This is what Ej temperament looks like:

Notice how engaging Tyra is, how her emotionality flows along with her words and it seems to be connected with her environment, with the interviewer. She is kind of the person who could make you smile by just smiling herself. Like her entire body is putting in the effort when communicating. Her energy when speaking is fairly high, fairly active, she talks fast and knows what to say and which gestures to make intuitively without much effort. This is because of Fe as the dominant function.
Now compare that to Nicki:

The manner of speaking is slower, less energetic, more detached. She looks inside herself when deliberating, thinking what to say next and remains inside herself, running over her thoughts. Her voice is monotonous, which indicates a more distant disposition, in stark contrast with Tyra. Her processing time is slower, even though the final product she presents is framed in terms of Fe. Although her movements are fluid, she doesn't move much, doesn't invest herself physically (I > E).
I'm describing what I see because it seems often what's obvious for me is not obvious for other people.
I don't know what you're seeing Starfall. EIE or any manner of extrovert is a ridiculous typing.
