Their findings are summed up in that link (written in 1994):
1.Intelligence exists and is accurately measurable across racial, language, and national boundaries.
2.Intelligence is one of, if not the most, important factors correlated to economic, social, and overall success in the United States, and its importance is increasing.
3.Intelligence is largely (40% to 80%) heritable.
4.No one has so far been able to manipulate IQ to a significant degree through changes in environmental factors—except for child adoption—and in the light of these failures, future successful manipulations are unlikely.
5.The United States has been in denial of these facts. A better public understanding of the nature of intelligence and its social correlates is necessary to guide future policy decisions.
Note that #5 was never followed, but was ridiculed and deemed "racist" by academia and the media.
The average IQ of US whites is about 100, and the average intelligence of US blacks is about 80 - an entire standard deviation below.
Equatorial African blacks have an average IQ of less than 70. Jews and Asians have average IQs exceeding 100, and keep in mind these are averages (meaning there are significant populations above these scores, as well as scores below).
So in our "Conversation about race" that Obama and Holder want to have, this, of course, is not allowed to be discussed.
It is tried and proven that the wealth of a nation is directly tied to the national IQ.
Therefore, since government, liberals, "activists", the media, and academia preach about "equality" and "opportunity" - we must realize the truth. There are entire populations in our nation that are vastly different in intellect, temperament, and behavior.
Since they base their fiscal, legal, and social policies of this nation (including taxation and spending) on false premises, we are doomed to see even worse failure than we have witnessed.
Now, having said all of that, I weigh in with this: the measure of a human being by God is NOT their gift of intellect, athletic ability, physical beauty, or other trait. It was God Himself who gave each of us our gifts, and our makeup. God speaks of beauty, wisdom, ability in war, etc - assigned to each of us in the Bible. God knows what those things are! He invented them.
But, by the standards of the Gospel and His plan for Salvation, the measure of worth is what we do with His Son.
That is the standard. Someone of another race from me who has accepted Jesus Christ is my brother or sister, while someone who is theoretical genius of any race, but wicked in motivation and selfishness and has rejected Christ, is not.
We live in this world, a fallen world. God's standards are different. But as I currently live in this world, I know that the lies being fed to me regarding crime, race, achievement, wealth, and behavior are simply that - lies.
