Abstract:Data from two samples of 32,862 and 6,757 males, respectively, from the Danish draft board indicate that gains in intelligence test scores are continuing and are concentrated among lower intelligence levels. Monte Carlo simulations suggested that this distributional change did not result from a ceiling effect in the test. (SLD)
