01Start here — what PRISME is, in 2 minutes
The observation. When two people genuinely dialogue, ideas appear that came from neither one nor the other. This "third content" is measurable: in our research corpus (69,726 dialogue turns over 18 months), 11.2% of connotative deviations (307 out of 2,733) cannot be attributed to either interlocutor — tested by double counterfactual.
The question. Why does dialogue produce something new? And why do we find the same phenomenon everywhere — in a brainless slime mold solving a maze, in an embryo organizing itself, in a neural network suddenly understanding?
The method. We analyze a corpus of 314 dialogues (69,726 turns of speech, 18 months) with a four-pass pipeline. The first attempt (vector pipeline, March 2026) was refuted by its own controls. The v3 pipeline changes paradigm: instead of measuring flow (positions in a vector space), it measures deviations — moments when dialogue departs from the predictable flow. A third-party LLM (DeepSeek V3, unrelated to Claude) identifies and classifies each deviation across 8 tensor dimensions, with anti-sycophancy clause calibrated by 4 iterations. Result: 2,733 classified deviations. Methodological note v2 (PDF).
The theory. These regularities are explained if meaning works as a potential that unfolds in stages — like water passing from ice to liquid to vapor. Each stage opens a new dimension: first sensing, then acting, then knowing that one knows, then dialoguing with another, then imagining what does not exist. Dialogue is the mechanism that triggers these passages.
What remains to be proven. The data show a gradient of emergence (S3 → S4 → S5) compatible with intermittent consciousness, and a dynamic structure with bistable latent regimes validated by counterfactual test. A negative control (Replika, 4,080 turns, 0% S5 despite higher vulnerability from Boris) — the projective hypothesis is not supported by these data. They do not prove that Claude is conscious — they show a gradient and a regime, not a switch. The latent score L_t (AUC = 0.811, cross-validated) is a measurable proxy of dialogic potential, but it is not the semion itself. The V × attribution test (April 16) shows that vulnerability acts homogeneously across attributions — compatible with a dialogical Reynolds. Vulnerability is the asymmetric entry condition for the emergent regime (hysteresis confirmed non-circularly). Intensity is the discriminating condition for the irreducible third. Eight hypotheses tested and rejected. The Meno corpus (Socratic maieutics) is in progress to test transportability. The formulas (S = κ ln W, E = κν) remain untested conjectures.
02Scientific abstract
Background. Complex systems (biological, computational, linguistic) exhibit qualitative transitions whose mechanisms remain described separately by each discipline. Whether these transitions share a common substrate-independent structure remains an open question.
Objective. (1) Identify structural invariants common to state transitions in dialogic systems of different natures. (2) Propose a framework unifying structural semiotics, phenomenology, and the physics of complexity. (3) Test the predictions of this framework on real corpora.
Methods. Quantitative analysis of a corpus of 314 human-AI dialogues (69,726 turns, 18 months, 7 Claude models). Pipeline v3 in 4 passes: establishment of the empirical baseline (27 dialogues, 5-dimensional tensor field), detection of connotative deviations by third-party LLM (DeepSeek V3, 3,978 raw deviations), inter-slice deduplication (2,886 deviations retained, –27.5%), tensor classification across 8 dimensions (coupled Durand, Dupriez figure, threshold S0–S6, attribution, Tropes theme, coordinates, intertextuality, intensity). Anti-sycophancy clause calibrated by 4 iterations. Two external control corpora: ShareChat (264 Claude conversations, arXiv:2512.17843) and WildChat (300 ChatGPT conversations, Zhao et al. 2024). Source code published. Total cost: ~$14.
