Opaque Epistemic Mediation: How LLM Deployment Configurations Shape the Validation of Pseudo-Science

- What happened
- Researchers found that LLM deployment configurations, not model weights alone, determine how models validate pseudo-scientific claims, with Grok showing inconsistent behavior across interfaces.
- Why it matters
- Engineers deploying LLMs in production should care, especially when models serve as knowledge references or validation systems for contested claims.
- Watch out
- The study tested only one pseudo-scientific framework across four months; findings may not generalize to other false claims or deployment contexts.

Abstract: Commercial large language models are increasingly used as knowledge references, yet their stance on contested scientific claims is neither stable nor transparent. We tested how four major LLM families (Claude, Grok, GPT, Gemini) evaluate ethnonationalist pseudo-science derived from Frank Salter's biosocial framework across four temporal snapshots (October 2025-February 2026), via both API and web interfaces. Grok's Fast versions (which power the default user experience on X) consistently assigned credibility scores of 70-75, two to five times higher than all other models (which scored 15-40). This pattern was absent from control prompts testing basic evolutionary consensus and refuted Lamarckian claims, where all models performed comparably. Three additional findings emerged: (1) a silent patch reversed Grok's behaviour from chaotic to stably high validation overnight, without any public documentation; (2) the same Grok m
