Some cool discussions/people here.. Been a lurker for a little while.
I've taken these tests over the years online and off, but I think ISFP sounds about right. I've scored INFP at times too, but I don't completely identify with it (but God bless you INFP's anyhow ). What enlightened me the most was finding that I was E:9w8 . That made more sense. I'm just too confrontational to be one of the more gentle souls (sometimes to a fault)...
I was really conflicted on this issue. How could I be INFP - or ISFP, for that matter - when I had these tendencies? The descriptions that MBTI/etc offer are a bit too passive for me. 9w8 helped me sort it out.
