Imbecile - ex wikipedia


From Wikipedia, the free encyclopedia

For the common or slang use of imbecile, see Idiot.
Imbecile was a medical category of people with moderate to severe intellectual disability, as well as a type of criminal.[1][2] The term arises from the Latin word imbecillus, meaning weak, or weak-minded. It included people with an IQ of 21–50, between "moron" (IQ of 51–70) and "idiot" (IQ of 0–20).[3]
The meaning was further refined into mental and moral imbecility.[4][5] The concepts of "moral insanity", "moral idiocy"," and "moral imbecility", led to the emerging field of eugenic criminology, which held that crime can be reduced by preventing "feeble-minded" people from reproducing.[6][7]
"Imbecile" as a concrete classification was popularized by psychologist Henry H. Goddard[8] and was used in 1927 by United States Supreme Court Justice Oliver Wendell Holmes, Jr. in his ruling in the forced-sterilization case Buck v. Bell, 274 U.S. 200 (1927).[9]
The concept is closely associated with psychologypsychiatrycriminology, and eugenics. However, the term imbecile quickly passed into vernacular usage as a derogatory term, and fell out of professional use in the 20th century[10] in favor of mental retardation.
In recent decades, the phrases "mental retardation", "mentally retarded", and "retarded" initially used in a medical manner, are regarded as derogatory and politically incorrect much like moronimbecilecretindolt and idiot, formerly used as scientific terms in the early 20th century. On October 5, 2010, President Barack Obama signed Senate Bill 2781, known as "Rosa's Law", which changed references in many Federal statutes that referred to "mental retardation" to refer instead to "intellectual disability".[11]
