Can ENTPs mistype themselves as INTP because of shyness/withdrawn with strangers or not-well-known people, but really talkative with close people?
And can ENTPs stay alone a lot of time enjoing their many interests in solitude?
Key words:
shyness/withdrawn with strangers
talkative with close people
Extroverts are stimulated by the outside world, and new interactions with people are invigorating. Yes, you can be a shy extrovert. But this would mean that you would have an unquenchable "itch" to go out and interact with people, and yet that "itch" would be a source of anxiety/fear since satisfying your urge to communicate would entail problems causing your shyness (whether it may be social anxiety, stuttering, feeling like an outcast in a conversation, etc...).
Being a shy extrovert is like a caged eagle. You were meant to fly, but there is steel trapwork around the perimeter preventing you from doing so. This can lead to major disorders such as depression, more anxiety, and fatigue.
Your mention of being comfortable with communication in a familiar "close friend" type of setting leads me to believe you are on the introverted scale. Less is more for an introvert. More people is never enough for an extrovert.
ENTPs are probably one of the most extroverted types. If a magic genie purges away all of the specific issues causing your shyness, could you picture yourself being out there and genuinely enjoying yourself with a crowd? Or vice versa?
There is always some sort of "noise" in one's persona that could distort an accurate typological assessment, whether it may be logistical (you were born and reside in some weird farmtown in Oklahoma with no people around to meet), medical (head trauma causing mental disorders), or psychological (social phobia). Removing the noise reveals the true you.
Do you enjoy your interests in solitude because its the
next best thing after going out? Or do you just enjoy the serenity of solitude because it feels natural?
I guess the real question is: Why are you shy? ... Lack of confidence? Lack of people skills? Fear of the unknown? Fear of rejection? Lack of a sense of humor (too dry, stern, and generic sounding)?
Again, think of the eagle scenario. Do you have a
natural urge to interact with the outer world, yet refrain due to the foregoing traits (or lack thereof)? Or do you feel 100% at peace with your activities in solitude, yet feel as if there is some kind of "void" in a facet of your life (sociability)?
