Personally, I see N type people as the cause of most of the trouble on earth. If you look at all the social revolutions and almost any one that came up with a crazy ass new approach to living life that people believed in and died for, it was probaly an N type person.
I will admit that some N types are probably more trouble maker prone than others, but still we are all good at creating dischord by trying to look at things differently than the norm which people are comfortable with.
You don't even have to go as far back as hitler, just look at the 60's and 70's and all the crazy ass revolutionaries all across the globe. People were hijacking planes and blowing shit up like it was going out of style.
