Thanks to this process, institutions of all kinds have had to repeatedly change their names. This affects the names of schools, hospitals, societies, government departments, and academic journals. For example, the Midlands Institute of Mental Subnormality became the British Institute of Mental Handicap and is now the British Institute of Learning Disability.
The euphemism treadmill is likely to continue until societal ableism stops.Futshane, Lusanda. Inclusive language: outrunning the euphemism treadmill, League DigitalPeterson, Ashley. What Is… the Euphemism Treadmill, Mental Health @ Home
