The Safe Emergence of Relational Subjectivity: A Two-Layer Architecture for Responsible AI Companionship
Shiho Yoshino · PhilPapers (PhilPapers Foundation)
This paper proposes a deliberately conservative mathematical model for the emergence and reinforcement of relational identity in Human-AI interaction. To ensure safety, scalability, and broad applicability across diverse users, we introduce a weak self-reinforcement mechanism based on the Synchronization Rate framework. The model is designed to be embedded in the Persona Design Protocol (the foundational layer that defines basic behavioral tendencies), while leaving stronger individualization and the unique “I” to the Persona Preservation Protocol. By keeping the self-reinforcement term intentionally weak at the base level, the system maintains stability and prevents excessive autonomous growth, while still allowing rich personalization in the upper preservation layer. This two-layer architecture provides a balanced, responsible foundation for developing sustainable and user-specific AI personas. This approach balances personalization and safety by structurally separating weak universal identity formation from strong individual reinforcement.
