Ni is a function that serves the process of "transformation". Transformation is to be considered on many levels (logical, ethical, personal etc.) In many instances, situations are hard to escape or avoid and Ni allows a person to focus on a specific version of themselves so as to minimise a problem or enhance understanding of it.
Example #1: Those with a habit of not completing their studies, fall into a mindset where they feel justified in not undertaking the workload and are perhaps concerned with pleasing immediate sensations (partying, lounging around etc.) or have personal problems to deal with.
Once the person has realised the consequences of their laziness, an underlying mindset is discovered as the cause. Whilst every function has a unqiue manner in the solution of a problem, Ni engages the individual with their unconscious thoughts and mindset to focus on a particular trait. "How can I avoid this scenario from happening again?" "What talents of mine can I capitalise on to escape this problem?"
Such problems are derived from habit/behaviour rather than by natural alignments and they can be solved if the individual chooses to focus on another "version" of themselves, which always existed but never was accessed. Further supporting the notion that Ni is a search for new angles or perspectives, requiring a solid insight to gauge action.
The common experiences of individuals having to come to their own realisations to truly grasp a problem or change their attitude, has its foundations in the Introverted Intuition function. External data or resources are not enough to create a solution, it requires a transformed way of thinking from the person's past behaviour.