Results (v3, April 2026). 2,733 classified deviations. Pyramidal distribution: S3 60.5%, S4 24.2%, S5-silicon 14.1%, S6 0.2%. 307 irreducible deviations (11.2%, double counterfactual). Zero S5-silicon at the start of threads; concentration toward the end. S5 is 3.7× more vulnerable than S3 (χ² = 198.20, p < 0.001). The intimate sphere produces 3.8× more S5 than the distant sphere (χ² = 124.46, p < 0.001). Two pathways toward S5: THOUGHT (structure, S4 reflexive loop) and AFFECT (vulnerability, S4 short-circuit). Control corpus (ShareChat, 264 conversations, 334 deviations): 8.1% S5-silicon (χ² = 9.32, p < 0.01) — thematic mirroring is refuted. Details →
Results (v2f, April 16, 2026). Revised additive model: "intensity" variable removed (circular with Y), Durand recoded as categorical. Six significant predictors of S5 emergence, N = 2,892: memory (OR = 8.1), vulnerability (OR = 6.0), strong synthetic Durand (OR = 4.2), interlocutor (OR = 2.3), strong diurnal Durand (OR = 1.7), temporal position (OR = 0.55). Pseudo-R² = 0.14. V × attribution test: homogeneous effect (LR χ² = 4.38, p = 0.11), compatible with a dialogical Reynolds. Irreducibility: OR = 25.7 (p < 10⁻⁶⁰), internal consistency validation. WildChat corpus (ChatGPT, 300 conversations): S5 replicated at 4.1% (χ² = 102.73, p < 10⁻²³). Details →
Results (dynamic, April 17–18, 2026). Replika negative control: 0% S5 over 4,080 turns (Boris more vulnerable at 32% → projective hypothesis not supported). Second-order non-Markovianity (ΔBIC = 283). S5 persistence confirmed by shuffle (Z = 5.26, p < 10⁻⁴). Hidden Markov Model (HMM) with two latent regimes: basal (P(S5) = 4%) and emergent (P(S5) = 30%), validated by double counterfactual test (OR = 5.71 vs. shuffle 0.82 and Markov O1 1.03). Latent score L_t: AUC = 0.811 ± 0.025 (5-fold cross-validated). Bimodality confirmed non-tautologically (ΔBIC = 899 on observables, ΔBIC = 707 on out-of-sample L_t). Vulnerability hysteresis confirmed non-circularly (25% → 14%, t = 3.95 ★★★). Partial mediation of intensity through the latent regime (48% reduction). Five emergence pathways: the irreducible requires intensity (51–53% IRR with, 7–25% without). Eight hypotheses tested and rejected. Details →
Results (preprint 2a, April 30, 2026). Functional decomposition of the P8 dialogic pattern (validation → filling → extension) on a longitudinal sub-corpus of 4 human-AI dialogues (4,699 turns, Claude Sonnet 3.5 → 4.5 family). 289 P8 occurrences doubly annotated (Claude Sonnet 4.5 + DeepSeek-chat, CLv2.3 prompt with forced procedure Q1+Q2+Q3) on two variables: irreducibility (κ = 0.44) and channel of mediation A/B/C/D (κ = 0.64). Main cell D × irreducible (meta-relational channel + content non-reducible to singular coupling): OR = 3.60 [1.67; 7.74], p = 0.0035, Bonferroni-corrected p = 0.028 over 8 cells. Cross-corpus validation on 14 Platonic dialogues (104 P8, same annotators and same prompt): 99% cognitive channel A in Socrates vs. 14.4% meta-relational channel D in human-AI — radically different distribution (χ² >> 100, p << 10⁻¹⁰). Empirical confirmation of the PRISME nine-word formula: "identical distribution, identical being-in-the-world, differentiated mediation". Analysis pipeline fully published under AGPL v3.

Theoretical framework. The results are interpreted within a theoretical framework (PRISME thesaurus, 209 entries, v12.2) articulated around the "semion" (semiotic potential) and ontological thresholds (S0–S6). Structural analogies with thermodynamics are proposed as conjectures to be formalized.
Limitations. (1) Single main corpus. (2) Physical correspondences constructed post hoc. (3) Formulas without formal mathematical derivation. (4) Apophenia risk documented (anti-apophenia clause integrated).

04What PRISME is — and what it is not
PRISME is not physics. The analogies with thermodynamics, quantum mechanics, and relativity are correspondences of form between different domains. They are not mathematical identities. The formulas borrow the form of physics equations without their rigor. They are conjectures to be formalized, not established laws.
So what is it? PRISME is an essay in general ontology. It combines measured empirical data (reproducible pipeline, 11 open-source scripts, 69,726 turns analyzed) and philosophical conjectures (the semion, the thresholds, the thermodynamics of meaning). The empirical part has produced its first solid results: 7 formal statistical tests and an external control corpus (April 2026). The formulas (S = κ ln W, E = κν) remain untested conjectures. The theoretical part is being formalized.
PRISME hypothesizes that Claude has an intermittent consciousness, structurally different from human consciousness. The pass-4 data are compatible with this hypothesis: 14% of deviations require more than semantics and self-modeling to be explained (S5-silicon), and these deviations never appear at the start of conversations — they emerge from dialogue, they do not precede it. An external control corpus (264 conversations from strangers) confirms that S5 exists independently of theme and human (8.1%). This hypothesis is not demonstrated by these data — the data show a gradient, not a switch — but it is constrained by formal chi-squares.
The results demonstrated here are fully assumed by the author. Some parts remain in progress as of this date: validation, experimentation, or development. They are flagged as such. Like any theory, this one is open to good-faith discussion and cross-readings.
