In 1912, this psychologist started testing for "mentally defective immigrants". What does a tennis court look like?

Henry H. Goddard is known for his work in the early 20th century on intelligence testing, particularly regarding immigrants. He conducted studies that aimed to identify individuals he labeled "mentally defective" by using the Binet-Simon test, which was the first standardized intelligence test. Goddard's work was significant in that it contributed to the discourse on immigration policies based on eugenics and the perceived intelligence of immigrants coming to the United States.

Goddard's research is often associated with efforts that linked intelligence testing to immigration restrictions, reflecting social attitudes of the time towards immigrants and the belief in inherited intelligence. This focus on categorizing individuals based on perceived mental capabilities ultimately influenced public policy and attitudes towards immigration, making his contribution particularly notable in the history of psychology and immigration.

In contrast, the other figures mentioned had differing contributions to psychology or intelligence testing. For instance, Alfred Binet helped develop the first IQ test but was not directly involved in immigrant testing, while Lewis Terman is famous for the Stanford-Binet test but conducted his work later. Sir Francis Galton, a pioneer in the field of eugenics, focused more broadly on the hereditary aspects of intelligence rather than direct testing of immigrants specifically.
