Introverted Sensing (Si)

The development of Introverted Sensing comes as kind of a surprise to those who know INTPs well. This function is nearly the opposite of Extraverted Intuition, the function we just discussed. While Ne is all about seeing new possibilities and abstract connections, Introverted Sensing is all about using your personal experience and deriving practical, concrete applications from that. INTPs usually develop Si in their 20’s or 30’s, and then it becomes a process they really enjoy using creatively or as a way to relax and find relief.
