Although I have some difficulty understanding the cognitive functions, I think I have come to a theory about the role of introverted thinking in ENTP's. While the outside world is all about possibilities for the entp because of Ne, they need to have inner control because of Ti. As someone who might be an ENTP, this causes me to set many rules in my house and have everything in its specific place. By having my inner self(home) structured, I am free to be creative in my outer persona like when I leave my house. How does your Ti influence how you act?
