In many twin studies, broad heritability of IQ is .7-.8. If polygenic scores can capture almost all of that heritability, their prediction of IQ won't be perfect, but will very good indeed. Obfuscation abounds, but if those predictions work, I don't see how one gets around them

The polygenic scores don't even come close to explaining as much variance. They still only predict less than 10% of education. All the current hype is a marketing campaign by genetic testing companies.

Of course they don't come anywhere near capturing that much variance -- today. We have no compelling reason to believe, today, that they won't in the future do so -- though perhaps rare variants may pose a real problem.

Rare variants are easily captured with deep whole genome sequencing. It is expensive right now, but price is falling very quickly. https://www.genome.gov/sequencingcostsdata/ …pic.twitter.com/7SDIU4Q6sZ
