How do I find contradictions in my worldbuilding rules?

A four-step working method

1. Write one rule and its cost, constraint and exception in plain language.
2. Trace who benefits, who pays and which institutions enforce it.
3. Test the rule in an everyday scene and a crisis scene.
4. Log contradictions as revision questions, not additional unexplained lore.

Common errors to avoid

• Presenting a new interpretation as established franchise canon.
• Treating an empty worksheet field as a confirmed zero or a verified fact. Mark missing information explicitly.
• Sharing a working brief as a professional conclusion. Keep assumptions and unanswered questions attached.
