Set a Grounding Contract to Control Hallucination
Identify 3 distinct mechanisms behind hallucination even with RAG, and define a grounding contract that mandates citation, a clear fallback, and a source-priority rule for conflicts.
Distinguish 3 different hallucination mechanisms that persist even with RAG
Define a grounding contract covering citation, fallback, and source priority
Recognize the most dangerous hallucination pattern: confident and plausible-sounding
Set a Grounding Contract to Control Hallucination
RAG exists precisely for this reason: to give the AI "grounding" — forcing it to answer based on retrieved chunks instead of making things up from its internal training knowledge, which can be wrong or outdated. But there's a common misconception to break right away: RAG reduces hallucination, it does not eliminate it.
