Boring. The effect size of the variants is too small to find with n=10,000, hence any positive findings are almost certainly false positives which will fail to replicate. That's why the 3 SNPs found recently (http://infoproc.blogspot.com/2013/05/first-gwas-hits-for-cog...) were in a sample of n=101,000.

There's nothing here to undermine the view that genetics causes much of variation in intelligence, it's just that the variation wasn't as clustered on a few genes as people hoped because it would make the research so much easier.
