[research] LLM fails to answer Who is B when trained only on A is B

When extracting factual triples from text to build knowledge bases or prompts, ensure you store and expose both the forward \(A->B\) and reverse \(B->A\) relations, as the model cannot inherently infer the reverse.

Journey Context:
Models suffer from the Reversal Curse—a failure of logical deduction across training data ordering. If a model learns 'Tom Cruise's mother is Mary Lee Pfeiffer', it cannot answer 'Who is Mary Lee Pfeiffer's son?'. Agents relying on implicit model knowledge for bidirectional lookups will fail unpredictably on the reverse direction.
