Cross-domain consistency is not trying to prove that you are inconsistent. It measures how much your personality expression changes with role, goal, and relationship. It is especially useful when your core type is something like INTJ but none of your four areas is exactly INTJ.
It compares the four-letter results you get in daily life, relationships, work, and learning. If all four areas are the same, consistency is high. If they shift a lot, consistency drops.
Your core type is not chosen by picking one area. It is calculated by combining the four preference axes across all four areas. Scenario types show how you run in one setting; the core type shows your more stable long-term center.
