　　It turns out that ants that were marked doing a certain task one day switch to do a different task when conditions change.

　　HOW IQ BECOMES IQ

　　In 1904 the French minister of education, facing limited resources for schooling, sought a way to separate the unable from the merely lazy. Alfred Binet got the job of devising selection principles and his brilliant solution put a stamp on the study of intelligence and was the forerunner of intelligence tests still used today. He developed a thirty-problem test in 1905, which tapped several abilities related to intellect, such as judgment and reasoning. The test determined a given childs mental age. The test previously established a norm for children of a given physical age. For example, five-year-olds on average get ten items correct, therefore, a child with a mental age of five should score 10, which would mean that he or she was functioning pretty much as others of that age. The childs mental age was then compared to his physical age.

　　A large disparity in the wrong direction might suggest inability rather than laziness and means that he or she was earmarked for special schooling. Binet, however, denied that the test was measuring intelligence and said that its purpose was simply diagnostic, for selection only. This message was however lost and caused many problems and misunderstandings later.
