how to spot the difference, visually:
INTPs have a more unkempt appearance.
INTJs typically look quite neat by comparison.
I completely agree.
My fiance is an INTJ. He is never unkempt. Laces are done a certain way. He is always prepared and buttoned up, for any meeting. He oversees people, gets stuff done,
or more precisely, he gets people to get stuff done, is sort of the shepherd dog. He needs to be occupied, though he can be very lazy during his 'off' times. If he doesn't have a project, he is fine at first, then goes nuts. Very neat and very particular with his space, very focused when working.
My INTJ has a great knack at hanging pictures up. Months later, he will re-organize the pictures and declare the new version 'better'.
My boss is an INTP. He looks like an absent-minded professor, with hair going one way or another. A kindly man BUT can be very exacting and has a memory like a bear trap. If employees show emotion or there is an emotional issue in the office, he is flummoxed. He can seem incredibly indecisive, but I think it's more like his working toward a theoretical ideal. Can sometimes seem like he's in another world. Is very likeable to clients.
My INTJ is very likeable, too, and comes across as an extrovert. The difference is definitely the J. Both are fast drivers; the INTP is more reckless. The difference is, the INTJ swears at everyone else on the road.
