In my personal experience, sometimes these situations are resolved by switching to another topic or ending the discussion for a bit. Give the INTJ some time to think about it without immediate pressure of a discussion.
Typically INTJs keep pondering for a while why a certain discussion didn't go smoothly and felt unsatisfactory. High chance that they'll come back to you later. For me sometimes I just can't see the angle you're coming from at that moment and I need some space to consider what your viewpoint could have been. Doesn't mean that I'll come to the conclusion that I was wrong, but more that definitely I'll make an effort to get back to a mutual understanding.
