"LIIs are adept at organizing their understanding into structured thought. They may organize their cogitations into categories, diagrams, formulaic descriptions, or complex step by step explanations. LIIs may have an uncanny knack for understanding, constructing, and deconstructing the abstract and delicate internal workings of abstract systems like computers, natural phenomena, gadgets, abstract concepts, mathematical equations, and anything that captures their interest. They may be extremely precise in their understanding and can tend strive for highly detailed realizations. They can be skilled at synthesizing new information and incorporating into their established categories. They are often attracted to fields like mathematics, physics, chemistry, or other areas of study that deal with highly structured information systems.
LIIs are often highly attuned to the premises of logical consistency and adherence to predefined principles. They may use such unifying principles as a basis off of which to make normative or philosophical judgments and often seek to communicate these ideas to others. LIIs can be difficult for others to understand because they tend to avoid explaining the intermediate steps in their reasoning, seeing only the conclusion as important.
LIIs are, in the colloquial sense, highly rational creatures and may pride themselves on so being. They may live highly structured or regimented lifestyles and can be quite proactive.
Extroverted Intuition (Ne, Ne)
LIIs are greatly in tune with novel connections and the possibilities that exist which they could see their systems and analyses applied towards. They are able to see a myriad of concepts and hence strive to cover different and new fields which have not been touched by their logical analysis. They may avoid harping on one area for too long, instead preferring to expand their theoretical constructs, covering various territory through time; to restrict their logical scope would be to hinder true understanding.
LIIs' primary focus in developing new ideas is to categorize, systematize, and promote understanding about them. They may tend to see novel ideas that have no implications or relevance to a larger ideational framework as disinteresting and pointless. At the same time, LIIs are often minimally interested in real-world application of their ideas, instead preferring abstract and theoretical speculation. They often tend towards contemplative academic fields which allow for abstract speculation to be realized in concrete conclusions.
LIIs typically tolerate unusual lifestyles and they usually tolerate differing viewpoints."
