Euphemism Treadmill and Intellectual Disability

 

Why terminology changes:

Terms used for intellectual disabilities can change over time because words

that were originally intended to be clinical, scientific,

 or neutral can acquire negative meanings when society uses them as insults.

This process is often called the euphemism treadmill.

 

1. Older scientific terms

 

Words such as “idiot,” “imbecile,” “moron,” and “feeble-minded”

 were historically used as medical, psychological, educational, or legal classifications.

They did not originally have exactly the same meaning they have today.

 

2. The terms become insults

 

As these words entered everyday language, they increasingly became

 associated with stupidity, incompetence, or worthlessness.

 Eventually,

 they became offensive labels rather than useful descriptions.

 

3. A new term is introduced

 

Professionals and advocates may then adopt a newer term that is

 intended to be more respectful, neutral, and accurate.

 

This creates the euphemism treadmill:

 

Clinical term → becomes stigmatized → becomes an insult →

replaced by a new term → new term may eventually become stigmatized

 

Example: “Mental Retardation”

 

“Mental retardation” was once an accepted professional and governmental term. However,

the word “retarded” increasingly became a derogatory insult.

 

In the United States, Rosa's Law (2010) changed federal terminology,

replacing references to “mental retardation” with “intellectual disability”

in federal laws and regulations. Rosa's Law — GovInfo

 

Modern terminology

 

Today, intellectual disability (ID) is the widely accepted professional term.

 

It is also important to remember that language preferences can differ.

 Person-first language uses phrases such as:

 

“a person with an intellectual disability”

“a person with a disability”

 

However, some people prefer identity-first language, such as:

 

“an intellectually disabled person”

“a disabled person”

 

Neither approach should be assumed to be preferred by everyone.

The Person's own perspective is the most important consideration.

 

Key study point

 

The euphemism treadmill describes how a neutral or clinical term can become stigmatised,

 leading society to replace it with a new term intended to be more respectful.

 

This is a particularly useful concept for understanding why disability

terminology has changed throughout history and why language can

influence how people with disabilities are perceived and treated.
