Nobody’s suggesting that it’s in any way bad that “different subsets are different”. What’s bad is ignorant and irresponsible scientasters falsely claiming that any valid theory or evidence currently exists that succeeds in scientifically explaining observed racial-group differences in complex traits like intelligence or personality on genetic grounds.
Nope, just a rigorous and consistent standard of proof. If that happens to be impossible to attain, at least in the current state of human neurogenetics research, that’s not our fault. You don’t get to pretend that an unsupported speculation should be taken on trust as a valid theory just because the amount of work required to effectively assess its claim to be a valid theory would be really really really hard.
Not even remotely similar concept. The fundamental chemistry and physics of the theory of anthropogenic global warming is well-established and quite well understood: basically, atmospheric greenhouse gases trap more infrared radiation, humans have produced increased concentrations of atmospheric greenhouse gases, ergo, warming is happening. Other physical phenomena also contribute to warming, but their general cyclic patterns are predictable using the same fundamental chemistry and physics, and their contributions can be at least approximately separated from the anthropogenic contribution with a high degree of confidence. The fact that it’s insanely difficult (and in some cases, not even theoretically possible) to precisely predict the specific direct climate impacts of this warming doesn’t mean that the basic principle is uncertain or poorly understood.
But the basic genetic dependence of human intelligence and other complex psychological traits isn’t understood worth shit. Everybody agrees from empirical studies that intelligence is to some extent genetically heritable. But no researchers have anything even approaching a confirmed hypothesis of which genes affect intelligence and to what extent, how the relevant genes interact with one another and with the environment (which is another hugely complicated subject crawling with irreproducible results and unidentified variables), and so on.
And that’s only talking about the study of direct heritability of intelligence in genetically identical or extremely closely related subjects. It doesn’t even address the whole new cans of worms that are opened up when attempting to detect genetic effects on intelligence at the population level. And trying to extrapolate from that immensely complex issue to all the additional variables involved when considering loosely-defined racial groups that don’t even constitute well-defined genetic populations is an entire next level of heady-splody.
So, no, hell no, the current state of climate science isn’t in the least like the current state of neurogenetic research on genetic bases of human intelligence.
