is it because i lied when i was seventeen?

Yeah, it has been a fixation of mine as well, so I really don't mind rambles on that. It's refreshing, really, because the whole MBTI thing has slowly entered the wider consciousness, but the cognitive functions beyond the four letters are still pretty niche. I've heard they make you put your type in your resume in South Korea; pretty weird, honestly, since I guess it can be helpful but it's not like it's actual science. Although, I've always been more oriented towards the enneagram, if you've heard of it, because it deals with the reason why people are a certain type, what went wrong in their childhoods for them to turn out that way. Kind of like the nurture in contrast to the nature. I am honestly unsure of what my type is in that system still, though!

And thanks for the explanation! I've figured out the terms here now, I think.
