humanmetrics is an axis test that is in the same format as the Myers Briggs. It attempts to isolate preferences by using binary responses. Unfortunately, this creates a lot of "man that could really go either way depending on..." conundrums, but that's intentional to develop contrast in the preferences.
Try taking the
keys2cognition test if you haven't already, then compare the areas where they correlate. Most people seem to get a pretty fair degree of correlation.... ~75% or so. That should help you get more in the ballpark if you're still curious. Some people also like the
Mental Muscle test, which is in yet another format.
Edit: And I just noticed that you replied to my blog pretty much along this subject. My bad.
