Unfortunately, we live in an age where its politically incorrect to remotely hint at genetic determinism. Men and women are exactly the same. Dumb people and the ultra smart are exactly the same. Articles that contradict this don't get much traction in the media and certainly don't get on the front page of HN.
We're probably a generation or two away before we can accurately look at these issues without activist groups and other political groups declaring them invalid because of misplaced idealism.
Somewhere there's a modern day Galileo saying "but some children are born smart!"
The problem is subtler and worse than simple censorship. A person who concludes the "wrong" casual effect from the data is branded a racist or at least under suspicion. A person who concludes the "right" causal effect might face criticism but at least is not in danger of being labeled an evil person. Such a lopsided set of incentives creates a very strong bias. In my opinion this bias is much stronger than the bias ("racism") that it evolved in response to.
