    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.
