When Truth Is Distributed: Misinformation Derails Collective Fact Recovery in LLM-Based Multi-Agent Systems

ForesightSafety-TIDE, a controlled evaluation framework that strictly pairs all-honest collaboration with controlled deception by a key evidence holder and analyzes the aggregation process through multi-stage voting, testimony adoption, and evidence-root lineage propagation, reveals both the fragility of distributed fa...

DiverValue-Bench: A Benchmark and Fine-Tuning Framework for Aligning Large Language Models with Diverse Human Values

DiverValue-Bench is introduced, a population-aware benchmark for evaluating multi-dimensional value alignment across 74 countries/regions and it is shown that lightweight preference-based fine-tuning with Low-Rank Adaptation and Direct Preference Optimization substantially improves in-domain value alignment while yield...
