content: IQ doesn't just revert down to the mean naturally-- it is largely inherited, so as long as both parents have reasonably high IQ the kids will too. It's not like some outlying factor that always has to revert to the mean  If both parents are outliers, the children's iq will revert roughly to the halfway point between their racial mean and the parents' IQ E.g. If the parents have an IQ 2 standard deviations above the racial mean, the offspring's IQ will be on average one standard deviation above the mean
