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.
