Identity threat and defensive engagement describe a class of behavioral responses that emerge when users perceive their established identity within a digital system as being at risk. Unlike dissatisfaction-driven churn, identity threat often produces increased engagement, as users act to protect, restore, or stabilize their self-representation. This paper analyzes defensive engagement not as emotional overreaction, but as a rational adaptation within identity-invested systems. By examining how status changes, rule shifts, rebalancing, or visibility loss activate identity defense mechanisms, the analysis positions identity threat as a…

Self-concept drift describes a gradual, often imperceptible process through which prolonged interaction with digital systems reshapes users’ self-perception, preferences, and behavioral norms. Rather than users merely expressing pre-existing identity within a system, the system increasingly participates in defining that identity. This paper analyzes self-concept drift as a long-horizon outcome of engagement architectures that reward alignment, consistency, and adaptation. Positioned at a meta-systemic level, the analysis shows how digital products do not simply retain users, but progressively recalibrate who users believe they are, how…

Identity loss aversion describes a psychological condition in which users prioritize the preservation of an established digital identity over the pursuit of improved utility, satisfaction, or alternative options. Extending classical loss aversion from objects and outcomes to the self, this paper analyzes how identity—once externalized into digital systems—becomes a protected asset. The analysis positions identity loss aversion as a convergent outcome of long-term engagement architectures, where avatars, narratives, reputation, emotional labor, and self-concept drift collectively transform disengagement into a perceived personal loss.…

Narrative lock-in and story-driven retention describe a terminal engagement architecture in which digital systems retain users by embedding interaction within a coherent, ongoing personal story. Unlike reward-based or identity-fragment mechanisms that operate on discrete psychological levers, narrative lock-in integrates time, effort, identity, reputation, and emotion into a single autobiographical frame. This paper positions narrative lock-in as the closing layer of identity-driven design: the point at which engagement is sustained not by incentives or pressure, but by the need to preserve narrative coherence. Disengagement becomes…
