If humans were more advanced, we wouldn't be using fairly primitive system such as 'typing' to decipher the internal workings of the mind.
What is the usual criteria for your method? What if said person has a disorder, or a similar variable that would change their behavior outwardly compared to how they really are inside?
Let me guess, you walk up to them and ask what their personality type is afterwards.
It would be nice if you really are that great as there would be less mistyped people on here. Prove it if you are. Go to the 'What's My Type' subforum or something.
I am quite great...but I've already proved that to myself, and anyone who is more than just an acquaintance of me (in real life)
what I meant by "humans are not advanced enough" (which, by the way, if you don't agree with just that statement alone, then you are misled) is:
Typing is absolutely not a primitive system. it's an awesome ahead-of-its-time futuristic way of looking at the world.
the workings of the human mind...are simple, and easily decipherable, if one is determined enough to figure it all out.
about my usual criteria for street-typing strangers; first, I determine their energy + energy level, then I determine their vibe, then I type facially (facial features of similar types I've seen in the past - thousands and thousands in my memory banks), then I watch their reactions more than their actions.
there's a myriad of other hard-to-describe methods that involve my intuition, experience with people, etc.
If I'm single, then yes, I do walk up, and then make new friends, meet girls, etc.
but since I currently am not, I do not usually do that.
however I know I'm 100% accurate, based on my experience typing friends of friends that I don't know, while I'm trying to show that 'friend' how accurate I am.
then after my assessments, we compare those to the actual person's real-life-personality. (the person that I have never met before, but is friends with the friend I am chatting with)
