INFJ or ISFJ? I guess it's a matter of perspective. Literally. Sounds like she focuses her thoughts on landscape/holistic concerns, versus matters of practical detail. While this is an easy way to topically differentiate, it isn't always reliable. ISFJs can often be panoramic in their approach to what they find personally important, be it a critical social issue or a family cause. Problem is, same can honestly be said for INFJs.
So, besides the stereotpical jazz, it's probably prudent to look at what you want versus what you observe.
Would you prefer ISFJ or INFJ?
