Even more negative take - insecurity and neuroticism can ofter register as "introversion" if they make someone dislike being around others because it's hard for them to avoid feeling anxious, inadequate, or hostile
I guess that then goes together with the mentioned mental health problems, since this type of personality does not seem to be very...healthy either.
I think lots of people probably confuse "introverted" and "shy." You can get your energy from social interaction while still being very socially awkward ... you just might be pretty miserable, right? Extroverted doesn't necessarily mean charming
lol yeah, one of my friends is like this ^^.
The Myers-Briggs types may be pseudo-scientific, but that doesn't mean that we're not generating all sorts of data, including the interesting observation that more than 75% of all respondents are in the Introspective-Intuitive (IN) quadrant and that a mere 14% of respondents fit into the entire Extrovert hemisphere.
Just had a look at this (since I'm an outlier), and if you look at IN, there are more E in here as there are S even (3 people right now, in contrast to 5 E).
So... while claiming that CFC has a rather diverse population (all different kinds of countries [with a anglo bias], all ethnicities (most likely), large age range), the "personality types" are rather homogenous.
EDIT: This E vs. N is probably strongly related to what is mentioned above, shyness, insecurity, neuroticism, and also with having too much time sitting on your butt, if you read the general description,

EDIT: Not meant to insult anyone, more for introspection
