Why Gen Z Is Fragmenting: Disintegration and the Rise of Identity Disorders

This paper argues that the rise of identity disorders in Gen Z is not a psychological anomaly but a structural consequence of developing in a disintegrated environment. Identity formation requires stable boundary conditions—coherent communities, predictable roles, slow information, and consistent feedback loops. These conditions collapsed during Gen Z’s developmental window, producing an environment that no longer supports identity convergence.The paper formalizes the mechanism of disintegration as the loss of boundary conditions, the collapse of coherent feedback, and the saturation of high‑entropy information. It shows how these environmental failures generate identity instability, cognitive fragmentation, and emotional volatility as structural outcomes rather than individual deficits.Gen Z represents the first generation to experience identity formation inside a partially collapsed environment; Gen Alpha develops entirely within it. Their patterns reflect a broader dimensionality shift in which the environment becomes high‑dimensional, fluid, and continuously reconfiguring. In such conditions, traditional forms of identity cannot stabilize. The paper situates this generational crisis within a larger theoretical framework, including the principle of “evolution without environment,” where systems that depend on stable constraints cannot develop when those constraints dissolve.The result is a unified account of why identity disorders are rising, why they appear generational rather than individual, and why the crisis intensifies in younger cohorts. The paper concludes by outlining the implications for mental health, education, and institutions, and argues that stability must now be intentionally constructed rather than inherited.
