hmm maybe we just have different perspectives then. in his article about DCNH subtypes, Gulenko also mentions that a high focus on Ni leads to autistic behaviour, which is common among harmonising subtypes (ignoring reality in favor of mental imaginary). I personally don't have much experience with autistic people (I thought however that I had asperger when was younger), but I've noticed in online forums that many INxx got diagnosed with autism/aspergers, so I think Gulenko makes a valid observation here.
