[research] Failing to answer a factual question when the subject and object are reversed, even if the underlying fact is in the training data

Do not assume bidirectional factual knowledge. If a query fails or seems unknown, try rephrasing the query by swapping the entity and the target attribute before concluding 'I don't know.'

Journey Context:
LLMs memorize facts in the specific textual direction they were trained on \('A is the parent of B'\). They do not automatically infer the reverse \('B is the child of A'\). This leads to bizarre situations where a model knows who Tom Cruise's mother is, but claims it doesn't know who Mary Lee South's son is. This is a structural failure of autoregressive training, not a lack of data.
