I get what you're saying - kids aren't code to be optimized with objective best practices. But on the other hand, it's very head-in-the-sand to think that parenting with the best intentions and love will always have a positive outcome. It's a good course of action for guaranteeing a happy childhood, but unless you're so affluent that your kids are assured a life on easy street, happiness isn't your only responsibility as a parent. May be that love and fun is all the kids need to be both happy and successful, but maybe not: I had very hippyish parents who didn't go much beyond love and fun and blind support. Myself and my two siblings all had very happy childhoods, but only my very self-motivated sister wound up finding success and happiness as an adult right off the bat, took me a decade to get my footing, and my brother - who was unquestionably the happiest and most loved kid in the family - is a broken and miserable adult. Ultimately it comes down to regarding your kids as individuals and tailoring your parenting to each kid, which is what this study is trying to help parents do w.r.t. smart kids.
