Who are all these people who “consider black folk to be less intelligent than white folk becuase they are black”? You must live in a very racist country.
Most of the
52 people who signed Linda
Gottfredson's 1994 letter to the WSJ ("
Mainstream Science on Intelligence") identified themselves as associated with universities and other institutions located within the United States. Of the 25 numbered statements allegedly "regarded as mainstream among researchers on intelligence", these two may be relevant to your question:
7. Members of all racial-ethnic groups can be found at every IQ level...The bell curves for some groups (Jews and East Asians) are centered somewhat higher than for whites in general. Other groups (blacks and Hispanics) are centered somewhat lower than non-Hispanic whites.
8. The bell curve for whites is centered roughly around IQ 100; the bell curve for American blacks roughly around 85; and those for different subgroups of Hispanics roughly midway between those for whites and blacks. The evidence is less definitive for exactly where above IQ 100 the bell curves for Jews and Asians are centered.
Correlation is not causation, of course, but 20 of the 52 who signed were funded by the
Pioneer Fund, which most definitely promoted the idea of a causal link. (Circa 2022, the Pioneer Fund morphed into the
Human Diversity Foundation, which continues to promote a causal link between race and intelligence.)
As for how mainstream that "Mainstream Science on Intelligence" letter actually was, we should note that Gottfredsen solicited signatures from 131 "experts in intelligence and allied fields". 48 of those experts explicitly refused to sign the letter, and 31 just ignored Gottfredsen's solicitation.
Similar racism persists today. One month ago,
The New York Times reported
recent mishandling of data from an NIH study:
A group of fringe researchers thwarted safeguards at the National Institutes of Health and gained access to data from thousands of children. The researchers have used it to produce at least 16 papers purporting to find biological evidence for differences in intelligence between races, ranking ethnicities by I.Q. scores and suggesting Black people earn less because they are not very smart.
It is of course true that, in the United States, such racism is nowadays most commonly found within the far right. If you turn a blind eye to the US far right, and to those who associate with the far right, then it is just barely possible to remain unaware of how many people still consider black folk to be less intelligent than white folk just because they're black.
