Flynn effect

the gradual cross-cultural rise in raw scores obtained on measures of general intelligence. These increases have been roughly 9 points per generation (i.e., 30 years). The gains have been unequally distributed across the different kinds of abilities, with fluid abilities showing substantially greater gains than crystallized abilities (see Cattell–Horn theory of intelligence). [James Flynn (1934– ), New Zealand philosopher who first documented its occurrence]
