Questions: Eugenics: Pseudoscience, Racial Theory, and Crimes Against Humanity

Question 1

Who coined the term 'eugenics' and in what year?

• A. Charles Darwin, 1859
• B. Francis Galton, 1883
• C. Karl Pearson, 1901
• D. Adolf Hitler, 1925

Answer: (B)

Francis Galton, Darwin's half-cousin, coined 'eugenics' in 1883 in his book 'Inquiries into Human Faculty and Its Development.' Galton had been studying the heritability of intelligence and talent (particularly in eminent families) and concluded that selective human breeding could improve the species. He distinguished 'positive eugenics' (encouraging the 'fit' to reproduce more) from 'negative eugenics' (discouraging or preventing reproduction by the 'unfit').

Question 2

Eugenics programs in the United States sterilized many thousands of people without their consent. Which Supreme Court case upheld the constitutionality of compulsory sterilization laws?

Model answer: Buck v. Bell (1927). The case involved Carrie Buck, a Virginia woman falsely characterized as 'feebleminded' (cognitively disabled) and 'sexually delinquent.' Justice Oliver Wendell Holmes wrote the majority opinion upholding Virginia's forced sterilization law: 'Three generations of imbeciles are enough.' The ruling was never formally overturned. Approximately 65,000 people were forcibly sterilized in the US under eugenic laws, disproportionately targeting poor women, minorities, and people in state institutions.

Buck v. Bell remains one of the most shameful Supreme Court decisions. Historians have established that Carrie Buck was not cognitively disabled — she was an inconvenient young woman whose rape by a family member had produced an illegitimate child. The ruling reflects how eugenic pseudoscience was used to target marginalized people.

Question 3

What were the fundamental scientific errors in eugenic thinking about intelligence and criminality?

Model answer: Eugenicists assumed that complex traits like intelligence, criminality, and 'moral worth' were controlled by single genes or simple combinations, making them highly heritable and selectable. Modern genetics understands these traits as polygenic (influenced by thousands of genes) with massive environmental components — education, nutrition, social stability all substantially affect measured intelligence. Eugenicists also conflated culturally defined categories (criminality is defined by law) with biological traits. Their statistical methods were also crude: correlations between family members in intelligence reflect both genes and shared environments.

The genetics eugenicists used was not just ethically wrong but scientifically primitive. They were working before the Modern Synthesis, without understanding of polygenic traits, quantitative genetics, or gene-environment interaction.

Question 4

Nazi eugenics was a uniquely German phenomenon with no precedents or parallels in liberal democracies.

• T. True
• F. False

Answer: False

Nazi eugenics drew explicitly on American and British eugenic laws. The 1933 German Law for the Prevention of Hereditarily Diseased Offspring was modeled on the American eugenics movement's model sterilization law. American eugenicists like Harry Laughlin testified before Congress and were honored by Nazi Germany. By 1933, roughly 30 US states had compulsory sterilization laws. Sweden sterilized approximately 63,000 people between 1935 and 1975. Nazi racial eugenics was more extreme in its conclusions but emerged from an international eugenics movement.

Question 5

How does the history of eugenics inform contemporary debates about genetic testing, gene editing, and prenatal screening?

Model answer: The history of eugenics raises questions that have not been resolved by its discrediting. Prenatal genetic testing allows prospective parents to select against embryos with particular conditions — which some disability rights advocates argue is a form of eugenics, devaluing lives lived with disability. CRISPR gene editing raises the possibility of 'designer babies' with selected traits. The difference between historical coercive state eugenics and contemporary voluntary individual genetic decisions is real and important — but so is the question of what societal pressures, insurance incentives, or implicit norms might make choices less fully voluntary than they appear.

The eugenics history is not just a cautionary tale about Nazis — it's a standing challenge to think carefully about who decides which traits are worth selecting for, and whether 'voluntary' choices made in a context of social pressure and insurance incentives are as freely chosen as they appear.
