INTJs when asked for knowledge usually ask questions, so they know what answers to give–I was told once this is because they need to make all idea information part of their web and want to know where it’s going to fit in for other people. It startled one of my INTJ friends that I don’t have an idea web. (I have a people web.)
INTPs seem to enjoy the flow of knowledge and information in a much less structured way. Although, an INTP I know once said he has a torture chamber for ideas in his head–seeing how they can be stretched one way or another.
