No time to comment. Yes, the hits with SNPs are cool. But look at all the functional associations and analysis in this paper! Some serious biology in this. The figure from the paper to the left which shows how the genes associated with this SNP hits are expressed in different tissue/types and organs. These are the biggest effect SNPs for years of education in the genome, so it makes sense that they’d be way over-expressed in the brain. It is definitely more convincing to those who might be skeptical a priori than some statistically robust associations (well, it should be more convincing at least).

Genome-wide association study identifies 74 loci associated with educational attainment:
