Really I doubt that any INTJ male would be able to mistake himself for an INFP. A balanced INTJ might look a bit like a balanced INFP eventually, but he'd be aware of a long and painful road which had led him against his natural inclinations to that point.
I dunno, JivinJeffJones...
The functions are very similar so it wouldn't that much of a stretch..
Maybe BC was mistyped from the start?
Is it that by its indefiniteness it shadows forth the heartless voids and immensities of the universe, and thus stabs us from behind with the thought of annihilation, when beholding the white depths of the milky way?
I vote INFP. Never doubted IxFP. You remind me a lot of my INFP father -- a bit dark for an INFP, not as complacent, and good use of Ni. You also share the same Enneatype that seems to produce a calm personality on the surface, but with nearly palpable energy beneath. His results are N>I>F>P. He is also deeply bothered by emotional outbursts, he say it disturbs his inner peace like heart said. I wonder if other INFPs can relate to that as well.
It also seems the INTJs I know who've been subjected to great stress while younger (all of them, actually), buried their Fi, not developed it. Their Fi is locked in a padlocked chest at the bottom of the Dead Sea.
