Thos needs a better title. Suggest "Support Data Colada' legal defence fund. Blogger's rigorously investigate academic fraud, sued by fraudster."

9% decrease in response time would be pretty significant for gamers.

Look out for LED illuminated gamer branded helium tanks.... and if you think online gamer chat is annoying now, wait until you get called a noob in a super high pitched voice.

If someone asks about how to read sheet music faster, and you can't read it, it's ok to just not say anything

Why does everyone find much stronger genetic effects than parental in adoption studies?

“Little intergenerational correlation in education was observed in the absence of genetic similarity between parent and child—that is, among adoptees.”

https://gwern.net/docs/genetics/heritable/adoption/2021-lude...

“By examining parent-offspring resemblance in a sample of offspring that are among the oldest of any adoption study of IQ to date, we have effectively tested for the presence of parenting effects that would have persisted for more than a decade after the conclusion of the typical rearing period. No such persistence is found to occur in our unique sample.”

In an adoptive sample of Korean Americans parental income was unrelated to offspring income.

What's your explanation for the over-performance of the Ashkenazi and Chinese vs US whites?

I doubt matching for education matches for potential. An American who drops out of highschool is not the same as a malnourished African who never had the chance

It's going to almost impossible to match backgrounds between the two groups and selection effects are huge.

Another question is what are people owed if someone's ancestors were under artificial selection by slavers for many generations?

I think a claim there may be legit. However I'd rather keep objective admissions and hiring and just give cash transfers. I can understand though that people want status as well as cash

There are also cultural differences, I would bet they have different mindsets of 'grievance' vs 'opportunity' towards the USA

It would also be hard to not be affected by selection effects, eg compare Obama's dad who came to America for an economics PhD at Harvard vs someone whose ancestors were enslaved for hundreds of years

Nobody has ever claimed a 100% genetic basis of difference. The individual heritability of IQ is .5 to .8 for example

Sub-Saharan diversity is a real thing, eg Bantu, Nilotic, Pygmy and Bushmen are extremely diverse (African Americans are not Pygny or Bushmen so not as diverse)

But if you use cluster analysis on human genomes and ask it to divide humanity into 2 clusters, it divides humans into Sub Saharan Africans and everyone else.

The key is selection not just randomness (most variation does little or nothing) you can't say eg "Africa is the most diverse therefore it will have the best adaptations for altitude" (that would be Tibetans, courtesy of interbreeding with Denisovians)

The number of variants responsible for skin color is actually extremely small. It's why you can have such large variation between siblings.

In contrast yes intelligence is highly polygenic. However, given sufficient sample sizes you can calculate genome wide association scores and work this all out.

It also relies on blank slate theory - ie that all groups should perform equally, and if they don't, that's evidence enough that there is a conspiracy against them.

Perhaps a way to test the "different groups have different abilities" vs "past bias" theory, would be to find people with high IQ / historical record of accomplishment who suffered great historical discrimination and deprivation (eg Ashkenazi Jews from the holocaust, Chinese families purged in the great leap forward) and then compare their descendants test scores and job outcomes in the USA.

You could look at outcomes a generation or two afterwards and tell whether their performance was high/low ie was "reversion to high group accomplishment" or "underperformed due to present or previous oppression"

Thanks for pointing out the date, I was shocked at how un-woke it was for a mainstream news article.

The mRNA vaccine took only a few days to design. So you'd save a few days, if the GoF virus happened to be exactly the same as the wild type.

There is no way to rush the rest of the process, unless you want to deliberately expose people to artificially created viruses that don't exist in the wild.

Small upside vs large downside of potentially creating a global pandemic.

Covid appeared on the Wuhan institute of virologies doorstep, with exactly the modification proposed in their grants. You would think this would be their time to shine but where was their help?

Right when the world needed the info they took all of their databases off-line and have never opened them again
