i wonder if the many idiots included were people with learning differences autism or dementia
it was obviously an acceptable term
It was an official description of the time along with imbecile and moron
In 19th- and early 20th-century medicine and psychology, an "idiot" was a person with a very profound intellectual disability, being diagnosed with "idiocy".
In their charts it would be in order of disability
1. Moron IQ level 51 - 70
2. Imbecile IQ level 26 - 50
3. Idiot IQ level 0 - 25
