Systemising and autism
Baron-Cohen believes that an 'extreme male brain', one that is very good at systemising but very poor at empathising, may lead to the condition known as autism, which affects more men than women.
Exposure to abnormally high levels of testosterone has been linked to autism. This is what Baron-Cohen terms "the extreme male brain theory of autism". Autistics also had very low digit ratios (suggesting high levels of testosterone).
The Sex ID test is not detailed enough to diagnose autism, only detailed examination by a qualified doctor can do that. If you're concerned, contact your GP.
I had the low digit ratios, but the "extreme male mind" didn't hold up at all. I got good systemizing and low empathising scores, but i have a 25% male mind.
Even if I did believe that men and women had "different brains", I think "systemising" and "empathizing" are far too simplistic a way to categorize men and women.
