I think we can all agree that extraversion does NOT equal sociability.

But then why to most descriptions of extraverts state something about high sociability and having a wide circle of friends?

I think this is what scares many people away from concluding themselves to extraversion. People say, "well the ENFp description makes sense, but I like to be alone alot more than around people, so I am obviously not extraverted." Yet everything related to extraversion that is NOT related to sociability makes sense.

Are all ESFps hypersocial beings only focused on fashion and dominance? Why does this not make sense in terms of the non-social, intellectual, clingy INTp as their dual? And the same thing going for ESFjs and INTjs?

Does high sociability necessarily imply extraversion? Does very low sociability necessarily imply introversion? And what about everyone in between?

EDIT: And is extraversion really related to talkativeness?
