Will Circuit Activation Theory(WCAT)-Version 2.0

This white paper introduces the Will Circuit Activation Theory (WCAT), an original interdisciplinary framework bridging metacognitive psychology, neuroethics, developmental neuroscience, and the philosophy of free will. WCAT proposes a layered model of volition and meaning-processing circuits in the human brain, aiming to support the emergence of Homo Sapiens 2.0 — an ethically self-directed, cognitively sovereign human subject in the age of intelligent systems. Authored by Jiawei, an independent researcher based in China, this version (v2.0) formalizes the foundational theoretical structure and ethical implications of WCAT. This registration provides a timestamped public record to establish authorship and ensure intellectual integrity for global peer review and application. Key concepts include: System-1/System-2 neuromechanisms, memetic cultural conditioning, metacognitive circuit rewiring, and the Fourth Transition hypothesis. This work is part of an ongoing collaboration between human cognition and AI-assisted reasoning, under an evolving framework of trans-ethical symbiosis.
