i'm a 7w6 enfp . . . but often 7's mistype themselves as 4's & when i was younger i'm sure i often would have thought of myself as a 4 . . . the description for 4's are so much more artistic, passionate, dramatic, intense = glamorous in a way & 7s just seem like superficial schizophrenics hopping around all over the place unfocused. yuck, what enfp wants to be that . . . but i am definately a 7 i am.
as far as differences amongst enfps . . . i have gotten 3-5 enfp female friends into this stuff & they all feel like they are 7w6 also as well as being SX first as opposed to SO/SP . . . of course i don't know how well the average enfp knows herself. conundrum.
