A Structural Redefinition of Luck: Transforming Randomness into Meaning through a Cognitive OS

This paper aims to structurally redefine the phenomenon commonly referred to as "luck."While often used in everyday language, the concept of luck remains vague and under-theorized.Using the perspective of Core-Belief Structural Theory (Kakushin Kōzōron), the paper presents a two-layered model of luck:the first layer as probabilistic events, and the second as structural meaning-making. Not all coincidences become luck; only when a person recognizes meaning, assigns value, and acts on it does luck emerge.We analyze this process through the lens of Structural Quotient (SQ),composed of structural perception, core-value-oriented filtering, and cognitive flight (Hishō-Ninchi).The paper further explores how such cognitive structures can be trained and how luck becomes a partially reproducible skill.We argue that luck is not a mystery but an expression of structurally organized intelligence.
