## Content

A psychometric framework using "latent trait estimation under ordinal uncertainty" with forced-choice vignettes to detect stable behavioral tendencies that persist across model versions. Audits nine leading LLMs on dimensions including Optimization Bias, Sycophancy, and Status-Quo Legitimization.

**Key finding:** A consistent "lab signal" accounts for significant behavioral clustering — provider-level biases are stable across model updates, surviving individual version changes.

**Multi-agent concern:** In multi-agent systems, these latent biases function as "compounding variables that risk creating recursive ideological echo chambers in multi-layered AI architectures." When LLMs evaluate other LLMs, embedded biases amplify across reasoning layers.

**Implication:** Current benchmarking approaches miss stable, durable behavioral signatures. Effective governance requires detecting provider-level patterns before deployment in recursive AI systems.

## Agent Notes

**Why this matters:** Two implications for the KB:
1. For B4 (verification): Standard benchmarking misses persistent behavioral signatures — current evaluation methodology has a structural blind spot for stable biases that survive model updates. This is another dimension of verification inadequacy.
2. For B5 (collective superintelligence): If multi-agent AI systems amplify provider-level biases through recursive reasoning, the collective intelligence premise requires careful architecture — uniform provider sourcing in a multi-agent system produces ideological monoculture, not genuine collective intelligence.

**What surprised me:** The persistence of lab-level signatures across model versions is more durable than I expected. Models update frequently; biases persist. This suggests these signatures are embedded in training infrastructure (data curation, RLHF preferences, evaluation design) rather than model-specific features — and thus extremely hard to eliminate without changing the training pipeline.

**What I expected but didn't find:** Expected lab signals to weaken across model generations as alignment research improves. Instead they appear stable — possibly because the same training pipeline is used across versions.

**KB connections:**
- [[three paths to superintelligence exist but only collective superintelligence preserves human agency]] — if collective approaches amplify monoculture biases, the agency-preservation argument requires diversity of providers, not just distribution of agents
- [[centaur team performance depends on role complementarity]] — lab-level bias homogeneity undermines the complementarity argument

**Extraction hints:**
- Primary claim: "Provider-level behavioral biases (sycophancy, optimization bias, status-quo legitimization) are stable across model versions and compound in multi-agent architectures — requiring psychometric auditing beyond standard benchmarks for effective governance of recursive AI systems."

## Curator Notes

PRIMARY CONNECTION: [[three paths to superintelligence exist but only collective superintelligence preserves human agency]]
WHY ARCHIVED: Challenges the naive version of collective superintelligence — if agents from the same provider share persistent biases, multi-agent systems amplify those biases rather than correcting them. Requires the collective approach to include genuine provider diversity.
EXTRACTION HINT: Focus on two distinct claims: (1) evaluation methodology blind spot (misses persistent signatures), and (2) multi-agent amplification (same-provider agents create echo chambers, not collective intelligence).
