What Gender Is My Brain? The Dangerous Phrenology of “Brain Sex”

History raises cause for concern concerning the stakes associated with relying upon mind imaging to dictate the source of transgender id.

By Alex Verman

When POSE actress Indya Moore tweeted a few “biologically female penis” in February, it created exactly the type of reaction you may anticipate.

The replies to her tweet are gleefully cruel, principally condemning her as utterly irrational and unrealistic. They mirror a standard trope in how the appropriate — and even many liberals, progressive or otherwise — respond to transgender individuals. In their words and minds, our claims we might have the correct to really feel and to behave as our genders, however that doesn’t make it scientifically true; information, so the saying goes, don’t care about our emotions.

I couldn’t help however think about this idea when observing the response to Moore’s tweet. Even those that sought to defend Moore from her detractors did so by invoking so-called scientific evidence of transgender id. One Pink News article shared a quote from the lead writer of a 2018 Sao Paolo Medical Faculty research, which used mind imaging to say that transgender individuals’s brains are specific and identifiable. He steered that the “differences” between transgender and cisgender brains might occur during gestation — lending help to the concept trans individuals are principally “born this way.”

That research from the Sao Paolo Medical Faculty got here out within months of a conference paper introduced by a Dutch and Belgian research workforce. In that paper, researchers used mind imaging scans to check the quantity and exercise of transgender subjects’ brains as compared to cisgender topics. In line with their findings, the brains of transgender ladies seemed and acted like these of cisgender ladies, in comparison with cisgender men.

It’s indisputable that “science” as a way of willpower and inquiry is a moral good. However beyond “science” as the pursuit of information by way of rigorous, replicable, and verifiable means, it additionally operates as a call to authority. Scientific information, and the power to bolster the legitimacy and sway of one’s claims on that basis, isn’t apolitical. Throughout its history, liberal political and authority figures have grounded their claims in an exclusive information of fact and purpose. The dominant mental currents of the Enlightenment and trendy flip in Europe careworn an earned objectivity as the only pure source of information, even before the event of an precise scientific technique. Within the ebook Black on Both Sides: A Racial History of Trans Id, C. Riley Snorton explores how such necessary scientific advances as the development of trendy gynaecology, for example, befell by means of and with repeated experimentation on enslaved Black ladies. For generations, European and American medical researchers within the 19th century used the scientific discourses of comparability and categorization to insist upon intrinsic racial distinction, arguing that one thing about Black individuals made them basically totally different than white individuals on the biological degree. And as disability justice activism warns us, a willingness to cede all authority to those who declare scientific information regularly opens up area for abuse inside methods (reminiscent of psychological establishments) the place those marked for “treatment” or “cure” are robbed of agency over the essential rhythms of their lives.


I talked about this with Zoé Samudzi, a scholar of medical sociology at the University of California, San Francisco. She’s involved that utilizing mind intercourse diagnoses may need the effect of narrowing access to transition-related care by growing limitations to analysis. Provided that we stay in a world dominated by cissexism (as well as other types of oppressive energy), there’s no purpose to trust in cisgender establishments and researchers to create the circumstances for simpler transition.

“Science and objectivity are the subjectivities of power,” stated Samudzi. “The brain sex studies coming out now aren’t unique things to be debated in themselves: they’re a part of an extended body of literature that tries to biologize experiences of sex and gender which are both socially constructed phenomenon.”

As she places it, the thought of “brain sex” may be used by gatekeepers to formulate or additional enforce the script of what a medically acceptable trans narrative that might make someone viable for transition, such because the widespread trope of being “trapped in the wrong body.”

One other drawback with this work is that it takes the very concept of biological sex as something goal in its personal proper — natural, inevitable, and separate from the social development of gender. In line with Anna Swartz, an unbiased researcher and bioethics specialist, this can be a large error. Within the case of mind sex, the very apply of researching, measuring, and figuring out what we understand to be differences between female and male brains presupposes that “male” and “female” are discrete and purely biological categories that exist independently of cultural or social context.

As Swartz puts it, there’s a noticeable hole between the precise evidence this analysis uncovers, and the social claims that they seem to make and legitimize. The undeniable fact that we’ve taken sparse imaging of a pattern in transgender individuals’s brain chemistry as evidence of some type of inherent, biological “trans-ness” says more about how we misunderstand the scientific process than it does about trans id or expertise.

“What has received little to no attention, in both scientific and popular media circles alike, has been the degree to which contemporary fMRI research on transgenderism reflects a particular problematic and misleading research paradigm—one that seeks to understand sex/gender differences through the brain,” stated Swartz by way of e-mail.


She argues that, while this proposition may be intriguing, it’s also not well-founded. This line of considering takes as given that there’s a vital, intrinsic difference between genders that can be situated in the body. The mind is just the newest website of investigation: past research has put emphasis on the endocrine system, chromosomes, or the genitals.

However as biologists continue to encounter variation between people on all of these fronts, the central premise gets increasingly shaky. While it’s undoubtedly attainable to take a look at broad categories and differentiate them on the idea of genitals, secondary intercourse traits, hormones, and chromosomes, we’re nonetheless coping with perfect varieties somewhat than uniform standards. Hormonal modifications happen all through life and sometimes differ based mostly on environmental elements; genital measurement and form and performance is so diversified that it’s onerous to really put the bulk of the world into agency packing containers; and chromosomes are poor indicators of how individuals truly enact their genders out on the planet anyway (to not mention the truth that chromosomal variation is extensively documented). Primarily, whereas it’s definitely true that there exists common sexual varieties, it’s additionally true that these varieties will not be static, consistent, or organic. At greatest, what we name female and male are sets of traits which are as a lot determined by society as they are by biology.

Don’t get me fallacious, I’m not anti-science, and I don’t assume transgender individuals ought to reject science as a approach of dwelling in our identities and our bodies. And once I critique science, I’m not doing it in the identical means that climate change deniers or evangelicals do. Moderately, I’m a scholar of historical past, and historical past raises trigger for concern concerning the stakes related to relying upon brain imaging to dictate the source of transgender id.

These brain sex papers, and others like them, have had a considerably combined reception. Some see them as positives, arguing that their claims are principally good and politically helpful. If our identities as trans individuals could be mapped and noticed early on, then it’d help us push again towards institutional opposition to trans rights. This manner, we have now recourse in the onerous sciences of neurobiology to demand recognition and respect, especially inside the medical system. Somewhat than rejecting transgender id as simple delusion, there’s room for us as an example our wants and circumstances as a organic actuality. It’s a useful response to all those who dismiss our experiences as unscientific and our identities as irrational.

However I fear that this won’t have the meant impact. Actually, I see these brain intercourse research as a harmful extension of an already troubling liberal apply. At greatest, its logical conclusion would only serve to limit entry to transition-related look after already marginalized trans individuals. At worst, it turns again the clock on many years of trans activism, feminist organizing, and anti-racism work, empowering the darkest discourses among the many reactionary right and liberal centre.
