INTP. (INP "Behind the Scenes" aka Supine in Inclusion/Affection + NT "Rational/Theorist" aka Choleric in Control).
Went through life with the typical Aspie obsessions, one after the other but knowing nothing about personality theory (except my father giving me a little lecture about introversion and extroversion once, and another time, "thinking" and "feeling", though in a more generic sense, like it may be logical to do something destructive to achieve something, but then the "heart" will temper that decision), and he was always complaining about things "abstract" as opposed to "concrete reality"). Yet when my wife eight years ago decided to use the temperament system of a counseling ministry to increase her psychological credentials, and tested me and several family and friends, I became obsessed with temperament. (Due to the
symmetry of the 2D matrix: introversion/extroversion and people/task, yielding the four, and in one system, five temperaments. This appeals to the dominant introverted Thinking). Then, a friend introduced us to the Keirsey Sorter II online, and I then become determined to find out how the two systems fit together.
I then over the course of the years developed several pages introducing the theories, plus how I believe they fit together (with evidence gathered from type discussions).
Shortest versions of the introduction to both theories:

Taken many quizzes online, and generally come out with a high (most definite) N over S preference, then usually P over J, I over E, and then T edging out F. This last one I believe may involve AS, as the syndrome's poorer regulation of sensory input (including
emotions) makes us not only more aware of our emotions than the average dominant Thinker; but also generally puts us in situations where the ego feels threatened a lot, which also triggers inferior Feeling (both extraverted and introverted depending on the situation).
