When the E<>I spectrum was subjected to more rigorous analysis it turned out it may just be a metric of "talkativeness" and not really related to the Jungian concept.
Agreed the term "extroverted introvert" is not most clear. What I tried to express in this post is "even though social interactions can be draining to me, I'm comfortable being outspoken and actively participating in discussions, which gives me an advantage in the work setting," so most similar to (2) in your description above.
Thanks, just realized that is me. I prefer to be alone most of the time, but am able to enjoy the occasional party, and even give a speech/talk when needed without issue.
In the old days we had a word for people who neither sought nor avoided emotional stimuli: normal.
Aside: Please forgive the nitpick, but despite its widespread use I really don't think "extroverted introvert" is a thing. The problem is that these two things are opposite ends of a spectrum. I think what people really mean when they say "extroverted introvert" is one of two things:
1) Ambivert : "a person whose personality has a balance of extrovert and introvert features"
2) Introvert, but not shy : It is a common misconception that introverts are inherently shy. The two are correlated, but not the same thing. You can be introverted and not be shy, either inherently or by learning to overcome shyness. Extra/introversion has more to do with your preferences and where you derive energy from. Shyness is more fear-based, and fear can be overcome.
Anyway that's not really a critical part of your article but I've sort of unintentionally become a Myers-Briggs nerd over the years and enjoy discussing stuff like that :)
