Summers repeats the IQ fallacy. IQ tests are designed to produce male-female IQ equality, based on the assumption that they are equal in the population. If test makers find that female IQ is higher, they change test questions until scores are equalized. Smoke and mirrors.

Implying that correlation means cause, when it doesn’t. Seems like a new version of the 20-year behavioral “candidate gene” fiasco.

Thomas Bouchard, Nancy Segal and colleagues in their very famous 1990 Science Magazine “twins reared apart” IQ study.

And now we're hearing that a foreign government is welcoming Nazi-saluting billionaires, inviting Nazi-led Ukrainian ballations and celebrating them, and holding a conference for the leaders of far-right European anti-semitic parties. The country is called Israel, so nothing to see here.

True, which suggests that the behavioral sciences should take a hard and objective second look at twin studies and their underlying assumptions (EEA). Not to mention the Minnesota "read-apart" twin study, where the researchers hid their control group data to find above-zero IQ heritability.

The main study cited by race scientists in favor of “high IQ heritability” is the 1990 “Minnesota Study of Twins Reared Apart” Science Magazine IQ article. In that study, the researchers hid their control group data to avoid a within-group 0% IQ heritability conclusion. Classic p-hacking maneuver.
