Both types can be quite absent minded. I'd imagine INTJs as giving off a more "spacey" aura, similar to the INFJ because of doninant Ni. On the other hand, the INTP has no Se in their top 4 function stack, the INTJ does, however it is repressed.
The question is, Which type is typically more aware of their immediate surroundings, and which one is more "in their head"?
