After over a century of psychometric research in cognitive abilities and intelligence, what do we have to show for it? Whose life has actually improved for the better? Have the benefits from such research, if any, outweighed the amount of harm that has already been caused?
Who is more likely to have more time and the means to develop patents? The high income/high intelligence person who pays for others to do various chores, labors, and services for them so that they may focus on their work, or the people deemed unworthy by society who spend their time performing the chores, labors, and services for the high income/high intelligence person?
I believe intelligence alone is worthless, if not dangerous, without altruism and empathy. As I type this very message, somewhere in the world, there are people being torn to shreds, families destroyed, etc. by various contraptions designed by some of the most intelligent people on the planet. While unintelligent people may have less potential to change the world in a positive manner, it is apparent that those same individuals have less potential to change the world in a negative manner, as well.
Whatever potential these children have, I believe it's imperative that we are damn certain those children have the moral and ethical composition deserving of their potential, at least, that is my starry-eyed opinion.
