“Intelligence Tests and the Immigration Act of 1924”, 1983 ():
[cf. 1917] It is often claimed that the racially biased Immigration Act of 1924 was passed with the help of the intelligence-testing community of the period.
The claim consists of 2 components: first, that the intelligence testing community saw its test data on social and ethnic differences as favoring a discriminatory immigration policy and, second, that the US Congress relied to some substantial extent on the testing community and/or its data.
An examination of the historical record failed to uncover any support for either component of the claim: the testing community did not generally view its findings as favoring restrictive immigration policies like those in the 1924 Act, and Congress took virtually no notice of intelligence testing.
