I took the test. I looked at their explanations of the answers.They didn't match my decision process in many answers. I did mark a few errors upon retrospect. In any event their analysis does not jibe with my own self analysis. One is wrong. I'm inclined the think they are.
I believe men and women are wired differently with female brains having more connections between the two halves. This alone I believe would invalidate any unisex test of right brain vs left brain.
Just my humble opinion. Not a biological scientist just an older than dirt retired mechanical engineer.
