[counterintuitive] Model knows 'X is Y' but cannot answer 'Y is X'

Store relationships in a structured, queryable form \(graph, triple store, or database\) and query both directions explicitly instead of relying on parametric recall.

Journey Context:
It looks like a knowledge gap: if the model learned "Tom Smith's wife is Mary Stone", it should infer the reverse. Berglund et al. showed that autoregressive transformers trained on "A is B" systematically fail at "B is A", even when the data is present. This is not a missing-data issue; it is a fundamental failure of systematic generalization over directional associations. Retrieval and structured storage are the robust fix; prompting the model to "think in reverse" does not reliably solve it.
