If this result, just published in Cell Reports, is confirmed, KL-VS will be the most important genetic agent of non-pathological variation in intelligence yet discovered.
IQ != intelligence. If you want to study variations in IQ score, fine. Not saying it can't yeild interesting results. But can we please stop pretending that there is anything approaching a useful scientific definition of intelligence, nevermind one that reduces to a single number. That ways lies the kind of idiocy that will end up with people fucking up their kids genetic structure trying to engineer "intelligence" without even understanding what that is.
