In the United Kingdom, a study by Flynn (2009) himself found that tests carried out in 1980 and again in 2008 show that the IQ score of an average 14-year-old dropped by more than two points over the period. For the upper half of the results, the performance was even worse. Average IQ scores declined by six points.
Americans’ IQ scores are trending in a downward direction. In fact, they’ve been falling for over a decade. According to a press release, in studying intelligence testing data from 2006 to ...
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.
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.
For comparison, the average IQ is around 100. Albert Einstein and Stephen Hawking ranked close to 160. ... Modern psychologists pointed out flaws in the science of IQ testing, discovering that ...
The intelligence paradox – the Flynn effect shows significant improvements in IQ over a short time scale, yet we do not notice in everyday life that young people are significantly smarter than their parents or grandparents. The mental retardation paradox – the IQ level commonly associated with mental retardation is 75. If the Flynn effect ...
Measures such as mental age and IQ have limitations. Binet did not believe these measures represented a single, permanent, and inborn level of intelligence. He stressed that intelligence overall is too broad to be represented by a single number. It is influenced by many factors such as the individual's background, and it changes over time. [9]
