With a combination of dominant
, the LII is usually a conceptual thinker with clearly delineated views and ideologies. Unless life forces him to earn a living doing physical labor, the LII prefers to apply his analytical thinking skills to non-material aspects of things: planning organizational structures, developing ideas, analyzing data, and reaching conclusions. No matter what he does or where he works, the LII will have a distinct focus on clarifying thought and ways of looking at things.
1. Introverted logic
The LII naturally assesses statements, opinions, and actions in terms of conformance to certain principles. These principles may in practice be rules of thumb based on experience, but LIIs will usually appeal to more general, "self-evident" systems of justification, if the need arises. The LII is often highly critical of others if he believes that they are being intentionally idiotic or making decisions that do not make sense. His dual the ESE appreciates the LII's judgment, but also softens the edge, gently reminding him that how something is said is equally important as what is said.
"Just because" is not in an LII's vocabulary. If there is a reason for something, the LII will probably want to find it. The LII is able to reduce things to their most essential aspects, and recreate the whole from the bottom up. The LII's theoretical tendencies can often leave him out of touch with reality, and if unchecked may lead to "crackpot" theories that are internally consistent but completely nonsensical to others.
The LII may explore many avenues of thought, but in the end only tell others his refined conclusions, as the intermediate steps are seen as irrelevant. He is often too concise for his own good, making it difficult for others to understand his ideas.
