> This side of the veil, instead of looking for the “gene for intelligence”, we try to find “polygenic scores”. Given a person’s entire genome, what function best predicts their intelligence? The most recent such effort [citation in the original article] uses over a thousand genes and is able to predict 10% of variability in educational attainment. This isn’t much, but it’s a heck of a lot better than anyone was able to do under the old “dozen genes” model, and it’s getting better every year in the way healthy paradigms are supposed to.

I think that's a much more measured claim than you're giving credit for; "it works" is claiming to explain 10% of variance. Do you have specific complaints about the cited article? Or are you just arguing by analogy that since people were wrong in the past, they are probably wrong now?
