For INTJs Ni goes "wow, what a blast" and Te says, "Yeah, and it gets refined like so," and then Fi chimes in with "I concur, and you better do it too, :sob:"
For INFJs, Ni goes "wow", Fe goes, "Yeah, and it gets refined like so", and then Ti chimes in with... what? A categorisation of the Fe result into true's and false's?
But none of it is so simple and discrete. Ni doesn't work on it's own, the judgment function is always there differentiating immediately, and guiding Ni attention, and the third function is always there too sitting in the background guiding too. It's all a mix. It's all a constant processing activity. It's all "thinking." How do you tell the difference between Fe reflection on a topic with a Ti guiding hand, and a Ti focus on categories and details? (Or, hell, you hear about these people with different function orders--maybe, Evan, you're one of those. What's a good way of finding out?)
