Research Context This manuscript examines the structural role of human judgment in complex systems and proposes a conceptual framework in which human judgment functions as a structural boundary within high-complexity environments. In AI-mediated and automated decision environments, operational processes increasingly rely on algorithmic interpretation, distributed information flows, and large-scale system replication. While such systems improve efficiency and scalability, they also introduce structural challenges related to accountability, interpretability, and long-run governance stability. The study argues that human judgment cannot be fully replaced in complex and non-closure systems. Instead, human judgment operates as a stabilizing interface that constrains automated decision processes and maintains structural coherence within evolving technological environments.
