So we've gone from 51% to 20% to 14% as the field has learned how to apply these methods more precisely and address confounding. Researchers that raised concerns of environmental confounds and stratification were proven right, and it's unlikely that we've resolved all the issues.

This was echoed by four leading evolutionary/population geneticists in another detailed explainer. Their conclusion: "genetics has only served to undermine its own racist history."

We should care about causes, and race is a poor causal model of human evolution. In truth, genetic variation follows a "nested subsets" model, where all people eventually share ancestors, which is fundamentally different from race (see for yourself here: ).

This thread on human disease architecture generated a lot of interesting discussion and I wanted to highlight some important concepts that we still DON'T know the answer to (mostly suggested by others):

A 🧵 on some of my intuitions/priors about the genetics of complex and molecular traits in humans (i.e. what I think of as typical), largely motivated by GWAS/QTL studies over the past decade [citing papers with nice figures where possible]

-- structured interviews are indeed much more accurate at predicting employee performance with lower racial bias! Unstructured interviews are really bad (as are other seemingly 'objective' metrics like years of experience). "DEI" here was just fair & effective hiring.

@Steve_Sailer 3: Can you address the related finding that diverse hiring without an IQ test can produce equally good job performance? Following your advice makes business less effective!

@NAChristakis Or if this is a serious conversation, perhaps you and the Enron billionaire can inform us how you would restructure Harvard's Math 55 so it's not so grade inflated?

@kareem_carr Yes, it's a huge problem. *Any* mechanism will get counted as heritability, and that will include stuff like discrimination via pigment or staying out of school for an autoimmune disease.

A few years ago I requested access to GWAS summary statistics from a variety of published studies that stated "Data Available Upon Request" and tracked the process: 4 studies, ~40 emails, 2 provided the data, taking an average of 22 weeks. Not great!

The response I received when very kindly asking a Cambridge Prof if they would share their GWAS sumstats, also said I’d include them as coauthors on any resulting papers… I.e. no, go and run the whole GWAS again yourself. THIS IS BAD SCIENCE. Also, not even a Dear Emma? Rude.

This was an interesting read from Plomin and Deary on the genetics of intelligence. Notably, they make five predictions about what we should expect to see from molecular data, based on their decades of experience with twin studies. Do they hold up? A 🧵:

I highly recommend anyone working with single-cell data read this and take these issues seriously. These tools are under active development, which is terrific and to be applauded, but has also created a very fractured methods ecosystem. 1/

The choice of whether to use Seurat or Scanpy for single-cell RNA-seq analysis typically comes down to a preference of R vs. Python. But do they produce the same results? In w/ @Josephmrich et al. we take a close look. The results are 👀 1/🧵

Anyone else struggling with conjunctive verbs in their writing: repeatedly starting sentences with "However,"/"Moreover,"/"Likewise,"/"Consequently," etc. And is there a good way to break this?

@patientsnail The entire field looks at this stuff with a mixture of disgust and embarrassment. People are using methods we develop in absolutely idiotic ways, drawing obviously wrong conclusions, never subjecting them to peer-review, and instead passing them around like it's Secret Knowledge.

The author also seems to think the Ravin's [sic] are a silver bullet against the claim of cultural bias, a view that's heavily disputed in the field itself. The cultural specificity of filling in left-to-right matrices should be obvious to anyone who has ever read a comic book.

@charlesmurray Let's get you to bed grandpa. Genetics explains <20% of educational outcomes and the majority of that is via parental environment. Individuals with equivalent genetic scores for education have much higher math achievement in high-SES schools.

Seems pretty simple: 1. Universities really like tests 2. The pandemic made testing more difficult and also hurt enrollment 3. The pandemic is over 4. Universities will always describe any policy change as improving equity

What’s the best explanation for why all these schools turned against the SAT around the same time and why they all re-embraced standardized testing at roughly the same time? (Besides herding behavior)

@paulspivak_ @DeepAlphaeus @MattyDubs7 @whstancil What even is this? Some anon generated a chart in, I guess, a completely different data set with no description of the method or even the effect scale? This isn't even grasping at straws, it's some new worse thing.
