- The primary paper being extracted — applies IIT 3.0 and 4.0 to LLM representation sequences derived from ToM test data to investigate whether consciousness phenomena can be observed.

cosine ≥ 0.65 · no typed edgeEntities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.
- Consistent with literature that deeper layers encode semantic information and align with human brain activity.
- The core phenomenon studied: the ability of LLMs to evaluate and revise their own reasoning.
- Interpretation of the layer-by-layer PCA visualizations showing linear structure emerging in early-middle layers
- The finding that interpretable concepts including character traits are encoded as linear directions in transformer residual streams
- High-dimensional vectors produced at each transformer layer for each input token; the primary substrate analyzed in this study.
- Theoretical interpretation of antipodal alignment and misalignment phenomena in PCA visualizations
- Tendency for models to get lost in roleplay or doom spirals, mitigated by expanded awareness.
- The ability of LLMs to monitor and evaluate their own reasoning, closely related to reflection.
