LSE is one of the 16 Socionics types, known as The Director or ESTj in MBTI cousin notation. LSE belongs to the Delta quadra and is characterised by leading Extraverted Logic (Te) and creative Introverted Sensing (Si). The Dual of LSE is EII (The Humanist).

Description
Rapid, clear, sober mind. The LSE knows how to act intelligently and logically. Their bearing is sporty, their facial features sharp — and beneath it all, a covert nervousness and high internal emotionality. Their motto: force, integrity, and a sense of duty. They are a born scout: collecting information through every available channel until they have an absolutely clear picture that gives them the certainty to act.
"All I do is done well." Initiative is habitual to the LSE. They are decisive and like to be at the centre of things. They defend their ideas with guts and fervour and are not shy in front of superiors — if anything, they become more assertive. They know that a task only goes perfectly if the right tempo is set from the very beginning. They do not tolerate procrastination and are ardent fighters for quality and thoroughness. Like Thomas Edison, a representative of this type is capable of working almost twenty hours a day.
"Rage is a mighty god of the strong." The LSE tends to shake others out of complacency. They do not speak much about what is good — they consider it self-evident. With their grumbling manner they try to cut through others' excess emotion, believing that redundant feeling tires people. During a conversation they may pressure or even attempt to intimidate their interlocutor; but if people do not fear them, they become courteous and polite. Fury is their line of defence in emergencies where they otherwise feel helpless — its purpose is to mobilise their partner, and once that is achieved, they calm down.
Belief in playing fair. The LSE considers obedience to rules a mark of strength. They do not tolerate slyness or deviousness, and hate cheats. They believe that political manoeuvres may produce quick effects, but truly lasting results come only through hard work. They like order. Having bought something new, they will read the manual before switching it on. Roald Amundsen, a representative of this type, managed to avoid extreme situations all his life — "Victory awaits those who keep things orderly," he said. "This is what we call good fortune."
"A reserved force characteristic of military officers." The LSE looks well-built and carries a straight bearing even if they have never served in the military. They dress well and elegantly but dislike dressing demonstratively. They wear their clothes for a long time — it always looks fresh, as if unaffected by time. They never buy uncomfortable shoes. An aesthete who also insists that others dress neatly.
