Again, it's a lit match and gasoline. I see Wiki has a page on the data, and you'll note the red flag warnings at the top. Disputed indeed.

This can indeed be used to promote racism, and do great harm. I mean think of some kid reading that and thinking he doesn't have chance.
However, it can also be used to combat racism. Apparently, Jews (and that's defined more specifically, basically Jews of European stock) have the highest mean IQ scores. 100 is normalized to be the mean for the entire population, and Jewish mean is about 113. They're almost 1 SD above the mean.
There is a lot of antisemitic stuff about a Jewish conspiracy to control the wealth and take over the world, and that was used for the persecution of Jews. The Holocaust was a result of that. And it still persists to this day in the fever swamps. Well, in most quarters. In some, it's still wide open.
Well, looking at that data, you'd expect them to do the best as a group. And indeed, Jews make up only 1/4% of the world's population, but they account for 30% of the Nobel Prize winners, for instance.
It's a very dangerous subject, but it can be used for good as well as evil.
