A Change character, if I'm not wrong, will always see the source of the problem outside of himself. Or at least, his problem isn't what he thinks it is. That's the Symptom/Focus element. He is blind to his actual problem because it is his source of drive / motivation and as such, he doesn't realize that the problem lies in himself and that he needs to change.
The Steadfast character is the same way, expect that even after being exposed to his drive, he'll still decide to focus on where he sees the problem -- because he doesn't believe the problem to be inside himself, rather it's his source of drive and demotivating himself (using the solution) would prevent resolution.
A Change character may be right to change or not, just like the Steadfast character may be right or wrong to not change. It depends on the OS Outcome and Judgment. The Change character sees his justifications being torn apart until he sees the inequity within himself and decides to change his worldview. The Steadfast character may or may not be aware of his inequity / drive but either way, he builds his justifications as better focus on his Symptom rather than his Problem.
