Report #42172

[research] Ignoring provided retrieved context and answering from pre-trained parametric memory

Instruct the model to strictly answer using only the provided context, and append a fallback instruction: 'If the context does not contain the answer, state I don't know based on the provided documents.' Use attention-guiding prompts like 'Based ONLY on the above context...'

Journey Context:
Models have strong priors for popular facts. If retrieval returns a niche or conflicting document, the model's internal weights overpower the context window. Explicit 'only use context' constraints plus 'I don't know' fallbacks force the model to suppress its prior, though this may increase false negatives \(saying IDK when context is slightly ambiguous\).
