Ah, interesting, thanks for posting that Bostonian. Recent enough, though, that not only will I not beat myself up for not having known about it, but also, I will continue to regard the book under discussion as snakeoil, because at the time the book was written, we didn't know with any confidence what genes were important. (And now, it looks as though there are so many genes involved, each with low individual importance, that you'd have to be showing that some environmental factor turned on many of them for that factor to have a measurable effect by doing so, probably.)
