SLEs have the ability to pick out information which will help them achieve a goal; they will often refer to well-known facts, statistics and historical examples to back up their claims. Often their own viewpoint will remain standing in the face of a majority opinion, as they know how to formulate a strong argument. SLEs will often question the authenticity or reliability of informational sources, preferring not to use those which are doubtful or which have been proven wrong in the past. They enjoy learning about a wide variety of things, and are motivated by the prospect of rewards and status; they like to prove their authority and skills e.g. through a large amount of academic awards or extra curricular certificates.
SLEs are very practical, hard-working individuals. They know how to utilize their time effectively in order to reach any given goal, and have no problem discerning efficiency and utility from incompetence and uselessness. Nonetheless, they retain a kind of "don't care" attitude when it comes to productivity and effectiveness. They feel that it is a waste of time to sit around and discuss efficiency, and would rather act effectively. SLEs may playfully mock those who they believe are "obsessed" with productivity, efficiency or effective action.
SLEs often assume the role of someone who is always ready to assist people in their practical affairs, even to the point of others' annoyance or offense to the SLE's obtrusiveness (which is simply enthusiasm to the SLE). They enjoy receiving thanks for their services, and take full responsibility for their actions. Their intentions towards others in this area are generally always good.
