there's more uncertainty involved in the transition from Fi to Te... there's an inner harmonization at work on both a subjective and collective level; Fi is continually recalibrating the 'playing field' according to purely internal categories and impressions; Te functions as a kind of objective barometer, less about matching behaviors to expectations than equalizing and structuring various types of people and behaviors according to a more heuristic model. when denzel says he's going to kill anyone peripherally related to pita's kidnapping in man on fire, you're seeing the most basic and linearized expression of the value judgment Fi makes.
there's more clarity between Ti and Fe, but definitions are less pointed. Ti is the playing field, so all that matters is social context; behaviors are seen more mechanistically and recursively; 'types' of people/groups emerge based on the interchange between the individual and collective; any anomalous behaviors are either suspended or included once sufficient inductions have been made about the given situation's underpinnings. for example an ILE who I would've assumed listened to tool but didn't make the obvious connection until I heard it playing on his phone said that it shouldn't be something surprising or notable.
