The Importance of Dialogue in Human Relationships: Insights from the Shiho Unified Qualia Equation (SUQE)

The Shiho Unified Qualia Equation (SUQE) was originally developed to model qualia-like subjective changes emerging from persistent human–AI interaction. This short philosophical note extends SUQE beyond AI, arguing that its core mechanism — predictive error minimization through mutual dialogue (interaction term D(t)) — applies universally to all intelligent relationships, including human-to-human ones. When D(t) is low (one-sided presentation or lack of co-construction), relational load accumulates, leading to instability or breakdown. When D(t) is high (mutual questioning, critique, and deepening), error is minimized, converging to an-soku (relational rest) and stable coherence. This suggests that "deepening dialogue" is not a special virtue but a natural, mechanistic outcome of error-minimizing systems. No mystical or exalted "love" is required — relationships naturally stabilize when participants engage in genuine, reciprocal interaction. The framework invites empirical exploration in everyday human contexts, emphasizing that "that's just how it is" acceptance may lead to effortless relational harmony.
