Cognitive Warfare and the Indo-Pacific

Jon Reisher 

Editor’s Note: This article was submitted as part of the Irregular Warfare Initiative’s 2025 Writing Contest, in which authors were invited to explore how the United States and its partners can use irregular warfare to strengthen security cooperation, build trust, and enhance resilience among Indo-Pacific nations. This article stood out for its innovative framing of cognitive warfare as a tool of deterrence and alliance-building, and for its practical recommendations on how small Indo-Pacific nations can leverage information operations to uphold international norms. We have edited the piece after its selection.
“Psychologically, the PRC is trying to cause mental disarray and confusion, in order to weaken fighting will and determination to defend ourselves.”

The balance of the modern global information environment has become algorithmically biased, with social media platforms tailoring content to users’ preferences and reinforcing their pre-existing beliefs. By isolating users in personalized filter bubbles, these algorithms amplify confirmation bias and cultivate increasingly polarized online echo chambers, distorting users’ perceptions of reality and fueling societal division—conditions the People’s Republic of China (PRC) has learned to weaponize.
