Not sure what is your point, the "test achievement" mentioned in the document refers to totally different "test" that the ones we were talking about.

Also, on just pure logic, I don't think the document shows what you think it shows. The document you provide (which is 30 years old, so with just this one, we should not assume it reflects today's consensus) explains that the difference is not understood, and that there is no _obvious_ answer, neither from biology, from group culture or from bias in the tests. In other words: the difference is due to something _not obvious_, for example (but not limited to, of course, it's just an example), _not obvious_ form of bias.
