  • 130 or higher: 2.2% of the population.
  • 120-129: 6.7% of the population.
  • 110-119: 16.1% of the population.
  • 90-109 (Average): 50% of the population.
  • 80-89: 16.1% of the population.
  • 70-79: 6.7% of the population.
  • Below 70: 2.2% of the population.

Psychologist Ulric Neisser, who, during 1995, headed an American Psychological Association task force writing a consensus statement on the state of intelligence research, estimates that if American children of 1932 could take an IQ test normed during 1997 their average IQ would have been only about 80

Considering Ravens, Neisser estimates that if he extrapolates beyond the data, which shows a 21-point gain between 1952 and 1982, an even larger gain of 35 IQ points can be argued.

For example, Dutch conscripts gained 21 points during only 30 years, or 7 points per decade, between 1952 and 1982.
