      Thanks. Do I get this right: 1% more Euro ancestry increases black IQ by .013 SDs. A hypothetical black w/ 100% Euro

      i.e., it's consistent with genes potentially explaining the entire gap, but obviously it's not super precise

      Why using CA2? IIRC, it's not sex adjusted. Gap seems to be about 1.5 d for full range here. @RCAFDM @pnin1957

          Okay. I changed my mind. I worked out all the results based on this approach and it's a good idea. Will update paper. @RCAFDM @pnin1957

          Good choice. I'd also convert g scores to IQ scale (100; 15) & multiply ancestry by 100 for better interpretability.

          Tricky to convert to IQ because the sample is selected. The g scores are calculated for entire sample so sd=1 is not 15 IQ @pnin1957 @RCAFDM

          in other samples because these are usually based on Whites only. Can't easily do that here due to restriction of range. @pnin1957 @RCAFDM

          Naive conversion to IQ thus: African genotypic IQ = 80. Amerindian genotypic IQ = 88. Lynn will not be surprised... @pnin1957 @RCAFDM
