Ni as a suggestive (5th) function - ENFP and ENTP
The individual is attracted to people who are confident in their ability to evaluate where present trends are leading and to choose the opportune moment to initiate action, or to refrain from it. The individual is impulsive but at the same time desiring of not going too far in his impulsiveness and unsure of his own ability in this area, so people who are confident on how far to go and when to stop are admired and their company is desired. The individual also longs for a sense of greater meaning in his life beyond the immediately physical and enjoys the company of people who can show him the light in that area.
Ni as a base (1st) function - INTJ - INFJ
As a base function, Introverted Intuition generally manifests itself through a lack of direct attention to the world around oneself, and a sense of detachment or freedom from worldly affairs. This can lead to a highly developed imagination and very unique mental world, but it can also result in a great deal of laziness and apparent inactivity. Because the individual gets his/her primary information about the world through imagination, a person with base Introverted Intuition may be able to thrive in situations where data are scarce, or where he/she lacks the usual prerequisite experience. However, this may also become a disadvantage if the person ignores real data about the world too much. The ability to transcend the axis of time and understand the cause and effect relationships that occur is also a feature, sometimes resulting in the ability to accurately predict general future trends and outcomes of certain events.
as a creative (2nd) function
The individual likes to predict the further development of the situations and topics that he is interested in. The individual applies his highly developed sense of vision not as an end in itself, but as a way of promoting the development of his more central interests and activities.
as a role (3rd) function
The individual is able to turn his attention to longer-term implications and personal imagination but only for brief periods; his natural preference is to concentrate on the immediate surroundings and sensations, or on the job at hand. If poorly developed, this function can lead him to extensively plan his future while failing to evaluate his reasons for doing so.
The individual prefers to focus on immediate tasks, taking things as they come, rather than try to evaluate the outcome of present trends. Inclination to tell stories or narrate events on a sequential basis, rather than outlining how one event led to another.
He perceives time in an undifferentiated manner: the past, present, and future are all perceived as being in or near the present. When talking about the future (especially one's longer-term plans), the individual treats it as if it were accessible today and often is not aware of all the developments that must happen first.
He generally has a poor sense of how long things will take and what the best amount of time to spend on things is. Therefore it is difficult for him to stay on schedule without extensive (even total) pre-planning.
