INFJ (Advocate) is best read as a more stable long-term center. In a 4-scenario MBTI test, the key question is not only whether you are INFJ, but where INFJ shows up most clearly and where it shifts.
INFJ often makes more sense as a composite core type than as an identical expression in every single area. You may look very INFJ at work, softer in relationships, and more open-ended while learning.
That usually does not mean the result is wrong. It means your INFJ is acting more like the stable outcome of all four areas combined. A single scenario explains how you operate there; the core type explains your more durable center.
