This article proposes the Boundary State Transition Principle within the framework of Social Relativity Theory (SRT). It argues that structural decisions and sudden shifts in position are not random events, but the outcome of accumulated forces that surpass a system’s critical threshold. The model defines key variables: accumulated structural force (F), structural inertia (I) and boundary threshold (B), determining that system transition (ΔS) follows a binary condition either 0 or 1. While the accumulation process is continuous, the resulting state change is discontinuous. The study demonstrates that instantaneous decisions are the culmination of long-term structural accumulation reaching a critical point, rather than spontaneous or uncaused phenomena. This framework contributes to the understanding of power dynamics and structural transformations within social systems.
