I designed this test with an integration of Jung's types, MBTI, and Socionics in mind. If anything it's interesting and I've liked the results so far, coming of course from the maker, but it's really pegged down my family members and friends and the profiles from the result fit them well. The information about the types I used to make this test seems to work better with the intertype relations than my experience with any other stuff I've found online.
My main focus was to show how certain types have part of their thought process in common, such as the INTJ and ENTP, both having intuition then thinking in the traditional sense. I also wanted to prove that intertype relations aren't so fallacious when you get the typings accurate. This is an attempt of mine to moderately "refine" some parts of these three typology systems with a few new approaches. Socionics influenced this of course, but I think since MBTI has just as much influence on it, it can be a pretty good MBTI test. I basically wanted it to be a good MBTI test for having just 14 questions. Some of the questions make you think about how you compare to people you know, and try to force an answer out of you.
