So the last post I wrote was focused on Eric Turkheimer's bet over hereditarian beliefs with Charles Murray and hereditarian Murray lost. Although of course he can't admit it.
Meanwhile, Steven Pinker is promoting hereditarian ghoul Scott Alexander Siskind's website Slate Star Codex, while claiming that hereditarians have won.
Because there is no data that will convince gutter racists like Murray and Pinker that their "hereditarian hypothesis" is incorrect.
Both Pinker and Siskind like to promote hardcore racists Emil Kirkegaard and Jordan Lasker (Cremieux.)
We've already seen that Pinker has no shame about participating in the neo-Nazi magazine/podcast Aporia.
And in the Slate Star Codex post Pinker links to from X, Siskind does his part in promoting neo-Nazi ideology pretending to be science:
Emil and Cremieux argue that we know why this study found low heritability of IQ. It’s because you can’t give 347,630 people a full-length IQ test. So they gave these people a short crappy IQ-like test with a lot of random noise. Past studies estimated the reliability of this test at 0.61 (low). It’s easy to statistically correct for this; when you do so, you find that if the test had been better, this study would have estimated the heritability of IQ at 55%. This is still on the low end, but it’s already within the hereditarians’ estimate of 50 - 80%, and there are a few other biases that might be bringing it down too (eg healthy volunteer bias).
3. And Emil Kirkegaard crunches some numbers that broadly support the latest discussion on here about non-shared environment.
