10 people out 550K isn't anywhere close to a statistically viable group in terms of performance against the group and you claim to be smart enough to know that.
Ah - not quite my statistically challenged friend.
If those 10 people were from a group just starting out in the sport, then clearly you'd expect them to be at the
bottom-end of performance metrics.
To take an example - if we considered the lap times of a few Amazonian subsistence tribesmen in F1 cars - they'd rank fairly poorly.
Conversely, if we put a few F1 drivers in the Amazon jungle and evaluated their ability to catch food - they'd also rank fairly poorly.
But if we took 10 F2 drivers and put them into F1 cars, they'd probably do quite a bit better.
Anyway, literally a few seconds on google gives a some examples. Top is probably of most interest as it shows the clear change in relative ability when switching over.
[1]"Just how much of an advantage did
Lia Thomas possesses over biological females? The numbers paint a clear picture. The fact that the University of Pennsylvania swimmer soared from a mid-500s ranking (554th in the 200 freestyle; all divisions) in men's competition to one of the top-ranked swimmers in women's competition tells the story of the unfairness which unfolded at the NCAA level."
[2]"Beggs (36-0), who won last year's Class 6A girls championship in the 110-pound division, won by decision 15-3 against Chelsea Sanchez of Katy Morton Ranch."
The previous year he went 57-0.
Interesting to note that Beggs went from biological female to male. But the rules prevented him from competing against boys.
So its clearly not a case of flat out ignoring gender switches. The issues are a bit more nuanced than that.
I do think think there is correlation between underrepresentation and underperformance
Non-intuitive inverse correlation in this instance!
I'm quite disappointed in general at forum on this one on most other subjects we'd be pushing against that kind of confirmation bias but instead claims with zero backing got tons of likes.
... and be as disappointed as you like. Hiding behind an offended bus does no one any good.
I'm sure there are plenty of parents out there would think twice about letting their wee girls play rugby underage if they seen a large transgender player step onto the pitch.
