nevarumai

Nevarumai is a term used in speculative fiction and associated philosophical discussions to describe a slow, insidious drift in personal continuity and memory. It refers to how remembered experiences, self-narratives, and decision-making patterns gradually diverge from present states, producing a sense of unreliability in self-perception without a clear external cause.

It has appeared in modern science fiction and thought experiments exploring aging, cognitive change, and the future of artificial intelligence. In many works, nevarumai is depicted as a nonlinear process that accumulates over time, challenging characters to align their past with their present and to confirm their own agency.

Characteristics commonly attributed to nevarumai include nonlinear accumulation, resilience to immediate correction, and a widening gap between current cognition and long-term records. In fiction and theoretical essays, triggers may include information overload, altered sensory input, or recursive self-referential processing. Diagnoses are described through longitudinal narrative coherence checks and cross-temporal log comparisons, used as thought experiments or plot devices.

Scholars discuss its ethical and philosophical implications, raising questions about identity continuity, autonomy, and the reliability of memory. Some critics argue that nevarumai risks pathologizing normal memory variability, while others see it as a useful framework for examining the fragility of self in aging, trauma, or interactions with advanced technologies.
