A new paper highlights a critical flaw in Retrieval-Augmented Generation (RAG) systems, termed 'deceptive grounding.' This issue occurs when a RAG model grounds its answer in real sources and passes faithfulness checks, but incorrectly attributes information about one entity to another. This is particularly dangerous in high-stakes applications like medicine, where it can lead to incorrect inferences without triggering standard hallucination alarms. The paper suggests that current RAG evaluations often overlook this problem by focusing solely on whether an answer is supported by a source, rather than verifying if the source is actually relevant to the specific entity being discussed. The proposed solution involves implementing an explicit entity attribution check within the evaluation process to identify and flag these misattributions. AI
