I am just wondering which type is the best at typing people?

My assumption is that intuition is the best tool for typing people.
I'm interested how do you go about typing people. How sensors do it? You go to a person and ask him questions?
Describe your method for typing, and mention what is your base function.


edit: I just realized "typer" might not be the right word. Is it typist? ... can't change topic name now
