you guys should be careful when trying to apply socionics to your mbti type. an INTJ in mbti would score as INTP in socionics thus the relation of duality for an mbti intj would be the esfp with intp in socionics, not INTJ with ESFJ. and mbti intp would score as socionics intj and so I think it's safer to state that the INTP and ESFJ are duals since most people overlook the differences between socionics and mbti, MBTI is the test most people took so I think we should state it as INTP and ESFJ duality so we don't cause confusion.
This explains why the mbti intp is more tolerant of esfj and the mbti intj does not get along with esfj. It's the mbti intj and esfp that are duals in mbti terms, and if you look through this forum and find the consistency of these relations it will make more sense to you.
Also there are different views on type interaction and socionics has it's own method different from others. I prefer Kiersey when it comes to type interaction.
