A recent president of the Behavior Genetics Association (which hosts an online group of which I am part) saw the same press release, and commented,

"Dopaminergic Polymorphisms and Educational Achievement:
Results From a Longitudinal Sample of Americans

"Here is my question: if a linear combination of three environmental measures-- books in the home, air quality and hours spent watching TV-- correlated -.12 with educational achievement, would anyone take it seriously?"

There seems to be a lot of grasping at straws in current genetic studies of human behavior. The more genes are investigated across more individuals, the less each gene appears to have to do with any behavior of interest.
