Quote from JutsuIt's important to understand that everyone is both introverted AND extroverted at the same time, by describing someone as an introvert or an extrovert you're simply stating what their dominant trait is. While one persons dominant trait may be extroversion their judgment may be introverted and vise versa. For example, my dominant trait is introversion, yes, however my judgment is definitely extroverted.
Though, as I said earlier in the thread INFJ's are commonly mistaken as extroverts due to their aptitude for communication.

I was taking big 5 theory into account when giving my two cents, because let's be honest, nobody really takes briggs theory too seriously. It's just something that can give you a light grasp on a persons' personality
