Adaptation to environments, including social environments, through natural and sexual selection is the linchpin of evolution. Remembering this means knowing why scientific racism is ridiculous. To argue that races or ethnic groups differ innately in intelligence, however defined, is exactly equal to an assertion that intelligence has proven less adaptive for some people than for others. This at minimum requires an explanation, a specifically evolutionary explanation, beyond mere statistical assertion; without that it can be assumed to be bias or noise. Since most human intelligence is in fact social intelligence -- the main thing the human mind is built for is networking in human societies -- a moment's reflection should demonstrate why this is an unlikely scenario.
(bolded part mine)
Shouldn't this part be uncontroversial? Brains are expensive.
"Beyond mere statistical assertion" So his response to "All the statistics show racial IQ differences" is simply to say "that's irrelevant unless you have a concrete theory to explain why that happened"? A moment's reflection dismissing something as an "unlikely scenario" is exactly the opposite of how science should be done.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
