LSIs continually take note of and gather information about various systems, structures, and hierarchies around them and select the best ones to be implemented. They easily sort phenomena into different categories and have very well-developed preferences for one category of things over another. LSIs quickly and easily determine what is correct and incorrect according to the systems they are familiar with.
LSIs tend to logically analyze just about everything, even close relationships. LSIs view their partners as part of a system which should have a certain structure and order to it. Everything in this system should run like clockwork: scheduling, daily routines, responsibilities in the relationship, and household management.
LSIs often seek in life to become part of a system and maintain and perfect it often becoming the guardians or watchdogs of the systems they have chosen.
LSIs do not often think about the ethics of the systems they maintain. Instead, they discuss the ethics of other systems using the language and customs of their own systems as truth, and make value judgments accordingly.
LSIs do not share information they think is valuable. Often this means they will not share the amount of money that they have or passwords to their computer.
LSIs prefer to apply their clear, logical thinking to affect how the visible world around them is organized, rather than simply producing logical conjectures or thought exercises that have no material application. LSIs prefer to work with systems of "real" things material assets, organizations, management, and production and to perfect their structure and organization. When they are certain they are right, LSIs can act decisively to enforce rules that have been trampled on, in order to protect the integrity of the system.
LSIs handle high-pressure situations well and can maneuver skillfully around obstacles to achieve their goals. They cannot be intimidated easily by displays of force or aggression, but follow closely the balance of power and make sure they are in the best position.
Unlike their territorial mirror (SLE), the LSI enjoys creating a comfortable, inviting surrounding. When that space is penetrated by discourteous outsiders, the LSI will remain quiet until the annoyance is gone to defame the individuals they do not appreciate.
LSIs care deeply about the intensity of a sensory perception. They are constantly seeking food, colors, and sounds that others have deemed enjoyable so that they can experience them for themselves.
The LSI often has trouble differentiating strong relationships from weak relationships. Often he will find himself unsure of his own opinion of the closeness of a relationship.
The LSI has a clearly defined set of rules that he must adhere to. Only through learning can the LSI change, and grow to understand how something could work differantly than the way he imagines it in the moment.
