"These and our other results, together with the failure of whole-genome association studies of g to date, are consistent with general intelligence being a highly polygenic trait on which common genetic variants individually have only small effects." This doesn't seem like a surprising result to me. What is being claimed is not "intelligence is not genetic" but it is that "heritability of intelligence is complex". For something that appears as complicated as human intelligence, wouldn't this be expected?
