From 1906 to 1918, Goddard was the Director of Research at the
Vineland Training School for Feeble-Minded Girls and Boys in
Vineland, New Jersey, which was the first known laboratory established to study
intellectual disability. While there, he is quoted as stating: "
Democracy, then, means that the people rule by
selecting the wisest, most intelligent and most human to tell them what to do to be happy." [Italics are Goddard's.] At the May 18, 1910, annual meeting of the American Association for the Study of the
Feeble-Minded, Goddard proposed definitions for a system for classifying individuals with intellectual disability based on
intelligence quotient (IQ). Goddard used the terms
moron for those with an IQ of 51–70,
imbecile for those with an IQ of 26–50, and
idiot for those with an IQ of 0-25 for categories of increasing impairment. This
nomenclature was standard for decades. A moron, by his definition, was any adult with a
mental age between eight and twelve. Morons, according to Goddard, were unfit for society and should be removed from society either through institutionalization, sterilization, or both. Goddard's best-known work,
The Kallikak Family, was published in 1912. He had studied the background of several local groups of people that were somewhat distantly related and concluded that they were all descended from a single
Revolutionary War soldier. Martin Kallikak (a pseudonym) first married a Quaker woman. All of the children who came from this relationship were "wholesome" and had no signs of intellectual disability. Later, it was discovered that Kallikak had had an affair with a "nameless feeble-minded woman". The result of this union resulted in generations of criminals. Goddard termed this generation "a race of defective degenerates". While the book rapidly became a success and was considered for making into a Broadway play, his research methods were soon questioned; within ten years he came to agree with the critics and no longer endorsed his conclusions. It is now accepted that Goddard in fact fabricated the Kallikak data, rendering his conclusions unproven and highly dubious. Goddard was a strong advocate of
eugenics. Although he believed that "feeble-minded" people bearing children was inadvisable, he hesitated to promote
compulsory sterilization – even though he was convinced that it would eliminate intellectual disability – because he did not think such a plan could gain widespread acceptance. Instead, he suggested that colonies should be established where the "feeble-minded" could be segregated. Goddard established an intelligence testing program on
Ellis Island in 1913. The purpose of the program was to identify "feeble-minded" persons whose nature was not obvious to the subjective judgement of immigration officers, who had previously made these judgments without the aid of tests. When he published the results in 1917, Goddard stated that his results only applied to immigrants traveling steerage and did not apply to people traveling in first or second class. He also noted that the population he studied had been preselected, omitting those who were either "obviously normal" or "obviously feeble-minded", and stated that he made "no attempt to determine the percentage of feeble-minded among immigrants in general or even of the special groups named – the Jews, Hungarians, Italians, and Russians"; however, he immediately followed this up by stating that "the figures would only need to be revised (reduced) by a relatively small amount" because "[very obviously high-grade intelligent immigrants] were so small a part of the group [of Ellis Island immigrants] that they did not noticeably affect the character of the group." The program found an estimated 80% of the population of
immigrants studied were "feeble-minded". Goddard and his associates tested a group of 35 Jewish, 22 Hungarian, 50 Italian, and 45 Russian immigrants who had been identified as "representative of their respective groups". The results found that 83% of Jews, 80% of Hungarians, 79% of Italians, and 80% of Russians of the study population were "feeble-minded". The untrue claim that this referred to findings made by Goddard in respect to the greater population of Jewish, Hungarian, Italian and Russian immigrants has been widely publicized. Claims are made that the
Immigration Act of 1924 was strongly influenced by intelligence testing, which was backed up by the
American Psychologist. Goddard also publicized alleged race-group differences revealed by
Army IQ tests (Army Alpha and Beta) during
World War I (the results were, even in their day, challenged as scientifically inaccurate, and later resulted in a retraction from the director of the project,
Carl Brigham) and claimed that the results showed that Americans were unfit for democracy. ==Later career==
