“Sophisticated non-kinetic threats, such as Chinese cognitive domain operations (CDO) and Russian active measures operations, define the contemporary global security landscape and pose significant challenges to national security policymakers in the United States. These adversarial capabilities transcend traditional military engagement, targeting the cognitive processes, beliefs, and unit cohesion of an opponent to achieve military objectives, often as a precursor to the onset of hostilities. By targeting the brain itself, adversaries can potentially alter US service members’ decision-makin or behavior, having a detrimental impact on their will to fight. Current understanding of brain sciences, the ubiquity of surveillance technology and big data, and algorithm-based evolving business and marketing models that condition human behavior are converging to shape global power competition in ways that may undermine the efficacy of assumptions about American power. As a result, foreign adversaries could subject the American population to a persistent state of cognitive manipulation and control. To prepare service members for this rapidly evolving environment, the Department of Defense (DoD) needs to adopt strategies to build critical thinking and individual resistance to persuasive cognitive attacks. This paper proposes a military training program that begins in recruit training and continues as part of regular professional military education based on information inoculation theory, a critical-thinking strategy analogous to medical immunization.”
