Since both use introverted thinking, both are extremely analytical and love to ask questions – because their motivation is not using information, but understanding it. However, the INTP is more analytical than their extroverted counterpart, because that is the function they use most. Rather than coming up with endless possibilities, the INTP filters all new information and ideas through their logic to see whether or not the idea is logical before they “waste time” thinking about it further. The INTP is going to be less verbal with their ideas, since they want to fully think them through first (but more vocal in asking questions, so as to get more information). The INTP is also going to be more self-analytical – since they are so analytical, and live so much inside their head, naturally they are going to want to understand themselves.
