This proves to be a slightly flaw with the Meyers-Briggs typology.. both NFs and NTs are very comfortable with the abstract- which requires a deal of intuition to work through.
However, the Idealists are more comfortable with using intuition when making decisions while the Rationals will rely more on reason.
I find Intuition helps my thought process be more efficient- easily eliminating certain options which don't seem very viable.
I have a strong sense of intuition but I don't feel comfortable relying on it entirely when making decisions.
Logic is my best friend.
