IEI-Fes have more social desires, but they are very impractical (Te-PoLR).
Both sub-types are highly observant and tend to lose their own viewpoint when analyzing other people. This means that they can empathize with others to a very high degree, even to the point where they “become” the other person.
You seem to have a very good understanding of how I work at least. I don't know how representative this is of all IEIs, but this very strongly resonates with me anyways!
