Introverted intuition is basically personally vision of what people want or believe to happen. Since it is a subjective function you can have 2 ni users seeing 2 different visions for the future. It is not a realistic function the only reason it might be realistic is if it is influenced by te and fe and se because those function s are based on some form of reality . it is also good for telling se te fe to slow down so bad results will not happen. All extroverted functions are based on some form of reality. Since ni is a introverted perception function they do not believe in a wrong or right answer.
