These hardly seem consistent. (It's the last claim I'm challenging.) 'Intelligence testing' had barely gotten off the ground in 1905; the term 'intelligence quotient' had not yet been coined; the refinement of Alfred Binet's work (which had only been completed in 1905) by Lewis Terman and others, work which resulted in the 'Stanford-Binet' test, was made known in 1916.
What I'm suggesting is that if the first two statements are true, the third could not really be knowable, given not only the adjustments that would have had to have been made between any intelligence assessments done in 1905, and the various instruments used today, but the lack of a sufficiently large sample of the population who might somehow have taken an 'intelligence test.' The statistical insouciance here is fairly astonishing.
In short, who and how many took 'intelligence tests' in the US in 1905; and how were 1905 numerical assessments of 'intelligence' made comparable with those made today?
P p.s. I'm glad you're still here to RP.
