If I recall correctly, they have been trending upwards for the the past 100 years (up 30 points but I doubt the average person was clinically retarded) and only relatively recently has started to show a slight decline. IQ tests from 100 years ago are still pretty valid, they use military tests I believe. Double check that. |
