"IN THE MID-’80s, the political philosopher James Flynn noticed a remarkable but puzzling trend: for the past century, average IQ scores in every industrialized nation have been steadily rising. And not just a little: nearly three points every decade. Every several years, IQ tests test have to be “re-normed” so that the average remains 100. This means that a person who scored 100 a century ago would score 70 today; a person who tested as average a century ago would today be declared mentally retarded."
"Why has this happened? The short answer, according to Flynn, is that a convergence of diverse social factors in post-industrial societies—from the emphasis of scientific reasoning in school to the complexity of modern video games—has increasingly demanded abstract thinking. We have begun to see the world, Flynn says, through “scientific spectacles.” To put it even more broadly, the pattern of rising IQ scores does not mean that we are comparing “a worse mind with a better one,” but rather that we are comparing minds that “were adapted to one cognitive environment with those whose minds are adapted to another cognitive environment.” Seen in this light, the Flynn effect does not reflect gains in general intelligence, it reflects a shift to more abstract thinking brought about by a changing social environment. We aren’t getting smarter; we are getting more modern."
