The concept is implicit throughout Giddens's work on self and identity but is most fully developed in Modernity and Self-Identity (1991). It draws on hermeneutic traditions from Paul Ricoeur and narrative psychology while connecting to Giddens's structural analyses of reflexivity and ontological security.
The ordinary operation of narrative coherence is incremental. One adjusts one's self-narrative to accommodate new experiences, but the adjustments modify the plot without challenging the genre. The AI transition challenges the genre itself. The story of the professional self that used eight years of coding practice as its foundation cannot simply add a chapter about AI adoption; it must be rewritten in a genre that does not yet exist.
The threat operates through the de-functionalization of the past. The engineer's eight years of patient practice were the foundation on which her present competence rested and from which her future development would proceed. AI does not make those years worthless in any absolute sense — the judgment and taste they produced remain valuable — but it makes them non-functional as foundation in the way they had been. The past no longer supports the present in the specific way the narrative had been built to assume.
Without a functional relationship to the past, the present loses its moorings. The self-narrative fragments. The individual continues to have memories, experiences, capacities — but they no longer compose a single continuous story. This is the phenomenology of ontological crisis at the narrative level: not loss of memory but loss of the structuring principle that had organized memory into biography.
The concept synthesizes hermeneutic work on narrative identity (Ricoeur, MacIntyre), sociological work on biography (Anselm Strauss, Catherine Kohler Riessman), and Giddens's own framework of reflexive self-monitoring. It received its fullest Giddensian articulation in Modernity and Self-Identity.
Temporal integration. Coherence is achieved through the meaningful integration of past, present, and future into a single continuous story.
Experienced authorship. The narrator must experience the story as her own — not imposed from outside but authored, revisable, hers.
Incremental normal operation. Under ordinary conditions, narrative coherence is maintained through small adjustments that modify plot without challenging genre.
Genre challenge. The AI transition challenges the genre itself, requiring rewriting rather than editing.
De-functionalization threat. The transition's specific threat is making the past non-functional as foundation, disrupting the temporal integration on which coherence depends.
Whether narrative coherence is a universal requirement of human flourishing or a specifically modern-Western demand is debated in cross-cultural and comparative psychology. The question matters for AI-transition responses: if the demand is culturally specific, then some cultural traditions may have more resources for navigating narrative fragmentation than others.
