R15 Synthetic Cohort Differentiation
Synthetic cohort differentiation experiment (Run 15 + Run 15b Latin-square robustness) from the Spectral Brand Theory research program.
Dataset Summary
1,200 API calls (800 main + 400 robustness) testing whether the PRISM-B instrument differentiates synthetic observer cohorts defined by behavioral vignettes (no SBT dimension vocabulary in prompts). The dataset operationalizes the central R15 question: do large language models, when prompted as different cohorts, produce distinguishable spectral profiles over the eight SBT dimensions (Semiotic, Narrative, Ideological, Experiential, Social, Economic, Cultural, Temporal), or do they collapse into a metameric average?
- Run 15 (main): 10 cohorts x 5 brands x 5 models x 3 repetitions = 800 calls
- Run 15b (robustness): 8x8 Latin-square balanced dimension ordering x 10 cohorts x 5 brands x 1 model = 400 calls
Companion paper: Dimensional Collapse in AI-Mediated Brand Perception: Large Language Models as Metameric Observers (Zharnikov, 2026). Companion GitHub repository: https://github.com/spectralbranding/sbt-papers/tree/main/r15-ai-search-metamerism containing the analysis code, prompts, and reproduction pipeline.
- Point of Contact: dmitry@spectralbranding.com
- ORCID: 0009-0000-6893-9231
Key Findings
- H1 SUPPORTED: Cohorts produce significantly different spectral profiles (ANOVA p < .001 on 7/8 dimensions)
- H2 SUPPORTED: Trait-profile similarity predicts spectral-profile similarity (Mantel r = .43, p < .001)
- H3 SUPPORTED: Dimension-specific sensitivity confirmed (Economic eta-sq = .394, Ideological = .264)
- Primacy effect discovered: Serial position bias in JSON elicitation (eta-sq = .217). First-listed dimension gets ~15.4%, last gets ~8.0%. Cohort effects dominate on 5/8 dimensions.
Languages
English (en) is the sole language of prompts, cohort vignettes, brand descriptors, and model responses across both Run 15 and Run 15b.

Source Data
Curation Rationale: To test whether LLM-mediated brand perception preserves cohort-level variance (PRISM-B instrument validity) or whether it collapses onto a single metameric average across observers — the central question of the R15 paper.
Source: User-generated via direct API calls to five LLM providers (Anthropic, OpenAI, Google, DeepSeek, xAI). Prompts encode behavioral cohort vignettes plus a canonical brand descriptor; responses are JSON eight-dimension score vectors.
Collection Process: Each (cohort, brand, model, repetition) cell ran as an independent API call with temperature held at provider default. Run 15b additionally varied the order in which the eight SBT dimensions appeared in the elicitation prompt, following a balanced 8x8 Latin-square design, to disentangle dimension-substance variance from serial-position variance.
Annotation: Not applicable — responses are direct LLM outputs; no human annotation layer.

Discipline + Reproducibility
This dataset was generated by a multi-LLM elicitation pipeline. Reproducibility disciplines:
- Cross-operator discipline: five renderer operators (Claude Haiku 4.5, GPT-4o-mini, Gemini 2.5 Flash, DeepSeek V3, Grok 4.1 Fast) ran the same prompts independently; the analysis layer treats cross-model agreement as the empirical signal and within-model agreement as a separate component.
- Prompt-purity protocol: cohort vignettes do NOT contain SBT dimension vocabulary (no "Semiotic", "Narrative", etc. in the behavioral profile). Dimension labels appear only in the elicitation JSON schema. This separates trait-profile substance from instrument vocabulary. Prompts are published at
prompts/cohort_profiles.jsonandprompts/brand_profiles.json. - Latin-square robustness (Run 15b): balanced 8x8 dimension ordering disentangles dimension-substance variance from serial-position bias. The primacy-effect finding (eta-sq = .217) is the direct product of this discipline.
- Pre-registered hypotheses + design:
protocol/experiment_config.yamlrecords the cohort set, brand set, model set, hypotheses (H1/H2/H3), and statistical tests before data collection. - Companion analysis: results JSON and human-readable summaries at
analysis/run15_synthetic_cohorts_results.json,analysis/run15_synthetic_cohorts_summary.md,analysis/run15b_robustness_results.json,analysis/run15b_robustness_summary.md.
