You don't. The claims are based on PGS correlations from things like biobank data. Broken record: this is a brilliant product. It promises a marginal improvement in a volatile stat measured meaningfully only when the grown child applies for college. It's purchased exclusively by parents that were already going to fold space like a Guild Navigator to get their kids into selective universities. Heads: you take the credit for them getting in somewhere they were getting in anyways. Tails: there is no tails. It's like a financial derivative product where the underlying is upper-class parental status anxiety. There should be a ticker symbol for it.
