MBTI ISFJ is Si Fe Ti Ne. MBTI usually gives Socionics semi-duals the best likelyhood of success because of the stats on SJ/SP and NT/NF marriage combo successes. So the MBTI INTP (Ti Ne Si Fe) would be their best bet for my overall success.

I dont think either theory structure is bad. I do, however, think some MBTI is useless because of the amout of people that know it. These theory structures can be just as biased as politics sometimes lol. Its kinda sick =p
