Dr. Francis is either unfamiliar with, or being profoundly misleading of, expert opinion, as surveys show:
"In the current study, EQCA experts wereasked what percentage of the US Black-White differences in IQ is, in their view, due to environment or genes. In general, EQCA experts gave a 50–50 (50% genes, 50% environment) response with a slight tilt to the environmental position (51% vs. 49%; Table 3). When EQCA experts were classified into discrete categories (genetic, environmental, or 50–50), 40% favored an environmental position, 43% a genetic position, and 17% assumed 50–50." - https://doi.org/10.1016/j.intell.2019.101406
> I think this video [1], does a good job of attacking a lot of race science and intelligence
'Attacking' is a good description, as the author of that video went to great lengths to mislead. For example, he says the author of The Bell Curve doesn't understand what 'hereditary' means. But the definition the video author gives for 'hereditary', and the definition given in the book he's reviewing, match almost perfectly. So how did he come to that conclusion? He went out of his way to find a live interview where the book author fumbled his answer, instead of giving the definition from the book he's reviewing, or as you more accurately put it, attacking.
