The name of a famous eugenics
study in 1912. Martin Kallikak was a well-known Quaker
. He had relations
with a 'dullard', siring children, then settled down
with 'an industrious
Quaker maid'. The legitimate
children were judged to be successful
, the illegitimate
children less so. Since the kids
grew up two miles apart, researchers
concluded that the environment
was the same, and therefore the only variable
was the genes
of the mother.
The 'successful' Kallikaks, some of which where judges and professors, had few children. The illegitimate Kallikaks often had many children. This gave creedence to the theories that idiots replicate faster than smart people.
The studies were published with photographs. The 'unsuccessful' side of the family were shown as unattractive and sinister-looking, and the 'successful' side of the family was shown to be more attractive. This alone swayed many opinions.
