It might be hard to look at me from "outside" and say "introvert". The main reason (I think) is my overall confidence in my ideas and decisions. What people may see is someone who is annoyingly "over the top" confident.
I think my confidence is a reflection of the intuitive and judging traits combined. The intuitive trait relates to how I process information. Intuitives use patterns and impressions to evaluate information. It looks like using your gut for understanding. Truly it is more than just trusting your gut. But the processing stage of the understanding is very fast and hard to explain.
When I know something it's frustrating when someone wants an explanation of "how I came to my conclusion". Because I "know" what I know I have little patience for having to convince someone else.
Aside: This is how I react. I don't know how others react. Also, just because I am confident in what I know and get impatient with explaining, does not mean I'm actually always "right". The theoretical me understands the benefit of exploring things with others.*I'm whispering under my breath..."Don't question me. Don't question me. Why would you question me?"*
