Anyone who doubts that the Flynn effect includes a "real" increase in intelligence ought to just look at the sample tests from 1917.

I would be very interested if someone can look at these tests & do a systematic analysis –- e.g., subtest-level scores, g loadings. The report is massive and poorly organized, so it's hard to find that stuff.
