Here is the data for transwomen in female sports.
SelfID would have 5 x greater effect on female tennis than on male tennis. It would have 100 X greater effect on female football than on male football.
@DavidTriesman
"Eligibility criteria based on gender identity, rather than biological sex in these sports do not therefore appear justified, balanced, or even possibly legal in Britain."
Cathy calculated the numerical impact on athlete numbers based on population data. There was, because it's tricky to work out, no adjustment for relative advantage/disadvantage in the opposite sex category.
I think the effect at the elite female level will higher.
Cathy reports, in athletics, 137400 male and 73500 female athletes. If 1.34% of males selfID into the female category, that's 1841 males from the male cohort>female cohort.

@Hogshead3Au @BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 OK.
Fitness data from over 85k AUS children aged 9–17 yrs showed that, compared with 9 yr females, 9 yr males were 9.8% faster in sprints, 16.6% faster over 1 mile, could jump 9.5% further, could complete 33% more push-ups in 30 s and had 13.8% stronger grip.
@BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 Here is my full description of that data.
Example:
1.6km timed run (CV endurance)
The *best* 17 yr old girls are matched by *average* 17 yr old boys, and beaten, by some measure, by the best 9 yr old
@BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 Male advantage of a similar magnitude was detected in a study of Greek children, where, compared with 6-year-old females, 6-year-old males completed 16.6% more shuttle runs in a given time and could jump 9.7% further from a standing
@BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 In terms of aerobic capacity, 6- to 7-year-old males have been shown to have a higher absolute and relative (to body mass) VO2max than 6- to 7-year-old
@BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 Pre-puberty performance differences are not negligible, and could be mediated, to some extent, by genetic factors and/or activation of the hypothalamic–pituitary–gonadal axis during the neonatal period, sometimes referred to as “minipuberty”.

Happy Monday everyone :-) Let's ring in September by reacquainting ourselves with Virginia neo-Nazi and NSC Dixie affiliate Sayed "Robbie" Javid, now known by "Reform the States". Robbie is an explicitly genocidal neo-Nazi, so lets get to know him a bit better!

THREAD: 12 Things Everyone Should Know About IQ
1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE
2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less. https://t.co/UqtS1lpw3n
3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)
(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)
4. IQ predicts many important real world outcomes.
For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3
5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)

Hindu villages of Jasrota, caused rebellion in Jammu, attacked Kishtwar.
Ancestors of Raja Ranjit Singh, The Sansi Tribe used to give daughters as concubines to Jahangir.
The Ludhiana Political Agency (Later NW Fronties Prov) was formed by less than 4000 British soldiers who advanced from Delhi and reached Ludhiana, receiving submissions of all sikh chiefs along the way. The submission of the troops of Raja of Lahore (Ranjit Singh) at Ambala.
Dabistan a contemporary book on Sikh History tells us that Guru Hargobind broke Naina devi Idol Same source describes Guru Hargobind serving a eunuch
YarKhan. (ref was proudly shared by a sikh on twitter)
Gobind Singh followed Bahadur Shah to Deccan to fight for him.
In Zafarnama, Guru Gobind Singh states that the reason he was in conflict with the Hill Rajas was that while they were worshiping idols, while he was an idol-breaker.
And idiot Hindus place him along Maharana, Prithviraj and Shivaji as saviours of Dharma.
