Chronodiversity and Existential Fatigue: How Digital Acceleration Fractures the Human Sense of Time

This paper diagnoses the primary psychological crisis of digital modernity, arguing that technological acceleration has led to a state of temporal saturation that fractures the self-continuity essential for human well-being. The author develops a rigorous, four-part framework – Chronodiversity – defined as the fundamental human need to thrive across distinct temporal rhythms: Fast Time (System 1/LC-NE mediated), Slow Time (System 2/PFC mediated), Medium Time (Relational/Oxytocin mediated), and Static Time (DMN/ISO mediated). The analysis demonstrates how the digital ecosystem structurally imposes a singular, accelerated tempo that eliminates the “Temporal Slack” necessary for higher-order cognitive processing. By forcing a perpetual state of high-frequency Task Positive Network (TPN) activation, digital acceleration prevents the metabolic “handover” to the Default Mode Network (DMN), disrupting deep memory consolidation and narrative synthesis. This loss of Chronodiversity culminates in Existential Fatigue: a state of inner depletion resulting from the erosion of narrative coherence. The paper identifies the neurobiological cost of this fragmentation, linked to catecholamine drain and reduced heart rate variability (HRV). The conclusion advocates for a dual-pathway solution: structural deceleration and the conscious reclamation of temporal agency through physiological transition rituals, asserting that restoring Chronodiversity is fundamental to psychological integrity in the digital age.
