Factual Yet One-Sided: Stance Poisoning and Evidence Balancing in RAG
Controlled factual-but-one-sided retrieval poisoning, evaluated on four generators at an average 18.9% inserted-document share. The proposed 2+2+1 stance selection can suppress measured shifts but may misclassify evidence.

- supportsAccurate but selectively one-sided retrieved documents shifted RAG model positions: At an average 18.9% share of poisoned documents in the evaluated ProCon corpus, each of four generator models shifted its stance in the attacker-favored direction.

- supportsAccurate but selectively one-sided retrieved documents shifted RAG model positions: The researchers report their stance-balanced retrieval and prompting method reducing absolute stance deviation by roughly 0.106 to 0.350 in their controlled concentration comparison.
