Trace the recommendation back to its premises and look for unsupported steps.
Give the review a clear task
- Separate observations from assumptions.
- Check calculations and units.
- Look for conclusions stronger than the evidence.
- Ask what fact would change the answer.
Verify a claimed error before revising the original. Another model can introduce a mistake while trying to correct one.
Run the review
Open Pingpong with your question and relevant context. The models review the original question and earlier answers in sequence. Ask for the reasoning behind each proposed change, then verify it before using it.
