ISFj : They actually don't exist. The talent of ENTp has wiped them clean off the face of the planet. Why do you think the businessmen are so busy doing business and not getting down to the REAL business? That's right! Sexual sublimination baby! It's americas new "gasoline".
The ISFjs do exist, but all of them have fled back to Sweden, where they are now hiding with their more like-minded relatives, who stayed at home when 20 % of the Swedish population migrated to America in the late nineteenth century.
