Why can we talk about PISA results, comparing the performance of students in school, but we are not allowed to talk about differences in IQ? Bring this subject up, and you are immediately accused of racism. And yet. And yet, if there are substantial differences in intellectual capability, might this not explain some of the world's problems?
An update of a massive "study of studies" is underway; this article summarizes the work to date, and provides links to the work in progress. A quick summary of the answers to the questions no one dares ask:
In the first instance, it doesn't even matter why there are differences. They may be genetic, or disease related, or nutrition related, or something else. If these differences are real (and the evidence is pretty strong that they are), then we need to deal with them. Imagine if the low IQs in Africa turn out to be fixable - what would the impact be, if we could raise the IQ of an entire continent by 30 points?!
Sticking our collective heads in the sand, because the topic is not PC, is not going to solve any problems.

Lots of people claim that whites are over-represented in Facebook and Google, but they are wrong.
Speaking of distribution the average/mean and median are useful for some stuff but not all. Often it's the outliers that matter more. Few care how fast on average white or black person runs. Whereas more people know who Usain Bolt is. Same for Einstein vs some random physics teacher.
But in many democracies the average person's vote often counts as much if not more than the outliers...
