I found my way here after doing an online MBTI test and immediately assumed that INTJ = LII. When I realized conversion wasn't that simple, I tried out the EII glove but couldn't make it fit. Then somebody typed me SEI and because I was foolish enough to believe there was consensus here on the basic theory (haha) and because I thought that I was missing something (it seemed so complicated) I went through each type again in a process of elimination and landed up back at LII.
