Augmented Individual Intelligence (AII): A New Mode of Hybrid Human-AI Cognition

Augmented Individual Intelligence (AII) is proposed as a bounded operational construct for studying sustained individual-level integration of adaptive artificial intelligence into reasoning, planning, reflection, and emotional regulation. The contribution is not the discovery of human–AI cognitive coupling as a new phenomenon, but a framework for making an increasingly common and theoretically diffuse phenomenon easier to identify, compare, measure, and critique. AII is characterized by continuity, bidirectionality, adaptivity, cross-domain application, and preservation of human agency. This manuscript situates AII within established frameworks—extended mind theory, distributed cognition, cognitive offloading, metacognition, and human–computer interaction—and specifies inclusion and exclusion criteria, observable indicators, developmental stages, validity concerns, and empirical study designs. Ethical, psychological, and social implications are discussed, with emphasis on scientific usefulness, defensible novelty, and responsible boundary-setting.
