I can disprove several things in the book, but I'm not a liberal. Niggers are still intellectually and behaviourally inferior to humans due to their genome structure.
This popped right up:
Heritability is the amount of variation in a trait due to the genes. A heritability of 1.00 means that the differences are inborn and the environment has no effect. A heritability of zero (0.00) means the trait is controlled by the environment and not at all by the genes. A heritability of 0.50 means that the differences come from both the genes and the environment.
The heritability of a trait is mostly based on both the population and the trait involved.
A heritability of 0 does not mean that a trait is not controlled by genes, it means that the trait is not controlled by genes in a said population. Despite that, it would be pretty hard to drop it to plain 0, whatever it was. That is, if we're actually talking about biological traits. For example, speaking English has a heritability of 0.
A heritability of 1 does not mean that the environment has no effect. Stochastic effects can account for significant differences. E.g., see bacteria culture studies and C. elegans longevity studies. In these examples genetically identical populations (So genes account for no difference.) are grown in the nearly the same environment. And yet there is significant variance in the populations.
Anyway, he only makes that mistake in this short text and not his methodology.
