The reason you didn't get a substantive response out of me is because of point #2. You believe that to be so...but that doesn't make it so. In particular, you can't have much basis to believe so, since the genetics of intelligence are, if at all understood, are understood poorly.
Which is above and beyond the fact that studies show that genetics, environment, and upbringing all combine to determine intelligence. In fact, the most important contributing factor to intelligence is diet, not genetics: everything else being equal, if you starve vos Savant's children in their developmental years, they'll basically grow up to be idiots who believe in stupid sh-- like eugenics or Kelly Holcomb's arm.
And even beyond that...I actually had started a substantive response, explaining what "deviation towards the mean" is, and how Marilyn vos Savant's children and grandchildren would more likely than not be average. But I figured, nah, why bother, I already had to dispute this Nazi bull sh-- with KurtGodel77, if you want my opinions you can look them up from back then. But apparently you're not smart enough to research past posts...which I suppose makes you genetically inferior to me.
