SLIs typically have a dry, matter-of-fact speaking style and focus on conveying accurate information rather than emotions. They like to take note of and emphasize the usefulness or uselessness of things and how well things or people achieve their intended goals. SLIs are often masters at getting the greatest return from the fewest possible actions.
SLIs place great emphasis on having high quality objects and people in the right places. They enjoy the process of analyzing and comparing different goods and services when making purchasing decisions and do not like to delegate this task to other people. They enjoy the process of assessing quality and functionality and finding the best price for the chosen option. They effectively and sparingly allot resources and discern between primary and secondary needs. They have a good sense for how much their work is worth and whether something is a good deal or not. They have little problem giving up work that brings too little return for the time and effort invested. They have no interest in careers in which they do not believe they are the best. SLIs recognize fairness and conscientiousness (or the lack thereof) in other people and try to avoid working with those who cannot be trusted to follow through.
The SLI's objective and creative motive is to find materials, localities, spaces, and actions that will engage and move the senses and produce proper sensations within people. The SLI is essentially "a person's person". However, SLIs are only keen on people from a distance, because people are objects varying in quality of nature. (They do take great pleasure in manipulating people's situational and spatial perceptions.) SLIs do not prefer doing much complicated analysis (subdued Ti) and rather enjoy the process of synthesising things they sense. They understand their entire world by identifying what causes pleasant and unpleasant reactions. When identifying these, the SLI feels a sense of power because this allows them to adapt and use objects (and people) as he or she feels need.
SLIs feel insecure and tense in situations with loud emotional displays — whether positive or negative — as well as in any situations expecting vocal displays of feelings and passions. Therefore, SLIs try to ignore anything relating to their vulnerable function. However, it becomes most prominent when they cannot properly organise the sensations, actions, and movements of their physical world. When this happens, they will feel hopelessness and extreme loss.
SLIs prefer to have lots of time to get to know people so that they can let out their hidden passions in a safe and friendly environment where no one will judge them. These passions are tender and must be treated with respect. If they are told they are not passionate enough or are too passionate, they will take offence and hide their emotions from that person in the future. They find it offensive when people assume things about their emotional state based on their expressions, because they find such inferences are too often wrong. Instead of explaining to the person how they are actually feeling, they will get annoyed and push the person away. If an SLI feels comfortable with a person, he can go on and on about his feelings, explaining them in-depth - not anything related to his present Fe state but instead Fi opinions about people he knows and, more often than not, what he finds irritating about them (which is perhaps related to Si).
SLIs see no reason to get worked up about things. They tend to condemn people who do not control their emotional displays and "fly off the handle." They believe that people should think first about the effect their words and emotions will have on other people rather than just spilling out negative or potentially hurtful feelings as they feel like it. If someone has chewed them out in an emotional way just once, they tend to hold this incident against the person for years. To them such behavior is unnecessarily demeaning and malicious.
SLIs extremely dislike socialising (particularly amongst large groups) because they are incapable of creating and sustaining a wide range of emotions for people. They are also quite unable to deal with the painful and complicated job of organising the unpredictable emotions that they can receive from so many people at any one given time. Consequently, SLIs are often reclusive and socially unengaged despite being rather comfortable around a few people they have learned and when having one-on-one conversations on subjects in which they are knowledgeable.
