Original Title: TIL about “Flynn Effect”, which shows that the average IQ rises steadily with each generation. IQ tests are made harder and harder to keep the average at 100. Today’s children taking tests from previous decades score well above 100 on average.
Some parts of IQ tests can measure some aspects of intelligence. But they’re limited and so many things can affect how someone might score on the day. Including but not limited to anxiety, restedness, culture, access to education, bias within the test…
Overall the whole concept of boiling down intelligence to one number seems like a relic of the days when people were measuring skulls to predict criminality and inserting their own weird cocaine fuelled incest fetishes into their theories of psychology.
