It’s a factor and I think those that argue against it overshoot their case by completely dismissing it altogether. Yet to argue that it’s a large factor you have to explain all the many cases of genetically almost identical populations with vastly different outcomes across either space or time. By time I mean historically. Europe was a lot poorer than much of the Muslim world and the Orient until the enlightenment and the industrial age. Did Europeans suddenly mutate into a higher intelligence population? Russia has been in steady decline since probably 1980 or so. Their ethnic makeup has not changed to any significant degree. China exploded in the past 30 years. Probably even less genetic change there. North and South Korea from space is the most dramatic example. That has an obvious political cause but the genes are about identical. The variance in societal scale outcome just does not map well to human genetics, revealing it as a minor rather than a major factor.
