[research] LLM defaults to the most famous entity sharing a name, ignoring context that specifies a less prominent entity

Provide explicit entity disambiguation context or few-shot examples of rare entities in the prompt. If using RAG, ensure the retrieval step uses the full contextual string, not just the entity name.

Journey Context:
LLMs learn strong priors for frequent token co-occurrences. If asked about a lesser-known entity with a famous name, the model's attention mechanism is overwhelmingly pulled toward the famous entity, causing it to hallucinate details about the famous entity. The model lacks an inherent override mechanism for popularity bias without explicit contextual anchoring.
