A list of the following books prove the difference using brain science: Boys and Girls Learn Differently, by Michael Gurian; Why Gender Matters, by Leonard Sax, and The Female Brain and The Male Brain, by Louann Brizendine. This is such a complex subject, we suggest books rather than blogs or articles for resolution of questions about it.
As you are researching this, you can also immediately click www.michaelgurian.com/Research, where you’ll find more than 1,000 clinical and science-based studies showing male/female brain difference. As Dr. Gurian has noted, “The male and female brain are different because the X and Y chromosomes are different. Thus, patterns of male/female brain difference exist in all cultures, in all races, and on all continents.”
Meanwhile, gender fluidity–the idea that anyone can “feel” like any gender at any time–is a part of the fabric of our contemporary culture and a healthy way of expanding our consciousness about the male and female brain. There is a vast spectrum of female and male brains, with some people who feel and act quite masculine and quite feminine and others who will say, “I think a lot of the time I feel more like her or more like him.” This kind of expanded self-awareness will no doubt continue throughout our human future.
But gender fluidity as a psycho-sociological concept does not change the male/female brain. “Gender fluidity” and “male/female brain” are, thus, different subjects. From a science-based viewpoint, although they both connect with sex and gender, they are, in some ways, apples and oranges.
Male/female brain difference is biological and biochemical–wired into the brain from before birth. Males, for instance, process language on the left side of the brain and females on both sides of the brain. That brain biology–or brain sex— is not malleable or fluid. On the other hand, the way one feels emotionally about one’s own gender at any given moment is a matter of social psychology in the individual.
So, the “apples” are sex (biology) and the “oranges” are gender (emotions). Even transgender males and females fit on the male/female brain spectrum–brain scans show a more masculinized brain in a female body for a transgender male and a more feminized brain in a male body for a transgender female.
Overall, it should be noted that there is no argument among scientists who have significantly studied the human brain for sex/gender about whether male and female brains differ. Drs. Sandra Witelson, Daniel Amen, Louann Brizendine, Larry Cahill, Ruben and Raquel Gur, Richard Haier, and many others in the field have studied hundreds of thousands of brain scans and proven male/female difference. When you hear someone say, “that is all junk science…there’s no difference between male/female brains,” you can be relatively sure these naysayers are not doing actual brain science–i.e. basing their “meta-analysis” on actual lab or field work; rather, they have political or ideological motive that requires them, very specifically, to avoid studying, hands-on, the brains of the females and males they are writing about.
