bad science

In 1912 Henry Herber Goddard published a book called “The Kallikak Family: A Study in the Heredity of Feeble-Mindedness”.

This purported to demonstrate that ‘feeble mindedness’ was hereditary. It was very popular at the time and played to the growing pseudo-science of #eugenics

It was also featured in Nazi propaganda.

Unfortunately the lineage of the Kallikak family that led to the ‘feeble minded’ girl who supposedly started the investigation was a fabrication. Goddard had invented a liaison with a feedle minded barmaid as the source of the ‘feeble minded’ gene.
