Intellectual disability

mental retardationintellectually disabledintellectual disabilities
Imbecile indicated an intellectual disability less extreme than idiocy and not necessarily inherited. It is now usually subdivided into two categories, known as severe intellectual disability and moderate intellectual disability. Moron was defined by the American Association for the Study of the Feeble-minded in 1910, following work by Henry H. Goddard, as the term for an adult with a mental age between eight and twelve; mild intellectual disability is now the term for this condition. Alternative definitions of these terms based on IQ were also used. This group was known in UK law from 1911 to 1959–60 as feeble-minded.


Binet and Simon introduced the concept of mental age and referred to the lowest scorers on their test as idiots. Henry H. Goddard put the Binet-Simon scale to work and introduced classifications of mental level such as imbecile and feebleminded. In 1916 (after Binet's death), Stanford professor Lewis M. Terman modified the Binet-Simon scale (renamed the Stanford–Binet scale) and introduced the intelligence quotient as a score report. From this test, Terman concluded that mental retardation "represents the level of intelligence which is very, very common among Spanish-Indians and Mexican families of the Southwest and also among negroes. Their dullness seems to be racial."

Goddard used the term "feeble-minded" to refer to people who did not perform well in the test and thus were intellectually inferior. He argued that "feeble-mindedness" is caused by heredity, thus feeble-minded people should be prevented from giving birth, either by institutional isolation or sterilization surgeries. At first sterilization targeted the disabled and was extended to poor people. Goddard's intelligence test was endorsed by the eugenicists to push for laws for forced sterilization. Different states adopted the sterilization laws at different pace. These laws forced over 64,000 people to go through sterilization in the United States.

Goddard used the terms moron for those with an IQ of 51-70, imbecile for those with an IQ of 26-50, and idiot for those with an IQ of 0-25 for categories of increasing impairment. This nomenclature was standard for decades. A moron, by his definition, was any adult with mental age between eight and twelve. Morons, according to Goddard, were unfit for society and should be removed from society either through institutionalization, sterilization, or both. Goddard's best-known work, The Kallikak Family, was published in 1912.

Glenwood, Iowa

GlenwoodCity of GlenwoodGlenwood (Iowa) Lake Park
By 1925, the Glenwood IIFMC was the home of 1,555 inmates classified as idiots, imbeciles, and morons, according to contemporary definitions. The IIFMC became the Glenwood State-Hospital School in 1941. By the early 1950s, the facility covered 1185 acre; it had 310 staff members for the 1,968 patients. Under the influence of eugenics theory, the state had ordered sterilization of those defined as feeble-minded or worse, and experimental treatments such as cold baths and electroshock were used to reduce symptoms of psychosis and depression. The de-institutionalization of Glenwood began in the late 1950s.

Ellis Island Immigrant Hospital

Some of the contemporary clinical classifications for mental illness are now archaic: idiot, imbecile, moron, or feeble-minded. It is likely that many of these immigrants were not actually mentally ill, but that cultural differences and a language barrier, as well as the immigrants’ anxiety about a new country, made them appear mentally ill. More objective testing methods were developed by Dr. Howard Andrew Knox to determine with increased accuracy whether an emigrant was mentally deficient. The Knox tests were effective in that they did not require specific cultural knowledge for successful performance.

The International Classification of Diseases (ICD) is the international "standard diagnostic tool for epidemiology, health management and clinical purposes." Its full official name is International Statistical Classification of Diseases and Related Health Problems.


A euphemism is a generally innocuous word or expression used in place of one that may be found offensive or suggest something unpleasant. Some euphemisms are intended to amuse, while others use bland, inoffensive terms for concepts that the user wishes to downplay. Euphemisms may be used to refer to taboo topics (such as disability, sex, excretion, or death) in a polite way, or to mask profanity.

Eugenics in the United States

American eugenics movementeugenicseugenics movement
Beginning with Connecticut in 1896, many states enacted marriage laws with eugenic criteria, prohibiting anyone who was "epileptic, imbecile or feeble-minded" from marrying. The first state to introduce a compulsory sterilization bill was Michigan, in 1897 but the proposed law failed to garner enough votes by legislators to be adopted. Eight years later Pennsylvania's state legislators passed a sterilization bill that was vetoed by the governor. Indiana became the first state to enact sterilization legislation in 1907, followed closely by Washington and California in 1909.

