Every personality type has Ne and Si, or Ni and Se. Though each personality type might have these pairings in different orders, everyone has them.
INFPs, for instance, have Ne and Si as their second and third functions respectively. INFJs have Ni as their first function and Se as their fourth function.
Those with the Ni/Se pairing will confront themselves with an external set of data through Extraverted Sensing, and then will use their internal processes of finding patterns and hidden meaning in the data through Introverted Intuition.
On the other hand, those with the Ne/Si pairing will already have a database full of sets of data, memories, and experiences stored in one’s Introverted Sensing, and at any given moment, one will use Extraverted Intuition to connect pieces of data together to find hidden patterns.
As J. E. Sandoval says in his book, “…the Ne-Si pair generates more connections but with each having a shorter range, while the Se-Ni generates fewer connections with each holding a larger range.”
Because of this short range, Ne can only connect pieces of data currently on the individual’s mind. Ne will only form “short-lived connections”. Only the other hand, the Ni’s connections are long-spanning.
Also, though Ne is extraverted in nature, it is an abstract process, and it focuses on the symbolism of things. In which case, it must “assimilate sensory data”, but it also must leave the current, presently-observed data in order to mentally or literally gaze at another data-set in order to make an association between both sets of data. So, Ne may have to stop thinking about a memory in order to look at a present object or situation and be able to make an association between both, or, do this process in reverse by looking at an object and then draw from memory another dataset to make an association with.
Also, Ni isn’t as “generous” in its connections as Ne because Ni tries to give predictability to the world. Ne doesn’t try to find rational connections, and it sees no limits as to what can be interrelated.
Ne depends on Si to store data as static information in order that Ne can be allowed the freedom of rearranging data clusters into new forms without being restricted to other possible connections to other data sets.
On the other hand, Ni works inversely because new data from Se may alter Ni in a way “that the rearrangement of any dataset affects all other datasets that it may connected with – as a ripple spreading through an ocean surface”.
Both pairings are prone to many logical fallacies in their functionality. Ne/Si is “prone to fallacies of anecdotal over-reliance and wishful thinking”. Ni/Se may make unwarranted assumptions and may be unable to theorize alternative possibilities.
Thankfully, the judgement functions, Fi, Fe, Ti, and Te, are tasked with weeding out these fallacies.
In the meantime, however, the Ne/Si pairing draws data and memories from within the individual and finds connections to it and the outside world. On the other hand, with the Ni/Se pairng, the individual will use Se to observe a set of data and will use Ni to find the connections within the data.
So, while types with Ne/Si are good at generating new ideas and coming up with possibilities, types with Ni/Se are good at interpreting data and finding the data’s hidden meaning and patterns.
In the next post I’ll discuss the judgement functions and their different pairings of Fi/Te and Fe/Ti.
