Psychologists actually have to recalibrate the scoring of IQ tests every few decades in order to keep the average at 100 -- and they need to do this because the scores are going up. I tried to get a psych friend of mine to explain this, because if you follow the implications it means that someone who scored an average IQ in the '20s would now be classified as mentally retarded, which strikes me as insane. But for whatever weight you want to give to this particular measure of intelligence, we're actually getting smarter.
