About a month ago, I took this personality test. Yes, I was testing to see if I had one, because we all know how suspect that is! 
Seriously though, I took this test, or one similar, about 15 years ago also. I don’t quite recall what I scored way back then, but I don’t think it was exactly the same as I score now. Very close, but not quite the same. I’m not the same person I was 15 years ago either. I suspect people would get different results if they took the test at different times during the same day. Moods change, perceptions change – heck, missing lunch or not getting enough sleep could alter your results on any given day! Here’s the link if you want to take the test too.

MY Results: The MASTERmind! Mwuhahahahahaha! and ISTJ
I took these about a month apart. Actually, I retook the test because after I took it the first time, I forgot that I’d taken a snapshot of my results. I thought I had emailed myself the results so I spent 20 minutes looking through my email folders. Yeah, not a very “mastermindful” moment. Sigh. Anyway, here’s my results. 
What type are you?
