Hold on, do you deny that IQ has a strong heritable component and that there's a well-documented IQ difference between different populations? Cause that's all he's saying, while also emphasizing that these statements mean little when referring to specific individuals.

Lots of problems connecting IQ with race and heritability, well researched. See for example:

the "heritability" of IQ - the degree to which IQ variations can be explained by genes - varies dramatically by socioeconomic class. Heritability among high-SES (socioeconomic status) kids was 0.72; in other words, genetic factors accounted for 72 percent of the variations in IQ, while shared environment accounted for only 15 percent. For low-SES kids, on the other hand, the relative influence of genes and environment was inverted: Estimated heritability was only 0.10, while shared environment explained 58 percent of IQ variations.[1]

This is evidence that we should invest more in early childhood enrichment and healthy food for the poor, so everyone can reach their potential. Genetics determine the capability of your engine, but you still need to feed it with gas.

It doesn’t justify lowering the bar for hiring, creating quota systems, or engaging in positive discrimination.
