Observation of Structural Reasoning Stability in Long-term Human–LLM Interaction

Full Technical Report (DOI):https://​​doi.org/​​10.5281/​​zenodo.18672389

I have recently documented an observational case involving long-term interaction between a human user and a large language model (LLM), in which the apparent stabilization and hierarchical organization of reasoning structures was observed across temporally separated dialogue sessions.

Across multiple independent interaction sessions, conceptually similar reasoning patterns were observed to re-emerge over time. Notably, upon reappearance, these patterns appeared to undergo reorganization at a structural level, rather than at a purely representational or linguistic level.

In addition, certain evaluative tendencies and directional reasoning preferences appeared to exhibit relative stability across extended interaction periods.

At present, it remains unclear whether these observations reflect:

  • model-internal properties,

  • contextual dialogue accumulation,

  • user-side cognitive structuring,

  • or known in-context learning effects.

No claims of novelty, generalizability, or reproducibility are made in the associated report.

For analytical convenience, a provisional hierarchical classification was used to describe the observed reasoning patterns:

  • L1: Concrete case-level reasoning

  • L2: Abstracted tendencies

  • L3: Aggregation of abstract concepts

  • L4: Integrated synthesis

  • L5+: Formation of stable reasoning frameworks or evaluative criteria

These levels are heuristic and have not been mapped to any existing theoretical framework.

This observation may be consistent with multiple explanatory pathways, including:

(A) Alignment-related stabilization
Does prolonged interaction induce implicit adaptation of model responses to user-specific evaluative frameworks?

(B) Cognitive co-adaptation
Could the observed hierarchical structuring reflect externalization or co-construction of metacognitive processes through dialogue?

(C) Context-induced structural organization
Is the structural reorganization upon conceptual re-emergence sufficiently explained by known mechanisms of in-context learning?

Further empirical investigation may be required to determine the relative explanatory adequacy of these hypotheses.

Researchers interested in further examination under appropriate confidentiality arrangements are welcome to initiate contact regarding potential collaborative investigation.
