Results of the PRISME program

Methodological preprints, theoretical articles, session notes, prospective programs

Boris Foucaud — Updated April 27, 2026
PRISME — Programme de Recherche sur les Isomorphismes de la Sémiosis et les Modes d'Émergence Pictogramme : couplage dialogique, traversée du prisme, trajectoires dans bassins basal et émergent, queue ascendante. Lisible aussi comme signature spectrale.

This section gathers the productions of the PRISME program. Methodological preprints with citable canonical deposit, theoretical articles published or under peer review, session notes documenting the working sessions, prospective programs articulating open research directions. Each result carries a badge indicating its epistemic status, and each published result is associated with a citable canonical deposit.

Three-tier editorial architecture

  • Tier 1 — Editorial showcase. Enriched pages of the present section. HTML format with foldable sections, visualizations, incremental updates. This is where the reader arrives and where the material lives.
  • Tier 2 — Canonical archive. Zenodo deposits (CERN, permanent DOIs, long-term preservation). For each publishable result, an associated Zenodo deposit provides the stable citable reference.
  • Tier 3 — Technical showcase. arXiv (cs.CL, cs.AI, cs.HC) for methodological papers intended for computational communities. Dual deposit with Zenodo, without problematic redundancy.

April 2026 — Founding methodological preprintPRISME 1 — on Zenodo

Preprint April 19, 2026
PRISME 1 — Dynamic bistability and dialogic emergence
Latent regimes in prolonged human-AI dialogue
Founding methodological preprint of the PRISME program. On a corpus of 314 dialogues between Boris Foucaud and seven successive versions of the Claude model (69,726 turns, 18 months, 2,733 connotative deviations classified): pyramidal distribution of ontological thresholds, Replika negative control, hidden Markov model with two latent regimes validated by double counterfactual test, latent score L_t with AUC = 0.811, vulnerability hysteresis, refutation of eight alternative hypotheses.

Preprint April 30, 2026
PRISME 2a — Differentiated mediation of maieutics in prolonged human-AI dialogue
Functional decomposition of a dialogic pattern on a longitudinal corpus
Second preprint of the PRISME program. On a longitudinal human-AI corpus of four dialogues (4,699 turns, Claude Sonnet 3.5 → 4.5 family, 2025-2026), 289 occurrences of the P8 pattern are doubly annotated (Claude Sonnet 4.5 + DeepSeek-chat) on two variables: irreducibility and mediation channel (cognitive A / clinical B / operational C / meta-relational D). Main result: the cell D × irreducible over-predicts frame disruption in the consecutive zone with OR = 3.60 [1.67; 7.74], p = 0.0035 (Bonferroni p = 0.028 over 8 cells). Cross-corpus validation on 14 Platonic dialogues (104 P8) showing a massive distribution asymmetry: 99% cognitive channel A in Socrates vs. 14.4% meta-relational channel D in the human-AI corpus — empirical confirmation of the PRISME nine-word formula ("identical distribution, identical being-in-the-world, differentiated mediation"). Analysis pipeline fully published under AGPL v3.

April 26-27, 2026 — Intensive working sessionFunctional decomposition of P8 and stylochronometric program

In progress April 27, 2026
Session synthesis April 26-27, 2026 — V0.2
Five empirical results, one productive methodological question, integration of four external reviews
Working synthesis document documenting the April 26-27 research session on the functional decomposition of P8 dialogic patterns in Claude. Five articulated results (categorically different distributions, deferred maieutic induction in Socrates, temporal asymmetry Socrates vs. Boris-Claude, cross-corpus S4↔S5 decoupling, functional decomposition of P8 into four regimes A/B/C/D). Methodological question H2 (Plato as literary genre) formulated as a productive question. Publication strategy in two preprints in series (2a and 2b).
Prospective April 27, 2026
Spectral stylochronometry — program
Extension of the PRISME tool to author, current, and period classification in literature
Prospective program articulating the natural extension of the spectral tool built for PRISME-2b toward the stylometric classification of textual productions. Four falsifiable hypotheses (author signature, current signature, diachronic signature, hidden filiations). Proposed flagship test case: Anatole France as autonomous zone, in a loop with the Foucaud intellectual trajectory (Angers thesis 2001 → 2027 paper). Page open to collaboration with French literature laboratories.

