History of Intelligence Testing
• 1904 Binet-Simon test was created to test French school children in an effort to determine who needed remedial help.
• Less than a decade later Americans modified the test to determine innate intelligence and the IQ test was born. (Stanford-Binet became the leading test)
Why do you think it is that intelligence tests became so popular in America during the 20th century?
Three factors help account for this:
1. Screen incoming immigrants.
2. New laws mandating universal education.
3. Military screening.
