Your daughters entire thought process of her brain is, indeed, faux science. There is no such thing as a "male/female brain." As far as the physical differences, the small differences do not equal female and male of the whole brain. When size, diversity and ethnicity, bias (read Potential Reporting Bias in Neuroimaging Studies of Sex Differences, for instance) etc. are taken into account, there is no f or m brain.

They found almost no differences that were widely reproduced across studies, even those involving thousands of participants. For example, the volume or thickness of specific regions in the cerebral cortex is often reported to differ between men and women. However, the meta-synthesis shows that the regions identified differ enormously between studies. Male-female brain differences are also poorly replicated between diverse populations, such as Chinese versus American, meaning there is no universal marker that distinguishes men and women's brains across the human species.

Men’s overall brain size is about 11% bigger than women’s, but unlike some songbirds, no specific brain areas are disproportionately larger in men or women. Brain size is proportional to body size, and the brain difference between sexes is actually smaller than other internal organs, such as the heart, lungs and kidneys, which range from 17% to 25% larger in men.

When overall size is properly controlled, no individual brain region varies by more than about 1% between men and women, and even these tiny differences are not found consistently across geographically or ethnically diverse populations.

Other highly touted brain sex differences are also a product of size, not sex. These include the ratio of gray matter to white matter and the ratio of connections between, versus within, the two hemispheres of the brain. Both of these ratios are larger in people with smaller brains, whether male or female.

As for personality differences, there are, again, PARTS where there is small differences that lean more LIKELY to male or female. However, everyones brain, as a whole, is not male/female, in regards to personality, either. Everyone has traits that are male and female. Both. There is no consistency.

In Daphna Joels study, each brain studied had its own unique pattern of “maleness” and “femaleness.” No matter which group of people they looked at, what type of scan was used or which part of the brain was examined, the researchers consistently failed to find patterns that set men and women apart.

So there is no such thing as a female brain or a male brain.

I have actually had pro-trans people on other comment boards tell me that brains have a "gender" (apart from sex) which can be scientifically observed on imaging in fetuses, even before birth. Um -- I DON'T THINK SO! 🙄

Right, all girl fetuses have a little bow on top of their heads and boy fetuses are holding a little train. You can clearly see that on an ultrasound. Didn't you know that?

Yes, obviously. Girl fetuses are so dainty and delicate that you barely know you're pregnant but boy fetuses play basketball in utero. Boy fetuses also do a lot of play-fighting and farting.

😄 Yeah, that is completely insane. Lol The things they believe are beyond irrational.

I get a laugh out of those people. They are SO uneducated and want to sound so smart.
