Most retarded socionics theorists typically trying to explain Ni as something relating to time. And while Ni does relate to time, this is a gross oversimplification of what Ni does.

In model B the context becomes much more clearer. Both intuitive functions are what I'd call the functions of relativity as they relate to how one views him/herself in relation to the environment, and how one views the environment in relation to the self. Basically the way one tags the meaning of the environment to the self will directly impact the potentiality that one gives the objects in the environment. Both functions basically revolve around how one views the flow of everything.

(-Ni) and (+Ne) functioning typically relates to the type of people are are rather philosophical and introspective. They typically see time and space as this infinite spectrum (+Ne) with unlimited potential. Time, so to speak, runs through their mind. The beta feelers are typically more spontaneous and dreamy. They typically have a romanticeqse personality, as their secondary functioning revolves around localization and roots from common sense derivatives. Alpha thinkers on the other hand, typically have a more long winded approach. Everything is globalized, as they actually attempt to see the root of the infinite spectrum.

(+Ni) and (-Ne) functioning is typically on the opposite end of the spectrum. +Ni is extrospective and adaptive. Typical philosophy is more ingrained in the wave of humanity, thinks of self as loyal to the hive. They tend to see things in a more restrictive, bound to whats in front of their face sense, adapting with the moment. Gamma thinkers typically have a down to earth common sense mind. They make good accountants, statistical mathematicians, stock brokers, etc. In business hierarchies they are usually the man behind the man, as they are extremely loyal. Delta feelers have a very motherly down to earth personality. They attempt to treat everyone as equal, while ironically hold on to their conforming persona. Disagree but accept is the slogan of Delta feelers. They may even go at great lengths to help others conform to their goals through positive reinforcement.
