Debugging a wrong answer: retrieval or generation?

When an AI-supported output is wrong, the first diagnostic question is whether the system saw the right evidence at all, before asking whether it reasoned about that evidence correctly.

A wrong answer built on the wrong or incomplete source evidence is a retrieval failure; the model may have reasoned perfectly over bad input. A wrong answer built on the correct evidence is a generation failure, and a different kind of fix.

Conflating the two wastes investigation effort: teams sometimes retrain or reconfigure a model to fix what was actually a missing-document problem.

PUT THIS INTO PRACTICE

  1. 01Check what evidence was actually retrieved before reviewing the answer.
  2. 02Separate a retrieval fix from a generation fix in the incident record.
  3. 03Test retrieval quality independently of end-to-end answer quality.
