Yeah EIEs seem aloof and contained whereas IEIs don't... IEIs aren't necessarily more outgoing but certainly "warmer" in my observations.The female EIEs are come off as blatantly bitchy or arrogant a lot of the times without much fear of being disliked by those around them... (Think Renee from Americas Next Top Model, cycle 8). Kind of mind boggling when you think is their strongest function?!? It's like they can't mask negative emotions as well as IEIs, and they have blantant comlexes driving their behaviour that they themselves aren't aware of. Maybe accepting Fe IS very different than producing Fe. So in terms of Fe use IEIs are more somehow extroverted maybe?
