Ti as Leading Function (LSI)
The individual views reality through the lens of logic, immediately recognizing the correctness and appropriateness of things and their proper place in reality and in his system of views and behavior. He freely makes logical assertions, often exaggerated, about new information and experience. He holds highest those rules to which exceptions do not exist, and is a habitual critic of people or things that don't follow a set of rules, whether they are those accepted by the community, or his own, or even the other person's. Although he is able to adopt others' rules, his own are always the last word, and these are subject to continual refinement. Often seen as "demanding", due to high standards.
Ti as Demonstrative Function (SLI)
The individual often criticizes others' views from a logical standpoint, picking apart statements and postulates and showing that they are logically flawed. However, he does not choose to do this excessively and does not expect that reality can be accurately expressed in a neat logical systematic anyway.
Si as Leading Function (SLI)
A strong ability to recognize internal physical states in themselves and others, to understand how these states are reached, and to recreate and avoid these physical states. Individuals who possess Si as a base function are drawn to situations that satisfy their inner physical experience. Whenever Si base function individuals are taking part in something that involves recognizing, recreating, or analyzing physical states, they feel a great deal of personal power and enthusiasm.
The avoidance of discomfort is one of the primary motivations of these types. Feelings of internal discomfort can arise from a tense psychological atmosphere, working too hard and sapping the body's resources, being pressured by other people or by numerous "things to do," and from unsatiated or oversatiated physical needs. These types tend to quickly recognize and be quite vocal about discomfort that arises and either take clever measures to dissipate it or simply get out of whatever is bothering them. They are very receptive to other people sharing feelings of discomfort with them and can help alleviate the tension and offer good solutions.
Si leading types are constantly adjusting themselves to their environment (which includes the people around them), and rarely have any fixed ideas about what is "appropriate" to desire in a given situation. Thus they are willing to accommodate other people's needs in an ad hoc manner. It is enough for something to "feel right" for them to justify doing it. This behavior may seem random to outside observers, since it is concomitant with weak Ni.
Si as Ignoring Function (LSI)
The individual is perfectly adept at evaluating his physical state and the quality of his sensations, but gives priority to the external act of experiencing and interacting with the world. He gets impatient with those who stubbornly focus on harmony and equilibrium when there are things to be done in the outside world. According to these types, the exploration of the sensations is something that should be done in private on one's own time, but in public people should be ready to interact, get involved, and command situations without having to weigh out everything first.
Se as Creative Function (LSI)
The individual takes direct action to accomplish his goals and desires in the face of external obstacles, and also the interests of his close friends, family, or associates. This may involve prodding others to take necessary action, deliberately applying pressure in specific situations, or abruptly taking on an organizational role. The individual does not generally seek out confrontation, but he is also not afraid of it. He takes his responsibilities seriously and tends to perform them diligently and with care. He expects the same of others.
Se as Ignoring Function (SLI)
The individual prefers to guide others by providing individual rewards and helping satisfy the needs of specific important people rather than through direct leadership or issuing directives. He avoids confrontation and collisions, but becomes fierce and unbending for brief periods of time if they are inevitable. He does not resonate with the idea of overcoming challenges or beating the competition, but prefers to listen to his internal desires and care for his own physical, emotional, and psychological well-being rather than doing what the outside world seems to demand or require of him.
He is adept at perceiving fights over power of a confrontational nature around him and is very able to resist them or even actively participate in them if that is seen as unavoidable, but he sees no point in giving them priority over a sense of comfort and well-being. Participation in violent physical activities where such fights may take place, as in some sports, are motivated not by those fights themselves but by the stimulating sensations those activities generate.
