I like Francis Collins's response though, saying that experts believe that the black-white IQ gap is "primarily" due to environmental, not genetic, factors. Either he was being very skillful here, or he was making an attempt to summarise results of surveys of expert opinion.
He basically referred to opinion from this survey which finds about 80% environment as mean estimate, but this question was about international gaps not USA black-white. Expert opinion on the latter is 50-50, not primarily environmental.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4804158/ …

Genetics and environment are a false dichotomy though, american blacks have lower IQ partly because black women dont select for IQ because of welfare and other cultural factors.

The research done by the International Society of Intelligence research found a mean value of 47% genetics, what research showed 50-50?

Not done by ISIR, it's Rindermann's survey.
