DNA co-discover puts foot in mouth over race-intelligence issue

It’s hard to believe that someone of the stature of James Watson would say this in public, just as it’s hard to grasp that someone of his learning would believe it, but the Nobel laureate and co-discoverer of DNA apparently believes in a black-white intelligence gap. And, by referencing both black Africans and African-Americans, the clear inference is that he believes this is race-based and not culture-based:

Watson, an American, sparked uproar by telling Britain's Sunday Times he was “inherently gloomy about the prospects of Africa” because “all our social policies are based on the fact that their intelligence is the same as ours — whereas all the testing says not really.”

The 79-year-old geneticist said he hoped that everyone was equal but countered that “people who have to deal with black employees find this is not true.”

I think “unbelievable” is the only thing to immediately come to mind.
Beyond that, the fact that Watson apparently believes there is a core, definable, and already defined “g” measure of intelligence, and that he also believes intelligence tests measure it, show that the width of his genius-level knowledge is narrow, indeed.

The first precept is hotly questioned, especially the part about whether we have defined what “g” is. The second precept is not just questioned but actually rejected by the majority of psychologists, psychiatrists and neuroscientists that study human personality testing.
