This document explores the phenomenon of unwritten norms, or "normals," which exist across both natural and social dimensions. Unlike fixed regulations, these normals represent dynamic patterns that can be quantitatively modeled using the Gaussian distribution. The author argues that the peak of this curve serves as a temporary "standard" or "model" that shifts over time, challenging simplistic evolutionary interpretations based solely on chance and selection. This concept is further applied to human culture and consciousness, with a specific focus on linguistics. Language evolution is characterized by a tension between integrative tendencies, which facilitate wider communication, and inertial forces that preserve cultural continuity and literary heritage. Examples such as shifts in script or political resistance to alphabet changes illustrate how these norms operate. Language remains governed by such unwritten standards even without formal codification, oscillating between creative renewal and degradation into clichés. Ultimately, the text questions the underlying mechanisms that allow certain linguistic innovations to establish themselves as new, functional unwritten norms.
