Intelligence Quotient (IQ)

IQ Basic Facts:
  • IQ is a score derived from special standardized tests designed to assess intelligence.
  • The term "IQ" was initially suggested by the German psychologist William Stern (1912).
  • The scoring of modern IQ tests is based on a projection of the individual's measured rank on the Gaussian bell shaped curve - where the center value (average) is 100, and the standard deviation is around 15.
Factors associated with IQ Scores:
  • Morbidity and mortality
  • Parental social status
  • Parental IQ.
  • Controversy about how much IQ is inheritable.
IQ Score Uses:
  • Predictor of educational achievement.
  • Predictor of special needs
  • Social science tool - predicting job performance and income.
Flynn Effect:
  • Average IQ scores for many populations have been rising.
  • IQ score inflation is at around a rate of three points per decade.
  • Most improvement has been in the lower half of the IQ range.
  • There is some argument about whether these changes in scores reflect real changes in intellectual abilities.
