Fred Reed, has a piece critical of IQ, reproduced at American Renaissance.com, which is amazing given that this publication worships IQ, especially the IQ of East Asians. Reed is good on noting the paradoxes of the IQ ideology that Africans have, according to the racial realists, IQ at the mental retardation level, but, most people function fine, and can use modern technology. It indicates a massive cultural bias in the tests, showing that the standard tests are flawed. The religious view of the mean IQ of whites being 100, is just a statistical construct; “white” is never clearly defined, and in past articles, before Covid, I took the rest of the ideology apart. Fred does another good job. IQ is simplistic and reductive, and totally unable to deal with a plastic human brain.
