I can see where Jack is coming from, and I've spoken to other intuitive subtype INTJs who have felt similarly what Jack has described about himself.

I think that 70% on the test seals the lid. This guy is an intuitive subtype INTJ, Ti to the core.

In particular, I can notice similarities between what my writing style used to be and what Jack's is today.

I expect criticism from my critics: it's who they are. I'm not afraid to boast, though, about winning a big conceptual victory for my own side of the friendship line.

(I've noticed he has that intuitive subtype characteristic of social clumsiness, too)
