These two tests came up on INTPforum a few days ago, and I found them pretty good. They're not your standard MBTI test, but instead they give you characteristics that pertain to the use of a specific cognitive function and it tries to figure out which ones you use most often. There are two tests...

It's cool 'cause you can tell if you rank two functions really closely to each other, which type probably suits you second-best. I lost my results, but the first one had me as an INTP with Fi approx. equal with my Si function (both about 3/5 of Ti and Ne, with Ne a little lower than Ti), and the third one had me as INFP with a Ti/Fi on equal footing, with Ne slightly higher than both.
Pretty cool... cause the INFP description on bestfittype is the definite close 2nd, but the INTP description is almost dead on. All the Ti activities come very naturally, too, but I don't think I started using my Fi until relatively recently (past few years or so).
Anyway, cool tests with a different perspective from normal. Post your results here!
