Study Notes
Kallikak Family Study Notes
Eugenics
- The Kallikak family study was used as evidence to support the eugenics movement in the early 20th century.
- Eugenics aimed to improve the human race through selective breeding and sterilization of those deemed "unfit".
- The study was used to justify forced sterilization of people with low intelligence, criminality, and other perceived social ills.
Intelligence Quotient (IQ)
- The study reported a correlation between IQ and social deviance, suggesting that low IQ was a cause of social problems.
- The average IQ of the "bad" side of the family was reported to be around 70, while the "good" side averaged around 100.
- However, the methods used to measure IQ and the conclusions drawn have been widely criticized as flawed and biased.
Family Dynamics
- The study focused on the Kallikak family, tracing the lineage of a woman named Deborah Kallikak, who had children with a "feeble-minded" man.
- The study claimed to show that the "bad" side of the family, descended from Deborah's illegitimate son Martin, was plagued by feeble-mindedness, crime, and poverty.
- In contrast, the "good" side of the family, descended from Deborah's legitimate son, was portrayed as respectable and successful.
Heredity
- The study aimed to demonstrate the hereditary nature of intelligence, morality, and social behavior.
- It claimed to show that "bad" traits like feeble-mindedness, criminality, and promiscuity were inherited from parents, while "good" traits like intelligence and respectability were also inherited.
- However, modern genetics and psychology have discredited the idea that complex traits can be reduced to simple hereditary factors.

Juke Family
Study Overview
- The Juke family is a pseudonymous family used in a 1916 study to demonstrate the hereditary nature of criminal behavior.
- The study claimed that the family's criminality, poverty, and social problems were due to genetic factors.
Family Origin
- The family was allegedly of Dutch ancestry, tracing back to a Dutch colonist named Adrian "Juke" in the 17th century.
- They settled in Ulster County, New York, and eventually spread throughout the United States.
Genealogy and Study Methodology
- Emma Wolverton constructed the Juke family tree using a combination of interviews, public records, and other sources.
- The study claimed to have identified over 1,200 individuals across seven generations, with a high incidence of criminal behavior, mental illness, and social problems.
- The study has been widely criticized for its methodological flaws, lack of objective data, and racist and eugenicist undertones.
- Modern scholars have disputed the validity of the Juke family study, arguing that it was based on flawed assumptions and cherry-picked data.
