Now the substance:
"The alleged “suppressed control group” does not turn the result into “no heritability”."
=> Of course not, did anyone claim there was no heritability? But
1/ It's not "alleged", it's printed black on white in the paper.
2/ There is no excuse for suppressing control group data (it's like suppressing the placebo arm of a drug study).
3/ It does turn the result into "junk", and it does establish a definite case of scientific malpractice among people arguing that IQ heritability is 0.70.
As for later analyses, they weren't the topic of my post, but that doesn't mean they're casher.
