[research] LLM knows 'A is B' but fails to answer 'What is B?' or 'Who is B?'

When building knowledge bases or prompts, do not assume bidirectional knowledge. Explicitly include both directions of a relation \(A->B and B->A\) in the context or fine-tuning data.

Journey Context:
Auto-regressive models are trained on sequences in a specific order. If the training data mostly says 'Tom Cruise's mother is Mary Lee Pfeiffer', the model learns this conditional probability. It does not automatically learn the reverse conditional probability. Agents must account for this directional blindness when formulating queries or providing context.
