IQ is often used to express if a person is smart. But is that true? Does IQ measure intelligence? Let's find out!
The precursor of intelligence tests (IQ tests) were developed by Alfred Binet and Theodore Simon.. Okay. After months of work, Binet and Simon created the Binet-Simon Scale, a set of 30 tasks that were representative of typical children's abilities. A few years later, researchers at Stanfort modified Binet's test to measure intelligence in the general population. The term IQ or intelligence quotient was developed. Soon, though, IQ was used to justify eugenics. As a consequence, over 65.000 people in the US with low IQ scores were sterilized. After the second worldwar, IQ tests were further developed. The WAIS test was developed which became the standard IQ test we know today. This test combines the results of multiple cognitive tests in one measurement, a full-scale IQ score. There have been some major insight into IQ scores.
James Flynn discovered that the IQ seems to increase in many developed countries (during the 20th century). Today, this effect seems to have stopped. IQ seems to be slightly correlated with brain volumes, especially in certain brain regions. Moreover, intelligence has been linked to thousands of genes and IQ scores are very similar in twins or between children and parents (once the children become adults). IQ is also impacted by the environment and by motivation. However, IQ has been critizised for only given a very limited view of intelligence. We can argue that IQ does not simply measure one person's capabilities but instead reflects a highly complicated mixture of DNA, environment, motivation and brain anatomy.
