James Flynn discovered that IQ scores are going up about three points every 10 years. This translates into an improvement of two standard deviations of 15 points each from an average IQ of 100 to a very superior score of 130. The increases in IQ scores have been almost exclusively in two subsets or subtests that most require abstract reasoning, similarities and matrices.IQ scores remain the same however as they are regularly normed upward to account for the Flynn effect.
