How many of you have heard of the MBTI or Meyers Brigs personality test. It's supposed to be extremely accurate and reflect how you operate and think at a base level. It breaks down the 4 base components of a personality and then creates 16 personality profiles from that. I've personally found my MBTI personality profile(INTJ) to be extremely accurate. Way more-so than anything I've seen with astrology. The online tests are definitely not the most accurate, but I think it'd be fun to see what other people on this forum are.
Here is a link to an online test for it:
