[research] Failing to answer 'Who is X's parent?' when trained only on 'Y is X's parent' \(asymmetric factual recall\)

When querying for bi-directional relationships \(e.g., variable assignments, class hierarchies\), do not assume the model knows the reverse relationship. Explicitly search or retrieve both directions, or structure the knowledge graph/RAG to handle inverse queries.

Journey Context:
LLMs struggle to generalize factual relationships in reverse. If a codebase defines A extends B, asking 'What extends B?' might fail if the model only memorized the forward declaration. This is a fundamental failure of autoregressive training. RAG must account for this by indexing bidirectionally.

environment: Codebase analysis, knowledge retrieval · tags: reversal-curse factual-recall autoregressive · source: swarm · provenance: The Reversal Curse: LLMs trained on 'A is B' fail to learn 'B is A' \(Berglund et al., 2023\)
