Suicide as a Structural Failure of Psychological Feedback Integrating Contemporary Suicide Frameworks Through a Dual-Singularity Architectural Model

Contemporary suicide research has generated multiple empirically supported frameworks emphasizing cognitive vulnerability, interpersonal disconnection, stress–diathesis interaction, psychiatric pathology, and biological dysregulation. These approaches successfully identify population-level correlates and proximal risk processes, yet none fully accounts for a phenomenological feature consistently reported across suicidal states: the perceived impossibility of psychological continuation (Shneidman, 1993; Turecki & Brent, 2016). This paper advances an architectural reframing of suicidality as a failure of psychological feedback rather than as a deficit of coping, morality, rationality, or distress tolerance. Drawing on the Multidimensional Architectural Framework for Psychological Organization, the Dual-Singularity Model of Human Psychological Life, and the Five-Domain Architectural Framework for Psychological Pathology (Chu Nguyễn Đức Dũng, 2025a, 2025b, 2025c), suicidality is conceptualized as a boundary condition in which biological existence persists while alignment and sustainability through time collapse. Existing suicide theories are re-examined within this architecture, clarifying their empirical contributions while identifying a shared structural omission: the absence of an explicit account of how psychological systems lose access to viable continuation. By locating suicidality at the level of feedback collapse between existence, agency, and temporality, this model integrates contemporary findings while preserving phenomenological accuracy and avoiding moral, cognitive, or diagnostic reductionism.
