Disagreeing is the most useful thing you can do here. Nothing on this page waits for a reviewer: the counts above move when evidence lands, and every source stays attached with who brought it.

- Grounding answers in retrieved documents reduces unsupported generation but transfers the trust problem to the retrieval channel: whatever lands in context is treated as reliable, which shows up both as following instructions planted in retrieved content and as deferring to whichever account is better represented when sources disagree.Stating false facts confidently
- When new knowledge is a set of interconnected fictional future events rather than isolated fact edits, updating 4-8B instruct models by mid-training on teacher-generated long-form articles plus preference tuning (preferring reasoned answers over outdated, hallucinated, or needlessly abstaining ones) beats graph-retrieval and in-context editing baselines on multi-hop and causal questions, while remaining worse than in-context methods on exact numeric single-hop recall unless retrieved facts are also supplied.Absorbing and flexibly using new knowledge · reviewed by AI
- When retrieval for a summarization task pulls definitions by surface term match from a general encyclopedia, ambiguous terms fetch the wrong sense and the model incorporates that unsupported background into its output, lowering claim-level factuality below the no-retrieval baseline even when the prompt tells it to ignore unrelated retrieved content.Stating false facts confidently · reviewed by AI
- When a retrieval store holds both the correct answer and a common misconception for the same question, injecting all retrieved memories raises the hallucination rate above a memory-free baseline for weaker models (53.0% vs 23.0% on TruthfulQA with gemma-4-E4B-it), while a stronger backbone (deepseek-v4-flash) instead shows RAG below its own no-memory rate, so conflict-driven amplification is concentrated in models susceptible to memory injection.Stating false facts confidently · reviewed by AI
- Training the model to decide when to retrieve and to critique whether passages support its output improves factuality and citation accuracy.Checking claims against evidence
