Well, there is implied and there is inferred. What he was saying and what people thought he was saying may well be different things. His comment about employees certainly suggested he may have meant less intelligent, though the only terminology he has ever directly used is 'different' rather than 'less'.
Regardless, hs is eminent, qualified and successful enough of an expert in his field that his comments always deserve consideration and I would certainly be interested to know about the evidence underpinning it.
However this seems to be very hard to find. Unfortunately this thread has assumed he meant IQ testing, which then diverted into an entirely pointless discussion o the value of IQ tests which was a waste of time as, as far as can be made out, I cannot see any reason to think they are relevant at all to what is being talked about.
But the heart of the matter is this- Watson, an expert on things genetic, thinks that 'intelligence' (a complicated area) will be demonstrated to be directly influenced by genetic factors within the decade, and that these factors will have a direct relation, due to the evolutionary process, with skin colour. Right or wrong, he certainly has the nous in that area to pronounce upon it and comment upon how things may be if this very much is so. And it is certainly something to consider- what if it IS true that average intelligence can depend on such factors? IF it is true, there's no point running away from it. If it is nonsense, let us show it to be so.
There is a lot of expert testimony to the contrary, of course, and this can be thrown back at him. But there is no point knocking IQ tests when we don't know if that is the issue or talking about cultural factors with black people which also is not the issue.
