Abstract / Summary
Abstract This study introduces the Principle of Conditional Cultural Adaptiveness, establishing that the evolutionary performance of cultural strategies depends strictly on environmental state variables and shifts through equilibrium migration as those macro-conditions change. Modernity is formally conceptualized not as cultural erosion, but as equilibrium migration between state-dependent optima. Existing scholarly interpretations of Javanese maternal domesticity and the construct of kanca wingking frequently emphasize patriarchal gender hierarchies, symbolic cosmology, or moral norms without formally modeling how domestic practices dynamically adjust to resource volatility, environmental hazards, and shifting household bargaining power. We develop an environment-dependent game-theoretic frame work linking selected maternal instructions to material resource allocation, homeostatic regulation, risk management, health capital investment, cultural information transmission, and costly signaling. By integrating ethnographic philology with evolutionary game theory, bargaining theory, dynamic optimization, and eco-evolutionary feedback modeling, this research provides a formal computational social science framework for representing cultural persistence and transformation while explicitly differentiating stable household equilibria from equitable distributions of welfare.
