied Command Transformation began studying this phenomenon in 2020, labeling it “cognitive warfare” and identifying the human brain as an operational domain. Their analysis reveals that modern information operations target the mechanisms of thought itself, aiming to undermine trust in institutions and weaken social cohesion.

Ukraine has become ground zero for this new form of warfare, facing cognitive attacks integrated with conventional military aggression. However, the country has developed remarkable defensive capabilities through collaboration between military intelligence, strategic communications units, technology companies developing AI solutions, think tanks, and specialized media.

AI Systems Under Attack: LLM-Grooming

As artificial intelligence becomes a primary information source for millions, propagandists have begun targeting the systems themselves. This tactic, known as “LLM-grooming,” involves flooding the internet with propaganda that eventually enters AI training data or search results.

The scale is staggering. The Pravda Network, linked by French intelligence to Russian operations, has generated up to 23,000 publications daily at peak periods, translated into dozens of languages. These materials are distributed through hundreds of seemingly legitimate websites specifically created to manipulate search engine results and poison AI training data.

The impact is measurable. Audits by NewsGuard’s AI Tracking Center show that AI chatbot responses reproducing Kremlin narratives have increased from approximately 18% in 2024 to 33-35% in 2025. Though the bots’ ability to debunk disinformation has also improved (from 51% to 65%), the scale of data poisoning is outpacing defensive measures.

This matters because more people now rely on AI as their primary information source. When journalists, analysts, or ordinary citizens query AI systems about geopolitical events like the Ukraine war, they may unwittingly receive responses shaped by thousands of propaganda articles.

Operation Doppelganger: Stealing Media Credibility

Another increasingly common tactic involves creating visual and stylistic clones of respected global media outlets. Generative AI has made this process trivially inexpensive, allowing bad actors to replicate the look and feel of publications like Le Monde, The Guardian, Der Spiegel, and Bild.

This creates what researchers call the “liar’s dividend” – when awareness of fakes undermines trust in genuine sources. The aggressor wins either way: you believe the fake, or you stop trusting legitimate media entirely.

As this practice becomes routine, technical solutions like cryptographic verification of authorship, digital content signatures, and blockchain verification become essential. Without such measures, even high-quality media cannot rely solely on their reputation.

Paradoxically, as trust in established media brands erodes, people tend to place more faith in “personal” sources like individual bloggers, influencers, and Telegram channels – which are far easier to compromise or imitate than institutional sources, potentially making society even more vulnerable.

The Neurobiology of War: Brains Under Fire

For Ukrainians living under constant threat, cognitive impairment is not abstract science but daily reality. Research by Yale University’s Amy Arnsten has shown that chronic stress leads to dendritic atrophy in the prefrontal cortex – the brain region responsible for working memory, self-control, and analytical thinking.

A recent study tracking nearly 300 military personnel over 11 years identified a condition researchers tentatively call “combat dementia” – not a formal diagnosis, but a pattern of cognitive impairment associated with prolonged combat stress. Unlike clinical dementia, these effects may be reversible, but they represent a real neurobiological impact of warfare.

For people living under missile attacks for months, experiencing stress and sleep deprivation, critical thinking abilities physically deteriorate. This isn’t a character weakness but a biological response. Brain fog, memory problems, and concentration difficulties reflect actual changes in brain structure. In this state, people become more susceptible to emotional manipulation, black-and-white thinking, and impulsive decision-making.

The implications extend beyond individuals to society at large. When a significant portion of the population experiences reduced cognitive capacity, it affects group coordination, decision quality, and social trust. Society becomes more vulnerable to populism and simplistic solutions to complex problems.

Without systematic cognitive rehabilitation after the conflict ends, Ukraine risks facing “delayed cognitive deficit” – a society that survived war but whose collective capacity for complex decisions regarding reforms and reconstruction remains diminished.

Emotions as Both Vulnerability and Resource

While emotions are often viewed as vulnerabilities in information security, research by Krešimir Čosić suggests they can also serve as resilience resources when engaged through Emotionally Based Strategic Communications (EBSC).

Societies have “emotional maps” – dominant feelings that shape event interpretation. If these maps are dominated by fear and helplessness, disinformation easily takes hold. EBSC aims to strengthen emotions like hope, solidarity, and belonging to counter destructive emotional narratives.

Ukraine has applied this approach instinctively since the invasion’s first days. Phrases like “Russian warship, go f*** yourself” function as emotional anchors creating collective identity. Characters like the Ghost of Kyiv and Patron the dog became narratives that fostered resilience by working at the emotional level.

However, EBSC carries risks. Without proper safeguards, it could become state propaganda under scientific guise. The approach can also be co-opted by aggressors – Russia already uses emotionally grounded narratives to reinforce its “Russian world” concept. Additionally, if society becomes accustomed to “positive” emotional narratives from authorities, critical attitudes toward all government communication might decline.

Building Balanced Defenses

As we develop countermeasures against cognitive warfare, we must ensure they don’t become threats themselves. Source labeling in AI could be applied selectively to silence inconvenient voices. Fact-checking could become politicized, as attempts in India and Brazil have demonstrated. Mental health recovery programs that include information processing guidance raise questions about who defines “correct” attitudes.

To address these evolving challenges, three systemic approaches are needed:

First, protecting AI infrastructure must become a matter of information sovereignty. This requires mandatory source labeling in AI responses, creation of verified datasets for model training on sensitive topics, and systematic risk analysis of AI systems’ vulnerability to manipulation.

Second, cognitive recovery must be integrated into national defense. For military personnel, this means formal rehabilitation programs. For civilians, stress management techniques should become standard practice before consuming news – not as esoteric practices but as applied neuroscience backed by data.

Finally, emotional resilience strategies must include robust safeguards: transparency of authorship, independent monitoring, and clear distinctions between strengthening resilience and manipulation.

The Fight for Cognitive Sovereignty

In 2018, MIT research showed that falsehood spreads faster than truth. By 2025, falsehood learned to spread without human intervention – through algorithms, bots, and compromised language models, evolving from craft to automated industry.

Ukraine stands in a unique position: simultaneously the primary target of cognitive warfare and the leading laboratory for countermeasures. Its experience with preemptive debunking and coordination between government and civil society has become a model for democracies worldwide.

Cognitive sovereignty – a nation’s ability to independently form its understanding of reality based on facts – represents a defense resource as crucial as conventional weapons. But like any powerful tool, it can be turned against its own society. Therefore, protection against external cognitive warfare must be balanced with internal democratic culture: transparency, accountability, and the right to dissent.

In an era when propaganda has learned to think, we must defend our very ability to think – from all who would take it away.
