           A million views on a post introducing our important new research. It's gratifying seeing the reach this has gotten from just my personal account. Our @herasight inbox is blowing up with interest from couples looking to screen. Very exciting! Thanks to everyone who engaged. 
           Today we reveal CogPGT, the world’s most powerful genetic predictor of IQ. We achieve a correlation with IQ of 0.51 (0.45 within-family). Herasight customers can boost the expected IQ of their children by up to 9 points by selecting the embryo with the highest CogPGT score. 🧵

             Our study shows that powerful genetic prediction of cognitive ability is not only possible but likely to be highly beneficial when applied in embryo selection, resulting in meaningful increases in intelligence as well as reduced psychological problems and disease risks.

             Polygenic prediction accuracy is known to decrease with genetic distance from source data (here European). CogPGT followed this pattern, with correlations decreasing by up to 40% for African-American and East Asian samples, compared to only slight decreases for US Hispanics and

             Some previous results suggested that genetic effects on IQ vary by family background. We found no evidence for this when testing for interactions with family conflict, income, and parental education, suggesting similar effects by family background.

             Higher CogPGT score was associated with lower risk for cardiometabolic diseases, including type 2 diabetes and coronary artery disease. Associations were consistent within-family, implying selecting for higher CogPGT score would slightly reduce cardiometabolic disease risk.

             We found that the average CogPGT score among those in an occupation was strongly correlated with the (CAMSIS) occupational status of that occupation, with medical practitioners and higher education teaching professionals having the highest average CogPGT score.

             We also looked at within-family associations between CogPGT, psychological traits and life outcomes in the UKB. CogPGT was associated with increased education, income, occupational status, friend satisfaction, health, and emotional stability.

             We analyzed off-target effects of selection for IQ by correlating CogPGT with other outcomes, including behavioral phenotypes in 9-10 year olds. We find almost* uniformly beneficial correlations, including reduced ADHD symptoms and autistic traits with higher CogPGT score. *only

             Herasight have set a new standard in genetic prediction of Type 1 diabetes. T1D straddles the boundary between PGT-M (for single gene disorders) and PGT-P (for polygenic). There's an outsized contribution from risk alleles in the HLA region, so in families with a parent that

             In a way the more oligogenic architecture of an early-onset disease like T1D makes it more amenable to genetic prediction and embryo screening, assuming its HLA component is properly modeled. And that was done expertly here. Take a look!

             I don’t think the EAS PRS performances shown in Figure 5 yet justify that statement, which seems to suggest that the best available EAS PRS models now meet or exceed the best available EUR ones. Since these PRSmix+ EAS PRSs were trained and tuned on only 363k + 80k Taiwanese TPMI 
           This is a far bigger deal than people realize. For the first time ever, we've got polygenic scores for East Asians that match or beat the ones we have for Europeans. East Asians doing polygenic embryo selection are no longer at a disadvantage. Finally!

             The mean is not a sufficient statistic for the distribution. Scientific innovation comes from the far right tail. If you don’t admit the best foreign students, you get vastly fewer students in the far right tail. 
           The average IQ of an Ivy League undergraduate is about 125. The total freshman class size of all the Ivies plus Stanford is about 15,000. Each year, 57,000 Americans are born with IQs over 130. We can fill our elite universities with our own higher-quality students.
