Is there a correlation between MBTI types and always needing more solid information?
Off the top of my head I would say the most obvious ones are S types in general because nearly all of the information I have read points towards sensing types always asking for more information to confirm that they are correct in what they know or understand.
This is especially noteworthy in areas of education.
However I find that with this theory most people will be asking for more information since there is no solid ground to stand on besides group agreement on what a type constitutes. From this angle any type could be a seeker of more information in a situation of little confirmation.
Despite this S appears to be the fact-checker of the situation whereas N is the certain-speculator. I'm generalising of course and I could go into more detail with the functions but I didn't want to wall of text people too much.
Besides that could make up an interesting discussion later on.
