I would interpret your graphic as demonstrating that intelligence is at least somewhat heritable. If your parents did well in school (at least got more of it) then the probability is that you will do so too.

One might draw from this that there are cultures which thrive in an educational environment, and those that don't.

While some might try to tie results to race, it appears that race plays a smaller part than cultural factors.

Abominable. One would think that the bright parents [those with graduate degrees, especially the Asians with their cultural premium on learning] would get their progeny into 1450-1600 SAT range, and instead they are merely in 1000's, I remember the Duke Louis of Orleans rueing the numbers of "people of low degree and doubtful birth" - and even 610 years ago he surely knew what he was talking about. The degrees, even if graduate, are low, and the births are doubtful, too.

What's even more telling is that the 1995 SAT Score chart only goes up to 1100. Why did they not include the full range? Perhaps a little problem with the bell curve?
