Henry Goddard

Photographs of the supposedly "bad" Kallikak branch were retouched to accentuate certain features. Stephen Jay Gould regarded this as contributing to the manufacture of an appearance of degeneration; historian Raymond Fancher showed that such retouching could also have resulted from printing techniques used at the time.

State of the evidence

Disputed

From the 1920s onwards, psychologists, biologists and psychiatrists challenged the simplistic hereditary basis of his models and the robustness of his tests. Goddard gradually left this field, focused more on education and environment, and several historical accounts indicate that he later considered some of his early conclusions outdated or mistaken.

State of the evidence

Documented

Goddard's work was widely cited by the eugenics movement and used as a reference by proponents of forced sterilisation. Historical literature links it to the intellectual climate and arguments preceding, notably, Buck v. Bell in 1927.

Documented

As head of Ohio's Bureau of Juvenile Research, Goddard advocated in official publications the sterilisation and segregation of people he classified as deficient and sought to develop a system in which minors could be assessed and subsequently kept under state control according to their classification.

During the First World War, Goddard participated in the applied psychology movement that introduced Alpha/Beta intelligence tests on a large scale among recruits. The results would be used to support hierarchical interpretations of intelligence and civic fitness among national and racial groups.

Close aide

The programme associated with Goddard administered mental tests to third-class immigrants at Ellis Island and published striking proportions of people classified as deficient within several small samples. These results were taken up amid the nativist and eugenic climate of the period.

Goddard argued that people he classified as deficient should be prevented from reproducing, considering sterilisation and, especially, long-term institutional segregation. His writings contributed to the scientific legitimisation of eugenic policies.

Goddard published The Kallikak Family, presenting a "good" lineage and a "degenerate" lineage as evidence of inherited intellectual disability and social behaviour. Subsequent research revealed major genealogical errors and the absence of a scientific foundation for its argument.

In his research on the inheritance of "feeblemindedness", Goddard applied a simplified hereditary model to complex cognitive and social characteristics. This deterministic Mendelian approach became a cornerstone of American eugenic discourse.

Goddard translated and adapted the Binet–Simon test at Vineland and made it a tool for classifying people considered mentally deficient. He subsequently popularised the category "moron", helping transform experimental psychological measures into tools for social and institutional sorting.
