Folks tested in the 40's and 50's averaged IQ 70. Were they dumber then? Or just not as test-savvy, having less exposure to education, logic etc? What we call IQ today can be boosted by exposure to more cognitive tools (memorization, speed reading, puzzles and games)

Are you talking their averages then scaled with current averages? I thought IQ was averaged around 100. I'm on mobile with a spotty connection right now, so I can't look much up at the moment. I am doing well to reply on my fourth attempt.

SOme previous HN post about old intelligence test results, filed away for 60 years. Rescored, those people who took those tests long ago, had an average IQ of 70.