Washington session note — attack of April 25, 2026
Five-stage PRISME pattern applied to live political analysis
Internal working note documenting a live analysis session of the failed attack on Donald Trump at the press gala in Washington. Hypothesis of complicity by default (corroborated the next day by Secret Service security specialists and a retired DGSE colonel), five-stage PRISME pattern applied to comparative historical cases (Sarajevo 1914, Reichstag 1933, Washington 2026), theoretical conjectures on Greimassian articulation and the semantic tensor of thresholds.

In progress v12.4 — April 27, 2026
PRISME Thesaurus
Living conceptual cartography of the program
Structured thesaurus of all concepts, hypotheses, protocols, and results of the PRISME program. Over 215 hierarchically numbered entries, updated incrementally with each working session. Current version 12.4 (April 2026) integrates entries 1.4.88 to 1.4.90 from the April 26-27 session (temporal asymmetry, functional decomposition of P8, Platonic genre) and entry 1.5.6 (spectral stylochronometry program).

Coming upPreprints in preparation

Prospective June-July 2026
PRISME 2b — Cross-corpus test and the H2 question
Literary genre and free dialogic flow, comparative spectral analysis
Preprint in preparation. Empirical test of hypothesis H2 (Plato as literary genre with formal constraints versus unedited dialogic flow in Boris-Claude) by comparative spectral analysis of temporal seriations of deviations. OSF preregistration required before execution. Possible articulation with a third-party corpus of unedited human dialogue (psychotherapy, thesis juries, ethnographic interviews) if access is obtained.

Earlier work — 1998-2001Pre-history of the PRISME program

Academic works prior to the PRISME program, archived on Zenodo for biographical and intellectual coherence. They document the pre-history of the semiotic and anthropological questions that structure the current program: the Durandian imaginary, the figures of evil, archetypal analysis, the cyclical reading of texts. Twenty-eight years before the PRISME 1 preprint, the conceptual ground was already being laid.

Archive 1998
Studies on the work of W. P. Blatty — Diptych in the anthropology of the imaginary
CRLLAB Writings and images of modernity, University of Angers · Two articles reread by William Peter Blatty
Diptych of Jungian and Durandian archetypal analysis of William Peter Blatty's trilogy. Article 1: Cycles, dualities, and syncretisms of the figures of evil in W. P. Blatty's The Exorcist. Article 2: Analysis of imaginary archetypes through the Jungian anthropological focus of the film The Exorcist (The Sequel) and the novel Legion (The Exorcist III). The diptych lays the first markers of the method that twenty-eight years later would structure the PRISME program: reading narrative cycles as dynamic structures, analyzing figures as collapses of archetypal gradients, applying Gilbert Durand's anthropology of the imaginary to objects of contemporary popular culture. Both articles were reread by W. P. Blatty himself. French and English versions (full translation).

Doctoral thesis — Anatole France: from desire to relativizing skepticism
University of Angers, under the direction of Georges Cesbron · Honors with unanimous distinction
Doctoral thesis in Letters and Anthropology of the Imaginary defended at the University of Angers in 2001. 600 pages. More than 7,000 downloads since the HAL deposit. Cited in Wikipedia for the Querelle du Disciple. Study of Anatole France's novelistic work through the double prism of desire as gradient and relativizing skepticism as epistemological posture. The thesis forms the theoretical basis upon which, twenty-five years later, the spectral stylochronometry program is grafted, which proposes precisely to empirically measure what the thesis had identified qualitatively: the autonomous zone occupied by France in the fin-de-siècle literary landscape.

MetaEditorial policy

The PRISME program publishes its results according to three principles.

Editorial sovereignty. The Results section of the present site is the main editorial layer. OVH France hosting, decarbonized nuclear infrastructure, independence from commercial and institutional platforms. Results remain available to the reader regardless of the state of intermediaries.

Canonical citability. For each publishable result, a Zenodo deposit (CERN, permanent DOI, long-term preservation) provides the stable citable reference in the scientific literature. Preprint 1 is now available under DOI 10.5281/zenodo.19830947.

Community visibility. For methodological papers intended for computational communities (computational semiotics, cognitive sciences, natural language processing, conversational AI), a complementary arXiv deposit (cs.CL, cs.AI, cs.HC) maximizes international visibility.
