I have a friend who I'm quite sure, holistically speaking, is an INTP (5w3 or 1). However, he has a very strong Si and relies on it quite a bit. Additionally, I think his Ni is a lot stronger and utilized more often than his Ne. If I gave a rough order, I'd say his functions were somewhere along the lines of:
Ti > Ni > Si > Ne > Te> Se > Fe > Fi
It seems like a lot of people argue that INTP's Ne preference over Ni (according to the theoretical chart) is something of a fatal flaw for them. In theory, I'd agree, but it seems like most INTP's that I know in general tend to have a stronger Ni than Ne, even if they don't rely on it more often. Of course this is highly subjective, but I was wondering if I could get some opinions on the matter.
