First of all; terrific presentation. #NoThankYou

@TennisBoyfriend @BarryTizer @SerioJoshehe Nah.

Classifying you as part of the human race is as much bioessentialist or fatalistic as classifying you as a male or female.

I'm assuming you dont believe we can transcend that classification.

[Olivia Grunen @OGrunen]

@TennisBoyfriend @_garryforest @SerioJoshehe Believing 'gender' means something else than that makes it a "metalhysical" claim - here meaning equivalent to the belief in a human soul

[Olivia Grunen @OGrunen]

@TennisBoyfriend @_garryforest @SerioJoshehe 'Gender' was/is simply the socially unfolded term for a given sex (e.g. a human female who has grown up in culture X in years y-z, etc.). Genders are 'treated differently' due to gender roles expectations (social settings) which are based on their sex.

[Olivia Grunen @OGrunen]

@rejserin @RussiaColluder @jk_rowling Why are you suddenly arguing against yourself?

The brain is the body. The body is either male or female. The brain can't be mix and match, categorically.

No (brain) behavior is necessary nor sufficient for being a man or woman. Saying so *would* make you a dualist.

[Olivia Grunen @OGrunen]

@rejserin @SwarmZyz @jk_rowling Pick a lane.

Your version of what being transgender is is either 1) as much bioessentialism (you claim that a male's brain can somehow be female, which to you is a biological fact) as sexual dimorphism, or it's b) based on gender as purely a social construct (a psych phenomenon)

[Olivia Grunen @OGrunen]

@Marzipanijah @ShowerMoldHaun @WatchingLurker @mountainatnight @_samanthalux Uhh... or your study just shouldn't conclude something left-field when parameters aren't controlled 🤷🏼‍♀️

It's the scientific method.

Controls are there for a reason.

Your brain isn't something apart from your body. Hence why a male can't have a female brain.

[Olivia Grunen @OGrunen]

@ShowerMoldHaun @WatchingLurker @mountainatnight @Marzipanijah @_samanthalux I guess you didn't read it... or you're not accustomed to articles like this.

Read again where they got the comparative cohort brain scans from.

[Olivia Grunen @OGrunen]

@aldestrawk @againstgrmrs Curious to see what you think I got wrong...

[Olivia Grunen @OGrunen]

@aldestrawk @againstgrmrs I know the study 🤣

My criticism was in the questions.

You should be asking these questions of a study like this.

[Olivia Grunen @OGrunen]

@aldestrawk @againstgrmrs ... and the fact that the comparative cohorts were not even controlled for "gender identity" (let alone co-morbidities or other confounding psych/behavioral factors) should worry you. A lot.

[Olivia Grunen @OGrunen]

@aldestrawk @againstgrmrs Why do you think I asked you those specific questions?

If you're scientifically minded, introductions like "The current study was designed to shed further light on the question of whether the brains of transgender people resemble their birth sex or their gender identity." ...

[Olivia Grunen @OGrunen]

@aldestrawk @againstgrmrs What do you think "trans" is?

Within the parameters of a study akin to this, say.

[Olivia Grunen @OGrunen]

@aldestrawk @againstgrmrs Yes... my point is that that makes any conclusion like the one it posits unscientific.

You should want robust data - anything else won't help your arguments.

[Olivia Grunen @OGrunen]

@SemTuInkognito @Cowboy_Larrie @thepearjoseph @_samanthalux What kind of neuroscientist are you?

We definitely, 100% *don't* know that.

"Switched brains"? 🤔 sounds very scientific, could you elaborate?

[Olivia Grunen @OGrunen]

@aldestrawk @againstgrmrs I'm sorry ... did you claim that no one claims a gender identity between the ages of 23-72?

What is the definition of "gender identity" that they ask their participants about?

[Olivia Grunen @OGrunen]

@aldestrawk @againstgrmrs Co-morbidity control is a cornerstone control for comparative brain studies.

Or else: your conclusion can't be drawn

Has to be controlled across cohorts - otherwise, what you might be seeing is that "trans" cohort aligns with "non trans" on [insert other psych factor]

[Olivia Grunen @OGrunen]

@Marzipanijah @WatchingLurker @ShowerMoldHaun @mountainatnight @_samanthalux How many years after the study do they recheck their compared cohorts to make sure they don't deviate from the original designation?

Any participant down the line claiming to be "non cis" immediately makes the study defunct.

How many studies control for sexual proclivity?

[Olivia Grunen @OGrunen]

@ShowerMoldHaun @mountainatnight @Marzipanijah @_samanthalux Nope.

A brain is female or male because it's situated in a male or female body.

If you say a male "has a female brain", you're literally just re-affirming why the male vs female brain theory was debunked.

[Olivia Grunen @OGrunen]

@WatchingLurker @ShowerMoldHaun @mountainatnight @Marzipanijah @_samanthalux If you're so sure "structure" is a necessary (or sufficient) marker for "gender" then that had as much validity than claiming brain size/volume does.

[Olivia Grunen @OGrunen]

@WatchingLurker @ShowerMoldHaun @mountainatnight @Marzipanijah @_samanthalux How do they delineate the comparative cohorts for these studies?

I'll tell you: they divvy those cohorts into males and females. They do not do extensive surveys on whether those participants "feel" like they're men or women.

Those studies fail by trying to compare 🍎 to 🍊
