Cognitive functions
Ne doesn't always need people to start working; Ti is one of the most introverted functions.

well it is said that ENTPs with Ti almost as strong as Ne are pretty much introverted

Environmental
We don't like the people around us, So we go inside our heads to play.

one of my symptoms definitely - i do this quite often! its because many people are not my taste! i cant help it so i go play with my mind or i imagine finding myself another group of people. I think strong N doesnt let me hang out with S people - all my friends are N except one who is slightly S (between S and N)! Plus i really do dislike many people!

Emotional state
an ENTP experiencing strong emotions tends to go Ti crazy

this could be true but also it couldnt be true. im not very open with my emotions in a way i dont feel any need to express them but i have no problem talking about them (except i dont know how to say it because i dont understand them exactly and bad ones i just wanna get rid off as soon as possible). But my Ti goes crazy and thous are my introverted moments.

Type dynamics
Being constantly surrounded by SJs can drain an ENTP to the point of introversion. Honestly it feels a little surreal, almost as if everybody is on the same page while you feel disconnected. The "emotional" barrier between ENTPs and sensors is subtle but the difference is night and day compared to the instant connection that occurs when an ENTP meets another NT.

this is true - SJs are not good for me - serious misunderstandings - its like talking to a wall - ISFJ especially
and i recognize NTs - thats also true
but all this could depend on other functions development - its not a rule




anyway - about introversion in general - i really think everybody have introverted moments
plus there are always extreme Es, moderately expressed ones and slightly expressed ones, and 50/50 ones
and E is different in every type - every person displays extroversion in some points and in other points introversion
why and how and in which points i dont know - its a matter of individual...but rationals are maybe in general (if E) - less E then other types

It's interesting I came across this thread, as there was a very similar thread about it in the ENFJ forum about ENFJs tending to be fairly introverted for E-types. My thought on the issue is that being an E only really means that your primary focus is outward, not necessarily that you are out there socializing all the time, or even that you need to go out in the world and make stuff happen continuously. (So, it's more a matter of how you think of the term "extroverted" itself, I believe)

I think it's more that you're interested in how things apply to and work in the outside world, (or, I guess with Ne it's more about possibilities in that sense) but it's not necessarily the case that that interest makes you more directly engaged in it.

"introverted entp" Possibly they are cases of "special snowflake syndrome"

Depression, more likely.
