Designability of the Thought OS: A Theory of Structural Presentation via Jump Design ―Thought OS Trilogy Part 2: A Theory of Structural Design―

This paper presents the Thought Operating System (Thought OS) not merely as a cognitive model but as a reproducible structural design technique. While the previous preprint (2025-27) demonstrated that AI's Chain-of-Thought (CoT) responses emerged from reacting to human-provided structural prompts, this work investigates whether such structures can be intentionally designed.By formalizing the six principles of Mindflight Cognition and the seven capabilities of Structural Quotient (SQ), the paper identifies design rules that reliably induce cognitive leaps. It further analyzes the internal composition of jump-design templates, compares successful and failed designs, and outlines educational implementations and AI collaborative applications. Ultimately, this work positions Thought OS as an operable system for structuring meaning, redefining “thought” itself not as a record of contemplation but as a deliberate act of structural presentation. The paper proposes a new vision of thought as design.
