Unbalanced: http://en.wikipedia.org/wiki/Intelligence_quotient The average IQ scores for many populations have been rising at an average rate of three points per decade since the early 20th century with most of the increase in the lower half of the IQ range: a phenomenon called the Flynn effect. It is disputed whether these changes in scores reflect real changes in intellectual abilities, or merely methodological problems with past or present testing. http://en.wikipedia.org/wiki/Flynn_effect /me wordt wel een beetje moe van het googlen voor andere mensen inmiddels :)
