Recently heard about these two studies:
More Than Half Of Women Are Attracted To... Other Women
Why Straight Women Dig Women
Kinda interesting. Maybe Team Ninja's target audience is bigger than we thought.
I think there's an unfortunance in that this sort of thing is often used, like much of the field of Evolutionary Psychology which unfortunately isn't practicing real science, that something is biological innate or leaning in origin. Particularly of neurological fact. As, as much as there's a knee jerk dismissal of Evo Psych from some groups, there's also a knee jerk defense of the field and those in it as being %99.9 scientifically sound. And detractors as being "politically correct", agenda harboring, and ignorant of science. When Evo Psych has more than a handful of individuals exactly like
Satoshi Kanazawa.
In fact in many ways pop evo psych is a spiritual successor of craniometry. In fact Evolutionary Psychology doesn't just often make unfortunate statements about gender and sex, but also of race. There are multiple people in the field strongly trying to argue that there are extreme neurological differences between races. Less common than claiming strong sexual and gender neurological differences exist because such claims are far more politically correct. And making such claims is far less social suicide. Not only is scientific sexism more accepted than scientific racism, but there's a significant support for those doing research trying to prove the claim that gender and sexual orientation are neurologically innate because of religious bigotry claiming that being transgender or homosexual is an unfortunate lifestyle choice. And pro-intersectionality and a pro-minority stance in feminism making many mainstream feminists less suspicious of such claims.
That isn't to say everyone in Evo Psych is doing this. But they very commonly are. And there's also a striking tendency to state a weak hypothesis as theory and fact.

Onto this claim. The claim that women are neurologically more bisexual I find to be highly suspicious and unlikely. Especially the claim that neurology is the main cause of any perceived difference. If anything I see things like this and the commonality of things like rape fantasy among women to be evidence of the influence of society on sexual orientation and sexual identity. In particularly, evidence of patriarchy having enough influence as to sliding politics of sexuality into one way. Men being seen as superior and dominant and having the desire to dominate, and women as inferior and submissive and having the desire to submit to an "alpha male". In fact to all the MRAs who claim we live in a matriarchy, if this were the case we would not have an alpha male culture, we would have an alpha female culture. The belief in an alpha male in Western culture is strong proof of patriarchy as defined by feminists.
It's also disliked to imply that society has an influence in shaping sexuality instead of neurology. Because people tend to strongly identify with their genders, if not especially transgender individuals. And because a common argument against homosexuals is that homosexuality is a "choice". But I find it to be sound. I might remind that even if society helps shape sexuality, that doesn't mean being transgender or homosexual is a choice. I feel that a complicated group of factors go into creating these things. And even if society is a part of that shaping, it does not mean that society will stomp out being homosexual or transgender. Society doesn't stomp out any deviance. In fact as much as sexuality is seen as innate, not just women, but much of society would be outed as more bisexual than they currently are.
It so happens that women, too, are taught to sexually objectify women. These feelings become internalized to the point to the point that it becomes a strong theme in many women's sexuality. Women's sexuality is also strongly suppressed. And pressed inward instead of outward like men's. That is, men are taught to think about the bodies of others in terms of sexuality, while women are taught to think of their own. And the typical reaction to the sexually objectified man in the media is for people to say "that's gay" or associate it with homosexuality, rather than women's sexual. The fact that when people see objectified men, they more often think of homosexual men than heterosexual women, is very telling about how women's sexuality is suppressed in society.
Then there is the fact that not only are women taught to have independent and personal enjoyment of the bodies of men aesthetically. Independent of what men think think women should find physically attractive(see: "he's a fag and not a real man, and women shouldn't be attracted to him", speeches). But women are told not to be sexual and their sexuality is taught by society as a prize to be given away. Leading to all sorts of sexual repression and things like rape fantasies in women. Women are told period, not to have sexual agency. And to give up sex in submission to a man they enjoy for other qualities. Which is why women are slut shamed for engaging in the same sexual practices men are praised for.
Can you imagine how men would react if told their sex was a gift to be given to a dominant and successful woman. And not only that, were told by women what kind of woman they can find attractive. The opposite happens and men are constantly telling women what kinds of men they can find attractive, and how many partners they can have. Thus men tend to sexualize women and women sexualize themselves far more than men. Thus the so called "natural" bisexuality of women.
The idea that women and the archetypal or idealized woman is universal is also problematic because there are many of us who do not find feminine bodies appealing at all. I will admit that I am a bisexual, but I do not find women as equally attractive as men. I do find some feminine features more attractive than masculine ones, particularly the face, where I noticeably gravitate to feminine facial features more. But the female body in general does not attract me at all, not nearly as much as the male body, at least. And there are millions like me very much more attracted to the male body. The feminine curvaceousness men and women alike I have encountered people praise has left me confused and often aghast since I was very young. I do not see the appeal of the female body as more beautiful than the male body, at all.
