IQ tests were originally developed in France in 1905 by Alfred Binet to assess students' abilities and help teachers. Henry Goddard later popularized the concept of IQ by administering Binet's test to immigrants at Ellis Island in 1913 and concluding that many immigrants from certain countries had low IQs, fueling support for immigration restrictions. The National Origins Act of 1924 established restrictive immigration quotas based on these flawed IQ tests and eugenics theories. It was not until 1965 that immigration laws shifted away from quotas based on national origins.
