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.
