I don't think my earlier thread went through.
Color Q is built in large part off of MBTI. However, it is newer, and the results I have seen are shockingly accurate - in the way that I always wished the MBTI was. color q personalities dot com is their website, but if they make you pay for the test, I recommend getting a book that includes it from the library - you don't even have to check the book out, because the Color Q cut out the fat - the test is only 27 questions long! One such book is Career Match, and if you're having trouble finding yourself professionally, I highly recommend it - it's like a more accurate MBTI book built to help you narrow down careers that fit you best and then get the job.
Has anyone else taken this? I have seen six people including myself take it, and we all thought the same thing. "Wow."
Really, it blows MBTI out of the water.
