This isn’t true. Fraud is by far the likeliest explanation— Jensen’s defense is both strained and interested.

Moreover, this interpretation of heritability is just incorrect. Intelligence could be 100% heritable and yet the phenotype of being intelligence could be totally modifiable!

Put me and a math prodigy in the same room and give us a timed math test— but give me Google, calculators, etc, and I you’ll find our relative performance isn’t predicted by our relative inborn talent.

There are many such cases. Eyeglasses. Hair dye. Plastic surgery. Medicines for genetically predicted diseases. We routinely at every level of our society obliterate or alter the “effects” of genes on people’s lives! The fact that the base phenotype is highly heritable tells us very little about societal modifiability of outcomes! Some low-heritability outcomes are nonetheless EXTREMELY hard to modify!!
