Trust, but Don't Verify: Epistemic Blind Spots in LLM Source Evaluation

A new study reveals that large language models can identify fabricated statistics in isolation but fail to apply this capability when synthesizing multiple sources, instead weighting sources based on analytical presentation style rather than numeric validity. This 'epistemic alignment' failure—where models prioritize how credible something sounds over whether it's actually true—persists across multiple model families and domains, with attempted fixes through prompting producing blanket skepticism rather than selective discernment.

Multi-Agent Conformal Prediction with Personalized Statistical Validity

Researchers propose personalized federated weighted conformal prediction (PFWCP), a framework that enables reliable uncertainty quantification across multiple agents while preserving privacy and handling data heterogeneity. The method provides statistical validity guarantees for individual participants rather than only aggregate averages, with practical applications in distributed machine learning systems.

When prompt perturbations break your A/B test: A valid statistical test for generative surveying

Researchers demonstrate that standard statistical hypothesis tests fail when applied to generative surveying, where LLM-based personas provide market research feedback. The study proposes a valid permutation test that accounts for prompt sensitivity and provides guidance on optimal resource allocation for this emerging research methodology.
