Observational studies have shown that the male brain is hardwired to be paid more, occupy more powerful roles and positions, and be more inclined to kill things randomly, whereas the female brain is hardwired to get more harassment and oppression, develop worrying obsessions with physical appearance and to care more about other humans and sometimes kittens.

I find this report very interesting!! I would love to see if there was a study on how environment effects how our brains work? I am a woman physicist, so already don’t fit into the traditional stereotypes associated with the differences between the male and female brains, so would be intrigued to see a study on how much this genetic difference in our brains weight out the differences due to environment. 🙂
