DNA differences being the cause of higher or lower IQ's of different races is totally understandable. But I myself dont believe that the difference would be anything to hold one race back while another has an unfair advantage. It's obvious that social constraints is the biggest reason for the success or failure of a race as a whole.
And the worst part that I hate about this article is that they state the obvious that scientists and geneticists will now be somewhat held back from showing their results, in fear that they will lose funding. So now, being "politically correct" is more important that advancing the sciences and telling the truth of studies.
Sad.
