Good link. At the end of the day, they're doing association studies... So they're taking a phenotype (even survey answers are a "phenotype" in a manner of speaking) and correlating it with a genotype (whether SNPs, exome data, or genome data). I'm a believer in this approach to science and am in no way poo-pooing their effort; I merely wanted to comment that, from the article's description of their approach, they're doing nothing iconoclastic.

This isn't a new kind of science, since this is the kind of science that we've been doing since ~2007-2008. They are basically describing GWAS.
GWAS = Genome-wide association studies
