Doing so confirms IQ gains over time. Some IQ tests - for example, tests used for military draftees in NATO countries in Europe - report raw scores, and those also confirm a trend of rising scores over time. The average rate of increase seems to be about three IQ points per decade in the United States, as scaled by the Wechsler tests.
The Flynn effect is the increase in average intelligence test scores by about 0.3% annually, resulting in the average person today scoring 15 points higher in IQ compared to the generation 50 years ago. [61] This effect can be explained by a generally more stimulating environment for all people.
The 1981 article "Average IQ values in various European countries" by Vinko Buj is the only international IQ study that over a short time period has compared IQs using the same IQ test. Rindermann (2007) states that it is of dubious quality with scant information regarding how it was done.
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
Such non-verbal tests can be used to compare diverse populations such as San people and Inuktun. In 1987, Flynn published "Massive IQ Gains in 14 Nations: What IQ Tests Really Measure", which found that IQ points in 14 countries, as measured by Raven tests, increased between five and 25 points.

A 2014 study of 600 college students found that individuals who identified as "dog people" were more outgoing than those who identified as "cat people," according to a test that measures ...
The much-discussed "Flynn effect", which refers to the striking worldwide mean IQ increase over time, seemed too large to have simply reflected increased test sophistication. Possible explanations included improved nutrition and more complex environment. It was also unclear to what degree the IQ increase reflected real gain in intelligence.
