The authors of the GREML study do not address the possibility that performance on the intelligence tests correlated with social status, which is a highly heritable trait but for reasons completely unrelated to biology.

Essentially any evidence based on a Genome-Wide Association Study should be regarded as suspect. They use extremely simple population-genetic null models, and it's extremely rare for them to turn up novel, testable biological insights.
