Despite owning all of her albums and having read her biography/auto-biography 'Piece by Piece', I am still not positive. She's certainly complex. She seems very in touch with who she is, and into self-growth, and is really curious about people (although, definitely eccentric
. I question her being INFP, simply because she seems to have a pretty take-charge, more opinionated attitude about things - and seems pretty solid in where she stands. And, at times she almost comes across as NT, but given her entire life and how she lives it, I definitely think she's an NF.
I almost think she could be ENFx - because in her book she seems to really thrive off of being around people, and getting to know people, and she doesn't seem quiet/reserved AT ALL -- even outside of her performances, in everyday life, she seems to really put herself out there. In addition, it didn't seem like she was terribly shy or wallflower-ish as a child. She questioned authority (for example, The Church - her father was a pastor), and was inquisitive, and started performing in clubs in her teens. If nothing else, I think she's a fairly balanced E/I. I also think INFJ isn't out of the question. [And, oddly enough, I can see why substitute thinks she's a T - but again, given her life as a whole, I go NF]. I guess I see INFP as my last choice of the NF's.
The book is SO interesting.
Obviously it can leave more question marks on her type, though....