This expression was not an accurate description of that verdict. 1886 - The Idiots Act 1886 (49 Vict.c.25) was an act of Parliament of the United Kingdom. It was intended to give "... facilities for the care, education, and training of Idiots and Imbeciles". The Act made, for the first time, the distinction between "lunatics", "idiots", and "imbeciles" for the purpose of making entry into education establishments easier and for defining the ways they were cared for.

Mental Deficiency Act 1913

In 1904 the Royal Commission on the Care and Control of the Feeble-Minded was set up with the warrant "to consider the existing methods of dealing with idiots and epileptics, and with imbecile, feeble-minded, or defective persons not certified under the Lunacy Laws... to report as to the amendments in the law or other measures which should be adopted in the matter". The Commission returned a lengthy report in 1908 which estimated that of a population of 32,527,843 British inhabitants 149,628 people (0.46%) were considered "mentally defective".

1910 in science

May 18 – At the annual meeting of the American Association for the Study of the Feeble-Minded, Henry H. Goddard introduces a system for classifying individuals with mental retardation based on intelligence quotient (IQ): moron for those with an IQ of 51-70, imbecile for those with an IQ of 26-50, and idiot for those with an IQ of 0-25. July 15 – Publication of the eighth edition of Emil Kraepelin's Psychiatrie: Ein Lehrbuch für Studierende und Arzte, naming Alzheimer's disease as a variety of dementia. Late December – A form of pneumonic plague spreads through northeastern China, killing more than 40,000. Thomas Hunt Morgan discovers that genes are located on chromosomes.

The Act was repealed by the Mental Deficiency Act 1913, by which time two further classifications had been introduced: "feeble-minded people" and "moral defectives". ;Notes

Howard Eskin

He frequently refers to a caller as a "genius" or "chief" (both sarcastically), a "dope", an "idiot", a "nitwit", a "creep" or a "moron". He is known to ask female callers about preparing dinner or washing the laundry and he calls obviously black callers "dawg" while sarcastically closing those conversations with the urban vernacular term "holla". In addition, Italian callers are often addressed as "cuzz" and Dallas Cowboys' fans are termed "cock-a-roaches". Howard at times will tell callers if they are worried about their team, "If you're scared, get a dog."

Buck v. Bell

US Supreme Court ruling of Buck v. Bell
The sterilization law was only for the "feeble-minded" at certain state institutions and made no mention of other state institutions or those who were not in an institution. On May 2, 1927, in an 8–1 decision, the Court accepted that Buck, her mother and her daughter were "feeble-minded" and "promiscuous," and that it was in the state's interest to have her sterilized. The ruling legitimized Virginia's sterilization procedures until they were repealed in 1974. The ruling was written by Oliver Wendell Holmes, Jr.

Compulsory sterilization

forced sterilizationsterilizationcompulsory sterilisation
At this time, there were many women that were sent to institutions under the guise of being “feeble-minded" because they were promiscuous or became pregnant while unmarried. Some sterilizations took place in prisons and other penal institutions, targeting criminality, but they were in the relative minority. In the end, over 65,000 individuals were sterilized in 33 states under state compulsory sterilization programs in the United States, in all likelihood without the perspectives of ethnic minorities. The first state to introduce a compulsory sterilization bill was Michigan, in 1897, but the proposed law failed to pass.

Rosa's Law

Words such as idiot and moron were common in court documents and diagnosis throughout the early 1900s. In the 1960s, changes in the law led to the use of such terms as mental retardation. With the loss of idiot (IQ 0-25), imbecile (IQ 26-50) and moron (IQ 51-75), specific descriptors of IQ-based intelligence were abandoned because of public sentiment. Under Rosa's law, these would be described respectively as profound, severe and moderate levels of intellectual disability. Imbecile. Developmental disability. Feeble-minded.


reasoningratiocinationhuman reason
Reason is the capacity for consciously making sense of things, establishing and verifying facts, applying logic, and changing or justifying practices, institutions, and beliefs based on new or existing information. It is closely associated with such characteristically human activities as philosophy, science, language, mathematics, and art and is normally considered to be a distinguishing ability possessed by humans. Reason, or an aspect of it, is sometimes referred to as rationality.
