@MPMacLachlan @PuppyDogma @lecanardnoir @Atomtoplanck @JoeBeck99398028 @beigepilled @LolOverruled Ok, let's do this with a practical example - humans - and some fairly advanced developmental biology.

So, phenotypic sex development begins at around 3 weeks after conception with the development of a few basic structures:

- bipotential gonads, which (in normal development)... @MPMacLachlan @PuppyDogma @lecanardnoir @Atomtoplanck @JoeBeck99398028 @beigepilled @LolOverruled ...will go one to become either testes or ovaries.

- Mullerian duct, which (in females) will develop into the fallopian tubes, cervix and upper portion of the vagina.

- Wolffian duct, which (in males) will develop into the epidydimis, vas deferens, ejaculatory duct and...

I've had time to look a little bit more closely at the demographics of the CambU/BMJ paper I refer to in this thread and picked up a couple of points of interest, one of which may support Michale Biggs' contention that there may be some reliability issues with the Census... /1

...data from the new Gender Identity questions.

One point I initally picked up was an apparent issue with the presentation of the age demographics in CambU's press release. This claims that trans/non binary people are more likely to be younger and supports that by stating... /2

I've tracked down some advanced GK stats which offer some interesting insights into both the performance of our keepers this season and the difference that Carlos Corberan has made since taking over from Steve Bruce.

We're looking at Championship games here, so before... #wba ...last night, Button (DB) played all his games under Bruce while Palmer (AP) played 1 game under Bruce, 3 for caretaker manager Richard Beale and the rest under Corberan.

On the basics, goals conceded per 90 mins and save percentage, AP has a very clear lead over DB. ... #wba

Okay, so who's up for a bit of Sunday morning stats nerdery?

I've been poking around in the Census 2021 data on Gender Identity and found a few interesting features that are worth commenting on.

Let's start with something I'll come back to later, the rate at which people... /1 ...chose NOT to disclose any information in response to the Gender Identity questions, which was 5.73%.

Now this is not the only voluntary set of questions in the Census, respondants can also decline to answer the questions about religious belief and sexual orientation.... /2

Okay, so let's get into this properly, even if I've got to QT so I can make the threading work.

So the whole chair/horse/whatever definition argument rests on the assumption that any attempt to construct a precise definition of an object, such as a chair, will inevitably... /1

...to an infinite regress, i.e. no matter how long and detailed the definition there will always some other object which satisfies all the criteria specified in the definition, creating a reductio ad absurdium.

This may indeed be true when dealing with formal axioms in.... /2

Okay, so this is the key section from the Albion Assembly minutes dealing with the club's finances, in full, so let's break this down properly.

We start with the £4.95 million loan to Lai's Wisdom Smart, which we're still being assured will be repaid by the end of... /1 #WBA ...the year, with the funds being made available to strengthen the squad.

First, this is a clear test of Lai's credibility. If the loan isn't repaid then he has none, simple as.

If it isn't repaid then it's difficult to see where Gourlay goes from there. I can't see... /2 #WBA

One thing being missed in the reporting of the Laurel Hubbard story is a glaring anomaly in the current IOC regulations governing the participation of transgender athletes in Olympic event, on which this graph clearly illustrates.

The graph shows population distributions... /1 ...for circulating testosterone levels for normal healthy females, females with PCOS and/or hyperandrogenism, and for normal healthy males, all based on current IAAF reference ranges.

I've also added the following two lines:
