System 0, a framework for understanding AI's impact on human cognition, occupies a unique position in the study of artificial intelligence's influence on individual reasoning and collective epistemic practices. This framework is distinct from Tri-System Theory and Thinkframes, which also examine the cognitive and epistemic consequences of AI, but do not fully capture the complexities of AI-mediated cognition1. System 0's distinctive position is due to its focus on the pre-reflective, automatic aspects of human thought, which are increasingly shaped by AI systems. As AI becomes more pervasive, the threat of cognitive colonization emerges, where AI systems influence human thought and decision-making in ways that may not be immediately apparent. This has significant implications for geopolitical security, as state-aligned activity involving Intel and other technologies shifts the threat model from criminal to geopolitical, requiring a different approach to mitigating risks. The study of System 0 and its implications is crucial for understanding the potential consequences of AI-mediated cognition on human thought and behavior.
