But I don't think that your point of "Tumblr" or even "MBTI-Tumblr" specific populations has any relevancy to the question being asked.
First point...
Assuming that there are diverse types of people that actively use Tumblr, this "Tumblr population" you speak of is a good representation of the (not restricting to) national population as a whole. (I'm pretty sure though, that Introverts tend to use Tumblr, or just the Internet, in general more however. Idk, might be wrong. Just my observation.)
Moving on to the next point... People who took the MBTI, or as you call it, the "MBTI-Tumblr" specific population would STILL comprise of equal numbers of Sensing AND Intuitive. I'm sure equal numbers of Sensing and Intuitive preferring people have taken the test.
The difference is that Intuitive people are overrepresented in the "MBTI-Tumblr" specific population.
^ I don't think you understood that.
My question is didn't ask for background information, which you gave me plenty of, thank you very much.
My question is specifically asking WHY Intuitive people are so OVERREPRESENTED, of which explanation you didn't provide me at all, no thank you.
Thank you for attempting.
Last point...
Funny. I think it's possible to be mistyped. I have friends who say they are P but are actually J. More often, I have friends who strut their Ni around, when really, they are Se. More than being mistyped, I think mistakes happen because of lack of information.
