An important review.

Considering Sex as a Biological Variable in Basic and Clinical Studies: An Endocrine Society Scientific Statement | Endocrine Reviews | Oxford Academic…
All serious scientific agencies are outlining requirements for clear definitions of sex as it pertains to biology studies.

The Endocrine Society is not the first to make such statements, but this is comprehensive.
Many guidelines, including those from the NIH and the European Commission, demand separation of sex from gender (where the latter is irrelevant in all non-human studies).

And demand clarity on both sex and gender.
While I hope we all understand the necessity of including sex in biology studies, I await the inevitable backlash from people who think their gender identity will protect them from COVID and CF deaths.…
NB. Biology nerds go and look at the 4 Core mouse model. It’s fab.

The number of people displaying an abject lack of knowledge about the history of colonialism in Africa is frankly mind blowing.

Do you not look at maps? Wonder about languages and town names? Read any books by African writers? About economics? About foreign aid?
Never curious about the various secessions or civil wars? The stripping of mineral resources?

I am no expert, not by a long shot, but how on earth do you avoid it?
I’m not arguing that the average person should have in-depth knowledge. I’m asking how anyone can express surprise at older colonial territory maps and not look phenomenally stupid.

‘there is no consensus criteria for assigning sex at birth.’

Peak idiocy. Right there, the most stupid thing I’ve ever read.…
I. Just. Can’t.

The conformation of external genitalia has extremely reliably permitted sex identification from birth, and increasingly, in utero.

A kid could do it. And get it right almost all the time.
The demand that the world bows to ‘assigned’ is because some people don’t think physical anatomy reflects whatever bonkers idea of ‘sex’ they wish to promote.

@MediClit The key with socialisation is that one is not making a truly free choice. It can feel like a free choice, it can framed as one, but socialisation constrains the options, even if one does not realise it.
@MediClit Lots of women are afraid to speak intimately about their anatomy. That’s the result of years of being, say, teased at school, told that vulvas/vaginas smell, that being hairy is ‘gross’. It all impacts on how we process stuff and how we respond to stuff.
@MediClit You’ve revealed your medical history. You were socialised regarding how labia ‘should look’. Many women, including me for many aspects, are socialised about how hairy their legs ‘should be’, or that they look old/tired without makeup.

It’s not a weakness to recognise that.

The Phelps Gambit - life’s unfair.

The Phelps Gambit runs like this:

Michael Phelps had ‘unfair’ advantages in swimming, but nobody prevented him from competing, so why should we prevent others with ‘unfair’ advantages (males) competing against anyone (females)?
Here is a thread outlining Phelps’ ‘unfair’ competitive edge over his closest competitors. It runs at less than 0.5%. His advantage over matched females is around 10-12%.

Phelps’ advantages are the stuff of legend, growing from fairly straightforward observations like, ‘He’s quite tall, with even longer arms’ to, ‘He’s got superhuman metabolism and his bones are made of Adamantium’.

(I exaggerate).

Here is a basketball analogy.

Shaun the Shortie/5’5.
He’s not tall enough to reasonably be a competitive basketballer.

Mitch the Middler/6’5. He is tall enough to be a competitive basketballer.

Tall Tony/7’5.
He was nailed on for basketball since he was born.
No amount of skill can make Shaun competitive. There’s only so far it can take you.

Tony? He doesn’t need to rely on skill, because you get it to him and he’s got a free shot every time.
Mitch is where it’s happening. There are quite a few 6’5 basketballers. It’s ‘tall enough’.

In fact, average NBA basketballer height has plateaued at about 6’7 (forgive my analogy a couple of inches).

Appalling arguments from Vilain here.

"We know that men have, on average, an advantage in performance in athletics of about 10% to 12% over women"

This cited advantage is the low end (running). The difference gets much larger in other disciplines. In weightlifting, the gap is 30-40%.
"which the sports authorities have attributed to differences in levels of a male hormone called testosterone"
