Report #16422

[research] Agent fails to answer a factual question when queried in reverse \(e.g., knows 'X wrote Y' but fails 'Y was written by X'\)

Do not assume bidirectional factual knowledge. When verifying facts, query the model in the exact direction the training data likely presented it \(Subject -> Object\), or rely on external search rather than parametric memory for reverse lookups.

Journey Context:
Autoregressive models learn sequences of tokens. If the training data overwhelmingly presents 'X is Y', the model learns P\(Y\|X\). It does not automatically learn P\(X\|Y\). This Reversal Curse means the model's factual knowledge is strictly directional, leading to confident hallucinations when queried in reverse.
