History of Intelligence Quotient, Idiot, and Moron
IQ test or intelligence quotient test was developed by physician Théodore Simon and psychologist Alfred Binet in 1905. It was intended as a test to determine the intelligence level of children with special needs. However, the American eugenicist Henry Goddard popularized the concept of IQ as a way to establish grades of mental deficiency. The original scale of IQ measurement introduced by Binet has two grades: idiot and imbecile. Idiots referred to those who had a mental age of 2 or less, while imbeciles referred to those who had a mental age between 3 – 7 years.
However, Godard felt that these two grades were not enough to address the issue of mental deficiency as it did not include a grade to refer to those who had a mental age between 8 – 12 years. According to him, this group was the greatest threat to those who demonstrated a normal mental age. Therefore, he coined his own word – moron – to refer to those who showed a mental age between 8 – 12 years.
What Does Idiot Mean
In general use, we use the word idiot to refer to a stupid person. This is a very informal word. It comes from the Greek word idios, which means “private” or “one’s own.” This word has been in use since the 14th century. However, it has taken on a variety of meanings over the years, referring from “an ignorant person”, to “jester” or “professional fool.” today, we use the word idiot as a synonym for fool, dolt, or halfwit.
This word was used in psychology to refer to those with an IQ level between 0 and 25 and a mental age of 2. However, this classification system is not used in modern psychology.
