  > There are plenty of reasons to question whether the Flynn effect (rise in IQ test scores) actually reflects increases in general intelligence rather than testing skills. The Flynn effect appears to reflect increases in general intelligence unless you believe world wide testing scores all have the same bias, across different tests.
