In response to
I wrote this in the comments section:
"In my previous comment I said that the video was really interesting but could give the wrong impression. However, as much as I want to assume that Molyneux has good motives, I think that his stance on race and IQ is counter productive. It is not just that this is a taboo subject, but it has great potential to do harm. Even if it is true, there is no benefit to repeatedly pointing this out and it gives fuel to racists and justifies the idea that we can treat people differently based on race. People should be treated as individuals based on their individual merits and race should be a non consideration. Pointing out differences in race creates prejudices in otherwise well meaning people who had none.
There are a huge number of factors that could affect scores on IQ tests. I don't think that I need to list them. As a result, the premise that intelligence varies by race is essentially unprovable. Over the next hundred years we will see populations shift and changes in demographics and economics, and therefor I suspect that a hundred years from now we will see dramatically different results on these kinds of tests. If correct, it makes race based comparisons rather meaningless."
