Those studies don't prove anything but I believe that culture and circumstance play a large part in determining mobility.
The funny thing is that in ten or twenty years when artificial super-intelligence arrives, everyone, even rich intellectuals, will be, relatively speaking, mentally challenged, compared to the AIs. Please review this video to get a good idea of what I am talking about: http://www.youtube.com/watch?v=I_Juh7Xh_70 (Unless we augment our intelligence with implanted technology of some sort.)
"Such competence is potentially heritable and is reinforced by the human tendency to mate with partners of similar traits and ability."
I simply alluded to (and then later asked) my respondent to what extent he or she is willing to defend equality over an individual's rights. Please do not misrepresent my words. Maybe you should try staying on topic before pointing me to some far-off, yet to be encountered political dilemma? I also pointed out that despite our modern acceptance of evolution, the “enlightened” liberal-democratic west is in absolute cognitive dissonance when it comes to reconciling such theories with the various inequalities that arise between peoples. Perhaps you can enlighten us all with your futuristic wizardry? I'm betting not...
Fight, fight, fight, fight!
(Admittedly, I've seen more evidence in favor of AI than in favor of eugenic/dysgenic hypotheses of social inequality.)
Or perhaps, instead, do you feel that the overall effect on society is not as important as the individual's "right" to maximize his or her own opportunity? And if so, what about some other individual's right to choose the best available mate?
Or is there a third way?
Thank you for the response.
