Inconsistency within output.
WHERE IT HAPPENS
Long pieces Anything generated in sections Long conversations
THE CAUSE
Each part is generated without full awareness of the others.
WHAT TO DO
"Check this for internal contradictions."
Genuinely useful and rarely done.
FOR LONG DOCUMENTS
Particularly valuable, since contradictions between distant sections are hard to spot.
FOR FIGURES
Check that numbers stated in one place match those elsewhere.
A common and costly error.
FOR TERMINOLOGY
"Check terminology is used consistently and list any variations."
IN A CONVERSATION
If it contradicts something established earlier, the context may have exceeded what it can consider.
Summarise and start fresh.
THE PREVENTION
Outline first, and check the outline for conflicts before writing.
