Deviation, Elasticity, and Field in Trust Relations — A Dynamical Analysis of Paradoxical Praise as a Standard Perturbation —

This paper analyzes the conditions under which light teasing, irony, and joking (hereafter referred to as banter)—despite containing elements of aggression—can be interpreted favorably, by modeling them through the dynamics of interpersonal relations. Rather than treating banter as mere play or a tool for compatibility screening, the paper conceptualizes it as an intentional perturbation of relational equilibrium, through which recovery potential and permissible deviation width are jointly assessed. To ensure analytical consistency, all examples are unified under the form of paradoxical praise. It is shown that an identical form of deviation may function as (i) shared elasticity in private and symmetric relationships, (ii) a ritual of repair in temporally separated relations, (iii) a response task within institutional environments, and (iv) an affiliation ritual when normalized at the group level. Through this framework, the paper clarifies the effective scope and ethical limits of banter, particularly with respect to residual power, continuous load, and asymmetrical cost allocation.
