He does have Ne PoLR because he needs to see (Se) and analyze (Ti) information for himself (introvert) and it must be rational in order for him to finally come to settle on something and the Ne does not shift his focus to abstract ideals just because someone said something interesting. Can't you guys see the actual work that he's put through his mental, rational, process for this, covering details (Se)?
His stubbornness and needing to have information that satisfies his own ideas is a part of being an introvert and having a subjective additive to external ideas.
How do you like my Ti Role in the above analysis? LOLOLOLOL
