Alessandro Strumia, needs to have had a five minute talk
with the late great Ben Barres. Dr Barres was fond of telling a story where he
heard how much his work was “better than your sister’s”. Ben was a female to
male transguy. For those unfamiliar with the lingo started out a woman … then
transitioned to living as a man. This is a clumsy and non-PC way to put it I
know… but when preaching to people one must speak their language. Transgender
scientist can tell you all about how different gender-based stereotypes and
assumptions affect us. More importantly, the latest science comparing
transgender brains to cisgender brains can illuminate the basic premise of
talks like the one given by Alessandro Strumia. Are male and female brains different in
a way that is relevant to the ability to be a scientist? Lets take a
look at the information. MRI and FMRI studies can tell us how different male and female brains are in vivo and the one type of research that does this looks for evidence of transgender brain differences.
Transgender Brains Illuminate Sex Difference AND Sex Sameness
The short version of the rest of this section is that studies
of transgender Male To Female and Female to male illuminate the fact that XY biological
males and XX biological females have both between group differences and a great
deal of overlap. Here is a brief sampling of the research and results from
just this year or so alone.
These are quotes from a few different studies.
“Sex differences in FC between the cisgender adolescent
groups were observed in the right supplementary motor area within one of the
two SMNs (SMN-II; girls>boys) and the right posterior cingulate gyrus within
the posterior DMN (boys>girls).” 1.
“We found lower global brain volumes and regional GMVs
in a large portion of the posterior-superior frontal cortex in the cisgender
women group than in the TTW and cisgender men groups. Additionally, both
transgender groups exhibited lower bilateral insular GMVs than the cisgender
women group. Our results highlight differences in the insula in both
transgender groups; such differences may be characteristic of TW. Furthermore,
these alterations in the insula could be related to the neural network of body
perception and reflect the distress that accompanies gender dysphoria.” 2.
The observed differences in things like grey matter to white
matter thickness in various regions would relate directly to reproductive and
social behavior. Not spatial or quantitative reasoning which would be the type
of reasoning of a physicist. Those would also be the kind of reasoning one
would need to be able to throw a rock and hit something or to throw a projectile
and hunt for food. Basic survival skill of all Hominini not unique to
males at all.
Before someone reading this dismisses the above as some
wildly PC SJW thing that the left would love. As I have written about on this
blog for some reason I cannot fathom the activist transgender
community does not like these findings either. Because of an ugly history
of health care providers using various arbitrary measures to gatekeep and decide
if someone was trans enough to receive care. Science does not care about PC
or not PC… SJW or alt right or antifa. Science just is.
Sex determination is more complex than XX and XY. The problem
is what happens when things don’t go to plan. Sex determination involvesnumerous
genes and hormones and the timing of such activations. Some large variations in
these processes give us intersexed people. Smaller more common variations
probably give us lesbian, gay and bisexual people. In between those we get
people who are transgender or transsexual. People whose brains tell them they
are to behave as the opposite sex does. Whatever that may be in each
culture.
Research on transgender brains has opened a door to what
would otherwise be too un PC to ever try. To put people into MRI and FMRI
scanners and look for fundamental differences in the brains of men, women, and
XX people whose brains tell them they should be male and XY people whose
instincts tell them to be female.
There are differences between male and female brains …. That have NOTHING
to do with raw spatial and logical reasoning ability.
So if the only differences are things that relate to body
self perception and reproduction what is with all the other differences between
men and women.
Most of those are cultural.
·
In many non western cultures science is seen as a feminine thing
to do.
·
In past decades in the US computer science was women’s work.
·
In our society we have this idea that women belong in the kitchen
doing the dishes, laundry and cleaning.
o
Unless men are in the military then of course they did all of
that.
o
Then when all the men were in the military we had women like Marilyn
Monroe build aircraft.
CULTURE dictates much of what we call gendered behavior.
Gender identity is merely the sense ones brain gives them that they should follow
one or the other cultural role.
In our culture, western, modern culture, science is for men
as much as blue is for boys.
You mean cos-met-tology right?
Like I said I never published science as a male. I lived
as an adult male presenting male for a couple three years at university forced
by circumstances to try and make that work. Then when I moved back to Chicago
I was able to be me again. One of the things I had to do was… lets just say… I
picked up generous men at a particular bar on the north side of Chicago. (I am
a transsexual. Having a high education does not negate certain realities of
being like me when I lived.)
Often I would pretend not to speak English and say what
little Spanish I knew and let the man fill in the blanks.
Other times I would pick a guy who was nervously looking
down at his shoes and work on him to bring him out of his shell.
At least one time I made out with someone who I was sure was
a man with nice eyes … but I am now pretty sure was transmasculine but lives as
a woman much of the time. (Wouldn’t know to look at them in either mode.)
Then there was a very common type of exchange. Some nights
I would simply be honest about who I was, and what my goals were IF
someone engaged me in real conversation and asked who I was .
I’d give them my stage name and say I am at university studying
theoretical astrophysics and cosmology.
Then inevitably they would
say “You mean cos-met-tology ….right?” or something of the sort.
So much for being on the supreme court 40 years from now. Surely
by then some of the above will not be PC anymore.
