Re: disparaged 20% of the workforce as biologically inferior
Where did he do that? He did not. This is very muddled thinking.
Every individual is good at different things. Yes, there's a belief in some quarters that every individual is really exactly equal in every capability, but that's nonsense.
I am not disparaging Albert Einstein as inferior if I said he was a brilliant physicist but a mediocre violin player, or disparaging Yehudi Menuhin if I say he was a brilliant violin player but a mediocre physicist.
But if I am employing physicists I want brilliant physicists, and I don't give a damn about their violin playing.
Lets say that people with gene 123alpha6 are more likely to be good at physics than people without it, and people without gene 123alpha6 are more likely to be good violin players than those with it. And lets say that I want to employ people from the top 10% of the population as regards competence at physics. That top 10% of the population will have more people with gene 123alpha6 than the population at large, so if I employ a random selection of the worlds top 10% physicists gene 123alpha6 will be over represented. Does that mean that the ones who don't have gene 123alpha6 are somehow inferior? No, it does not. They are still in the top 10% of the worlds physicists, they are not inferior at all, and its quite possible that the best physicist in the world won't have gene 123alpha6. And incidentally the presence or absence of gene 123alpha6 is actually no use when recruiting physicists. If I were only to recruit people with gene 123alpha6 then I would be automatically excluding a lot of the worlds best physicists from consideration, and end up hiring people who weren't such good physicists even though they did have that gene.
What you are doing, effectively, is claiming that this guy was saying that physicists without gene 123alpha6 are biologically inferior. But he was not saying that at all. And even worse you are making a value judgement that violin players are inferior to physicists, which is appalling. Someone who is good at a one specific job isn't biologically superior to someone who is good at a different job. If you say they are that's pretty appalling too.
