My so-called character is perceived differently by children than by my peers, differently by animals than by people, differently by older people than myself, etc. For some I am inexperienced and naive in some areas, for others I am competent and self-confident.

Well stated.

Perhaps try taking the quiz while imagining yourself at a new job, then take the test imagining yourself surrounded by your closest friends. And compare the results.

I find that often, when I'm with friends, I turn into an ENTP.
